Plumber Surprise: the five local rules that decide what a leak costs you

Most city pages on this site open with a rate comparison because the ordering of the water and sewer rates usually decides how expensive a plumbing failure turns out to be. Surprise breaks that pattern harder than any city we have written up. Here a household does not pay a sewer rate at all. Not a cheap one. There is no per gallon sewer charge on a single family home in the City system.

That single design decision changes what you should worry about, what a running toilet actually costs, and why the same fault in a restaurant on Bell Road costs roughly twice what it costs in the house behind it. It also means half of the standard advice about leaks, written for cities that meter sewage, is simply not describing your bill.

Everything below comes from the City of Surprise adopted rate schedule, its water and wastewater pages, its cross connection programme, its adopted building codes and its own annual wastewater report. Where we have done arithmetic on the City figures we say so in the sentence that contains it. Where the City does not publish something we say that too, instead of filling the gap with a number that sounds right.

Nothing here describes an office, a crew, a response time or a guarantee of ours in Surprise. What it describes is the local rule set, because in this city the rule set is unusual enough that knowing it changes what you do first.

The Rate Structure

Water is metered in four tiers. Residential sewer is not metered at all

For the year running 1 July 2026 to 30 June 2027 the City charges a monthly water base of $31.77 on a five eighths inch or three quarter inch meter, which covers most houses. Volume is then billed in four bands: $2.61 per thousand gallons for the first 10,000, $5.16 for the next 10,000, $6.00 for the next 10,000 and $7.19 for everything above 30,000.

Residential wastewater is a single flat base charge of $28.69 a month. Read the adopted schedule and there is no volumetric column against single family at all. Multi family is $25.20 per unit and an RV resort space is $14.44, both flat in the same way.

Our arithmetic on those two lines: the top water band at $7.19 is about 2.75 times the first band at $2.61, so water gets steeply more expensive as you use more. Sewer does not move by a cent. That is the whole shape of a Surprise bill in two sentences.

The adopted residential schedule, and how much of it is fixed

Monthly charge, City of Surprise system 1 Jul 2025 to 30 Jun 2026 1 Jul 2026 to 30 Jun 2027
Water base, 0.625 inch and 0.75 inch meter $30.26 $31.77
Water base, 1 inch meter $39.34 $41.31
Potable water, first 10,000 gallons $2.49 per 1,000 gal $2.61 per 1,000 gal
Potable water, 10,001 to 20,000 gallons $4.91 per 1,000 gal $5.16 per 1,000 gal
Potable water, 20,001 to 30,000 gallons $5.71 per 1,000 gal $6.00 per 1,000 gal
Potable water, over 30,000 gallons $6.85 per 1,000 gal $7.19 per 1,000 gal
Wastewater, single family $27.32 flat $28.69 flat
Wastewater, multi family per unit $24.00 flat $25.20 flat
Solid waste, per can $28.68 $30.11
Stormwater, per equivalent dwelling unit $2.75 $2.75

Notice what that table does before you use any water. A house on a three quarter inch meter owes $31.77 for water access and $28.69 for sewer access, which is $60.46 of fixed monthly charge. Our division: a household using 8,000 gallons a month adds only $20.88 of volumetric water on top, so roughly 74 per cent of a normal Surprise water and sewer bill is fixed cost that no amount of careful use will reduce.

That has a practical consequence people get wrong. Fixing a slow drip will not meaningfully move a normal bill here, because most of a normal bill is not usage. What moves a Surprise bill is a failure large enough to push you out of the first band and up through the other three. The cost of a leak in this city is not linear and it is not gentle.

The stormwater fee is worth one line because it is the only charge on the list that has nothing to do with your plumbing. It is $2.75 per equivalent dwelling unit and holds at $2.75 from FY2025 through FY2029. A single family residence counts as one unit. Commercial, industrial, schools, churches and agricultural land are counted at one unit per 3,420 square feet of impervious area, and undeveloped land is exempt.

The Mechanism That Matters

What a running toilet actually costs in Surprise

Take a household running 8,000 gallons a month, which sits comfortably inside the first water band. Water base $31.77 plus eight thousand gallon units at $2.61 is $52.65. Sewer is $28.69. Water and sewer together come to $81.34 before solid waste and stormwater. That is the normal month.

Now add a continuously running toilet. Utilities commonly put a running toilet in the region of 1,000 gallons a day, and over a thirty day month that is 30,000 extra gallons, taking the house to 38,000 gallons. The City does not publish a gallons per day figure for a running toilet, so treat the 1,000 as a working assumption of ours rather than a Surprise number.

Our arithmetic on the City adopted table. 38,000 gallons bills as 10,000 at $2.61 which is $26.10, plus 10,000 at $5.16 which is $51.60, plus 10,000 at $6.00 which is $60.00, plus 8,000 at $7.19 which is $57.52. Volumetric water is $195.22. Add the $31.77 base and water is $226.99. Sewer stays at $28.69.

So the bill moves from $81.34 to $255.68. The damage is $174.34 and every cent of it lands on the water line. In a city that meters sewage, that same 30,000 gallons would have arrived twice, once as water and once as wastewater. Here it arrives once.

The practical reading is not that leaks are cheap in Surprise. It is that they are cheaper than the generic advice assumes, and that the tier structure rather than the sewer rate is what hurts. The last 8,000 gallons of that leak cost $7.19 each while the first 10,000 cost $2.61 each. A leak that has been running for two months is not twice as expensive as one month, it is worse than that, because the second month starts high instead of starting at the bottom band.

There is a second reading that matters if you are the kind of household that irrigates. Outdoor water in most cities carries a sewer penalty that has to be argued away. In Surprise it does not, because there is nothing to argue away. An irrigation leak and an indoor leak cost exactly the same per gallon, which is unusual, and it means you should chase whichever one is bigger rather than whichever one is indoors.

Surprise commercial wastewater rates set by business type

The Commercial Inversion

If you run a business, your sewer rate is set by what you do

Households pay no volume rate. Commercial customers pay one, and Surprise publishes it as a tariff by business type rather than a single figure. For 1 July 2026 to 30 June 2027 the range runs from $2.55 per thousand gallons for a carwash to $7.50 for a funeral home.

Restaurants and bakeries, industrial and manufacturing and mixed use retail all sit at $7.18. Grocery retail and wholesale is $6.85. Hospitals, convalescent and assisted living is $3.61, a hotel is $3.47, a church or an HOA community facility is $3.28, medical offices are $3.85, professional office and storage or warehouse are $3.10, schools, parks and recreation are $2.99 and laundromats are $2.73.

We are not going to explain why a carwash is cheaper than a funeral home. The City publishes the rates and does not publish the reasoning, and inventing a rationale for somebody else’s tariff is exactly the kind of plausible filler this page avoids.

The number that should change how a restaurant treats a leak

Put the two schedules side by side. A restaurant in Surprise pays $7.18 per thousand gallons of wastewater. The top potable water band is $7.19 per thousand gallons. Our comparison of the two published lines: for a commercial kitchen already using enough water to sit in the top band, a wasted gallon costs $14.37 rather than $7.19. It arrives twice and the two halves are within a penny of each other.

That is the single most useful thing on this page for anyone running a food business here. The same dripping pre rinse valve that costs a homeowner $7.19 per thousand gallons costs you almost exactly double, and none of the household reasoning above applies to you.

And a strength surcharge most businesses have never heard of

  • The City publishes a separate calculation for non residential wastewater customers who are not listed under the commercial business listing.
  • It applies where the strength of the wastewater exceeds a Biochemical Oxygen Demand and a Total Suspended Solids figure of 150 parts per million respectively.
  • The published components are $0.6839 per pound of BOD, $0.3232 per pound of TSS, then per thousand gallons a Flow charge of $0.3048, a Capital charge of $0.9058 and an Administrative charge of $0.4094.
  • If your process discharge is strong and your business type is not on the list, your sewer bill is calculated from what is in the water, not just how much of it there is.

We refuse to state which businesses in practice fall into the strength calculation, or how the City samples for it, because neither was published on the pages read. Ask Water Resource Management on 623.222.6000 before you assume you are on the business type list.

The Boundary Question

Ten other water providers serve addresses inside this city

The City states plainly that it operates and maintains the water system and billing services for the City water, sewer and sanitation utilities, and that there are ten additional water service providers in the City special planning areas. A Surprise address does not tell you who sells you water.

The City directs residents to its My Surprise Address lookup to find their provider, and repeats the instruction on the drinking water page, the wastewater page and the arsenic page. When a city says the same thing three times in three places, it is because people keep getting it wrong.

Wastewater is the other way round. The City says it owns and operates the majority of the wastewater infrastructure within its incorporated boundaries. So the common pattern here is a household whose sewer bill comes from the City and whose water bill does not.

Surprise AZ water and sewer provider split across special planning areas

The fee schedule quietly proves the split

You do not have to take the provider warning on trust, because the City own fee table is built around it. Establishing service costs $21.00 per service. For a City of Surprise customer that comes to $63.00, which is three services. For a customer on third party water it comes to $42.00, which is two. The fee itself counts how many utilities the City is actually selling you.

The delinquent notice fee is $6.30 for a City of Surprise account and $12.60 for a third party water account, exactly double. The City does not explain the difference and we are not going to guess at it. A delinquent shutoff and reconnect fee appears in the schedule specifically named for EPCOR at $113.66, or $154.07 after hours.

What this means at two in the morning. Before you can report a water emergency you need to know which utility owns the meter, and that is a question you should answer on a calm afternoon rather than standing in a wet garage. The City lookup returns your water and sewer provider along with your parcel number and council district.

There is a third possibility the wastewater page names and most residents never consider. For areas that do not have a wastewater service provider at all, the City points people to the Maricopa County Environmental Services Department On Site Wastewater Program on 602.506.6616. If that is your address, you are on a septic system, the City is not your sewer authority, and a backup is a county regulated matter rather than a city one.

The same special planning area structure shows up in the treatment network. The City 2024 Annual Wastewater Report states there are four treatment plants spread across the city, which it attributes to the widespread nature of Surprise and to treatment capacity. The SPA-3 plant in the northwest serves 3,192 customers across 86.12 square miles, treats an average of 290,000 gallons a day and is designed for 1.8 million. It runs a Sequencing Batch Reactor process, a fill and draw activated sludge system, which the report notes differs from the process used at the SPA-1 plant.

One more structural split lives in the rate table. There is a separate base charge schedule headed Circle City customers only, and it is being phased. A five eighths inch meter there was not applicable in FY2025, then $12.20, then $19.86 in the current year, then $27.47, reaching $35.03 in FY2029, which is the same figure the citywide schedule reaches. So Circle City customers are on a four year ramp to parity. The City does not publish the reason on the rates page and we do not state one.

Surprise AZ adopted plumbing code editions and effective date

What Comes Out Of The Tap

Three sources on paper, one source in practice

The City lists three available water sources: groundwater, reclaimed water and Colorado River water delivered as surface water through the Central Arizona Project. It then says something most cities would bury: currently, Surprise relies solely on groundwater for drinking water purposes.

Reclaimed water goes to agricultural and landscape irrigation, and some surface water is used for irrigation too. The adopted schedule reflects that with a separate non potable volumetric rate of $2.19 per thousand gallons at every tier, flat, under an Effluent Reuse Agreement dated 1989.

Groundwater only is the fact that makes the next section make sense. It is also why a Surprise property can have purple pipe running past it carrying water that is deliberately not drinking water, which is a live cross connection risk rather than a theoretical one.

Arsenic, and why the City built plants to take it out

Arizona groundwater carries naturally occurring arsenic and Surprise says so directly. The City publishes a dedicated arsenic page which records that the federal standard was tightened in 2001 from 0.050 milligrams per litre to 0.010, which is 10 parts per billion, and that the occurrence of arsenic in water supplies is not unusual in Arizona.

Where levels exceeded the tightened standard the City built coagulation and filtration arsenic treatment facilities. The published description of the process is specific: a chemical is added to the well water to form particles, those particles are filtered out, the filters are backwashed, the reject water settles in tanks and the settled sludge goes to landfill as non hazardous waste. The City names two of its systems, the Desert Oasis Public Water System PWS number 07-523 and the Mountain Vista Public Water System PWS number 07-500, and states that both meet all state and federal drinking water requirements.

A dating problem we are flagging rather than hiding. The arsenic page carries a line saying permanent arsenic treatment facilities will be in place at Mountain Vista by August 2009. That is a forward looking statement from a page that has clearly not been rewritten since. We report it as published and we do not present it as current status. For the present position, read the current Drinking Water Quality Report or call 623-222-6000.

We refuse to give a hardness figure for Surprise. No City page read for this build published one, and hardness is the number households most want because it decides water heater life, fixture scaling and whether a softener is worth buying. Guessing it from a neighbouring West Valley city would be inventing a local fact, and West Valley groundwater is not uniform enough for that to be honest. Ask your own provider, which on many Surprise streets is not the City.

We also refuse every drinking water constituent value, the current arsenic results, the lead and copper service line inventory and the capacity of any treatment plant other than the SPA-3 figures quoted above, because none of them appeared on the pages read for this page.

The Programme Worth Knowing About

The City has paid for private plumbing repairs, and the programme is currently paused

The Surprise Water Resource Management Department runs a Plumbing Support Grant aimed at helping low income families correct plumbing issues at their homes that are creating water waste. A qualifying household is eligible for up to $1,500 of approved indoor plumbing or outdoor irrigation repair services.

The published list of qualifying issues is short and practical: dripping faucets, running toilets, irrigation leaks and unexplained high water bills. Permission to verify leaks with your water provider is required, and the City defines water waste as continuous consumption events noted by your water provider, or a leak verified by that provider.

Read this before you plan around it. The City page currently carries a notice stating that all plumbing support grant funds have been dispersed, that Water Resource Management is placing a hold on applications, and that applications will be accepted again once programme updates have been completed. We are reporting a suspended programme as suspended rather than describing it as if the money were sitting there.

Eligibility is income tested against published Area Median Income figures, which the City labels as 2022-23 guidelines: $62,200 for a single person household, $71,050 for two, $79,950 for three, $88,800 for four, $95,950 for five, $103,050 for six, $110,150 for seven and $117,250 for eight. Funding is described as limited and administered first come, first served.

The route in is a completed Plumbing Assistance Application emailed to conservewater@surpriseaz.gov, and the department can be reached on the same address or on 623.222.7159. If the hold has lifted by the time you read this and you meet the income test, it is worth an email before you commission anything, because the grant covers approved repair services rather than reimbursing whatever you have already had done.

We are not a party to this programme, we are not on any City list, and we make no claim about whether work of ours would or would not qualify. If the grant matters more to you than who does the work, contact the department first and let them tell you how it operates now.

The Deadline People Miss

Forty eight hours from meter set to tested backflow device

Surprise publishes a cross connection and backflow programme with a deadline sharp enough to catch people out. Its wording is that after the City has set the meter, backflow protection devices are to be tested within 48 hours, and reports submitted to Environmental within 48 hours.

The general rule sits on top of that. A test must be completed on each backflow preventer before it is put into service, after any repair, and at meter installation, then a minimum of once a year thereafter. If a device is replaced, a new certification is required.

Responsibility is stated as the owner’s, not the plumber’s and not the City’s. The owner must make sure devices are tested, testing must be by an approved and certified tester on a current certified and calibrated gauge, and copies of the report go to the owner, the water provider and the tester.

Surprise AZ backflow testing deadline after a meter is set

Permits, codes, and the credential Surprise borrows from Phoenix

Surprise adopted the 2024 International Codes on 2 December 2025 under Ordinance 2025-14, effective 1 January 2026. For plumbing work that means the 2024 International Plumbing Code, the 2024 International Residential Code and the 2024 International Fuel Gas Code, alongside the 2023 National Electrical Code and the 2017 edition of ICC A117.1. Local amendments exist and are on file at the City Clerk office, and they were not read for this page, so nothing here should be treated as covering them.

The more interesting thing is how a permit gets approved. Surprise runs a Self-Certification Building Permit Program which eliminates plan review, and the eligibility condition is unusual: it is open to licensed design professionals certified with the City of Phoenix. Arizona licensed design professionals must attend a self certification training class offered by Phoenix in order to qualify.

Why that is worth a paragraph. Other cities on this site either review your plans themselves or let their own registered professionals self certify. Surprise recognises a neighbouring city’s credential instead of issuing its own. Compare the arrangement on our Chandler plumbing page, where registered design professionals self certify under Chandler’s own scheme.

Where it applies, the City states permits can be issued within five business days, and that self certification eliminates the plan review fees. The published benefit list also puts responsibility squarely on the certified professional, who takes responsibility for and certifies a project compliance with building code, standards and ordinances.

Projects the City lists as NOT eligible for self certification

  • Hazardous occupancies.
  • New high rise buildings, defined as an occupied floor more than 75 feet above Fire Department access.
  • Projects located within a flood plain.
  • Hillside development.
  • Extra large assembly occupancies, categories A4 and A5.
  • Fire alarms and sprinkler systems.
  • Any project where construction has already taken place without the benefit of a permit.

That last exclusion is the one to remember on a plumbing job. Unpermitted work does not just cost you a fee later, it removes your access to the fast route entirely, so a water heater or a repipe done quietly can make the eventual legitimate permit slower rather than merely later.

We refuse every permit fee, plan review fee and inspection fee for Surprise. The fee schedule was not among the pages read, fees move on their own annual cycle, and a stale fee is worse than no fee. Community Development answers on 623.222.3000 at 16000 N Civic Center Plaza.

In Order

What to do when something goes wrong in Surprise

  1. Find out who your water provider is before you need to know.

    The City operates the water system for its own customers and there are ten other providers across the special planning areas. Use the My Surprise Address lookup once and write the answer somewhere you will find it. Your water provider, your wastewater provider and your billing contact may not be the same organisation.

  2. Read the meter, not the bill.

    Because roughly 74 per cent of a normal Surprise water and sewer bill is fixed charge by our arithmetic, a bill is a slow and blunt leak detector. A meter reading taken with every fixture shut off is a fast one. Advanced meters are being deployed across the City, which makes consumption data easier to get, but a still meter that is not still remains the cheapest test there is.

  3. Work out which band you are in.

    The difference between a leak that keeps you under 10,000 gallons and one that pushes you over 30,000 is the difference between $2.61 and $7.19 per thousand gallons. If you are already a high use household, the same leak costs you nearly three times what it costs your neighbour.

  4. Report a sewer problem to the right authority.

    For sanitary sewer overflows or odours on the City system, Water Services is on 623.222.7000. If your address has no wastewater service provider you are on site, and Maricopa County Environmental Services runs that programme on 602.506.6616. The City emergency number is 623.222.4000.

  5. Do not skip the backflow paperwork.

    If a meter has just been set, the device has to be tested and the report filed within 48 hours. Annual testing after that is the owner obligation, and a replaced device needs a fresh certification. Questions go to backflow@surpriseaz.gov or 623.222.6000.

  6. Check the grant before you commission non urgent work.

    The Plumbing Support Grant is on hold at the time of writing, but it is income tested rather than discretionary and it is worth up to $1,500. If the hold has lifted and you qualify, email conservewater@surpriseaz.gov before the work rather than after it.

Straight Answers

Plumbing questions people in Surprise actually ask

Answered from the City of Surprise published rates, codes and programme documents, with the gaps left visible rather than filled in.

Surprise operates under the 2024 International Residential Code and the 2024 International Plumbing Code, adopted 2 December 2025 by Ordinance 2025-14 and effective 1 January 2026, and local amendments are on file at the City Clerk office. We have not read those amendments and we are not going to state a permit threshold we have not verified. Ask Community Development on 623.222.3000 before the work. One thing is published and worth knowing: any project where construction has already taken place without the benefit of a permit is excluded from the self certification route, so doing it quietly makes the paperwork slower, not faster.

Look at which band the extra gallons fell into. Water is billed at $2.61 per thousand gallons for the first 10,000, $5.16 for the next 10,000, $6.00 for the next 10,000 and $7.19 above 30,000 in the year to 30 June 2027. A household that normally sits at the bottom of the first band and drifts into the second is paying roughly double per gallon for the overage. Your sewer charge, if you are on the City system, is flat at $28.69 for a single family home and will not have moved at all.

Not if you are a single family residential customer of the City wastewater system. The adopted schedule sets residential wastewater as a base charge with no volumetric column: $28.69 a month for single family, $25.20 per unit for multi family and $14.44 per space for an RV resort in the year to 30 June 2027. Commercial customers are the opposite and pay a volumetric rate that varies by business type, from $2.55 per thousand gallons for a carwash up to $7.50 for a funeral home.

You have to look it up, and it genuinely varies street by street. The City states that it operates the water system and billing for its own water, sewer and sanitation customers and that there are ten additional water service providers in the City special planning areas. Use the My Surprise Address lookup on the City website. Some addresses also have no wastewater service provider at all and are on site systems, which Maricopa County Environmental Services handles on 602.506.6616.

We do not know and we will not guess. No City of Surprise page read for this build published a hardness figure in grains per gallon or milligrams per litre. Because much of the city is served by one of ten other providers rather than by the City, a single citywide number may not even be the right shape of answer. Ask whichever utility actually bills you, and read the drinking water quality report that provider publishes.

The City publishes a dedicated arsenic page, states that arsenic occurs naturally and is not unusual in Arizona water supplies, and states that water from city owned facilities does not pose an unreasonable risk to public health as determined by the EPA. It also describes the coagulation and filtration treatment facilities built to bring levels under the 10 parts per billion federal standard set in 2001. That page has not been updated in a long time, as its reference to August 2009 shows, so read the current water quality report from your own provider for present figures.

There is a Plumbing Support Grant run by Water Resource Management worth up to $1,500 of approved indoor plumbing or outdoor irrigation repair for income qualifying households, covering dripping faucets, running toilets, irrigation leaks and unexplained high water bills. At the time of writing the City page states that all funds have been dispersed and applications are on hold pending programme updates. Email conservewater@surpriseaz.gov or call 623.222.7159 to find out whether that has changed.

Within 48 hours of the City setting the meter, and the report has to reach Environmental within 48 hours as well. After that a test is required at least once a year, and again after any repair. If the device is replaced, a new certification is required and the old device details go in the comments section of the form. Testing must be done by an approved and certified tester using a current certified and calibrated gauge, and it is the owner responsibility to make sure it happens.

Sources, arithmetic and what we refused to state

Every water, wastewater, solid waste and stormwater rate quoted on this page comes from the City of Surprise Adopted FY25 to FY29 Utility Rates Schedule, effective 1 July 2024, published from the City Utility Rates Information page. The figures used throughout are the columns for 1 July 2026 to 30 June 2027 and, where a comparison is drawn, 1 July 2025 to 30 June 2026.

The commercial wastewater rates by business type, the strength based calculation for non listed non residential customers with BOD and TSS above 150 parts per million, the Circle City base charge schedule, the non potable rate and its 1989 Effluent Reuse Agreement reference, the annual prepay figures and the stormwater equivalent dwelling unit definitions all come from the same adopted schedule.

The statement that the City operates the water system and billing for its own utilities, that there are ten additional water service providers in the City special planning areas, and the three listed water sources of groundwater, reclaimed water and Colorado River water through the Central Arizona Project, together with the statement that Surprise currently relies solely on groundwater for drinking water purposes, come from the City Drinking Water page.

The arsenic material, including the 2001 change of the federal standard from 0.050 to 0.010 milligrams per litre, the coagulation and filtration treatment description, the Desert Oasis Public Water System PWS 07-523 and Mountain Vista Public Water System PWS 07-500 identifiers and the August 2009 reference, comes from the City Arsenic in Drinking Water page. That page is undated and its content is clearly old, which is stated in the copy above rather than glossed over.

The wastewater ownership statement, the referral of areas without a wastewater provider to the Maricopa County Environmental Services On Site Wastewater Program, and the fats, oils, grease, wipes and pills guidance come from the City Wastewater page. The four treatment plants, and the SPA-3 figures of 3,192 customers, 86.12 square miles, 290,000 gallons a day average against a 1.8 million gallon design, plus the Sequencing Batch Reactor description, come from the City 2024 Annual Wastewater Report.

The 48 hour testing and reporting deadline after a meter is set, the annual testing requirement, the certified tester and calibrated gauge conditions, the owner responsibility wording and the replacement certification rule come from the City Backflow Prevention Owner Information page and the Cross-Connection and Backflow page.

The adopted code list, the 2 December 2025 adoption date, Ordinance 2025-14 and the 1 January 2026 effective date come from the City Currently Adopted Building Codes page. The self certification eligibility condition requiring certification with the City of Phoenix, the five business day issuance, the elimination of plan review fees and the full not eligible list come from the City Self-Certification Building Permit Program page.

The Plumbing Support Grant material, including the $1,500 ceiling, the four qualifying issue types, the Area Median Income table labelled by the City as 2022-23 guidelines, the first come first served wording and the current notice that all funds have been dispersed and applications are on hold, comes from the City Plumbing Support Grant page.

The arithmetic on this page is ours and is labelled as ours in the copy as well as here. That the top water band is about 2.75 times the first band is our division. That roughly 74 per cent of a normal water and sewer bill is fixed charge is our division of the $60.46 of base charges by an $81.34 bill at 8,000 gallons.

The 38,000 gallon leak scenario, its $195.22 volumetric figure, its $226.99 water total and the $174.34 increase are our multiplication of the City adopted table. That a restaurant in the top band pays $14.37 for a wasted thousand gallons is our addition of the $7.18 commercial sewer rate to the $7.19 top water band. That establishing service at $63.00 and $42.00 represents three services and two at $21.00 each is arithmetic on the City own per service wording.

The figure of 1,000 gallons a day for a continuously running toilet is a working assumption of ours and is labelled as such in the copy. No City of Surprise page read for this build published a gallons per day figure for a running toilet.

Refused and left blank rather than estimated: water hardness in any unit, because no City page read published it and much of the city is served by other providers; every drinking water constituent value and every current arsenic result; the lead and copper service line inventory; the capacity of any treatment plant other than SPA-3; every permit, plan review and inspection fee.

Also refused: the identities of the ten additional water providers, because the City publishes them through an address lookup rather than as a list; the reason the Circle City base charge is being phased; the reason a delinquent notice fee is doubled for third party water accounts; the rationale behind the ordering of the commercial wastewater tariff; and which businesses fall into the strength based calculation in practice.

No office, address, crew, response time, guarantee or coverage claim of ours is stated for Surprise, and no testimonial or performance statistic appears anywhere above. We are not a party to the Plumbing Support Grant and are not on any City list. Rates, ordinances and programmes change, and the City reviews utility rates on a five year cycle with annual steps beginning 1 July, so confirm current requirements with the City of Surprise before relying on anything here.
