Plumber Folsom: The City That Prices Sewer By Counting Furniture
Most cities decide your sewer charge by looking at how much water went through the meter. Folsom does something else. A house here pays a flat monthly fixed charge for wastewater collection, with no volume element at all, and a business pays according to how many of a countable thing it has: chairs, lanes, beds, bays, rooms, pumps, machines, fixtures.
That single design decision changes which of your bills a plumbing fault actually reaches, and it is the opposite of how the rules work in other California cities we have written up. This page sets out the published rates, the published system figures, the permit clocks and the identification details the City puts on the record. Everything comes from City pages. Where the arithmetic is ours, the sentence says so.
Why a plumber Folsom businesses call is answering a different question
Read the non-residential wastewater table and the logic jumps out. A salon is billed 2 dollars 54 cents per chair. A bowling alley pays 10 dollars 17 cents per lane. A hotel or motel pays 10 dollars 17 cents per room, a service station 2 dollars 54 cents per pump, a self serve laundry 12 dollars 72 cents per machine, a garage 2 dollars 54 cents per bay, a rest home 10 dollars 17 cents per bed and a mortuary 45 dollars 78 cents per slumber room.
Two entries in that table are worth a plumber reading twice. Mini storage is billed at 26 dollars 45 cents per fixture, which makes a fixture count a rate decision and not only a design decision. And theatres are billed per 100 seats while schools are billed per 100 students, so the unit of service is occupancy rather than plumbing at all.
Floor area classes exist too, and the spread inside them is wide. A park is 1 dollar 2 cents per 1,000 square feet and a retail store 2 dollars 54 cents, while a dining room restaurant is 129 dollars 71 cents for the same 1,000 square feet. That is roughly 25 times the office rate of 5 dollars 9 cents, and that comparison is our division of two published numbers rather than a City statement.
Only two classes on the whole non-residential list are billed on measured water: metered automatic car washes and hospitals, at 1 dollar 4135 per hundred cubic feet. Colleges get the single winter average in the schedule, at 27 cents per 100 gallons. Everyone else is priced on a count of physical things.
What that means for a leak in a Folsom house
The residential half of the same table is short and it is the most useful sentence on this page. Residential per dwelling, manufactured or mobile home per dwelling, and multi family per unit are all charged 25 dollars 43 cents as a monthly fixed charge, effective July 2022. There is no consumption column. There is no winter average. There is no cap, because there is nothing to cap.
So a running toilet in Folsom does not move your sewer bill. Neither does a slab leak, a dripping bib, a softener stuck in regeneration or a month of guests. The wastewater collection charge for a dwelling is the same number whether the house is empty or flooding, which by our multiplication is 305 dollars 16 cents over a year.
This is worth stating plainly because the opposite arrangement is common and we have documented it. In El Cajon, published on this site today, the residential sewer charge is calculated from a five month winter average of water use and then multiplied by six before landing on a property tax bill. Same state, two cities a few hours apart, and a January leak is a twelve month financial event in one of them and a non event in the other.
None of which makes a leak cheap in Folsom. It moves the cost, it does not remove it. The entire bill for a household leak here lands on the water side, and the water side is where Folsom does use volume.
The water bill is where the volume lives
Residential water is a fixed monthly base plus a tiered commodity rate. The single family base at a one inch meter is 20 dollars 9 cents, with a low income rate of 12 dollars 65 cents and a condo rate of 12 dollars 66 cents. On top of that, consumption is charged at 1 dollar 51 cents per hundred cubic feet for the first 20, 1 dollar 61 cents from 20 to 40, and 1 dollar 75 cents above 40.
Tiers are the reason a leak compounds here. Every extra hundred cubic feet a fault sends through the meter is billed at whatever tier your household has already climbed into, and the top tier runs about 16 per cent above the bottom one. That percentage is our division of two published rates, not a City figure, and it is the whole mechanism by which an undetected leak gets progressively more expensive.
Where you live inside Folsom changes the bill as well. The City lists an East Area surcharge of 4 dollars 20 a month and a Folsom Plan Area surcharge of 9 dollars 20 a month on the residential side, with equivalents of 12 cents and 85 cents per hundred cubic feet on the non residential side. Two identical houses with identical use can carry different fixed charges.
Non residential water base charges run by meter size rather than by class, from 13 dollars 39 cents at a five eighths inch meter to 2,258 dollars 99 cents at twelve inches, with all consumption at 1 dollar 55 cents per hundred cubic feet. For a business the meter you install is a long running monthly commitment, not a one off cost.
- Your sewer charge: not at all, if you are a household. The residential wastewater collection rate is a flat monthly fixed charge per dwelling with no volume element. Stop worrying about this one and put the attention on the water side.
- Your water charge: yes, and increasingly. The commodity rate is tiered, so the longer a fault runs the more expensive each additional unit becomes. This is the bill that tells you a leak exists.
- Your sewer charge, if you run a business: only if the count changed. Adding a chair, a bay, a bed, a pump, a machine or a fixture changes the rate basis. Using more water usually does not, unless you are a car wash or a hospital.
- Check the meter yourself. Folsom offers a customer portal for consumption history, so the trend is visible without waiting for a bill. A rising baseline overnight is the classic signature.
- Find your two lids before you need them. The City describes the cleanout as most often a four inch green circular lid and the backflow as a six inch green circular lid next to it. Knowing where they are saves time on the day it matters.
- Do not dig first. The City asks residents to call Underground Service Alert on 1-800-642-2444 before excavating, and that applies to a homeowner with a shovel as much as to a contractor with a machine.
- Get a second opinion on a big sewer job. This is the City position, not only ours. Its published do not list includes proceeding with an expensive sewer line repair without getting one.
Folsom publishes the detail most cities leave out
The City tells residents what to look for in their own gardens, in physical terms. A cleanout is described as most often a four inch green circular lid. A backflow device is described as a six inch green circular lid located next to the cleanout. That is a rare level of specificity from a municipal page and it is genuinely actionable.
It also gives a free method for working out where the lateral runs. Line up the city cleanout at the sidewalk with the cleanout beside the house, and the line between them is the approximate route. The City offers to help by phone if that does not resolve it, and asks residents not to plant trees directly over a sewer line because root growth causes problems.
The published do and do not lists are practical rather than promotional. Deposit cooking grease, eggshells and coffee grounds in the trash rather than down the drain or the disposal. Do not flush baby wipes or diapers. Recycle motor oil, paint and other toxic materials at the City household hazardous waste facility or through kerbside oil recycling rather than pouring them into the sewer.
Two items on that list are about who does the work. The City says to use only a licensed contractor or plumber to make repairs, and to check out an unlicensed or unknown contractor before letting them start. And it lists proceeding with an expensive sewer line repair without getting a second opinion among the things not to do. A city advising residents to get a second opinion on plumbing work is unusual enough to reproduce without softening it.
The size of what sits under the streets
Folsom publishes its system figures, and they are more complete than most cities of its size manage. The Wastewater Collection Division states that it inspects, cleans, repairs and maintains 271 miles of pipeline and eleven lift stations, serving 22,800 residential and commercial service connections, moving a daily average of 8,000,000 gallons.
It also publishes the ceiling: a maximum daily pump station capacity of 15,600,000 gallons. Put those two side by side and an average day runs at roughly 51 per cent of maximum pumping capacity, which is our division rather than a City statement. The City adds that peak usage falls early in the morning as residents get ready for work and again in the evening when they get home.
Maintenance runs on a five year cycle covering main line cleaning, closed circuit television inspection, and manhole and lateral inspections. Across 271 miles that implies something near 54 miles a year, which is again our arithmetic. The City names its top maintenance issues directly: blockages from grease, and large debris such as rocks and cans entering the pipeline.
On the water side the Water Quality Division reports 372 miles of water main and approximately 22,000 water service connections, with 14 storage tanks, six booster pump stations and approximately 3,800 fire hydrants. The water network is therefore about 101 miles longer than the sewer network on the City own figures, which is our subtraction and is stated without any claim about why.
Meters, backflow and where the responsibility sits
The Water Meter Division states that it installs, maintains and repairs approximately 25,000 residential and commercial meters ranging from five eighths of an inch to twelve inches, and operates a fixed network reading system of 19 collectors plus repeaters that collect reads from a radio attached to each meter. A programme is currently replacing approximately 3,000 aging residential meters, which the City notes does not cover every residential meter in the city.
Two practical requests come with that. Keep the meter box accessible by trimming shrubs and trees near it, and avoid planting near it in the first place, because mature branches can affect the radio signal from the fixed network endpoint and roots cause problems with the underground pipes. If a retaining wall is planned near the meter, the City asks to be contacted first.
Backflow is where responsibility shifts onto the customer, and the split is stated clearly. The Cross Connection Control programme oversees annual testing of devices to prevent backflow into the potable system. The City issues letters notifying customers when tests are due. Customers are then responsible for arranging the testing themselves, and it must be carried out by a Sacramento County Environmental Management Department certified backflow prevention assembly tester.
Where does the wastewater go? Not far, in City terms. Folsom collection flows into the Sacramento Area Sewer District interceptor sewer system and is treated at the EchoWater Resource Recovery Facility. Folsom collects and conveys; another agency treats. The City directs anyone wanting treatment and resource recovery rates to the Sacramento Area Sewer District rather than publishing them.
Three permit clocks, and two of them disagree
Folsom publishes its expiry rules in one place, and reading them together is instructive. A permit application expires 180 days after the date of filing unless the permit has been issued, and if it lapses a new application must be filed under whatever code is current at that point.
Then the permit itself carries two published lifespans. Under State law, the City states, building permits expire 12 months after issuance unless work has commenced to the satisfaction of the Building Official, or if more than 180 calendar days elapse between approved required inspections after that initial 12 month period. Per the Folsom Municipal Code, the City states, building permits expire two years after issuance. Both are printed here as published and neither is preferred, because we cannot tell from outside which governs a given permit.
The code cycle changed underneath all of this. The 2025 California Building Standards Code, Title 24, took effect on 1 January 2026, and the City explains the consequence for work already in the pipeline: an application filed before that date can stay on the 2022 cycle so long as neither the application nor the permit expires. If either expires, the project must be resubmitted under the 2025 code with updated documents, a new application and new fees.
Two operational details are worth noting for anyone planning a job around that boundary. The City began accepting submittals designed under the 2025 code on 10 November, and it accepts permit applications only through its online system. It also notes that 31 December and 1 January are City holidays, which sits directly on the changeover date.
Who to call, and what this page does not claim
The City publishes one number for water leaks and sanitary sewer problems during business hours, 916-461-6177, running 7am to 3:30pm, and a separate after hours number for water and wastewater emergencies, 916-461-6400. Water waste reports go to the same daytime number or to the City water conservation address.
On the private side of the property line the work is ordinary plumbing with an unusual price signal attached. Leak detection is what finds the fault your flat sewer charge will never reveal. Sewer line repair covers the lateral, drain cleaning covers blockages, and emergency plumbing covers out of hours.
Nearby, the rules change again. Our Sacramento, Roseville and Elk Grove pages cover their own billing and permit arrangements, and none of them matches Folsom. Sharing a county does not mean sharing a rate structure.
Plumber Folsom: the questions a flat sewer charge creates
Answers built only from what the City of Folsom publishes. Where we have done arithmetic on published figures, the sentence says so.
Not if you are a household. The City wastewater collections rate for residential per dwelling, manufactured or mobile home per dwelling and multi family per unit is a monthly fixed charge of 25 dollars 43 cents, effective July 2022, with no consumption element listed. A leak therefore cannot move it. The cost of a household leak lands entirely on the water bill instead, where the commodity rate is tiered.
By counting things rather than by measuring flow. The published non-residential table charges a salon per chair, a bowling alley per lane, a hotel per room, a garage per bay, a rest home per bed, a service station per pump, a self serve laundry per machine, a mortuary per slumber room and mini storage per fixture. Others are charged per 1,000 square feet, per 100 seats or per 100 students. Only metered automatic car washes and hospitals are billed on measured water.
On the floor area classes, a dining room restaurant at 129 dollars 71 cents per 1,000 square feet is the highest published rate, ahead of dine in and takeout combined at 106 dollars 82 cents and takeout alone at 66 dollars 12 cents. Compare that with an office at 5 dollars 9 cents for the same area and the dining room pays roughly 25 times as much, which is our division of two published figures rather than a City comparison.
On the water commodity rate, which is tiered. The residential rate is 1 dollar 51 cents per hundred cubic feet for the first 20, 1 dollar 61 cents from 20 to 40, and 1 dollar 75 cents above 40. Every extra unit a fault pushes through is billed at whatever tier you have already reached, and the top tier is about 16 per cent above the bottom one by our arithmetic. That is why an undetected leak gets progressively worse rather than costing a flat amount.
Possibly geography. The City lists an East Area surcharge of 4 dollars 20 a month and a Folsom Plan Area surcharge of 9 dollars 20 a month on residential water, with per unit equivalents of 12 cents and 85 cents on the non-residential side. It may also be meter size or class of service, since the residential base runs 20 dollars 9 cents for single family at a one inch meter, 12 dollars 65 cents for low income and 12 dollars 66 cents for a condo.
The City describes it. A cleanout is most often a four inch green circular lid, and a backflow device is a six inch green circular lid located next to it. To work out the route of the line, the City suggests lining up the city cleanout at the sidewalk with the cleanout beside the house. It offers help by phone if that does not resolve it, and asks residents not to plant trees directly over a sewer line because root growth causes problems.
You are, once you have been told. The City Cross Connection Control programme oversees annual testing and the City issues letters notifying customers when tests are due, but customers are then responsible for making the arrangements. The test must be completed by a Sacramento County Environmental Management Department certified backflow prevention assembly tester, and test reports are submitted electronically through the City testing portal.
The City publishes two answers and this page does not choose between them. It states that under State law building permits expire 12 months after issuance unless work has commenced to the satisfaction of the Building Official, or if more than 180 calendar days elapse between approved required inspections after that initial period. It also states that per the Folsom Municipal Code building permits expire two years after issuance. Separately, a permit application expires 180 days after filing if no permit has issued.
The 2025 California Building Standards Code, Title 24, took effect. The City states that an application submitted before that date can remain on the 2022 code cycle so long as neither the application nor the permit expires, and that if either expires the project must be resubmitted under the 2025 cycle with updated documents, a new application and new fees. It began accepting 2025-code submittals on 10 November and accepts applications only through its online system.
This page does not say, because no page we read states it. The City describes a broad maintenance remit covering the mains, and it describes where the cleanouts sit, but it does not publish a boundary between City and property owner responsibility for the lateral itself. Rather than infer one, we leave it unstated. Confirm it with the Wastewater Collection Division on 916-461-6177 before assuming who pays for a repair.

Every rate quoted above, residential and non-residential, water and wastewater, including the flat residential wastewater charge of 25 dollars 43 cents per dwelling, the full non-residential unit of service table from salon chairs through bowling lanes, hotel rooms, garage bays, fuel pumps, laundry machines, rest home beds, mortuary slumber rooms, mini storage fixtures, theatre seats and school students, the tiered residential water commodity rates, the non-residential base charges by meter size, and the East Area and Folsom Plan Area surcharges, comes from the City of Folsom Utility Rates page, effective July 2022.
The 271 miles of pipeline, eleven lift stations, 22,800 service connections, 8,000,000 gallon daily average, 15,600,000 gallon maximum daily pump station capacity, the morning and evening peak pattern, the five year preventative maintenance programme of main line cleaning with closed circuit television, manhole and lateral inspection, the discharge to the Sacramento Area Sewer District interceptor and treatment at the EchoWater Resource Recovery Facility all come from the City of Folsom Wastewater and Sewer page.
That same page is the source for the description of the cleanout as a four inch green circular lid and the backflow as a six inch green circular lid beside it, the method of lining up the two cleanouts to find the run, the Underground Service Alert number, the do and do not lists, and the advice not to proceed with an expensive sewer line repair without getting a second opinion. It is the City of Folsom Wastewater and Sewer page.
The 372 miles of water main, approximately 22,000 water service connections, 14 storage tanks, six booster pump stations, approximately 3,800 fire hydrants, and the Cross Connection Control arrangement under which the City issues notification letters while customers are responsible for arranging testing by a Sacramento County certified backflow prevention assembly tester, come from the City Water Quality Division page. The approximately 25,000 meters from five eighths to twelve inches, the fixed network system of 19 collectors and repeaters, the replacement programme covering approximately 3,000 aging residential meters, the customer consumption portal and the meter box access requests come from the City Water Meter Division page.
The permit application expiry of 180 days, both published permit lifespans (12 months under State law with the 180 day inspection gap rule, and two years per the Folsom Municipal Code) and the 2025 California Building Standards Code taking effect on 1 January 2026 all come from the City of Folsom Building Services page.
That same page is the source for the treatment of applications already filed under the 2022 cycle, the requirement to resubmit with new documents and new fees if an application or permit expires, the 10 November start for 2025-code submittals, the online-only application route, and the note that 31 December and 1 January are City holidays. THE TWO PERMIT LIFESPANS ARE PRINTED AS PUBLISHED AND NEITHER IS PREFERRED, because we cannot determine from outside which governs a given permit.
Four figures above are ours and are labelled as ours in the copy as well as here. That an average day runs at roughly 51 per cent of the published maximum pumping capacity is our division of 8,000,000 by 15,600,000. That a five year cycle over 271 miles implies near 54 miles a year is our division. That the water network is about 101 miles longer than the sewer network is our subtraction of 271 from 372.
The same applies to the rate comparisons. That the top water tier is about 16 per cent above the bottom is our division of 1 dollar 75 cents by 1 dollar 51 cents, and that a dining room restaurant pays roughly 25 times the office rate for the same floor area is our division of 129 dollars 71 cents by 5 dollars 9 cents. The annual residential wastewater total of 305 dollars 16 cents is our multiplication of the published monthly charge by twelve. None of these figures appears on any City page.
Refused and left blank rather than estimated: water hardness and every drinking water quality value, because the City Water Quality Division page describes monitoring and the backflow programme without publishing constituent figures and the annual report documents were not opened; all building permit, plan check and inspection fees, because the fee pages were identified and not opened; and the Fats Oils and Grease ordinance section numbers and every grease interceptor sizing requirement, because that page is a list of linked documents and none was opened.
Also refused: the Sewer System Management Plan contents; any sanitary sewer overflow count; the mileage inspected to date under the five year programme; the EchoWater facility capacity; and the Sacramento Area Sewer District treatment rates, which the City directs readers elsewhere for rather than publishing.
No boundary between City and property owner responsibility for the sewer lateral is asserted anywhere above, because no page we read states one. No office, address, crew, response time, guarantee or coverage claim of ours is stated for Folsom, and no testimonial or performance statistic appears anywhere on this page. Rates, code cycles and programmes change. Confirm current requirements with the City of Folsom Environmental and Water Resources Department or Building Services before relying on anything here.
