Setting water rates

The vote boards most want to avoid

Of every decision a board makes, raising rates is the one members dread. You serve your neighbors. Nobody runs for a water board to charge their friends more. So boards do the kind-seeming thing and hold rates flat for years.

It is the opposite of kind. Flat rates do not make water cheaper to produce. The pumping, the treating, the testing, and the slow replacement of buried pipe all cost more every year. Holding the rate down just pushes the bill onto the next board, the next operator, and the customers who can least afford the jump when it finally lands.

So do not take pride in low rates. Take pride in rates that deliver safe, reliable water to the people you serve now and the people who will sit on this board in twenty years. That is the job. That is how a board should think about it: what a rate pays for, how the number gets built, what to fix before you raise a dime, how to protect the households that truly cannot pay, and how to bring the town along. Sewer rates work the same way, so read "water" here as water or sewer.

One thing to check first: who actually sets your rates. Most small systems set their own, by a board vote, and this guide is written for them. Some systems, mostly investor-owned utilities and certain districts, are regulated by a state public service or utility commission and have to file a formal rate case instead. If that is you, the commission's process governs, and your state page points to it.

What a rate actually pays for

A rate is not too high or too low in the abstract. It is enough, or not enough, to cover the real cost of service. That cost has three parts, and a healthy rate covers all three:

• Running the system day to day, in compliance: the operator, power, chemicals, testing, repairs, billing, insurance.
• Replacing the system as it wears out: the pump that fails, the meters that slow down, the main that has been in the ground since the 1970s.
• Setting money aside: reserves for the emergency you cannot predict and the year revenue comes in light.

Here is the trap. If a rate covers only the first part, the system looks fine on paper. The lights stay on, the bills get paid, the budget balances. Meanwhile the pipe ages and nothing is set aside to replace it. The system is quietly going broke while the books look healthy. Charging for all three parts has a name, full-cost pricing, and it is the one idea behind every sound rate.

Two things boards routinely miss. First, the hidden costs. A share of the clerk's time, a share of the board's own meeting and election expense, office costs, insurance, the accountant and the attorney, even the mowing around the well house. If the water system benefits from it, a fair share belongs in the water budget, or the rate is too low and no one notices. Second, the wall. Water revenue funds the water system, full stop. It does not plug a hole in the general fund or cover the park budget. Keep water money with water, and keep sewer, stormwater, and trash on their own books too.

Why your rates are higher than the big city

A board hears this constantly. Why do we pay more than the city down the road? The honest answer is not bad management, it is arithmetic. A small system runs the same kind of plant and meets the same rules as a big one, but it spreads that cost over far fewer customers. It often has more pipe per customer, because a rural layout runs more main to reach each home. And many fixed costs come per system, not per customer, so a 200-connection district can pay nearly as much for its annual audit and its insurance as a town ten times its size. Fewer customers carrying similar fixed costs means a higher bill each. That is worth saying plainly to your community, because it turns a high rate from a failure into a fact of small-system life.

The three tests of a good rate

A good rate passes three tests at once.

Sufficient. It brings in enough to cover all three parts of the cost, this year and across the next several. A rate that only works as long as nothing breaks is not sufficient.

Predictable. It moves in small, regular steps customers can plan for, not big surprise jumps. Most household incomes rise a little each year. The water bill should behave the same way.

Affordable. It does not price basic, health-and-sanitation water out of reach for households that struggle. Affordable is not the same as low. The right way to protect a struggling household is a targeted tool, not a low rate for the whole town. More on that below.

Hold all three at once and you have a rate you can defend at the podium and live with for years.

The two parts of a rate, and what each covers

You do not build the rate yourself. An operator, a hired consultant, or a free state program runs the study and brings you the numbers. But you approve them, and you have to explain them, so understand the shape.

Most rates have two parts:

• A base charge, billed every period no matter how much water a customer uses. Think of it as the cost of being connected and ready. It covers the costs you pay even when nobody turns on a tap: debt, reserves, billing, a big share of the operator's salary.
• A volumetric charge, billed per thousand gallons. It covers the costs that rise and fall with use: power to pump, chemicals to treat, wear on the equipment.

One simple test sorts any cost into the right part. If you would still pay it with every tap in town shut off, it is a fixed cost and belongs in the base charge. If it only happens because water is moving, it is variable and belongs in the volumetric charge.

When you raise rates, you can lift the base charge, the volumetric charge, or both. That choice is not just math, it is who pays. A high base charge falls hardest on customers who use very little, because they owe it no matter what. A high volumetric charge falls hardest on heavy users, the big households and the businesses. Neither is wrong. It is a fairness decision the board makes on purpose, with reasons you can say out loud.

One more reason the base charge matters. Water use keeps drifting down as fixtures get more efficient, but your fixed costs do not drift down with it. A system that leans too hard on the volumetric charge watches its revenue swing with the weather and the trend while its bills stay flat. A steady base charge keeps the lights on in a dry year or a slow one.

The shapes a rate can take

Beyond the base-and-volumetric split, a board picks a rate structure. For a small system, keep it simple: one to three customer classes and a block or two. The common shapes:

A flat fee. Everyone pays the same amount no matter how much they use. It only works on a system with no meters. It is cheap to run and easy to understand, but it sends no signal to fix a leak, and somebody always pays too much or too little. If you are flat and unmetered, your first project is meters.

A uniform rate. A base charge plus one steady price per thousand gallons. This is the common starting point and the easiest to explain. Use more, pay more, in a straight line.

Decreasing blocks. The price per thousand gallons drops as a customer uses more. It favors big industrial users, and it carries a real risk: at the high end you can sell water for less than it costs to produce, with small users quietly covering the difference.

Increasing blocks. The price per thousand gallons rises as use climbs. It rewards conservation, which matters where water is tight, and it keeps basic indoor use affordable while charging a premium for the pool and the lawn. The catch: a big family under one roof can look like a heavy user and get penalized for ordinary use.

Seasonal rates. Higher prices in the peak months, lower in the off months. They fit systems with big summer irrigation swings or a seasonal population, as long as you keep a year-round base charge so winter revenue does not collapse.

One more lever: the base charge can scale with meter size. A business with a two-inch meter can pull many times the water of a household's small meter, so it is fair for it to carry a bigger share of the fixed cost. A common method ties the base charge to that capacity, so a two-inch meter rated at eight times a home's flow pays roughly eight times the home's base charge.

Charges to new customers

Two charges fall on new customers, and both are the board's to set. A deposit is refundable money you hold in case a new account does not pay its bills, returned when the customer leaves in good standing. A connection fee, also called a tap fee, is a one-time charge that is not refunded. It covers the real cost of adding the connection and buys the newcomer a fair share of the system everyone before them already paid for. Set the tap fee to actually cover what a hookup costs you. Set it too low and your existing customers quietly subsidize every new house that goes up.

How the number actually gets built

The mechanics belong to the rate study, but the logic fits on one page. Picture a small district, call it Everytown. It has 600 connections and sells about 30 million gallons of water a year. Its current rates are a $20 base charge plus $5 per thousand gallons, which brings in about $295,000 a year.

Now add up what Everytown truly needs: the cost to run the system, the payment on its loan, and a modest deposit toward the well it knows it will have to replace. Say that comes to about $355,000. The $60,000 between what it collects and what it needs is the rate increase, whether the board likes it or not. The only real choices are how to spread it and how long to phase it in.

Everytown can close the $60,000 three ways:

• Through the base charge alone. Spread across 600 customers over twelve months, that is about $8 more a month each. The base goes from $20 to about $28.
• Through the volumetric charge alone. Spread across 30 million gallons, that is about $2 more per thousand gallons. The volumetric rate goes from $5 to $7.
• Or a mix of the two, landing somewhere in between.

Watch what each does to a household using 5,000 gallons a month. Today it pays about $45. Under the base-only plan, about $53. Under the volumetric-only plan, about $55. Close to the same for the average home. But the edges move very differently. A retiree using barely 1,000 gallons pays $8 more under the base-only plan and only $2 more under the volumetric-only plan. A heavy user or a small business sees the reverse, a small bump on base-only and a steep one on volumetric-only. That swing is the fairness call the board is actually making when it picks a structure. The study will sweat the details you do not see here, like the bills that never get collected, but the shape of the decision is exactly this.

Sewer follows the same three-part logic with one twist. You cannot meter what goes down the drain, so most systems bill sewer on water use, often a customer's winter usage, when little water is going to the lawn. Big industrial dischargers may also pay a surcharge based on the strength of what they send, not just the gallons, because a heavy load costs the plant more to treat.

Why waiting is the expensive choice

Small and steady beats big and sudden, every time. A rate that creeps up one to four percent a year is one customers can plan for. A rate held flat for years and then yanked up twenty or forty percent after a crisis is rate shock, and it lands hardest on the fixed-income households you most wanted to protect.

The math is not close. EPA's own rate workbook walks a small system through it: a modest shortfall in the first year compounds to a cumulative deficit of more than $600,000 within five years, and the rate still has to rise, just later and steeper. You do not save the town money by waiting. You lose it, and you take the whole political hit at once instead of a sliver at a time.

There is a darker version of waiting. A system that runs short on cash starts paying its own bills late, which dings its credit, which forces cash-only purchases, which means deferred maintenance, which means worse service and emergency repairs and fines. Each step makes the next one more likely. The increase you avoided becomes a hole you climb out of for years.

One number to keep you honest the other direction: when the price of water rises, people use a little less. A rough rule is that a ten percent rate increase trims usage about three to four percent. So an increase never brings in quite as much as the percentage suggests. Plan conservatively, and expect to revisit rates again before long.

Collect what you are already owed first

Before you raise a single rate, recover the money the system is already losing. It is the right thing to do, and it is what lets you tell the room, honestly, that you did your homework first. The list:

• Bill everyone. No free water to the city yard, the church, the ballfield, the school, or the system's own buildings. Unbilled water is a gift the ratepayers cannot afford. Watch for theft too: illegal taps, tampered meters, water pulled from a hydrant.
• Collect what you bill. Enforce the shutoff and late-payment policy evenly. When collections are loose, the neighbors who pay on time are quietly covering the ones who do not. Aim for full collection.
• Run a water audit. The gap between water produced and water billed runs anywhere from five percent to more than half at individual systems. Old meters that under-register are a common culprit, and every lost gallon was pumped and treated at a cost. AWWA offers free water-audit software, and a state program will help you run it.
• Chase the leaks. Water that never reaches a customer is pure cost. A proactive leak program beats waiting for a street to erupt.
• Trim the power bill. Pumping is usually the largest cost a system can actually control. Efficient pumps, the right electric rate, and filling storage at night under time-of-use pricing all help.
• Replace tired meters. The meter is the cash register. Once it is more than about ten years old it slows down and gives water away. A meter-replacement plan pays for itself.

A board that has done all of this walks into the rate vote with credibility. You are not reaching into pockets. You closed the gaps first.

Affordability, done the right way

Affordability is real, and a board should take it seriously. Water prices have risen faster than inflation and faster than most incomes as systems catch up on decades of deferred work. That genuinely hurts households on fixed or slow-growing income.

But holding everyone's rate flat is the wrong tool for it. It starves the system, and it does nothing to find the households that actually struggle. A low rate helps the comfortable exactly as much as the strapped. The fair fix aims help where it is needed:

• A lifeline rate that keeps the first, essential block of water affordable for households that qualify.
• A customer-assistance program, often funded by small voluntary round-ups on other customers' bills, that carries a neighbor through a hard month.

For a yardstick, funding programs often look at the water bill as a share of median household income. A common comfortable range is roughly one-and-a-half to two-and-a-half percent of median household income for the bill. If yours runs well above that, treat it as a signal to hunt for costs to cut, not as a reason to defer the maintenance that keeps the water safe. And targeting help to the households that need it actually saves the utility money, through fewer delinquencies and shutoffs. When an increase has to be large because rates sat still too long, phase it in over a few years to soften the landing.

When rates alone cannot close the gap

Sometimes the hole is too deep for rates to fill. The federal guides draw a rough line: if the full annual cost of running your system is twice or more what your current rates bring in, you cannot close that gap with customer charges alone. That is the moment to call your state drinking-water or funding agency, not to vote a rate that doubles the bill. The tools at that point:

• Borrow to spread a big capital project across the years that will use it, rather than charging today's customers for all of it at once.
• Look at working with a neighbor. Sharing an operator, buying chemicals together, or in some cases joining systems can spread fixed costs across more customers. It is not always the answer, but it is worth the look when a system cannot reach safe, compliant operation on its own.
• Lean on the free help. Your state rural water association, a university finance center, and the regional technical-assistance networks will help you build a defensible rate and chase funding, at no charge.

Bringing your community along

Do not hide a rate increase, and do not apologize for one the numbers justify. An explanation after the fact sounds like an excuse, and you forfeit support you could have had. Make the case before the vote.

Start with your own board. If the board has not walked the whole system in the last six months, schedule a tour with the operator. See the well, the tank, the plant. Sort what you find into cosmetic problems, like peeling paint, and functional ones, like a pump on its last legs. Know exactly what the increase will buy. You have done your homework when you can answer, in plain words, why we need this and what the money will do.

Then make the case to customers on three points:

• It protects health and keeps the system in compliance with the state. Safe, dependable water is not free, and the rules that keep it safe only get more demanding.
• It is built on real numbers and it is fair. Stress that the rate came from an honest look at actual costs and revenues, not a figure pulled from the air. If a neutral expert built it, say so.
• It covers the true cost of safe, reliable water. The system has to stand on its own income, and you owe customers a straight account of what that takes.

Use the channel customers actually read, the bill insert. Add the website, a word at the meeting, the local paper, even sending a note home with schoolkids. And here is the part boards forget: in a year when the numbers are healthy and no increase is needed, tell customers that too. Nobody thanks you for low rates if the water turns unsafe, but a board that is straight about the money in good years and bad earns the benefit of the doubt in the hard ones.

Questions worth asking before a rate vote

When a rate is on the agenda, take these into the room:

• Does this cover all three parts, replacement and reserves included, or just this year's operating bills?
• What did we do to cut costs and collect what we are owed before asking for more?
• What does this do to a typical bill, and to our very lowest and very highest users?
• Do we have a lifeline or assistance option for households that cannot absorb it?
• How does our bill compare to the share of local income that counts as affordable?
• If we approve nothing tonight, what does the system look like in five years?

A board's rate calendar

Rates are not a once-a-decade emergency. Look at them every year, as part of the budget. Six plain questions tell you whether it is time to adjust:

• Did revenue beat expenses in each of the last three years?
• Did we make every scheduled debt payment?
• Are we funding our reserves on purpose, not by accident?
• Did we cover emergency and preventive maintenance without scrambling?
• Are we in compliance with the state?
• Have we raised rates in the last three years?

A "no" on any of these is a flag. The honest way to answer them is a short financial forecast, three to five years out, which the operator, a consultant, or a free state program can build with you.

The deep mechanics, the worksheets and the multi-year forecast, are a job a board oversees rather than runs. Who sets your rates, and who in your state will help you build the case at no charge, lives on your state's page. Reserves have their own guide, and the wider shape of the job sits on the board hub.
