Frequently Asked Questions

Why did my bill increase?

An unusually high water bill is most often caused by a leak or change in water use. Some common causes of high water bills include:

  • A leaking toilet, or a toilet that continues to run after being flushed
  • A dripping faucet; a faucet drip can waste 20 gallons of water, or more, a day
  • Filling or topping off a swimming pool
  • Watering the lawn, new grass, or trees; also check for a leaking or turned on outside spigot
  • Kids home for summer vacations or school holidays
  • Guests or additional family visiting
  • Water-cooled air conditioners
  • A broken water pipe or obvious leak; check the pipes in the basement or crawlspace; the water heater could also be leaking
  • Water softener problems – cycles continuously
  • Running the water to avoid freezing water pipes during cold weather

Learning how to save water at home is very important because a typical family of four uses 40‐50 gallons of water per person per day, 160–200 gallons a day, and 4800–6000 gallons per month. The largest water users are the toilets, clothes washer and showers, which account for about two‐thirds of the water used in an average household. Toilets use up to 27% of the household water supply, while clothes washers use approximately 20%, and showers use approximately 17%. Faucets account for about 15% and leaks account for 13% of a family’s water use. Dishwashers, baths, and other uses account for the remaining water use. Generally, water consumption is higher during the summer due to watering of lawns, pools, and gardening.

I made a payment on DOXO. Will I be cut off?


While Doxo is a legitimate third-party bill payment system, CMD does not endorse it, nor do we encourage our customers to use it. Based on our experience, we know that Doxo will make your payment for you. However, that payment can be delayed as much as 14 days, which may result in disconnection of your service.

When you make a payment through Doxo or any other third-party payment system, You are paying that company, not CMD. That company, in turn, will mail a check to CMD, which takes time. We all know the mail isn’t the fastest way to get things done these days, so while we’re waiting for your payment, you might run out of time. Unfortunately, there is nothing CMD can do to stop disconnection if your payment is made through Doxo and does not arrive in time.

In other words, if you’re facing disconnection, don’t use this service. Call our IVR system at (833) 209-4044 to make your payment instantly. 

Or, if you want to make your payment online, we urge you to visit our Bill Payment Host, Municipal Online Payments is the only authorized online bill payment system for CMD. Payments made here are immediately posted to your account and you are emailed both a receipt and a confirmation number in case you ever have a question about your payment.

What are all those charges on my bill?

Water Base — This is the minimum water charge for any customer.

Water Consumption — This is the charge for your water usage. CMD Bills in 1,000 gallon increments.

Sewer Base — This is the minimum sewer charge for any customer

Sewer Consumption — This is the charge for your sewer usage. It is based on water usage.

Garbage — This is the amount of money your municipality charges for Garbage Service.

I might have a leak! What do I do?

If you think you have a leak, your first step is to call the CMD office at (803) 385-5123. You will need to provide your name and the physical address of your property. Our staff will send a worker out to check your water meter. Please make sure all toilets, sinks, bathtubs and outside faucets are off. Once our personnel visit, you will be notified of the findings.

Sometimes customers may have leaks that CMD personnel cannot locate. These leaks may appear in the form of leaking toilets. They don’t always run, but when they do they can be costly.

If you believe your toilet may be leaking, one method of detection is to pour a packet of powdered drink mix into your toilet’s tank. If the toilet is leaking, the colored water will leak into your toilet bowl.

If you do have a leak, you will need to contact a plumber to have the leak repaired. Be sure to get a receipt, because under some circumstances CMD can offer an adjustment after the leak has been repaired.

Sometimes our customers find that a water hose has been left running for an extended period of time. A standard water hose can run approximately 10 gallons per minute which means that in less than two hours, that running hose can spill enough water to raise your bill. It takes 1 hour and 40 minutes to spill 1,000 gallons of water, and every 1,000 gallons of water wasted means another $7-$16 added to your bill.

Unfortunately because this is a human error, CMD cannot offer an adjustment on a high bill due to a running water hose.

Can I turn my water off myself?

Every customer service has a Customer Cutoff Valve installed in the service line. This is a round, green box located between your meter and your house. Sometimes they are hard to find, especially if your grass is thick, or you haven’t used it in awhile. It will look similar to this:

 The lid on this box is not locked. Inside the box is a valve that the customer can turn on and off. If you have trouble locating or turning this valve, or you find that the valve is broken, please contact the CMD Office at (803) 385-5123 so our maintenance staff can assist you.

Why did you raise rates? They're already too high!

The only money the CMD receives comes from customer payments. The District does not receive tax money to help offset daily operations costs. We raise our rates for a number of reasons—increases in chemical costs used to treat the water, increases in the cost of repair materials, and the rising cost of general operation to name a few. CMD makes great effort to secure grant funds for system upgrades and replacement, which helps improve service for customers as well as keeping the rates as low as possible. The less money we have to spend, the less cost we have to pass on to our customers.

CMD’s rates recently changed, which resulted in a decrease in cost to many of its water customers. However, CMD also bills for services other than water, which often makes the bill appear much higher. 

The average customer in Chester 4,000 gallons of water or less per month. Many of our customers use less than 2,000 gallons per month. If you divide the associated water charge of $46.11 for 4,000 gallons, the charge per gallon is only a penny.

Other utilities let me change my billing date. Why won't you?

CMD bills in six cycles, which are determined by our meter reading routes. This is the simplest and most cost-effective method of reading the 6,200+ meters in our system. By allowing a change in billing dates, CMD staff would be required to duplicate effort, which would slow down the billing process, resulting in late billing.

However, as our system evolves and new technology becomes available, this policy may change. Because many of our customers have asked for the ability to change bill dates, we are researching this option.

Why is that hydrant running? Am I paying for that water?

CMD personnel flow hydrants for many reasons. Typically when a hydrant is running while unattended, it is to flush the line that feeds the hydrant. This can be due to a low residual disinfectant reading on a dead-end line, a reported water quality issue, a line break, or regularly-scheduled preventative maintenance. Water flushed from public hydrants is NEVER included on a customer’s bill.

Where does my water come from? How is it treated?

CMD gets its water from the Catawba River as it comes through Fort Lawn. It goes through an extensive disinfection and treatment process at our water treatment facility. The water is disinfected by using a compound called “Chloramines”, which are made of chlorine and ammonia. This compound provides better, longer-lasting disinfection with less chlorine taste and smell. The water is then pumped throughout the CMD system and often stored in one of our above-ground storage tanks.

When is my bill due? When will it be turned off?

Our billing runs in six cycles throughout the month. Each cycle is billed at approximately the same time each month. No matter which cycle your bill falls in, it is always due fifteen days after the date on the bill. If your bill is not paid within that first fifteen days, a late fee is added to it.

If the bill is still not paid ten days after your due date, your account is assessed a non-payment fee and scheduled for disconnection. If your service is disconnected, you must pay the entire outstanding balance on your account for service to be restored. Should you decide to have your service reconnected after hours, there will be an additional fee added to your total due.

In short: if your bill goes unpaid, you can expect your water to be disconnected 25 days from the “Bill Date” on the top of your bill.

I need to turn on, turn off, or transfer service. What do I do?

Your first step is to call the CMD office. When you speak with the customer service staff, they will tell you what information we require. Most often we need a photo ID (driver’s license or state-issued ID card) and proof of residence (rent receipt, rental agreement, landlord’s letter, or copy of the deed).  We ask for these documents as a safety precaution for you—we don’t want to turn your service off because someone else tells us you said it’s okay.

If you are transferring your service to another location or disconnecting service completely, please contact our office. We are not able to take those requests online at the present time.

What are those ads I keep seeing in the newspaper?

CMD occasionally runs advertisements in the newspaper. The most common are for the Chlorine/Ammonia Burnout and Hydrant Flow Testing programs, or for Commission Meetings. Any article CMD runs in the newspaper is something we consider “important information” that we want all of our customers to know.

The Chlorine Burnout procedure is a method for disinfecting our water system. Instead of running chloramines, CMD turns off the Ammonia feed and uses chlorine alone to disinfect the lines. Once the system has been flushed, chloramines are reintroduced to the system. Aside from a stronger chlorine-smell, it typically has no impact on customers.

The Flow Testing procedure still requires CMD staff to flow hydrants, but instead of disinfecting the system, we test each hydrant in the district for flow and pressure readings. This helps ensure that the fire system is in proper working order, and helps flush the lines for disinfection purposes at the same time.

I got an advertisement for water line insurance in the mail. What is it?

Advertisements of that nature are sometimes considered to be a scam. Companies send out these notices hoping to convince customers that their water lines are in danger. It might come to you with CMD’s name on it, but we didn’t send it. Paper correspondence from CMD will come in two forms—with your water bill, or as a letter on district letterhead.

As for the repairs, if a water line breaks on CMD’s side of the meter, we will repair it at no cost to you. But if it breaks on your side, you will have to have a plumber repair it. Hold onto your receipt! Your repairs may qualify you for an adjustment to your bill.

Why do you charge payment processing fees?

A “processing fee” is a per-transaction cost of using a specific service. In our case, the service provided is debit/credit transactions.

While CMD is able to process cash, check, and money-order payments in the lobby free of charge, we are subject to various fees when accepting credit, debit, and e-check payments. These fees are not unique to CMD; they are charged to any business whose payments are processed by third-party companies.

Generally, retail and for-profit businesses are able to absorb these fees in the cost of the products they sell. Being a utility, CMD is not able to absorb these fees as a “cost of business”. Rather than raise rates to cover the processing fee, CMD has chosen to charge the fee only to those who use the service.
