Our nation’s biggest tragedy has resulted in an increased safety awareness of the various infrastructures upon which we rely every day. Our mission has always been to supply safe, clean water to our customers. In doing so, we take security very seriously. We have a strong foundation of ongoing safety measures at WSSC: security at our facilities; round-the-clock monitoring of our distribution system; state-of-the-art security technology for our computer and operations systems; and extensive water quality testing of our water from source to tap.
Please be assured we are taking all appropriate steps to safeguard your water. Since 911, security has increased at all our facilities and our officers are on the highest alert, 24-hours-a-day, seven days a week. We also are closely coordinating with local and federal authorities.
You can help too. If you observe what you believe to be unusual behavior near any of our facilities, do not attempt to approach the subject(s). Please take note of as much information as is safely possible, such as the location, number of people and their descriptions, and the unusual activity. Then call 911 right away to report the information.
Please refer to the Household Water Usage Chart.
Prior to calling WSSC, please check the property’s main shut off valve to ensure it has not been accidentally turned off. If you main shut off valve is fully open and you do not have a past due balance, please contact an agent at 301-206-4001 or 1-800-828-6439. A telephone call, in most cases, will be handled quicker than an email request. WSSC must receive a completed Release of Liability (ROL) prior to restoring service.
If your account is past due, you will need to pay the delinquent balance and any fees in full prior to WSSC restoring your service.
Please refer to the Meter Testing page.

Residential and some commercial customers using less than 5,000 gallons a day can expect to receive a bill from WSSC approximately every three months. Our commercial customers with an Average Daily Consumption (ADC) of 5,000 gallons or more per day receive a bill approximately every 30 days.
Depending on the date you moved into the property as well as our meter reading schedule, your first bill may contain charges for only a portion of the initial three-month period you occupied the premises. Then bills will be mailed quarterly.
Pipeline is an informational publication included with each bill that provides public hearing dates, conservation techniques, policies for adjusting accounts, and other topics of interest.
WSSC now offers Electronic Paperless Billing, learn more about Go Green.
Please refer to the Payment Options page.
Your billed charges are based on the amount of water that passed through the meter since the last billing period. Sewer; however, is not metered and charges are based solely on water consumption.
Your overall consumption is then divided by the number of days in the billing period to come up with the “average daily consumption.” The higher the ADC, the higher the cost per thousand gallons. Our incremental rate structure is designed to encourage and reward water conservation.
“Comparable” consumption is what was consumed during the same time period in the previous year. If there has been a dramatic increase based on your comparable consumption, we will alert you in the important message section of the bill.
WSSC charges more for sewer service because wastewater treatment is more expensive and complicated than water filtration. Each bill also includes an item labeled Account Maintenance Fee.
When circumstances such as inclement weather, an inaccessible or obstructed meter, or a locked gate (to name a few) prevent WSSC from obtaining an actual meter reading, our computerized billing system automatically generates an estimated bill. We will also estimate usage when there are questionable changes in current consumption compared to historical usage.
A residential customer's usage is estimated based on the household’s comparable usage. When there is a new owner/occupant at the property, the estimated bill is based on a preset Average Daily Consumption (ADC) of 245.
Commercial customers' bills are estimated based on the previous occupants' ADC.
If we are unable to obtain an actual meter reading, the field service representative will leave a card at the property requesting that you supply us with an actual reading from the inside meter and visual remote reader (located on an outside wall of the property) as soon as possible. Both the inside meter and visual remote readings contain 7-digits and should be read left to right, including any stationary zeros painted on the face of the registration unit. (Customers cannot read electronic remotes.)
To provide an actual reading during non-business hours, please access our Interactive Voice Response System at 301-206-4001. You can provide an agent with your actual meter reading Monday through Friday at 301-206-4001 or firstname.lastname@example.org.
The actual reading in almost all cases cancels the estimated charges and re-bills actual usage. We will credit your estimated bill payment when we reduce the current charges by the amount of the estimated bill payment.
Please refer to our Payment Options page.

If water is used outside (i.e., landscaping, filling pools, car washes, power washes), be prepared for a higher Average Daily Consumption (ADC) resulting in higher billed water and sewer rates. Installing a sub-meter or leasing a fire hydrant could be what you need. Without a properly installed sub-meter or a fire hydrant rental, your billed charges will be based on your water consumption and the outside water usage never returns to the public sewer for treatment.
Please refer to our Sub-Meter Information file.
Please refer to our Fire Hydrant Meter Information page.
If you have a high bill and you do not know where the water is going, you may wish to check the property for leaks, especially toilet leaks. In fact, one leaking toilet can lose as many as three to five gallons each minute, often silently! The three most common toilet leaks are: flapper, siphon tube, and overflow leaks.
We also offer property inspections to assist with your leak investigation. To schedule an inspection, please call 301-206-4001 or 1-800-634-8400. The inspection fee is minimal because our inspectors will not make repairs and toilet leaks are the leading cause of unexpectedly high bills. In many cases, a new toilet tank kit or new flapper from the hardware store will remedy a toilet leak. Toilet flappers and toilet tanks should be checked at least once a year.
Please refer to our Household Leak Detection page.
*The adjustments set forth in this section are subject to available funding in the approved annual budget.
The most commonly offered adjustment is our courtesy “High Bill Adjustment” (Single Unit Residential Properties). This adjustment applies if a “single unit” residential customer receives a bill with an average daily consumption (ADC) at least three times the comparable ADC and no other applicable adjustment policy exist.
Eligible customers may receive this adjustment on one bill once every seven years while at that property. Charges are adjusted based on comparable or current ADC plus 50% of the excess usage on the one bill.
Comparable consumption is your billed ADC from the same time period in the previous year as long there were no occupancy changes after the comparable period.
A single unit commercial property can also receive a High Bill Adjustment (Single Unit Commercial Properties); however, the higher than normal charges are re-billed based on comparable or current (if no comparable consumption is available), plus 75% of the excess usage. Unlike the residential high bill adjustment, a commercial property is limited to one high bill adjustment.

In this example, the January 12, 2012, consumption does not qualify for the HBA. The “comparable” January 1, 2011, charges were based on a 121 ADC. The 319 ADC billed January 12, 2012, is not three times the comparable (121 x 3 = 363).
However, the 392 ADC billed April 1, 2012, qualifies (if occupancy did not change and there were no leaks) since it is at least three times the comparable 98 ADC billed March 31, 2011 (98 x 3 = 294).
Call 301-206–4001, 1-800-634-8400 or email@example.com. We will thoroughly review the account to determine whether the charges qualify for adjustment according to WSSC’s policies and guidelines. If you are unhappy with our decision, you may appeal the billed charges in one of two forums.
Please refer to the Refund Hearings page.
Yes, we will assess a fee if a check is not honored, your bank does not satisfy an electronic debit, or a credit card payment is not properly authorized. Furthermore, a "cash only" status will be assigned to the account for six months. During that period, payments must be made via certified or bank check, credit or debit card, Western Union Quick Collect, or money order. Written notification that a payment has not been satisfied and that the account has been placed in "cash only" status will be mailed to the service address.
If you feel the payment was returned due to a bank error, please provide a letter from your bank that indicates the error was theirs and we are happy to reverse any adverse account action taken. Miscellaneous Fees Table
Discolored water contains an accumulation of iron and manganese sediment from rusting cast iron pipes and/or from a buildup of chemical deposits on the pipes. Water steadily flowing at an even pace in one direction will not disturb these deposits. However, if the water suddenly flows very fast or reverses direction, sediment and deposits are stirred up, resulting in discoloration.
Causes of Discolored Water:
Discolored water is generally safe to drink for healthy individuals. However, individuals with compromised immune systems (such as cancer patients undergoing treatment, HIV positive individuals, transplant recipients, seniors, and infants), should take any precautions they would normally take with regular tap water and/or seek advice from their physician before consuming discolored water.
WSSC does not recommend using discolored water to do laundry.
If clothing gets stained, immediately wash the clothes again using a rust remover product. This type of product is available in most supermarkets or you can contact WSSC at 301-206-8100, 1-800-634-8400, or firstname.lastname@example.org and request a stain remover. For better results, do not let the clothes dry.
Household uses for Discolored Water:
Discolored water can be used for showering, flushing toilets, cleaning floors, and the like.
Particles in Water:
Visible particles are generally an accumulation of iron.
You may contact a private laboratory for an individual analysis of your water. Laboratories are listed in the yellow pages. WSSC does not recommend specific laboratories and we do not do individual water analyses except to isolate or identify a system problem. We routinely test the water at specific sites within the distribution system. We do provide tap water analyses for the Potomac and Patuxent Filtration Plants and are happy to send you a copy upon request. You may also view it online.
If you have a water quality issue, please contact our Laboratory Services Group at 301-206-7575.
The “main valve” turns the water inside a property off. If you have an inside meter, check the valve near the meter. If you have an outside meter, the main valve is usually located near the hot water heater or where the service enters the property.
To operate the main valve, turn clockwise to the right (until it stops) to close, and counterclockwise to the left (until it stops) to open.
If you need the water turned off from the outside, contact a plumber or WSSC. WSSC charges a disconnection fee to turn the water off and a fee to turn the water on. A registered plumber can also make the disconnection and reconnection request for you.
Covers can be located in the street, shoulders of the road and in a customers’ yard. These covers are over water, sewer, storm drain, telephone, and gas structures. Most covers have some type of identification.
WSSC covers are located:
If you have identified the cover as water or sewer, please contact WSSC's Emergency Call Center at 301-206-4002 or send an email to email@example.com. Please provide the cover’s exact location and, if possible, the approximate size of the cover/opening.
Please contact WSSC's emergency line at 301-206-4002. We will investigate to determine the location of the leak (on or off property). The homeowner is responsible for the water service (lateral) from the house to the property line and all the pipes within the house. If the leak repair is the owner's responsibility, WSSC will confirm this in writing. If the leak is in the WSSC portion of the service or on the main, we will notify the occupant/caller. We will make repairs and restore the affected area to its original condition.
Pressure is the force of water within the system. Other terms used in conjunction with pressure are static (not changing - pressure at the hydrant before flow) and residual (pressure left in a pipe system when high water flow rates are occurring). Water pressure is measured in pounds per square inch (PSI).
Low Pressure/Flow is generally described as not enough water in the system. If the problem is low flow, you should check with a plumber. The problem may be a restriction within the pipes or a problem with just one plumbing fixture. If the "low flow" problem is found throughout the property, please call WSSC and we will check the pressure at the closest fire hydrant and your property. An adult 18 or older must be available for us to access the property. Understandably, our crews will have to address system-wide emergencies and other critical events prior to investigating low-pressure concerns.
Screens on individual fixtures (filters or aerators) may be clogged. The screens can be easily removed, rinsed and replaced.
High Pressure is stronger than normal water flow from the spigots. If pressure is too high, you can experience banging pipes, a tripped hot water relief valve or washers that quickly wear out.
A malfunctioning PRV can cause both high and low-pressure problems and maintenance is the homeowner's responsibility. You may wish to contact a plumber for an inspection.
Cleaning and Lining is a process of applying cement-mortar lining to the water main’s wall. This process rehabilitates mains that have scale, corrosion and iron and manganese build up. The build up can cause discolored water and pressure/flow problems.
Neighborhoods are selected for Cleaning and Lining based on:
The Cleaning and Lining process are performed on mains while in place and involves:
Please contact WSSC's Emergency Call Center at 301-206-4002 and provide as much specific information as possible (e.g., water is streaming, gushing, the intersecting streets). An inspector will be dispatched to investigate your concerns.
The contractor installing the water main generally installs the water service from the main to the property line. WSSC is responsible for maintaining the individual water service (lateral) from the main to the property line. Service lines (laterals) are generally ¾" to 1 ½" for private homes and up to 12" for larger commercial buildings. WSSC uses copper and ductile iron for the service.
In the past, some galvanized pipe was used. Copper pipe; however, is replacing galvanized pipe. The lateral from the property line to the house and all water pipes within the house/building are the homeowner’s responsibility. On-property water service can be copper, galvanized or plastic.
Call WSSC's Emergency Call Center at 301-206-4002. A Customer Relations Agent will review the property’s history and instruct you based on our records.
Several questions you might consider when trying to determine the possible cause of a sewer problem/stoppage are:
When a service is backing up only when the occupants are using their facilities, or the problem is not in the lowest level plumbing fixtures, we suggest contacting a registered plumber or a sewer drain cleaner for assistance. If you are unsure, please contact WSSC for assistance.
Generally, the contractor installing the sewer main installs the sewer service from the main to the property line. WSSC is responsible for maintaining the individual sewer service (lateral) from the main to the property line. Service lines (laterals) are generally 4" for private homes. The service line from the property line to the house and sewer pipes within the house is the homeowner’s responsibility.
An obstruction in the main (in the street) or service line can cause sewer odor where gasses are trapped but a backup is not occurring. The gasses can escape through manholes or the drains in customers' homes or buildings. Unless the odor is isolated to one fixture or in an upper bathroom only, WSSC will investigate. Contact WSSC's Emergency Call Center at 301-206-4002.
Also, add approximately 2 cups of water to your floor drain. If the floor drain is dry, the sewer gas from the main or service can get into the house and cause an odor problem.
Contact WSSC's Emergency Call Center at 301-206-4002. See Service Alerts for open emergencies.
There are several causes of clogged sewers. In our area, one of the main causes is tree roots that may enter at the joints of pipes or cracks in older pipe. (Roots seek water and they often force their way through the cracked pipe.) Also, broken pipe may allow soil to enter and cause a problem. Grease is also a main cause of clogged sewers. Introduced into the sewer lines, grease can harden or collect resulting in stoppages and backups.
Be careful what you put down the drain. Several items that should not be put into your sewer system are paper towels, diapers, grease, paints/solvents, chemicals, antifreeze, non-food oils, and any non-dissolvable item. Please deposit grease and food scraps into a can or the trash for disposal. Our Can the Grease fact sheet contains more grease disposal information.
WSSC and other utilities use manholes to access our underground infrastructure. Our crews also use manholes to clear stoppages. Manholes are located in the street or in a WSSC right-of-way area.
A cleanout is an entry point into the sewer service that is used to clear obstructions in the line. A clean out can be located inside or outside. An inside clean out it is often referred to as a "stack plug." WSSC maintains cleanouts located in the public area (not on private property). However, the maintenance of an inside cleanout or on the owner's property is the owner's responsibility.
Potholes are generally the responsibility of the county, municipality or jurisdiction where located.
WSSC will restore any areas impacted during WSSC construction or WSSC maintenance work. Please call 301-206-4002 to notify us of your concerns.
Storm drains are above ground open drainage ditches or below ground systems of pipes that collect and carry off rainwater. The storm drain system is not connected to the closed sanitary sewer pipe system.
The locality in which the storm drain is located handles the installation, cleaning and general maintenance of storm drains. Contact the Storm Drain Division for the appropriate county or jurisdiction:
