Water & Sewer

SEWER - what NOT to flush
Disinfectant wipes, personal wipes, baby wipes, paper towels, and other similar materials should not be flushed down toilets.  Personal wipes are especially misleading because they are often labeled "flushable", but they can clog sewer pipes and lead to blockages in the pumps that are part of the City sewer systems. In recent weeks, we have observed a surge of wipes in the sewer system, which can cause pump blockages and a greater potential for backups. The photo to the right shows the damage these wipes can do to the system.

Waste treatment systems are designed to handle human waste and toilet paper only.  Please take your responsibility seriously.  Wipes and other items cause problems in the pipes inside your home. Clogged pipes can lead to overflowing toilets, basement sewer backups, and the need to clean out the main drain. Thank you for your help in spreading the word!

Results from PFAS testing by State of Michigan - The results show that of the PFOA and PFOS compounds tested, the chemicals were not detected in the City's water supply; therefore, levels are below the EPA's LHA level.  Click here for entire notice.


The water distribution in the City serves a population of approximately 3,850.  It provides potable water service to residents within the City, as well as portions of WilliamstownTownship through the 425 service agreements.  The system is comprised of a water treatment plant and five (5) well pump stations, and approximately  116.61 million gallons of water, or approximately 319,482 gallons per day and treated with chlorine.  

The sanitary collection system in the City serves a population of approximately 3,850.  It provides sanitary sewer service to all of the current residents within the City, as well as portions of Williamstown and Wheatfield Townships through the 425 service agreements.  The system is comprised of nine (9) pump stations, approximately three miles of force main, and twenty-one miles of gravity sanitary sewer. 

The Treatment facility was first designed in 1954 and expanded in 1971 and 1988.  The construction in 1971 converted the plant from a primary facility to a secondary facility with activated sludge, anaerobic digestion and filtration.  In 1988 the facility was expanded to meet the city's growth demands and more stringent effluent limitations.  In August of 1996 the City completed a Wastewater Treatment Plant Master Plan and a Sewer Master Plan in January 2005 that addresses future plant and sewer improvements. 


For years, Williamston has complied with an important Regulatory Water Safety Compliance Program known as Cross-Connection Control.  This State Mandated Program focuses on non-residential (commercial) water service connections and onsite visual inspections (coordinated and performed by HydroCorp of Troy, MI) to identify potentially harmful interconnections to the Willamston Public Water Supply.  Learn more about the Cross Connection HERE.


Starting in August 2019, the City's water and sewer bills will be generated on a monthly basis.  Each bill will be mailed no later than the 10th of each month and will be due the last Wednesday of the month.  A 10% penalty will be added to any unpaid balance the day after the bills are due.  If a balance remains, water shutoff for non-payment will occur the third Wednesday following the bill due date.  Failure to receive your bill does not waive the past due penalties.  When reading your bill, an explanation of codes is listed on the back. Bills are based on usage, so each customer’s billing amounts will vary (number of people, washing machine, dishwasher, gardening, etc.), so it is not practical to compare your bill with another customer.



You have several options for paying your bill…. you can mail it to us, you can come directly to City Hall and pay with cash, check, money order, credit/debit card, or you can drop your payment in the secure drop box which is located on the west side of the door to City Hall. Check with your financial institution to see if online bill paying is available directly through them. We currently accept credit/cards on our website (www.williamston-mi.us).  There is a fee associated with this service.  We also offer ACH payments.
