The Village’s Sewer Division is responsible for maintaining the Village’s wastewater collection system and treatment plant.  As much as 750,000 gallons of wastewater are treated daily at a recently expanded treatment plant, which allows the Village to meet or exceed requirements established by the Wisconsin Department of Natural Resources for discharge of water.

Sewer Division – Greg Richter, Head Operator 

Sewer Division is located at 901 Gatewood Drive in Twin Lakes.  The Sewer Department can be contacted by calling 262-877-3404 (During weekday hours of 6a.m. to 2:00p.m. or in non-emergency.)


* In the event of a sewer back up, contact Sewer Division staff via the Police Department at 262-877-9056!*

Sewer Back Up

In the event of a sewer back up into a home or business, customers are encouraged to contact the Village immediately so that Village staff can determine whether or not the main sewer line is clear before the resident incurs professional charges from a plumber.  Contact Village staff via the Police Department at 262-877-9056 in the event of a sewer back up. Please note that the Village is not responsible for damages related to sewer backups.


Think pouring grease down your drain is ok as long as you run hot water?  Think again.  Grease should NEVER be poured down the kitchen sink.  Once it hits our sewer lines it immediately cools and hardens.  This is just one of several chunks of grease we removed from Lift Station 3 by Twin Lakes Park.  PLEASE pour your grease into a glass jar or other receptacle to throw out with the trash.  DON’T pour it down the drain!

Sump Pump Discharge

Sump Pump Discharge must NOT be directed to your house sanitary sewer system.

Swimming Pool Drainage

Residents with swimming pools MUST contact the Sewer Department before draining the pool into the sanitary sewer system.

Water Softeners and Salt

Most of us soften the water we use in our houses and businesses.  Unfortunately, the salt, or Chloride, we used ends up in our wastewater and ultimately in Bassett Creek and the Fox River.  Please adjust your water softener to reduce the amount of chloride in our wastewater.  Simple actions by property owners can help save the Village from costly systems to further treat the water leaving our sewer plant by removing chlorides.  The Village encourages all residents to reduce the amount of salt flushed down the drain each time a softener regenerates and to minimize regenerations by ensuring your softener is working properly and is regenerating based on the amount of water used in your household or business.
