What We Take

We Are “Away”

Most people don’t spend a lot of time thinking about what happens to the dirty water after the washing is done or the toilet is flushed, we just want it to go “away”. But what happens next is actually critical to maintaining a safe and beautiful community.

That’s where WLSSD comes in.

Wastewater from homes, businesses and industries throughout the WLSSD service area flows to the regional wastewater treatment plant through a 75-mile network of interceptor sewers.

Wastewater Treatment Process

Wastewater is treated using a biological process that mimics natural cleaning processes in area waterways. Clean water and nutrient-rich biosolids are the end products of this process.

Industrial Pretreatment and Pollution Prevention

WLSSD works with local businesses and industries to set standards and limits for their wastewater discharges and monitor industrial discharges.  WLSSD also provides public pollution prevention education to help residents reduce their environmental impacts.

Sanitary Sewer Monitoring

WLSSD regularly monitors the sanitary sewers lines each year to determine maintenance and repair needs. Sewer lines can be damaged through natural soil movement, tree root growth, and corrosion, among other causes. This damage leads to excess water entering the system which can overwhelm the sanitary sewer system and the waste water treatment plant.

Sanitary Sewer Overflows

WLSSD works with municipalities, utilities, and residents to address overflows through maintenance, upgrades, and education to help residents understand and help prevent future sanitary sewer overflows.
