The Sanitary Sewer Utility has an annual budget of approximately $14 million. Annual costs include expense for maintaining and improving the infrastructure, special compliance programs and the cost paid to WLSSD for the treatment of wastewater.

The Sanitary Sewer Utility infrastructure includes:

  • 400 miles of collection sewers 
  • 43 lift stations

The system services approximately:

  • 26,000 residential accounts

  • 4 industrial accounts

Approximately 18 million gallons per day of waste water flow through the system. During wet weather flows can increase up to six times due to inflow and infiltration (I/I).
