Septic to Sewer Rebates

Incentives to Encourage Septic Conversion

LOTT is offering a rebate of 50% to 75% off the LOTT connection fee for property owners that are converting from an on-site septic system to the public sewer system. This program is in effect from 2019-2024, and is subject to available funds.

Property owners converting from septic to sewer are eligible for a rebate of 50% of the LOTT connection fee. Owners who meet criteria for hardship status, as defined by the city that will provide utility service, may qualify for an additional rebate of 25% of the LOTT connection fee.

To apply, complete the application form below and submit it to the city – Lacey, Olympia, or Tumwater – that will be providing utility services to the property. City and LOTT staff will review the application, determine rebate eligibility, and send you notification of the rebate amount. When charges for connecting to the sewer system are paid to the city, you will receive the rebate as an "instant" discount off the cost of the LOTT connection fee. You will be responsible for payment of the remaining portion of the LOTT connection fee not covered by the pre-approved rebate.

LOTT is offering this incentive program to encourage property owners within LOTT’s service area to abandon on-site septic systems and connect to the public sewer system. This benefits LOTT and the community by:

  • Helping protect water quality of local groundwater, lakes, streams, and inlets
  • Protecting LOTT’s continued ability to discharge to receiving waters
  • Spreading the cost of operating the public sewer system over more ratepayers, lowering the costs for all
  • Gathering data that can help guide future efforts to encourage septic to sewer conversion
