Why should I apply for the rebate?
- Save money! These septic system and side sewer rebates go directly to the contractors you hire to do the work. This means you do not have to pay the qualifying rebate amount upfront and wait to get reimbursed — an automatic savings!
- Keep you and your family healthy — Household wastewater is loaded with bacteria and viruses. Overlooking (or delaying) septic or side sewer maintenance poses harmful health hazards that can lead to illness or disease. A properly functioning septic system or side sewer helps remove these pollutants so well water and nearby waterbodies aren’t contaminated.
- Protect the environment — Failing wastewater systems release bacteria, viruses, and other materials that can enter streams, rivers, lakes, Puget Sound, and the ocean. The pollutants harm local ecosystems and can harm native plants, fish, and shellfish, and the people who eat them.
- Protect your property value — An unusable septic system, or a side sewer in disrepair, lowers your property value. When you sell your home, you’re legally required to disclosing a septic system failure (RCW chapter 64.06). It can also be an expensive liability if you have to repair or replace the system, which costs around $15,000 to $40,000.
