Lift Station Improvements
A lift station is a pumping facility that moves wastewater from lower elevations to higher elevations. Incorporating lift stations at certain points in a gravity pipeline system is integral to moving sewage to a wastewater treatment plant efficiently and cost-effectively.
Silver Lake currently has has 21 sewer lift stations in our wastewater system, several of which are 20 – 30 years old, and coming to the end of their service life with similar maintenance issues. In response, the District is planning to rehabilitate several of these existing lift stations over the next two to three years, and bring another three new lift stations online soon.
Below is a summary of each lift station project’s scope, cost, and timeline. If you have questions about these or any of our other projects, give us a call at (425) 337-3647.
