Construction Updates

Current and Upcoming Construction Projects

Maintaining and improving our wastewater treatment systems is an ongoing effort that requires many capital construction projects. These projects take place at the Budd Inlet Treatment Plant, offsite facilities, pump stations, and LOTT’s sewer interceptor pipelines. LOTT has multiple capital projects underway at any one time. Check back occasionally for updates on ongoing and upcoming projects.

LOTT Construction Impacts

Some construction projects may cause disruptions beyond LOTT property boundaries. When construction is likely to cause disruptions, LOTT strives to alert residents and business owners who may be affected.

City and County Road Construction

City of Lacey, City of Olympia, City of Tumwater, and Thurston County also complete improvement projects on sewer pipelines and other public infrastructure that at times, result in traffic or other disruptions. Find information and project location maps for their projects at the links below.

Biological Process Improvements

This is a major construction project to optimize the biological treatment process that removes nutrients from wastewater. It will also greatly improve the energy efficiency at the Budd Inlet Treatment Plant. Construction began in 2020 and was completed in 2023.

Digester System Improvements

Several phases of work are planned to update the sludge digestion system, which was originally built in 1982. Phase 1 work, currently underway, includes upgrades to safety equipment and an improved sludge mixing system. Phase 2 work includes new digester covers and replacement of the emergency waste gas burner with an enclosed flare. This phase is under design, with construction likely to begin in 2024.

Mechanical Upgrade

This project includes the replacement of auxiliary mechanical systems at the Budd Inlet Treatment Plant. Construction began in 2021, but was temporarily suspended due to equipment delays from the manufacturer. It is once again underway.

Security Improvements

Installation of new fencing around the treatment plant perimeter, LOTT offices, and the East Bay Public Plaza was completed in 2022. A follow-on project to replace two vehicle gates is scheduled for later this year. These efforts will result in greater security of the Budd Inlet Treatment Plant and related facilities.
