Improvement projects

Find information about construction and improvement projects at West Point.

Power quality improvement

Power disruptions at West Point can cause equipment shutdowns. When this happens during heavy rain, the facility is overwhelmed and untreated wastewater and stormwater flows into Puget Sound. The purpose of this project is to rapidly identify and implement solutions to improve the reliability of the plant's electrical power supply. 

Learn about the power quality improvement project at West Point to eliminate emergency bypasses of wastewater caused by power disruptions.

Active and planned projects

These capital improvement and asset management projects focus on protecting worker and public safety and the environment while protecting ratepayer investments by improving system reliability and increasing efficiency. The projects to replace, repair, and upgrade the equipment and facilities at West Point will help us continue to protect public health and the environment, serve more than 700,000 residents, and treat 100 million gallons of wastewater per day. We welcome your feedback and will provide regular updates about our progress

Raw sewage pump replacement

The purpose of this project is to replace the raw sewage pump system and implement structural improvements to the facility. Construction is expected to begin in 2024.

Biogas pipe replacement

The purpose of this project is to replace parts of biogas piping connected to the digesters at West Point that have leaks or corrosion.

Sedimentation tanks seismic upgrade

West Point is undergoing upgrades to make the facility more resilient in the event of an earthquake. We are improving large enclosed sedimentation tanks that play a key role in the wastewater treatment process.

Completed projects

Power monitoring upgrades

WTD has a comprehensive maintenance program for all of its facilities. As part of our system maintenance, the four electrical switchgears were replaced at West Point.
