Moses Lake is soon to hire contractors for a $685,115, 75-day, annual sewer upgrade to fix broken parts, among other things.

The project includes the installation of approximately 1,845 feet of PVC sewer line of varying widths, repairs to the existing sewer line, an additional sewer bypass and a new concrete vault for that bypass.

Contractors will also remove around 720 square yards of pavement and concrete, followed by grading, paving and installing a parking area, a concrete retaining wall, a driveway and a sidewalk at the Central Operating Facility on Lakeside Drive.

In addition, underground electrical work needs to be done: about 200 feet of a six-inch water main, the relocation of an electrical circuit breaker, irrigation sprinkler controller and a telemetry radio antenna for wastewater data collection.

Four structures will be demolished in the project, including an old headworks building, an old well pump out by Big Bend Community College that is no longer in use, and two structures serving as a former police firing range off Randolph Road. Meanwhile, a new building will be erected with electrical work.

These upgrades will cover broken parts, said Moses Lake design engineer Mark Beaulieu. The bypass connection pipe will help the flow convenience, and rerouting will help take the load off other wastewater stations.

The city has a million-plus dollar budget for annual sewer upgrades, said city engineer Richard Law. Yearly for more than 70 years, they’ve been doing maintenance here and there.

“These are all small spot repairs,” he said. “We just lumped them together in one larger project so hopefully we can get interest from a contractor to make it worth their while to come.”

Residents will not be impacted by the work, he said.

The deadline for contractor applications is May 5. At that time, a contractor will be selected and begin the upgrades.

“There’s nothing remarkable about this. It’s just cleanup work. Just ongoing maintenance for different areas,” Law said. “Some spot repairs, other things that we need to get done just to keep the system moving. Just keep it working.”
