Moses Lake sewer pipe work underway
Cheryl Schweizer/Columbia Basin Herald Construction workers dig a trench on North Central Drive in Moses Lake Monday morning, part of a project to upgrade the wastewater treatment system in the Knolls Vista neighborhood.
MOSES LAKE — Replacement of some wastewater pipes in the Knolls Vista area should be completed by mid-May.
Currently, crews are replacing wastewater lines along North Central Drive near Knolls Vista Elementary School. The project also includes line replacement on Knolls Vista Drive, tying into a lift station on Northshore Drive. A lift station pumps untreated water from a lower elevation to a higher elevation.
City engineer Richard Law said replacing the old lines will allow the city to close a lift station in the Knolls Vista area. The project includes installation of about 1,700 feet of 15-inch sewer line, 1,700 feet of eight-inch sewer line, five new manholes and five new stormwater catch basins. The new system will be able to take better advantage of gravity to help move water, Law said.
A second wastewater project is underway on Wheeler Road, A new “force main” is being installed to improve water flows. Force mains use pumps and compressors to move untreated water through the wastewater pipes to the lift stations.
The goal is to improve service along Wheeler Road, for existing customers and new businesses, and provide capacity for development.
Advanced Excavation, of Moses Lake, is the contractor. The project is estimated to cost $488,679.
