MOSES LAKE - The Moses Lake City Council approved an emergency declaration Tuesday night to address the failing sewer siphon that led to the Aug. 28 sewage leak into the lake.
The resolution declaring an emergency allows the city to waive the formal bidding process and immediately hire a contractor for the project.
The sewage spill on Aug. 28 was caused by a hole in the Knolls Vista siphon, causing about 64,000 gallons of raw sewage to be released into the lake, according to city officials. City wastewater employees installed a stainless steel band to stop the discharge.
“The existing sewer main siphon from Northshore Drive and Broadway Avenue has experienced multiple breaks in the past few years,” stated Fred Snoderly, the city’s Municipal Services director.” This is due to the age and deterioration of the steel pipe that has been in service for several decades.”
The sewer line project includes re-routing of the sewer mains for Northshore Drive to take the deteriorating pipe out of service in the area where the breaks have occurred. Engineer estimates put the cost of the project at about $350,000.
Snoderly said the city also plans to begin addressing other decades-old sewer lines that run under the lake, likely multi-million dollar projects to replace the lines.
