Even when problems are not visible above ground, Ronald Wastewater District routinely performs preventive maintenance to ensure sanitary sewage collection systems operates safely and efficiently. To that end, they have scheduled four capital improvement projects to be completed in 2013. The majority of these projects involve replacing existing eight inch concrete pipe lines, which have a high defect rating and maintenance problems, with eight inch high density polyethylene (HDPE) plastic pipe.

The first project, which will begin in early March, was awarded to Budget Sewer who submitted the lowest bid of $782,260 (between 2% and 8% below the engineers’ original estimate). Budget Sewer will replace 2,340 feet of pipe on the following main sewer lines:

• 12th Avenue NE from NE 175th St to 17211
• N/S Easement line at 17302 12th Ave NE easterly 328 feet
• E/W Easement line between NE 175th St and NE 174th St from the Library to 114 NE 174th St
• 13th Ave NE from NE 170th St to the north end of St
• 15 additional locations around the City of Shoreline to replace District stubs (the 6" pipe from the main line to the property line).

The second and third rehabilitation projects (which are not yet ready for bid) will replace the pipes on the following main sewer lines:

• 5th Ave NE from NE 175th St to NE 170th St
• 5th Ave NE from NE 155th St to NE 145th St

Lastly, the District will address a major hydraulic upgrade in the Ridgecrest area on 11th Ave NE, from NE 175th St to NE 168th St. The goal of this project is to provide greater collection system capacity, in response to City zoning changes that will allow a higher population/housing density in this area. Approximately 4,640 feet of eight, ten, twelve and fifteen inch concrete pipe will be replaced with ten, twelve, fifteen and eighteen inch HDPE pipe respectively. The District will also replace the residential side sewers that connect to these main lines at no addition cost to the customer.

Ronald Wastewater is a special purpose district focused on the operations and proactive maintenance of the sanitary sewage collection system serving the corporate limits of the City of Shoreline (excluding The Highlands), parts of unincorporated Snohomish County, a portion of the Town of Woodway, the City of Mountlake Terrace, and the Highlands Sewer District.
