ENGINEERING SERVICES FOR THE CITY OF RENTON
2022 SANITARY SEWER REPLACEMENT PROJECT
BACKGROUND
The City of Renton Wastewater Utility implements an annual sanitary sewer rehabilitation and/or
replacement project as part of its ongoing capital improvement program. For the year 2022, the
City will be undergoing a replacement project consisting of various sewer main, manhole, and side
sewer replacements within the City’s system.
The sewer infrastructure to be replaced as part of this 2022 Sanitary Sewer Replacement Project
were selected by the City of Renton based on field observations and inspections and are located
within City right-of-way and on Private property within City easements at seven different general
sites (see City provided site maps illustrating the proposed work following the Scope of Work).
Work within the City right-of-way will take place on Kirkland Ave NE and NE 16th St (Site 1),
NE 4th St (Site 2), NE 6th St and NE 7th Pl (Site 3), Tacoma Ave NE, NE 6th St, and
Shelton Ave NE (Site 4), NE 6th St (Site 5), Taylor Ave NW and NW 7th St (Site 6). Work on
private property within existing City easements will be required off Monroe Ave NE (Site 7) and
various points on other sites where access is needed for system abandonment.
The Project includes the construction of approximately 1,600 lineal feet (LF) of 8-inch sewer main,
approximately 120 LF of 12-inch sewer main, approximately 13 sewer manholes (7 manholes to
be abandoned), and approximately 32 service laterals (24 service laterals to be abandoned).
These quantities will be further refined during the alternative analysis and design.
The scope of work for this phase of the project will include:
x A project area survey and creation of a project basemap.
x Geotechnical explorations and analysis.
x An alternatives analysis of various project elements.
x Summarizing the preliminary design findings and alternative analysis in a Basis of Design
Report (BODR).
x Design of the replacement of the sewer mains, manholes, and service laterals selected for
the Project.
x Providing permitting and public outreach support during the design process.
x Supporting the City during the bidding process.

Project will be scoped and completed as part of a future phase.
