SCOPE OF WORK
KENNYDALE LAKELINE SEWER SYSTEM EVALUATION
PHASE 2B
SCOPE OF SERVICES
The following Scope of Services has been developed to assist the City of Renton(City)with the Kennydale Lakeline
Sewer System Evaluation.The objective of this project is to provide a comprehensive system analysis for the
Kennydale Lakeline Sewer System(Lakeline System)that will address the City's short and long term issues concerning
the system.The following tasks under the Scope of Services have been prepared based on Carollo Engineer's Team
(Consultant)current understanding of the proposed project and on-going discussions with City staff.This phase of the
Scope,2018 Activities,will design and provide construction services to install two new manholes in the Lakeline,clean
the Lakeline,provide recommendations for future cleaning activities,and update the remaining useful life based on
new data acquired as part of this Scope.Subsequent phases will conduct an alternatives analysis for future
improvements, and potentially repair or rehabilitate infrastructure to facilitate the operation and maintenance of the
Lakeline System.
PROJECT BACKGROUND
The Lakeline System was originally constructed in 1972 consisting of a flush station, service laterals, Lakeline,and lift
station.The Lakeline consists of approximately 4,800 linear feet of 8-and 10-inch pipe with 6-inch lateral connections.
The material of the Lakeline and laterals will be confirmed as part of this scope of work.The Lakeline is a low pressure
force main that was installed at or near grade of the lake bed; resulting in adverse sloped segments and several large
sags.Lateral connections were outfitted with shut-off valves in 1986 to allow line cleaning;however the effectiveness
of these valves were ineffective and are no longer used.In 2003,the City conducted a condition assessment and
predesign report that will serve as a reference for the current project.
In 1994,the Lake Washington No.2 Lift Station was replaced. In 2004,the Lake Washington Flushing Station was
rehabilitated.A recent assessment of the City's Force mains and Lift Stations has identified these stations as high risk.
