Body
SUMMARY:
The City has initiated a comprehensive maintenance program to clean, inspect, rehabilitate and repair existing sanitary sewer pipelines and manholes throughout the City of Clearwater. The program objective is to maintain the integrity of the sanitary sewer system and minimize disruptions in service to our citizens.
February 5, 2015, City Council awarded 2-year contracts to Layne Inliner, LLC for Sewer Cleaning and Televised Inspections and Hinterland Group, Inc. for Trenchless Rehabilitation based on unit prices.
Layne Inliner’s contract includes cleaning and TV inspection of selected sanitary sewer systems. This process restores capacity by removing sediment and obstructions and also accurately identifies defects that require corrective action.
Hinterland Group’s contract includes lining of selected sewer pipeline to rebuild the pipes’ structural integrity according to City Standard Specifications, limiting inflow and infiltration.
From televised inspections staff reviewed and found it is necessary to have more cleaning and trenchless rehabilitation work done to stop major infiltration and pipe failures.
Both contractors have performed excellent work for the City and agreed to hold their competitive unit pricing to continue the work for the City.
Public Utilities staff will coordinate and direct contractors, on an ongoing basis, to those areas as needed to meet program goals.
