Overview

Summary

West County Wastewater ("WCW") is accepting sealed bids via their e-Procurement Portal, OpenGov until Friday, September 25, 2026 , 4:15 pm PST. Late submissions shall not be accepted.

WCW has contracted with Pressure Pipe Consulting Company (PPCC) to perform an in-line assessment of the Tara Hills Force Main. The assessment will require launching and receiving a series (approximately 3) progressive pigs and one (1) diagnostic and mapping pig (probe). To perform this in-line phase of the assessment, Civil work is required to install a Launch Barrel, install a Receive Barrel, and remove a plug valve and replace it with a full-port gate valve. By-passes and line-stops will be required to perform this work. Additional scope to assess the pipe condition will also be performed by electromagnetic thickness testing. For the consultant to perform this exterior analysis phase of the condition assessment, potholing must be provided by the Civil Contractor to enable access to the pipeline crown. The civil work scope also includes assisting the assessment pigging/probe consultant in launching and retrieving the pigs and probe. The Civil Contractor will also be required to restore site conditions at the (3) locations where civil work is performed and at the location of potholes. The locations of the proposed work sites are specified in the bid documents. The Civil Contractor will also assist the Assessment Consultant by providing support with tasks to insert and retrieve the pigs and the probe, and to supply supplemental water.
