Site work for a water / sewer project in Waterbury, Connecticut. Completed plans call for site work for a water / sewer project.

Third Water Transmission Main Rehabilitation-Sliplining The Work to be procured consists of: Rehabilitation of the Third Water Transmission Main using slip lining method, the project work includes the partial removal and subsequent slip lining, or compression fit pipe lining, of the existing prestressed concrete cylinder pipe (PCCP) with a high density polyethylene (HDPE) pipe, including all traffic control and site restoration. Contact Information mmccauley@waterburyct.org Question Deadline 09/06/2024 at 2:00 PM ET SCOPE OF WORK A. Furnish all labor, materials, equipment, and incidentals required and install high density polyethylene pipe, fittings, appurtenances and required adapters by using the compressive fit lining method of installation for pipes of various sizes. This work shall include complete and proper installation, testing, and restoration of underground water mains and environmental protection and restoration as shown on the Drawings and specified herein. B. The compressive fit lining method will repeat the method, outlined below for each section of pipe being installed. These processes may be performed in series or in parallel with other sections of pipe within the project; however, each section will require these steps. The outline below of the process does not dictate the means and methods of the Contractor but provides an overview of the compressive fit lining process. 1. Deliver notice of service outage to each affected property Owner in advance of work 2. Chlorinate a length of product pipe that yields passing bacteriological test results for potable water per American Water Works Association (AWWA) and any applicable regulatory authority 3. Perform hydrostatic test of the product pipe section 4. Excavate an access pit at one end of the section down to pipe grade for placement of the any necessary equipment 5. Excavate an insertion pit at the opposite end of the section down to pipe grade for entry of the product pipe 6. Excavate any service or lateral connection pits 7. Isolate the section to be rehabilitated from the rest of the system to maintain pressure integrity of the system as well as preventing any backflow of chlorinated solution or non-potable water into the system 8. Excavate and remove hydrant tees, valve tees, valves, or other connections from the host pipe 9. Assess the condition of the inside of the existing pipe to determine the appropriate process for cleaning, removal of any obstructions and preparing the inside of the existing pipe 10. Clean the interior of the existing pipe using the appropriate cleaning devices, such as sprayers, scrapers, etc. 11. Prove the interior size of the existing pipe by pulling through a foam pig which matches the OD of the pipe to be inserted as a compressive fit liner. If the foam pig doesnt clear any sections of the existing pipe, additional effort may be required to remove the obstruction 12. Assemble the rod string or cable as it is thrust through the host pipe from access pit to insertion pit
