Contract 1 - Scope of Work - The work will consist of two main areas at the WWTP at 315 Curry Hill Road, Canonsburg, PA 15317 as follows:
Plant Pump Station Influent Chamber Bypass Lines – The work will consist of excavation to locate the 18” and 24” forcemain lines from the Michigan Avenue Pump Station where they enter the Plant Pump Station influent chamber. A tee will be added on each line with manual isolation plug valves on each branch line to isolate and divert flow directly into the plant PS wet well. Concrete holes shall be drilled into the wet well from the exterior for the new bypass branch lines and link-seal used around the pipes. The valves shall all be located below grade and provided with valve boxes at grade.
One of the two forcemain lines shall remain in operation at all times (unless bypass pumping is provided by Contractor) which will require plugging of the other line at the influent chamber which is currently under construction. Bypass pumping of the 30” D.I. combined gravity sewer from North Strabane Southpointe and Western Center shall be provided into the Plant PS wet well.
Biotower Recycle Line – The work will consist of excavation to locate the 36” forcemain line from the Clarifier Pump Station which connects to the final clarifiers. A 36” x 24” wye-connection will be added with a 24” manual isolation plug valve on the new recycle line to recycle flow into the Biotower PS wet well. The valve will be located below grade and be provided with a valve box at grade. A new concrete vault will be installed on the recycle line to contain a new 24” mag flow meter and modulating flow control valve. Concrete hole drilled into the biotower PS wet well from the exterior for the new recycle line with link-seal used around the pipe.
On the 36” clarifier PS forcemain, after the wye-connection a new concrete vault will be installed for a new 36” 316L SS static mixer. A new PAC PTFE dosing line will be run from the Clarifier PS building to the new static mixer vault through a SS line. Heat tracing shall be provided for freeze protection of the PAC dosing line and injection quill assembly in the vault. Bypass pumping from the Clarifier Pump Station to the Final Clarifiers shall be provided during construction by the contractor.
Electrical power and control wiring and conduit from the two new vaults to the existing panels in the two pump station buildings shall be provided per the electrical plans and specifications as part of Contract 1.
