All correspondence must be made through the Vendor Portal. Specifications include, but are not limited to: Based on the latest alternative evaluation, the design of the project is anticipated to include a new gravity trunk line from the Rodgers Pump Station to the Mifflin Road Pump Station, demolition of the existing Rodgers and Mifflin Pump Stations, a new storage equalization tank at the Mifflin Site, and replacement of the Mifflin Road Pump Station and the force main from Mifflin Road to the Streets Run Sanitary Trunk Sewer. The design of the proposed new consolidated station shall address all concerns from the CISA Security Assessment Report and bring the facility within compliance with PWSA and all regulatory standards.

The design of the proposed new consolidated station shall address all concerns from the CISA Security Assessment Report and bring the facility within compliance with PWSA and all regulatory standards. • Perform design services for a new gravity sewer, demolition of the existing Rodgers Pump Station, new storage equalization tank at the Mifflin Site, and replacement of the Mifflin Road Pump Station and the force main from Mifflin Road to the Streets Run Sanitary Trunk Sewer. The storage equalization tank and pump station shall be designed to handle potential flow reductions that could result from private sources. • Gravity Sewer and Force main design shall include the alignment, hydraulic design including but not limited to profile development and transient analyses, all appurtenances, testing and material requirements, hydrogen sulfide management analyses, easement acquisition, all permitting related to, and certification as required. • Perform field investigations and desktop analysis, as applicable, to develop a preliminary design for recommended pump station replacement and necessary storage equalization tank, including but not limited to flow monitoring and inspection of the existing infrastructure. • Design must include replacement of the pump station, pump upgrades as needed, and general building & site improvements. The design of the new facilities building will need to provide protection to all equipment, including but not limited to all motors and pumps, SCADA control panel, electric feed, backup power supply, and vacuum pumps. (Tasks 1 and 3, as noted in Attachment 7.) • Develop the facility design to include perimeter security measures, entry controls, electronic security systems, and illumination. Consultant is to design conduit only for building security and PWSA will provide equipment. • Consultant shall include in the design, permanent site access improvements to allow safe access to pump station including all necessary permits for improvements. • Consultant shall conduct necessary asbestos testing, obtain permits for and design plans for demolition of the existing Rodgers and Mifflin Pump Stations. • Design shall include considerations for bypass as required or phasing if the new station is to be built while the old station remains operational. Design must consider construction access and staging. The site is currently accessed by an existing concrete bridge over the unnamed tributary to Thompson Run. This bridge is not adequate to support construction traffic. A temporary bridge is required for traffic crossing the stream.
