During the preliminary design phase of the Interceptor System SCADA project, the QST looked to expand the SCADA final design to the Middle Peninsula (MP). The SCADA Preliminary Engineering Report gave the costs for expansion to the MP at $3.3 million. This CIP is for the construction portion of this project. The design is being performed with the Interceptor Systems Pump Station Control and SCADA Upgrades and Enhancements GN012800. PROJECT JUSTIFICATION There are multiple benefits to expanding the SCADA project to encompass the Middle Peninsula: Future trends for small communities appear to be decentralized/distributed wastewater treatment systems that will require SCADA for remote diagnosis and operational control; as time goes on, the cost of personnel and the cost of transportation will drive HRSD towards more supervisory control at both the treatment plants and pump stations, starting with the Mathews Transmission Force Main (TFM) pump stations; A major portion of the existing system is obsolete and needs replacement; There are Operational and Maintenance benefits to having the same SCADA system throughout the HRSD system: South Shore, North Shore, and the Middle Peninsula; The WAN microwave ring provides a reliable communication link and the existing communication lines could possibly function as a back-up; and if the MP is added to the Consent Decree in the future, then the MP SCADA system would be upgraded to handle the reporting requirements.

Previously the membrane bioreactor (MBR) portion of the second train was used to stage and clean membranes used in the first treatment train. Membrane performance has not met expectations for some time and has required maintenance beyond what was anticipated with the original design. With the reactivation of the second train to meet flow conditions, improvements to the technique used to clean the membranes is required. To support these modified cleaning techniques several improvements are required. These improvements are identified as follows: automation of pulsed membrane backwash with chlorine addition, provision for off-line membrane cleaning, consolidation of chemical storage and metering, Equalization Tank (EQ) pumping, Ultra-Violet (UV) system improvements, and Programmable Logic Controller (PLC) additions. Plant modifications will also be designed and installed to easily accommodate the plant's planned Phase II expansion. PROJECT JUSTIFICATION Both King William Treatment Plant (KWTP) treatment trains are able to run simultaneously. The proposed upgrades will provide improved reliability and operations. The flow coming into the KWTP is currently averaging 60,0000 GPD. Development is steadily increasing flows to the plant.

The tertiary filter was formerly part of a side stream process at York River Treatment Plant (YRTP) when the YRTP provided reclaimed water to the Yorktown Refinery and has been relocated to the WPTP for repurposing at the plant. The cost and scope of the project also includes the pump station installation, associated electrical improvements, instrumentation for capturing filter/pump station operating data, and piping to convey process water to and from the filter. PROJECT JUSTIFICATION This project will make use of equipment no longer used at the YRTP and increase disinfection reliability at the WPTP. Despite maintaining an unusually high chlorine residual concentration in the chlorine contact tank, bacterial limits are often exceeded at the WPTP. The lack of reliability is due to the high levels of total suspended solids (TSS) and particulates in the effluent. A filter downstream of the secondary clarifiers will significantly reduce effluent solids, which will subsequently reduce disinfection chemical demands/costs and overall treatment reliability.
