Explanation
1. BACKGROUND: During the original contract the Engineer conducted a review of the existing sewer system, with the purpose of planning the implementation of a real time control (RTC) strategy. The goal of RTC is to reduce overflows, plant bypasses, and DOSD operational costs. The original phase of the contract identified areas within the collection system that would benefit from RTC, and those that would not. Operational constraints and existing modeling was studied and used to propose the initial RTC implementation plan.
This contract renewal will expand the RT-DSS developed in Modification No.1. Rainfall data and new flow monitor locations will be used to develop optimized control strategies for dewatering the OARS tunnel and operating CEPT. Historical rainfall data will be added to the RT-DSS screens and a “flight-simulator” will be developed that will allow the operators to simulate operation of the collection system during different rain events using the RT-DSS interface providing modeled recommendations.
This Contract renewal also will provide BLU-X engineering portal for long term continuous data viewing. Sensors that are integrated with SCADA will be shown in the engineering portal in an organized fashion. The engineering portal will also include a map of the location of rain gauges, level sensors, meters’ temperature sensors, and flow monitors currently integrated into the SCADA system or One-Rain system.
The planning area is 99 (Citywide).
