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).
1.1 Amount of additional funds to be expended: $519,832.41
Original Contract $ 741,036.22 PO003393
Modification 1 $ 519,832.41 PO153805
Renewal 1 (this ordinance) $ 518,273.78 (TBD)
CONTRACT TOTAL $1,779,142.41
1.2 Reasons additional goods/services could not be foreseen:
Renewals were planned for this project/contract.
1.3 Reasons other procurement processes are not used:
The current consulting firm has spent significant time and resources familiarizing themselves with the City’s sewer system, hydraulic models, and operational constraints. They have put together the plan for how they will implement the RTC technologies. There would be duplication of these efforts if it were to be bid out at this time. Bidding the project again at this time, would slow the progress and delay RTC implementation.
1.4 How cost of modification was determined:
The cost was determined by negotiations between EmNet, LLC and DOSD
2. Project Timeline: It is anticipated that the work should be complete by the end of 2020.
3. CONTRACT COMPLIANCE NO.: 20-1118177 | MAJ | EXP 11/02/2020 | 001012
4. Emergency Designation: Emergency designation is not requested.
5. ECONOMIC IMPACT: Real time control is expected to optimize the City’s wastewater treatment plants by maximizing sewer storage and conveyance, maximizing treatment, and reducing overflows. Reduction of overflow will have positive environmental benefits to receiving streams and public health.
6. FISCAL IMPACT: This ordinance authorizes the expenditure of up to $518,273.78 from the Sanitary Sewer General Obligation Bond Fund 6109 and amends the 2019 Capital Improvements Budget to provide sufficient budget authority.
