Stantec was retained by MDWASD to provide Design Services related to Consent Decree Projects at all three Wastewater Treatment Plants (Central, South and North District). METCO, as one of the subconsultants, is responsible for developing Design Report and Detailed Design Documents related to Electrical, I&C and HVAC system improvements in various process areas at these Wastewater Treatment Plants.
As part of the Master Contract for the Program, METCO was tasked to develop Preliminary Design Task Memorandum, Detailed Design Documents and Construction Assistance Services for the Secondary Clarifiers at the North District –Wastewater Treatment Plant (NDWWTP).
- METCO was responsible to provide the above services for the following key project elements:
- Replace Electrical Power System to Secondary Clarifiers No. 1-6 and associated Auxiliary System.
- Replace MCC’s and Feeders to all connected loads in the Primary Sludge Pumping Systems 1 & 2.
- Replace Lighting System in the Pump Station.
- HVAC System Upgrades at the Primary Sludge Pumping Station.
Limited space constraints and WASD requirements to maintain minimum interruption to the Clarifier operations during the Construction Phase were some of the challenges METCO considered while developing design documents.
