M-DWASD South Miami Heights Water Treatment Plant

Project Description:
New South Miami Heights Water Treatment Plant – The Miami-Dade Water & Sewer Department awarded a contract to Camp Dresser & McKee, Inc. (CDM) with EBS Engineering, Inc. as one of its subconsultants to design a state-of-the-art automated membrane softening water treatment plant for South Miami-Dade County – to accommodate the growing demand of the area. The new plant will built in two phases – with initial treatment capacity of 20 million gallons per day (20 MGD), which will be expendable to 60 MGD. The design for initial Phase included concrete structures to house electrical generators, booster pumps, filters, membranes, degassifiers, chemicals, high service pumps, and multi-purpose (office/maintenance) two-story building. Along with two 5-million gallons tanks and an elevated (150 feet) storage tanks.

    Environmental Engineering Services:
    EBS provided environmental services to conduct Phase I and Phase II site assessment/ subsurface investigation for the approximately 20 acres parcel plant site. The Phase I was conducted as per all applicable regulations and in general accordance with the ASTM 1527-00 to document any recognized environmental conditions (RECs) that may have impacted the site. EBS later performed Phase II for the site to investigate the potential impacts of the RECs to the soil and groundwater.
    EBS also performed pre-demolition asbestos survey in selected parcels or buildings along the corridor – including field sampling, analysis of samples, and preparation of final reports with recommendations for proper handling of any asbestos-containing materials found.
    Plant, HVAC, Piping Design and Specifications:
    EBS provided complete heating, ventilation and air conditioning (HVAC) and piping design of the entire treatment plant and wellfields. EBS developed construction drawings and specifications for membrane treatment building including Lab and office space air conditioning; Process Bay and Maintenance Workshop ventilation; Pre & Post treatment building ventilation; and wellfield electrical room, guardhouse and generator building air conditioning.

    EBS also provided sanitary and domestic water distribution and gas piping design for membrane treatment building including lab, offices, process bay, maintenance workshop; pre & post treatment building, guardhouse, and emergency shower/ bathroom plumbing. Prepared construction drawings, specifications and energy calculations – computations for compliance with the state energy code for all the buildings.
