Water Quality Master Plan – NCS developed a Master Plan to mitigate drinking water quality issues for nitrate, chromium, TDS, and arsenic. Based on the results of the evaluation, water treatment technologies were selected and a Capital Improvement Program (CIP) was developed. Several processes, depending on the well site, were identified for implementation, these included GAC, ion exchange (IX), RO, and coagulation/filtration technologies along with blending.
Gateway Treatment Facility Expansion – NCS was prime design firm for the 1,700 gpm nitrate plant expansion that included a new 3-vessel IX system, prefilters, site expansion, brine tanks, backwash and waste tanks, controls, pumping systems, and civil/site elements. The custom designed system featured upflow regeneration and air scour features.
Steel Tank Rehabilitation – For the past four years, NCS has provided design & CM services for several steel tank rehabilitation projects. These projects involved the recoating and structural rehabilitation of the Northside, Rancho Santa Fe, and Coldwater tanks. Piping, valve, safety, and site improvements were also included. The Northside project was a fast track project where NCS completed the design in 30 days.
Coldwater Chlorination Facilities – A new chlorine on-site generation system was designed to meet the chlorination needs for all the wells at one location, as well as providing chlorination for the potential nitrate treatment facility at the site. The combined well flow varies based on seasonal system demands, combination of wells in operation, etc. The project includes a new prefabricated concrete building, 200 lbs/day Microclor unit, two metering pump skids, new PLC and HMI, brine maker, chlorine solution tank, flow metering vault, yard piping, HVAC and structural components.
