Potable Water Treatment

Many of our water supply projects require some consideration for water/chemical treatment, including disinfection, adjustment of pH, fluoridation, corrosion control and/or treatment for iron and manganese. Projects completed during our 25 years of experience have included the following scopes of work:

Upgrade of ten (10) separate chlorination stations located throughout the water distribution system at the New Port Naval Station, including advanced injection and control systems. Residual chlorine analyzers were installed at each facility, along with chemical metering pumps to inject only the dosage of chlorine required for the specific site. Systems were designed to provide only the amount of sodium hypochlorite required for disinfection, while limiting and controlling the resulting THM levels.

One year pilot study to analyze the effectiveness of sodium silicate for corrosion control, followed by a system wide upscale for application.

Installation of sodium silicate and passive chlorite at four schools to address corrosion control.

Installation of sodium silicate treatment systems at two schools to address corrosion control.

Design of a new pump station and the rehabilitation of another in which chemical treatment using sodium hypochlorite was required for disinfection, sodium hydroxide for pH control and sodium fluoride for fluoridation.

Design of a new well station, booster pump station and elevated water storage facility where sodium hypochlorite chemical treatment was required for disinfection.

Design of chemical control and metering systems for sodium hypochlorite disinfection and sodium bisulfate for chorine neutralization. Monitoring systems for residual chorine and pH were also designed to control the injection process.

Engineering design for the conversion of a gas chlorine disinfection system to liquid chlorine, where we designed all the components for the conversion including tanks, chemical metering pumps, and controls.
