Project
The Russellville Water Treatment Plant required an expansion in its disinfection capability to keep up with an increasing maximum day demand. The inherent risks and hazards associated with chlorine gas storage and use and the resulting insurance and risk management plan requirements led the utility to consider alternatives to gaseous chlorination.

Russellville City Corporation constructed a bulk sodium hypochlorite feed facility and abandoned the use and storage of chlorine gas. Certain challenges are inherent to the feed of sodium hypochlorite and include its high degradation potential at high concentrations and temperatures and the potential for off-gassing and subsequent air-binding of feed pumps. Garver designed the facilities with these challenges in mind and gave special attention to facilitate the ease of operation and maintenance.

Currently, the number of WTPs nation-wide that use sodium hypochlorite is very small. Garver successfully navigated the challenges of disinfecting with sodium hypochlorite and has produced a facility that will serve as benchmark to future designers.
