Sanitation District No. 1's main wastewater treatment facility, the Dry Creek Wastewater Treatment Plant, treats an average of 35 million gallons of wastewater per day (MGD). Gaseous chlorine is currently utilized at the treatment facility for odor control and disinfection. Because of the hazardous nature of this product, two years ago the District began planning for the transition to sodium hypochlorite at the Dry Creek facility. Studies show that this transition would cost the District an estimated 3.8 million. Studies have also revealed that the estimated amount of sodium hypochlorite that would be necessary to replace the amount of gaseous chlorine currently being utilized is more than two times the amount that is typically needed for a 35 MGD plant.

In order to reduce the amount of sodium hypochlorite needed at the plant and minimize the estimated costs, the District chose to take a holistic approach to reducing the amount of hydrogen sulfide (H2S) produced within the collection system. Studies were conducted throughout the District's collection system to pinpoint locations of high H2S production. One of the identified problem areas was in the Taylorsport collection system located in northern Boone County.

The Taylorsport Pump Station transports over three million gallons of wastewater per day to the Dry Creek Wastewater Treatment Plant. The District has taken many steps to reduce the amount of H2S within this system including the installation of biofilters and the addition of chemical treatment. Air monitoring results following these improvements show a major reduction in the production of airborne H2S. Through this process, the District found that taking a holistic approach by evaluating the entire drainage system increases the effectiveness of controlling odors and reducing the concentration of H2S.
