Treatment Improvements
Indianapolis Water and its operator, Veolia Water Indianapolis, are on the forefront of water research and technology, capitalizing on worldwide research into best management practices and developing new, innovative treatment techniques. Indianapolis Water customers benefit from the global resources available to Veolia and Indianapolis Water.
The White River North Treatment Plant
- The White River North Treatment Plant completed and placed into service a new three-million-gallon chlorine contact chamber. Like other 2001 surface water treatment plant improvements, this has helped lower trace concentrations of the by-products of disinfection, haloacetic acids and trihalomethanes, as reported on the 2002 Treated Water Quality Standings link. For example: the 2001 haloacetic acids average of 72 ppb was lowered to 37 ppb in 2002.
- The White River Treatment Plant chemical feed transition now includes liquid solutions to replace hazardous gases, thus eliminating the threat to the community from a potential release of chemicals into the air.
- The White River plant, which is Indianapolis Water's largest plant, was the last of the four remaining surface water treatment plants to complete the conversion from gaseous water treatment to liquid. Bleach solution is now used for disinfection in place of pressurized liquid chlorine gas.
- A residuals de-watering project at the White River treatment plant has helped reduce the solids load sent to the Belmont Advanced Wastewater Treatment Plant.
Additional Capital Improvements
- Refurbished the Tacoma Street dam to ensure the adequate flow of water to the Fall Creek treatment plant. The Fall Creek plant has a rated treatment capacity of 32 million gallons of water per day.
- Completed critical valve upgrades to filter structures at the White River and Fall Creek treatment plants. These plants accounted for 67 percent of the system's drinking water in 2007.
- Completed construction of a one-million-gallon storage tank to serve the northwest area of the service territory and a two-million-gallon tank with booster station on the city's west side.
- Began refurbishment and recoating of the 200,000 gallon wash water tank at the T.W. Moses treatment plant.
- Completed the rehabilitation of several production wells. Well water comprised approximately 19 percent of the system's finished water in 2007.
