Raw Water from Lakes Arrowhead and Kickapoo are pumped into the City limits and stored at a Secondary Reservoir. The Secondary Reservoir retains 75 Million gallons of water within the City limits. At the Secondary Reservoir the water is blended from the two lakes to make treatment more uniform and a small amount of presedimentation takes place. This is the feed water source for all the conventional treatment plants. Raw water from Lake Kemp (Lake Diversion) is pumped via an irrigation ditch to a reservoir northwest of Wichita Falls. This water is the feed source for the Micro-Filtration/Reverse Osmosis plant.
Treatment with Chlorine Dioxide
The Raw Water is treated with Chlorine Dioxide in the transmission lines as it is taken to the plants. Chlorine dioxide is added to begin disinfection. It is one of the most powerful disinfectants available to eliminate waterborne pathogens. Chlorine Dioxide is also effective at removing Taste and Odors that may be present in the water.
The water from the Secondary Reservoir is received at two Treatment Facilities.
Once the water reaches the plants, the first process that begins is the Disinfection process. This is the most important process in drinking water treatment. This process removes pathogens that could potentially cause disease. The City of Wichita Falls utilizes Chloramines as its primary disinfectant for the conventional plant. Chloramines are formed by the reaction of Chlorine and Ammonia.
