Lake Water Treatment
At the Grapevine and TRA water treatment plants, the lake water goes through several treatment processes where chemicals such as chlorine, ozone, alum, fluoride, caustic soda, ammonia, potassium permanganate and polymer are added to purify the water. After the water is purified, it is pumped into your homes through more than 280 miles of distribution pipelines.
