Taking Account for Your Water Usage

Home water usage significantly impacts the environment, contributing to: 

  • resource depletion
  • energy consumption, and 
  • potential pollution. 

Overuse can lead to decreased water availability, increased water treatment demands, and harm to aquatic ecosystems. Reducing water usage at home can help conserve resources and minimize negative environmental impacts.
