Water Conservation

Thank you to all Del-Co customers for your assistance with following the watering restrictions this past season. In mid-July, Del-Co's raw water supply had reached critical levels due to the extreme heat and drought conditions. Fortunately, the restrictions and more reasonable weather patterns reduced the watering demand allowing Del-Co to refill the primary raw water storage reservoirs. Therefore, as of October 8, 2012, the watering restrictions are restored to the routine three days per week.
  • Odd address: Sprinkling / Watering permitted Tuesday, Thursday, and Saturday
  • Even address: Sprinkling / Watering permitted Wednesday, Friday, and Sunday

Protecting Your Water

Backflow prevention and cross-connection control are unfamiliar terms to many of us; however, they should be of great concern. The backflow of chemicals or contaminated water into the public water system is responsible for many illnesses and deaths every year in the United States.
