Due to the heavy rainfall we have received, the nitrate concentrations have dipped below 10 mg/L in both rivers and remain below 10 mg/L in the Infiltration Gallery.
Residential lawn watering begins July 22!
The CIWW Technical Committee has voted to lift the ban on residential lawn watering beginning July 22. In order to manage demand, lawn watering must be conducted on the even/odd lawn watering schedule.

Even numbered addresses – Sunday, Wednesday, Friday

Odd numbered addresses – Tuesday, Thursday, Saturday

No watering on Monday
The goal of the phased approach is to allow lawn watering to begin again while reducing the odds of violating the nitrate standard. By gradually reintroducing demand into the system, we can effectively manage the water consumption and production levels. This is the quickest way to enable citizens to use automatic lawn sprinklers while still providing drinking water that meets all safe drinking water standards.

The first phase consists of residential lawn watering.

The second phase is commercial lawn watering – this includes businesses such as gas stations, business complexes, banks, malls, etc.

The third phase includes local governments including city, county, state, and school districts.
