Water Hardness

The District does have hard water.

A good portion of the District's water is supplied by shallow alluvial aquifers. These aquifers expose water to natural underground calcium and magnesium deposits. This hardness can result in the buildup of white deposits called scale in cooking pots and coffee makers, and reduces the ability to make suds for washing.

The District performs many tests on our water supply - both regulatory (those you see in our annual Water Quality Report), and non-regulatory tests that include various compounds and/or constituents that may be present in our water. The attached information contains additional information regarding substances non-regulatory compounds. Non-Regulatory Compounds

In March 2021, the District began operations at the Ennis Water Softening Facility which softens the District water to a level of 7 grains per gallon.

Water hardness in the home can be managed with packaged water softeners or other softening devices. If you feel the need to install a water softener, shop around for the best price and choose a company that will stand behind their product.

If you currently have a water softener installed in your home, or if you are planning to purchase a water softening system in the future, please refer to the Softners and In-Home Treatment Page.
