Water Quality

Woodlands Mutual Water Company tests the drinking water quality for many constituents as required by State and Federal regulations. The frequency of the testing depends on the contaminate. The results of these tests are published in our Annual Consumer Confidence Report. These reports are mailed to each shareholder on or before July 1st of each year. Publications – Consumer Confidence Reports. To obtain a copy of any test result, please contact us at (805) 540-5208.

Groundwater is the sole source of water for the WMWC. This water is obtained through three wells located within the development. WMWC provides a safe and dependable supply of drinking water to our customers. WMWC currently meets all Drinking Water Standards as set forth in the California Safe Drinking Water Act and the regulations adopted by the California Department of Public Health (CDPH) for safety, taste and appearance.

WMWC adds chlorine to all groundwater delivered to customers to ensure the safety of the water supply. Chlorine is a disinfectant that effectively treats both bacteria and viruses, and is required by the State. Chlorine levels in the WMWC system are tested weekly to ensure appropriate levels are maintained. Chlorine is added to the water from our three wells before it is stored in our two 500,000 gallon tanks.

We do not add fluoride to our water.

Water Hardness:

Water hardness is a measure of the amount of certain dissolved minerals in the water, and typically it is comprised of dissolved calcium and magnesium. The moderate hardness present at the Woodlands is typical of local groundwater supplies and poses no health risk to customers. Groundwater supplies tend to have higher levels of dissolved materials when compared other sources such as streams and reservoirs, which are common sources for urban areas. Some customers who are accustomed to urban water supplies with low mineral content may perceive the water as lower quality, however all water quality within the development meets or exceeds State requirements.

Woodlands Mutual Water Company currently monitors the level of TDS in the water on a monthly basis. The results below are measured in mg/L.

Water hardness can be treated by removing all, or a portion of the hardness from drinking water. These include ion exchange (water softener) and reverse osmosis. It would not be economical to use either option for the entire Woodlands water supply, which also supplies a substantial amount of irrigation water. However, customers who are concerned about water hardness could install a private (residential) treatment system to serve their individual property.

There are restrictions on the type of water softening systems that can be installed out at the Woodlands. Water softeners that are self –regenerating discharge liquid waste with a high salt content. Their use will negatively impact the wastewater treatment plant. The use of self-regenerating water softeners is prohibited throughout the development as required in the Covenants, Conditions, and Restrictions (CC&R’s).

Please contact us to determine if your proposed water softener meets all necessary requirements!
