On Monday, May 20, 2019, ACWWA and our partner, Cottonwood Water and Sanitation District (CWSD), will start-up the reconverted Joint Water Purification Plant (JWPP). ACWWA and CWSD have been working to reconvert the plant’s treatment process to a Reverse Osmosis/Microfiltration blend. During the start-up phase, there is a possibility of discolored water due to the change in water flows and supplies. However, all water supplies are still expected to meet state and federal drinking water standards. As with any discolored water event, we ask customers to try running only the cold water at one faucet for about five minutes until the water runs clear. (Note that running the hot water instead of cold water pulls directly from the hot water heater and may delay or cause the water to not run clear.) If the water doesn’t clear up after five minutes, wait a few hours and try running only the cold water again. If the water is still discolored, please contact us so we can investigate the source of the discoloration. Even if you live in an apartment and/or don’t pay your water bill directly, it’s important to let us know about discolored water. Also, it is recommended that you don’t run your washing machine when there is any discoloration in the water to avoid the possibility of staining fabrics, especially whites. We will be monitoring the start-up process closely, and don’t anticipate any major issues. We will provide additional information here if needed. Please contact us at 303-790-4830 if you have any questions.
