Important information about water quality for businesses, restaurants, churches, and schools reopening following COVID-19 

ACWD provides high quality water to all customers. The water is disinfected before it’s delivered to you, but the water can accumulate in building pipes and become stagnant when businesses were closed or had limited operations during the COVD-19 Shelter-In-Place Order. Buildings and large service connections that shut down or significantly reduced water use have an increased risk of Legionella growth in pipes, refrigerators, water heaters, and/or onsite storage tanks, and an increased potential of leaching of lead and copper.

As the COVID-19 Shelter-in-Place Order is lifted and businesses reopen, it is important for managers and business owners to take action to ensure the water is safe to consume. Please reference the following guidance when reopening your business to learn how to remove stagnant water and prepare your building’s plumbing system for consumption.
