Riverside County has multiple water districts serving different communities, and understanding who supplies your water — and how to contact them for billing questions, outages, and conservation programs — is essential for every homeowner. Davis Plumbing and Heating Inc. serves customers across all Riverside County water districts and knows the specific water quality challenges in each service area.

How to Read Your Water Meter
Your water meter is typically in a covered box near the street. Most Riverside County meters have a digital display or a round sweep dial. The reading in hundred cubic feet (CCF) multiplied by 748 gives gallons. One CCF = 748 gallons. Use this to track your daily usage or detect hidden leaks.
Water Quality Reports
Each water district publishes an annual Consumer Confidence Report (CCR) showing your water’s contaminant levels, hardness, and treatment methods. These are usually available on each district’s website. Davis Plumbing reviews these reports to inform our water treatment recommendations for each service area.
