Cross Connection Control Plan

Help protect our drinking water — take the 2-minute Cross-Connection Survey below
Required for many properties (new customers, added irrigation/pools, fire sprinklers, booster pumps, or auxiliary water sources).

💧 Cross-Connection Control (CCC) protects public health by preventing backflow—the reverse flow of water or other substances—into the UPUD water system.  A cross-connection is any actual or potential link between the public drinking water system and a source that could introduce contamination.  Common examples include private wells, irrigation systems, fire sprinklers with additives, swimming pools or spas with automatic fill devices, and booster pumps.

Why it Matters (for UPUD customers) 
  • Prevents contaminants from entering the community’s water
  • Required by California regulations and UPUD’s program
  • Quick for customers to complete, and helps us identify where backflow protection is needed

If our survey or inspection identifies a hazard, UPUD will guide you on the appropriate protection and testing—usually simple steps with annual checkups.

Who needs to complete the Survey? 

Please complete the survey if any of the following apply:

  • You are a new UPUD customer or your property use changed (added irrigation, fire sprinklers, pool/spa, business on site, booster pump, etc.)
  • You have or plan to install an auxiliary water source (private well, surface water, etc)
  • You received a notice from UPUD requesting an update
    Residential, commercial, and agricultural customers may all be subject to CCC requirements
💡 Did you know? Even a simple garden hose can create a cross-connection if submerged in standing water or attached to a chemical sprayer. That’s why UPUD checks and documents backflow protection through this quick survey.

đŸ§© What Happens After You Submit

Here’s what to expect:

  1. You complete the online survey (2 minutes).
  2. UPUD reviews your information within 10 business days.
  3. If your property may require a backflow prevention device or inspection, staff will contact you.
  4. You’ll receive written confirmation once your record is up-to-date.

Your participation helps UPUD maintain a safe and compliant water system for all customers.
