Why Arvada Requires Annual Backflow Testing

The City of Arvada’s cross-connection control program requires all backflow prevention assemblies to be inspected and tested every year. Colorado CDPHE Regulation 11, Section 11.39 backs this requirement statewide, mandating that public water suppliers require annual testing on any service connection that poses a health risk to the drinking water system. There are no exemptions.

Irrigation systems are a primary reason this regulation exists. Your sprinkler system draws from the potable water supply and is directly exposed to pesticides, animal waste, and fertilizer in the soil. If water pressure drops during a main break or a high-demand period, that landscape-side contamination can reverse into your drinking water. Annual testing helps confirm your backflow device is working before that situation arises. Because devices must be tested while the system is active and pressurized, turning your irrigation system on in the spring is the right window to get it done.

What Our Backflow Testing Covers

Irrigation systems use one of two device types depending on the installation: a pressure vacuum breaker (PVB) or a reduced pressure zone valve (RPZ). Each functions differently and requires its own testing protocol. Our certified technicians inspect all components of your backflow device system regardless of which type is installed on your property.

We approach backflow testing as annual maintenance of your irrigation system, not an isolated compliance task, so we’re evaluating your system’s overall health at the same time. Backflow compliance and water-efficient irrigation aren’t separate concerns. A well-maintained system supports both.

How Backflow Happens & Why Irrigation Systems Are High Risk

Backflow is the undesired reversal of water flow into the potable water supply. Under normal conditions, water pressure moves in one direction: from the municipal supply into your property. When that pressure drops suddenly during a water main break, a nearby fire hydrant activation, or a period of peak demand, the flow can reverse. Anything on the irrigation side of the connection gets pulled back into the supply line.

Irrigation systems are particularly high risk because they’re designed to feed vegetation. The soil your sprinkler heads sit in contains pesticides, animal waste, and fertilizer at varying concentrations throughout the season. A backflow event can pull those contaminants into the water supply. Common signs that something may have already occurred include a drop in water pressure and discolored water, though contamination isn’t always visible.

A backflow preventer helps stop this from happening. The two device types used on irrigation systems work differently:

Pressure vacuum breaker (PVB): Installed above ground, typically upstream of the irrigation zone valves. It helps prevent backflow by opening an air vent when supply pressure drops, breaking the siphon before reverse flow can occur.
Reduced pressure zone valve (RPZ): Provides a higher level of protection and is typically required where the contamination risk is greater. It uses two check valves and a relief valve to maintain a pressure differential that helps prevent backflow in either direction.

Arvada Water Compliance: What Property Owners Should Know

The City of Arvada maintains a registered list of certified testers and requires annual testing results as part of Arvada Water compliance. Colorado CDPHE Regulation 11.39 governs this requirement statewide, and there are no grandfathering provisions. If your property has an irrigation system connected to the municipal supply, a backflow prevention assembly is required and must be tested every year. Non-compliance can result in a compliance notice from Arvada Water, and unresolved violations may lead to service interruption.

Colorado HB25-1077 & Certified Technician Requirements

Colorado HB25-1077, signed into law on March 28, 2025, and effective July 1, 2025, allows certified cross-connection control technicians to inspect, test, and repair backflow prevention devices without requiring a licensed irrigation professional’s license. The law also requires a credential tag identifying the technician and the work performed to be affixed to the device after each service visit, creating a clear documentation record on the device itself.

Testing results for irrigation assemblies are typically submitted to the local water authority. When you schedule with us, ask about documentation handling so you have a clear record for your property file.
