Important Irrigation Installation Update

As of July 1, 2009 all irrigation design, construction and maintenance exceeding $2500 must be performed by a licensed irrigation contractor. 

All irrigation systems installed after July 1, 2009 must be connected to a separate irrigation meter.  Updates will be posted here.

The key to protecting your safety is having proper backflow measures in place.

General Information about Backflow Prevention
People often think water travels in only one direction through the distribution system, but under certain pressure conditions, water can actually travel backwards. If a customer's water supply line is connected to a substance not fit for drinking and the line is unprotected, then the unfit substance could travel backwards through the water distribution system. This is known as backflow.

Consider a hose submerged in a bucket of garden chemicals. If the water pressure in your area becomes lower than normal, the chemicals in the bucket can flow backwards through the hose and into your drinking water supply.
