The ACSA provides irrigation service to our residential and commercial customers. There are two designs of irrigation systems currently in our system:

1. Auxiliary Meter Systems. All new irrigation systems as of January 1, 2006 must be of this design. Irrigation water is served by a separate tap on the ACSA water main. Irrigation water usage is measured by a separate (auxiliary) meter similar to the main water meter serving the house or facility. There are no sewer charges on the irrigation water.

Regardless of whether irrigation water is used during the season, the annual testing of the backflow prevention assembly must be performed. If you own a property with an auxiliary meter irrigation system, and are considering “abandoning” the system, click on the link to the left for further information.

2. Exclusion Meter Systems. With this design, the plumbing of the irrigation system branches off the private water service line feeding the house or facility. A second meter, called an exclusion meter, measures the amount of irrigation water used. There are no sewer charges on the irrigation water.

Beginning January 1, 2006, the ACSA Rules and Regulations were modified to no longer allow the installation of exclusion meter systems.  The ACSA is currently in the midst of a multi-year program to replace all exclusion meters with auxiliary meters.  Property owners continuing to properly maintain their irrigation system, including the annual testing of the backflow prevention assembly, even if irrigation water is not used for the season, are able to continue using their exclusion meter until the replacement work is performed by the ACSA.
