Thank you for participating in the 2007 Irrigation Audit Program

Thank you for participating in the 2007 Irrigation Audit Program. This audit will help you make adjustments on water conservation, maintenance and/or management of your irrigation system. The following are my findings: Audit Summary: • Your system consists of 6 zones for the turf areas (zones 3-8) and two zones for drip system (zones 1 & 2.) • Several heads are tilted, low or need adjustment. • Two heads should be added for better coverage. • One head is stuck. • A few should have the throw adjusted. • Four should have the radius adjusted. All are indicated on the enclosed maps. Recommendations: • Tilted sprinkler heads indicated on the map need to be straightened. When heads are tilted just a few degrees it can seriously affect the radius. The top of the sprinkler head should be nearly at and parallel to grade. • Low heads should be raised enough so the spray does not hit the lawn directly in front of them. An easy way to tell if the sprinkler head is too low is by the presence of a “frog eye” pattern around the head. The blades of the grass will be pushed flat from the force of the water hitting them. When the spray cannot clear the plant material, it results in a broken spray pattern. Some areas will not receive adequate water and pooling occurs at the head. • The heads in need of adjustment should be rotated to cover the edges of the lawn and not spraying the hardscape or other unwanted areas. • Those that need the throw adjusted ...
