SAWS will provide interested home owners with a free one hour irrigation consultation.  A SAWS licensed irrigator will run your system.  They will tell you your actual usage water for each zone.  At the conclusion of the consult SAWS will suggest improvements and provide you with a Custom rebate to help defray cost if you choose to make changes.  The average saving for residents following recommendations is 2000 gallons a month.  For more information, go to www.SAWS.org.
