Through the use of the latest water conservation equipment, proper system design, correct controller programming, consumer education and water audits we will keep your landscape green while using up to 40% less water than the average system. Water conservation is important. Hogan Irrigation, established in 1995 in Austin, Texas, has undergone a name change in 2010. We will begin operating under a new DBA as Going Green Irrigation. We feel that our name should say something about our underlying company philosophy, and Going Green Irrigation certainly does that.
