In the southwest, irrigation of landscapes accounts for approximately 50% of total domestic water-use in urban areas. Based on some surveys, more than half of this water could be conserved without adversely affecting the quality of existing landscapes if irrigations were carefully scheduled to satisfy plant needs (ET for acceptable quality.)

Irrigation Auditing

New Mexico Office of the State Engineer provides A Water Conservation Guide for Public Utilities that incorporates a residential landscape audit section on pages 104-110 of the PDF file. The landscape audit can be conducted by a certified landscape auditor or a homeowner with knowledge of irrigation systems. The manual describes how to evaluate sprinkler irrigation system performance, explains how to efficiently schedule irrigation on turfgrass, and determine annual savings of water and money.

Turfgrass Management

In New Mexico, turfgrass is comprised of industrial and institutional grounds, home lawns, and recreational spaces. Quality water-wise turf provides site beautification, recreation, and erosion control.

Water Requirements

A study conducted at the Agricultural Science Center at Farmington, from 1998-2001, identified the water requirements of some cool and warm season turfgrasses. These findings resulted in the formulation of consumptive-use curves and crop coefficients that can be used to efficiently schedule irrigations on turfgrass.
