To improve water efficiency, please consider these tips:

  • Review water usage for your facility. By analyzing several years of water consumption data, patterns of use can be identified, and you might even discover evidence of a leak.

  • Upgrade to water efficient equipment and products or consider whether you have options to switch to a waterless or more water efficient process.

  • Re-think landscaping and stick to native or water-smart plants. Avoid planting grass in narrow strips along street or parking areas or along slopes since water will run into the street. Find a large variety of landscape options at

  • Communicate with your employees, contractors, customers or clients to let them know that water efficiency is a priority and shared responsibility in your organization.

  • Request a water survey from EPWater to assess your water use. Surveys are available if you meet minimum criteria on either irrigation or water consumption.

  • Double-check to make sure you are following the water efficiency requirements in the 2015 International Plumbing Codes (IPC), adopted by the City of El Paso.
