Home Articles May is Water Awareness Month May is Water Awareness Month Posted: Wednesday, May 1, 2019 In recognition of Water Awareness Month, Mesa Water recommends the following helpful tips: Sweep (donāt spray) to clean outdoor areas, which saves 8-18 gallons per minute. Set mower blades to 3ā to encourage deeper root growth and saves 16-50 gallons per day. Use mulch in your planters to reduce evaporation and keep the soil cool, which saves 20-30 gallons per 1,000 sq. ft. each time you water.
