Water Conservation Efforts

The Problem

The U.S. Bureau of Reclamation announced an emergency shortage declaration for Lake Mead and the lower Colorado River Basin on August 16, 2021. This was the first shortage declaration in its history. This action calls for a reduction of the amount of water Southern Nevada is allowed to draw from the lake. Southern Nevada's water allocation was reduced by seven billion gallons – that’s enough water to serve 45,000 homes – effective in January 2022.  And in August 2022, the federal government announced a tier two water reduction, further limiting the amount of water we can withdraw from Lake Mead, effective in January 2023.

  • Master Valve added to Xeriscape Park (Updated Sept. 2022)

  • Continuous monitoring and adjusting of sprinklers (Updated Sept. 2022)
  • Water budgeted for golf courses cut from 6.3 acre-feet per irrigated acre to 4.0 acre-feet per irrigated acre throughout Southern Nevada
  • Water budgeted based upon acre-feet of water for each acre originally irrigated
  • Acreage includes lakes and ponds on the course
  • Acreage remains fixed - incentive for courses to convert to water efficient landscaping


  • Developing new landscape requirements for new development and guidance for parkway landscaping
  • Planting/cross-seeding more drought-resistant grass in parks/facilities
  • Updated irrigation systems to make sure the water is used exactly where and when needed
  • City staff is working with Southern Nevada Water Authority to replace non-functional grass in City parks

Public Information

  • Campaign will be launched to further educate the public
  • This is a process – all efforts will be moving forward to meet our goals
  • Sharing information via Utility Bill insert, YouTube, BCTV, social media platforms, newspaper articles, City website and more


  • 40-percent of American Rescue Plan Act dollars for water conservation and wastewater programs (more than $10 million)
  • City Council and City staff are working with the Southern Nevada Water Authority (SNWA) on efforts to reuse wastewater in a more sustainable way and reduce water usage throughout the community

HISTORY: Since 1965, Boulder City has processed wastewater by sending it through a bar screen and grit removal system to remove solid waste. It is then released into evaporation ponds or sold for dust control. This wastewater is called "effluent." Currently, between 1.2 million and 1.5 million gallons of effluent is released daily into the evaporation ponds. In March 2023, City Council requested SNWA complete feasibility studies on Option 2 and Option 3, detailed here:

Feasibility studies should be complete in 2024. If you have questions, email staff at water@bcnv.org

SNWA Water Smart Landscape Rebates

Residents can take part in the Southern Nevada Water Authority rebate program to replace non-functional grass with desert landscaping. Residential properties, businesses, HOAs and multifamily properties are eligible and can get $3 per square foot of grass removed and replaced with desert landscaping. Both SNWA and Boulder City offer rebate programs for smart controllers. These devices turn off your sprinkler system when it rains to prevent unnecessary overwatering of turf.
