Commercial/Industrial Conservation
Our water is a finite resource and needs to be used wisely. Industrial, Commercial and Institutional (ICI) water can have a significant effect on our water demands. Businesses and industries use a vast amount of water and industrial water usage is extremely complex. Gwinnett recognizes that businesses and industries rely on the County's water resources and encourages them to conserve. A helpful way for commercial/industrial businesses to conserve water is to develop a water efficiency program. By developing a water efficiency program businesses can reduce cost and increase profitability through:

  • Water and sewer cost savings
  • Wastewater treatment cost savings
  • Energy savings

Gwinnett encourages water efficiency efforts such as commercial water audits, water efficiency assessments and training for industries, commercial businesses and institutions. The following are helpful tools for starting a water efficiency program.

Conservation Measures for New Development
To ensure that all new commercial buildings are built using water efficient plumbing fixtures, Gwinnett County has adopted the plumbing standards created by the 2010 Georgia Water Stewardship Act. The Water Stewardship Act calls on state agencies to amend the state plumbing code to require that high-efficiency fixtures be installed in all new construction granted a building permit after July 1, 2012. The new high-efficiency standards will also apply when purchasing fixtures for retrofit or renovation of existing properties. These standards tell builders and owners what type of plumbing fixtures they can place into new construction and how much water the new fixtures can use.  Below is a table that lists the current maximum water use rates and consumption standards for new construction. Added to the table are the average water usages before the current plumbing codes went into effect.
