Water and Energy Efficiency With Economic Impact

Back River Treatment Plant

It has been estimated that 10-20% of current energy consumption in water and wastewater facilities can be reduced by energy conservation and operational changes. The addition of renewable energy sources can improve this even more. Johnson Controls has the ability to deliver meaningful energy reductions to water and wastewater facilities through our core competency and experience in energy conservation.


Water and wastewater utilities account for 30-40% of the electricity used by mid-sized cities. Make a huge dent in your community’s energy budget by improving your energy efficiency. Here are some examples of energy usage reduction measures:



Water Supply/Treatment/Distribution Energy Savings Measures

  • Raw water pumping
  • High service pumps 
  • Backwash water pumps (filtration plants)
  • Solar/wind/biomass renewable energy to power facility
  • Facility energy retrofits


Wastewater collection/treatment/reuse

  • Wastewater lift pumps
  • Aeration system improvements (diffusers, controls, blowers)
  • Digester gas to energy projects 
  • Pumping
  • Solar/wind/biomass renewable energy
  • Facility energy retrofits

The Energy and Water Nexus

Saving water saves energy

Water is required for electricity generation (in fact, 40% of the daily water withdrawals in this country are for electric generation). And electricity is required for water pumping and wastewater aerating – 30-40% of the electricity used by mid-sized cities is used to pump water through the distribution system and treat wastewater. Therefore, if we conserve water, we conserve the energy needed to pump and treat it.  By conserving water, we are conserving energy.

Contribute to saving of both energy and water by taking steps to be energy efficient in all facilities. Johnson Controls performs energy and water improvements that help you be sustainable and "green". Learn about funding water and energy projects.

Renewable energy

Fossil fuel sources are high water-demand fuels. Domestic fuel sources such as biofuels, synfuel from coal, and oil shale increase the demand for water to produce energy. An alternative solution is the use of low-water-demand renewable technologies to generate electric power and help reduce overall water demand significantly.

Water utilities can shift the dial when it comes to reducing greenhouse gases, reducing stress on aging distribution systems, and reducing peak electricity demands. How? Even a 5% reduction in utility-generated electricity via renewable energy can make a significant difference.
