Water and Energy Efficiency With Economic Impact
It has been estimated that 10-20% of current energy consumption in water and wastewater facilities can be reduced by energy efficiency 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 efficiency.
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 Efficiency Measures
- Raw water pumping
- High service pumps
- Backwash water pumps (filtration plants)
- Solar/wind 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
Electricity is required for water pumping and wastewater aeration – 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

Renewable Energy
- Full use of Digester Gas, when available, to generate heat or heat and power.
- Many water and wastewater treatment plants have found the installation of solar power to manage the risk of escalating and volatile power costs.
- Consideration of wind power, where appropriate.
- Waste heat recovery
- Waste water source heat pumps
