Here in our islands, fresh water is a precious resource. Water distribution and treatment and wastewater collection, conveyance and treatment account for over 3% of Hawaii’s total energy consumption. In 2013, over 290 million kWh/year were used in these processes at a cost of more than $95 million dollars. It’s estimated that 10-20% energy savings can be achieved through energy efficiency. With the potential for savings of this magnitude, water and wastewater sectors represent one of the single largest savings opportunities in the state.

Our water distribution infrastructure is old and requires much maintenance. For the water and wastewater sector, while public health and safety is always the number one priority, pumping and treatment efficiency may not be at the forefront of daily activities. Hawaii Energy can assist your water or wastewater facility with energy-saving projects that can improve your systems without compromising public health and safety.
