Increase Efficiency of Water Delivery System

Water Delivery System Efficiency is a Neutrality goal in the Cornell Climate Action Plan (CAP).



Increase the energy efficiency of the campus water delivery system through upgrading aging pumps and infrastructure.

Goal: Optimize the energy efficiency of the campus water treatment and delivery system.

Several infrastructure upgrades have been completed to increase the efficiency of the Cornell Water Filtration Plant. The electrical service entrance to the Water Filtration Plant was upgraded to improve efficiency in the plant’s pumping operation, and five pumps were replaced. The old pumps were either ON or OFF, pumping to their maximum capacity or off entirely. The new utilize variable frequency drives, so that plant personnel can adjust them to appropriate flow rates. Since the new pumps provide only the necessary energy to deliver water, they improve the overall efficiency of the water delivery system. Electrical savings will pay back the upfront costs of the pump replacement project.

In the next three to five years, additional improvements to the distribution system are planned, including replacement of aging pipes on North Campus. Such improvements will decrease the frictional losses in the system and remove potential vulnerabilities due to breakage or failure.

Next Steps

  • Track current electrical usage before and after upgrades to evaluate results.
