Reducing Water Supply Costs for the City of Brighton

Based on an analysis of historical production rates, groundwater levels, and available water rights, we developed recommendations for changing the balance of pumping between two well fields, prioritizing wells where water extraction and treatment required the least energy.


The City of Brighton provides water to about 10,100 accounts. About two-thirds of this supply is pumped from two well fields, which produce water that is treated using reverse osmosis (RO) and greensand filter systems. The balance of the water supply consists of treated water purchased from other sources. Honeywell is working with the City to improve its water supply and treatment systems and reduce utility costs. One important aspect of reducing overall water-supply costs is optimizing wellfield operations to minimize reliance on the energy-intensive RO treatment system.


  • Evaluated physical well capacities through analysis of pumping and drawdown records
  • Assessed demand and pumping during dry, average, and wet years
  • Determined water availability based on water rights and augmentation / replacement requirements
  • Prepared hydrographs comparing demand to water supplies from different available sources
  • Recommended changes in pumping schedules based on water rights, pumping and treatment capacity, available augmentation supplies, and replacement requirements
