Water Efficiency & Reuse
◼ The first question to ask: “Is water efficiency the
most important issue I need to address with
regard to water use?”
➢ Wastewater treatment
➢ Stormwater management
➢ Watershed and community risks
➢ Supply reliability (when sourcing water from a
municipality)
➢ Supply sustainability (when souring water directly
from the environment)

Water Efficiency & Reuse
◼ Lessons learned as you advance your program:
◼ Where are you in the maturity continuum?
◼ How do you benchmark and find best practices?
◼ When to set an improvement goal?
◼ Is zero-discharge really achievable?
◼ Calculate the total cost of water including embedded
energy, labor, chemicals to maximize ROI evaluations
◼ Anticipate and overcome the hurdles to realize identified
savings:
➢ Competition for capital
➢ Limited project management capacity
➢ Need for O&M plans, new process description, training
➢ Behavior change
➢ Uncertainties with new technologies
