Skills & Services

Benefit Cost Analysis Economic Impact Analysis Multicriteria Decision-Making Triple Bottom Line Analysis

One Water Econ helps water utilities make informed, cost-effective decisions about water supply and conservation. We apply a range of economic analysis methods to support utility planning, from evaluating supply alternatives and conservation program performance to projecting future demand and building the business case for water reuse. By quantifying the costs and benefits of current and emerging options, we help clients compare scenarios, understand demand dynamics, and design incentives and policies that promote sustainable and resilient water management.


  • Benefit-Cost Analysis of Water Supply Alternatives

    One Water Econ conducts benefit-cost analysis to support strategic water supply planning. We evaluate supply alternatives, including traditional and non-traditional options, by quantifying the financial, environmental, and broader community benefits. Our analysis helps utilities compare scenarios on equal footing, identify high-value investments, and align supply decisions with long-term resilience, affordability, and sustainability goals.

  • Demand Management & Forecasting

    One Water Econ performs rigorous economic modeling to evaluate the various factors that affect water use across customer types. We use these models to forecast future demands, inform water supply planning and rate design, and evaluate conservation program effectiveness.  We quantify the benefits and costs of conservation strategies and incentives, helping water suppliers integrate conservation and demand management strategies into their overall water supply portfolio.

  • Value of Water Supply Reliability

    One Water Econ values water supply reliability by assessing the economic and social impacts of water shortages, service disruptions, and drought-related constraints. We quantify the costs of reduced availability, such as landscape loss, business interruptions, and emergency response, and analyze customer preferences for outdoor watering, conservation behaviors, and service expectations. We help utilities understand how reliability affects customer satisfaction, willingness to pay, and long-term planning. These insights support investment decisions that reflect both system performance and community priorities.
