The Brattle Group assists clients in both the public and private sectors to manage the economic and regulatory challenges associated with water resource litigation, water quality, and the development of water resource policy. We provide analyses on the econometric estimation of water demand, groundwater storage and management, rate setting, cost of capital, and the economic impact of environmental regulation on water utilities.

Our experts are knowledgeable in the areas of water conservation, resource planning, water supply reliability, interstate water disputes, agricultural water use, and water-energy connections. We have been studying the energy/water nexus with particular attention to the role of renewable energy facilities and water efficiency.


Below is a list of representative engagements for our Water Resources practice.

Interstate water disputes
As part of a US Supreme Court matter of original jurisdiction, Brattle conducted a range of analyses to assess the economic value of water in a river basin subject to an interstate dispute. Brattle evaluated the costs and benefits of a host of urban and agricultural water conservation measures to highlight opportunities for an economically reasonable resolution.
Forecasting urban water demand
Brattle led a data collection and modeling effort to forecast the diverse set of local water demands that exist in different parts of California. The work represented an important information source for understanding the spatial and temporal patterns of water demand which can be used to identify water supply needs. The findings of the study were also used to estimate the responsiveness of demand to changes in water rates, which can be used to understand the impacts of projected rate schedules and to infer the value of water to users.
