The Brattle Group has extensive experience in the regulation of water utilities and the impact of environmental regulation on the water industry.

Our work includes economic analyses and testimony in environmental disputes, interstate water disputes, regulatory matters involving water and wastewater utilities, as well as analyses related to the interaction of energy and water. Related to the energy water nexus, we have provided economic analyses on the use of water in connection with fracking, the reliance of water in energy generation, and the use of energy in water production and distribution. In regulatory matters, we have provided testimony on site certification, cost of capital, and the regulatory treatments of infrastructure costs for water and wastewater utilities.

In addition to our consulting work, our experts have appeared before the U.S. House of Representatives and Senate staff to discuss economic analyses of water issues. We are also frequent speakers and publishers on issues in the water industry.


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

Cost of capital for water
For American Water subsidiaries in Arizona, California, New Mexico, Tennessee and West Virginia, Brattle has provided cost of capital testimony before the state regulatory commission. Such testimony has addressed the return on equity and capital structure that the utilities reasonably should be allowed to include in water and wastewater rates as well as the impact of regulatory initiatives such as decoupling, infrastructure recovery mechanisms, and regulatory lag on credit metrics and the cost of equity.
Recovery of water infrastructure costs
In connection with a water utility’s project to improve the capacity and reliability of its water distribution system, which would require customers to install pressure relief valves, Brattle surveyed common practices for the recovery of rebates that the utility would offer to customers and provided testimony on common practices for recovery of such costs.
Coastal Water Supply Project

On behalf of the Marina Coast Water District, Brattle undertook an economic analysis of the benefits of California-American Water Company’s Coastal Water Supply Project, which intended to resolve the long-term supply deficit in the Monterey water district.

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.
