Water Protection

What you should know
Through careful construction and design, we are reducing water runoff and discharges and protecting streams, karst and other critical aspects of the environment.

Not only is Dominion Energy using less water at our facilities, we are taking measures to protect water amid construction activities.

Cove Point

We use groundwater for facility processes and human consumption at our Cove Point liquefied natural gas terminal in Maryland. The facility’s zero-discharge design is the first of its kind for an LNG facility. Process water is recycled and reused, not released to the environment.

Further, Cove Point was designed to protect water. Eleven manmade wetlands within the 131 acres in which we operate were designed to hold water and allow plants to absorb nutrients out of the water.

Atlantic Coast Pipeline

Atlantic Coast Pipeline route planning to ensure environmental safety and protection.

As we build the Atlantic Coast Pipeline, we're going above and beyond regulatory requirements to protect waterways along the route. Steps we are taking include:

  • More frequent and rigorous inspections to prevent runoff;
  • Stronger protections for sensitive streams; and
  • Protecting ridgelines during steep-slope construction.

We’ve adjusted the route on numerous occasions to avoid public drinking-water sources, private wells and natural springs. We’ve also adopted water-body crossing methods specifically designed to avoid affecting sensitive aquatic species such as mussels. We developed best-in-class construction and engineering techniques designed to protect karst geology. Dominion Energy, along with seven other energy companies, partnered with The Nature Conservancy (TNC) to develop best practices to minimize environmental impacts of pipeline construction in mountainous areas. A final report published in 2018, developed in close collaboration with TNC, is intended to serve as a catalyst for the pipeline industry to reduce the risks of landslides, slips, erosion and other environmental impacts on wildlife habitats and water quality.

Progress to Date

Freshwater Withdrawn to Produce Power
2000 and 2015-2018

We set a target to achieve a 50 percent reduction (from 2000 levels) in freshwater withdrawn per MW to generate electricity by 2030. Since 2000, we reduced the amount of freshwater withdrawn for each MW generated by 51 percent. As we’ve made considerable progress to date, we are evaluating our target as we integrate the SCANA operations, which were acquired through merger as of January 1, 2019.
