1303.1 While conservation efforts and other measures have been used as assumptions for the current 20-year drinking water demand forecast, which is significantly lower than demand was in 1995, important factors could affect future water availability. For example, the unpredictable effects of climate change, such as prolonged drought, could affect available water from the Potomac River, which is especially sensitive to changes in historic streamflow. One positive trend is the water conservation efforts of recent years. The 2015 ICPRB study found that the Washington, DC metropolitan area's efforts toward sustainable demand have been successful. While the area's population rose by approximately 18 percent from 1990 to 2015, its water demand has remained constant. The relatively consistent demand can be attributed to the falling per-household demand, which is forecasted to be reduced further by approximately 25 gallons per day between 2015 and 2040. The study also noted that supplier programs encouraging conservation were an important factor behind this trend.

1303.2 The following policy states the District's commitment to plan for the long-term adequacy of its water supply. It is supplemented by policies in the Environmental Protection Element on water conservation.

1303.3 Policy IN-1.1.1: Adequate Water Supply Provide a safe, adequate water supply, including in times of stress such as drought, to serve current and future District needs by working with other regional jurisdictions, USACE, and DC Water.
