Part of the reason recycling water systems are not used as much is lack of knowledge. People on the survey in [clarification needed] showed that they were not likely to use recycled water for consumption due to fear. [30] However, those who are more educated on water conservation chose the "likely" option to using recycled water.

By reducing ground water pumping, the surface water supplies will be able to maintain their levels, as they recharge from direct precipitation, surface runoff, etc. It is recorded by the Environmental Protection Agency (EPA), that approximately 68 percent of water provided to communities in the United States comes from surface water.

The Roman Empire had indoor plumbing , meaning a system of aqueducts and pipes that terminated in homes and at public wells and fountains for people to use.
Developing sustainable water supply systems is a growing trend, because it serves people's long-term interests. [16] There are several ways to reuse and recycle the water, in order to achieve long-term sustainability, such as: Gray water re-use and treatment: gray water is wastewater coming from baths, showers, sinks and washbasins. If this ...
