For centuries, people have relied on rainwater harvesting to supply
water for household, landscape, livestock, and agricultural uses.
Before the advent of large centralized water supply systems, rainwater
was collected from roofs and stored on site in tanks known as cisterns.
With the development of large, reliable water treatment and
distribution systems and more affordable well drilling equipment, rain
harvesting was all but forgotten, even though it offered a source of
pure, soft, low-sodium water.
A renewed interest in this
time-honored approach of collecting water has emerged in Texas and
elsewhere because of escalating environmental and economic costs of
providing water by centralized water systems or by well drilling. The
health benefits of rainwater, and potential cost savings associated
with rainwater collection systems have further spurred this interest.
