What is the Connection Between Rainwater and Stormwater?


rain-432770_1280Stormwater is rainwater that has not been collected and stored for future use, infiltrated or managed at the source. Rainwater, when not stored for future use or infiltrated on site, will flow into storm drains picking up toxins on the way and eventually will end up in our waterways.

The EPA has identified “stormwater as the greatest source of water pollution”.

With proper filtration and disinfection, the practice of rainwater collection for landscaping, toilet flushing, laundry, commercial and industrial use, along with potable use for single family residences, can minimize storm water runoff. The use of swales and rain gardens to lessen the effects of storm water from urban sprawl are helping reduce the effects of stormwater runoff.

According to the EPA “rainwater harvesting systems are recognized as a Low Impact Development (LID) technique for stormwater management.” As a result, many states, counties and cities have adopted and encourage rainwater collection. The EPA recognizes that the “effectiveness of a rainwater harvesting system for managing stormwater runoff depends on the presence of a consistent and reliable demand that can draw down the cisterns and ensure adequate volume for storm water retention.” A system that is sized properly by taking daily rainfall amounts into account, rather than yearly averages – and design that includes a full range of use during those peak events, or enough storage to minimize overflow, are going to be the most effective. 

Whether commercial or residential, rainwater collection, when sized properly and used regularly on a scale that lessens the overflow amount from the cistern, has the most positive effect on stormwater management.

Protecting Clean Water – Ditch the Myth

Protecting Clean Water - Ditch the Myth

Through education and research, RainBank is committed to sharing information of value to readers that can help them learn more about why it’s important to have clean water and how to design, build and maintain rainwater harvesting and collection systems for home and business.

The U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers seek to protect clean water and have proposed a rule to clarify protection for streams and wetlands under the Clean Water Act.

Here is a link to facts that were published in order to dispel apprehensions and misunderstandings about the proposed rule.  The site also points out that the proposed rule will help cut through red tape to make normal farming practices easier, while also ensuring that waters are clean for human health, communities, and the economy.
