Rain Water Storage

This is an interview with Steve Spratt, President of Home Preservation Services and Co-Founder of RainTechnologies, at the 2009 West Coast Green.

RainTube is a tube that is placed in gutters to address the common problem of gutter clogs as a result of collected debris. RainTube sits in the hollow space where debris usually builds up. Raintube is porous, so water can flow through it and reach the downspouts at the end of the gutter. This product ensures that your gutter will remain unclogged and do its job for at least a year. Raintube is manufactured out of high density polyethylene, derived from recycled plastic.

A new product that Rain Technologies debuted at this year's West Coast Green is RainSpace. This is an underground rainwater storage system that utilizes a collection of rainwater tubes to provide structural strength. The tubes are constructed of a slightly different design to allow for the pressure and weight from above. These tubes are completely enclosed with a pond liner, and this creates an enclosed space perfect for collecting and storing rainwater. This product can be installed in very shallow locations. For example, the display at the show was a 5 foot excavation, where the Rain Space product took up 3 feet of space, and 2 feet was backfill. This design allows for cars or heavy trucks to be parked right on top of it. 

This system stores a large amount of water. A 10'x10' ft system will hold 2500 gallons, a 10'x20' system (about the size of a single car driveway) will hold 5000 gallons, a 20'x20' system (which is the size of a 2 car driveway) will hold 10,000 gallons. This system is very inexpensive and easy to install, according to the company.
