The TWDB’s Texas Rain Catcher Award recognizes excellence in the application of rainwater harvesting systems in Texas, promotes rainwater harvesting technology, and educates the public on this important water-saving practice.
About the Rainwater Harvesting System
Innovative Water Solutions LLC designed and installed a 55,200 gallon rainwater harvesting system for Anodamine, Inc. which is located in Lago Vista, Texas. The rainwater harvesting system will collect rainwater from 12,000 sf of roof area. The design of the roof along with the location of the cisterns created an opportunity to harvest from nearly the entire roof area of the building. This collection area provides a potential to collect 230,000 gallons of rainwater during an average year of rainfall. The rainwater storage system consists of six (6) 9,200 gallon Contain brand corrugated metal cisterns with internal poly liners. The rainwater is collected from the larger portion of the roof through “dry” connections while a “wet” connection is used to collect rainwater from a downspout on another portion of the roof.
The system employs an automated first-flush diversion system which allows for the first rainwater from the roof to be wasted. Once a set intensity of rainfall is achieved or once a certain amount of rainfall, both measured with an optical sensor, and is reached, the automated system closes the first-flush diversion valves. This automated first-flush system will produce higher-quality harvested rainwater by allowing the rainwater that carries the accumulated dust, pollen, and bird droppings to be wasted.
At this point, the rainwater will flow into the cisterns through inlet filter baskets. The six cisterns are interconnected in series with a 4” pipe which allows the cisterns to all share volume and fill equally. A pump and filter system will pull the rainwater from the equalization pipe to be used to supply water for the industrial processes inside the factory.
The factory is connected to Lago Vista water utility for the factory’s potable water supply. With this rainwater harvesting system, they will be able to use rainwater for their industrial processes rather than using municipally treated water. By reducing their municipally treated water use, they are helping to preserve the local water supply. In addition, this system reduces the stormwater runoff from the building and thus the property, providing local stormwater management benefits.
This system is projected to pay for itself in 7 years using a 3% annual increase in water/wastewater rates by the Lago Vista water utility.
