RAINWATER HARVESTING INTRODUCTION: We offer low-maintenance systems to collect, filter, store, and re-use rainwater for exterior or interior use in residential or commercial structures. In a typical installation, water from all of the downspouts of a building is piped to a central filter that separates solids. The filtered water is stored either in surface or underground storage tanks ranging from a few hundred gallons to many thousand gallons. Specialized pumps, control systems, and disinfection systems draw water from the storage tanks for irrigating landscapes, filling swimming pools or ponds, flushing toilets, and washing clothes. We can also supply rainwater systems capable of producing water suitable for showering or drinking.
