Rainwater Pump Runs On The Sun

ITT Flow Control recently announced the development of their new, solar powered RainPerfect Water Pump, which takes harvested rainwater in a barrel and pumps it through devices like garden hoses and sprinklers. This way, the rainwater is recycled, and consumers can water their gardens and lawns or wash cars without putting strain on the public water supply.

The pump, which comes through ITT’s Rule Innovation brand, sits atop a conventional rain barrel, and can be hooked up to most garden hose fixtures. It pumps water with enough force to be used with a low-pressure sprinkler, the company says.

The pump is completely solar powered, coming with its own solar panel that powers a rechargeable nickel-metal hydride (NiMH) battery. The battery is capable of providing enough power to pump about 377 liters of water, the company says, which in most cases will be the full capacity of the barrel. The company calls the solar component especially useful during high-use periods in the summer, when homes and businesses run air conditioners.

ITT says it was inspired to develop the product after noting that residential water use spikes by an average 30 percent in the summer due to garden maintenance. Jeff Schopperle, ITT product manager, called using harvested rainwater, pumped by solar power, a good environmental and economic alternative to just turning on the usual spigot. “Water harvesting provides an alternative to using water supplied from utility companies and the RainPerfect pump provides the perfect solution to make water harvesting more accessible,” he said. “The pump enables people to optimize their usage of available natural resources in an easy and accessible way.”

    We purchased our RainPerfect rain barrel pump to pump the rain water out of our 60 gallon RainStation rain barrel. Works great! Got super fast shipping from http://www.aquabarrel.com.

    Great idea . Pls advise the cost for one system.nnCan anyone give a reasonably documented cost per KW/ hour comparing solar voltaic versus coal powered electricity.

    is the battery harmful to nature when it needs to be disposed of at a certain point?
