Pentair Water Components Catalogue 2023

WELL WATER The groundwater beneath our feet makes up about 20% of the planet’s fresh water supply 1 , providing drinking water for over a third of the world’s population 2 . Private wells are a vital water provider in many countries – especially where surface water is scarce. They deliver a reliable and plentiful supply of water for home, industrial and agricultural use. Even in areas wheremainswater is plentiful, a privatewell can offer a guaranteedwater supply that, aswell as being natural and additive free, can be significantly cheaper than a publicmains service. In this brochure we offer some insight into the well water industry and explore how Pentair products can assure the supply and improve the quality of water from this source. MAIN TYPES OF WATER WELLS DUG WELLS Historically most wells were simply dug by hand, lined with stones, with a vessel dropped down to draw up water. They are prone to contamination and running dry during droughts. DRIVEN WELLS Still common, these involve a small-bore pipe being driven into the ground with a filter on the end. These only work to a limited depth and, like dug wells, are prone to contamination. DRILLED WELLS Today, most wells are drilled using large rotary bits that can go up to hundreds of metres deep. The borehole is lined with a casing and a pump is installed at the water level to drive the water to the surface. BENEFITS OF A PRIVATE WATER WELL • Uninterrupted, all-year supply of water • Constant water pressure • Reduced business overheads and water supply bills • Added value to property and business • A more natural product, free from additives • Reduced infrastructure and transport costs TREATMENT PROCESS FOR WELL WATER After thewater is pumped to the ground, additional components such as storage, pressure vessels, filtration, softening and disinfection can be added. The next page illustrates how Pentair products can enhance the water supply and improve the water quality in a typical drilled well.
