EXTRACTING WATER FROM A SURFACE SOURCE
There is something special about being able to extract water from a source in or bordering ones property. The joy can be short lived however if the correct procedures and equipment have not been installed from the outset. The last thing one needs is a water pump that continually needs attention, is too small for the required duty after two months or a unit that cannot develop the right pressure to deliver the required volume at the end point.
Procedures
In some places it is a statutory requirement that one applies for and is provided with permission in the form of a permit which entitles the holder to extract water from the source. If a river is bordering or running through ones property, the laws can be relatively strict depending on your country and region. It is in ones interest however to check with the local authority prior to investing in equipment.
Equipment
When extracting water from a surface source, one has the choice to use many types of pumps. The most common will be either submersible, a self primer or an end suction centrifugal type pump. Other types of pump units that are commonly used include, horizontal split casing, vertical turbine, dry well and many other centrifugal configurations. Another popular type of pump for raw water extraction is a progressive cavity pump and in some cases a diaphragm pump is used or even a piston pump. By far the most common water extraction principle is the centrigugal pump. |
