Installing a Pump in a Sand Spear

Sand Spear points are a type of bore used in shallow (less than 6m depth) unconfined aquifers.

Shallow installations are usually used for delivering low quantities of water for watering a garden for example. Sand Spears come in both stainless steel V-wire or PVC. The design of the Stainless steel V- wire has some definite advantages over the PVC type for example:

  • V-wires have a non-clogging surface
  • They can cover a large open area
  • Have a low pressure drop
  • Are Hydraulic efficient
  • They have high flow rates
  • V-wire has mechanical strength
  • It’s easy to clean
  • It has a close slot tolerance
  • Has a lower entrance velocity
  • And they are used for better well development

For low-yield requirements a PVC sand spear may do the trick. It’s less expensive, non-corrosive, light weight and can easily be manufactured to suit your specific requirements.
