Developing Tool
& Hand Pump
Drilling methods
and Installation
of a sand spear
Developing Tool
Developing Tool
& Hand Pump
Installation Completed
Now that you have completed the
installation of your sand spear system.
There are two things to do.
One is to develop it and the other is to
be able to pump water to the surface,
for you to use
You are now technically
ready to Install your pump
Just Not Yet
Installation Completed
You may need to Develop
Your Bore or Sandspear
But First
Your Bore or Sandspear will work
without developing it.
Most Bore wells are developed
The majority of Sandspears
installations are not
Do I have to?
Developing
By developing the bore it flushes the
fine sand and any from the aquifer
surrounding the screen
Developing
Increases Production Capacity
Stabilizers formation
Prevents pumping of sand and
damage to pump
Protects check valve seats
Theory
This is similar to unblocking a drain with a
rubber plunger, when the plunger is push,
it pushes pressures out into the aquifer,
and then when pulled up it sucks in the
fines.
And then they are removed
Same action as a piston pump, up down
Equipment Used
Air Compressor
Surge Block
High pressure water
Water Pump
1. Push it down the hole
2. And pull back up
3. Has Non-return Valve
4. Seals against riser
By Hand
Air Compressor
Air is pushed down by a tube that is in
the Riser to the very bottom of screen
Air then pushes the water up to the
top.
Creates a suction effect on aquifer and
sucks out fines
Air is turned off and then back on
Water Pressure
Similar to the air
method, except a high
pressure water system is
used
Pump Time
Now that you have created a excellent
efficient borewell or Sandspear system, its
time to connect pump
Pump Time
Now that you have created a excellent
efficient borewell or Sandspear system, its
time to connect pump
Suit to purpose
Decide on drilling method
Screen to match Gravel
Check on Council regulations
Choice the best position
Do your homework first
When purchasing or Install your Sand Spear…
Mud
Soil
Driving of PVC Screens
Deeper than 3M
Air leaks
Screen above the Aquifer
And try to avoid…
