| Deepwell Dewatering Bore scheme |
1.The area for installing deep sump well will be
marked by surveyor and the area will be checked for existing underground
utilities.
2.
The sump well be installed into the ground using water jet. If the strata are
hard to penetrate, then suitable bore holes will be made for installing the
deep well sump.
3.
After the hole is drilled, an Ø200mm PVC perforated pipe is installed into the
drilled hole surrounded with 3/8 3/16 aggregate filter materials to prevent the
fines entering the system.
4.
The submersible pump will be installed into the perforated pipe. The pump is
connected to the electrical power generator/ EB.
5.
The outlet of these well pumps are connected to the vertical pipes, which is
connected to the suction hose.
6.
The suction hose transfers the water to the sand settling tank. The silts settled in the
tanks
will be removed and dumped in an approved
location.
7.
The pumps will be operated until the work is completed. On completion of all
dewatering activities the bore holes will be filled with suitable approved
material.
8. Water levels
will be checked and recorded regularly to derive the drawdown.
