Borehole Equiping
RANA LTD Borehole equipping is the crucial final stage of making a drilled well functional, involving the installation of a pump, pipes, control systems, and power supply (like solar or grid) to extract and distribute water efficiently for domestic, irrigation, or industrial use, requiring essential steps like test pumping to determine yield and selecting appropriate components for sustainability and performance.
Essential Pre-Equipping Steps:
Test Pumping: Determines the borehole’s yield (litres/hour), drawdown, and recovery rate.
Water Quality Analysis: Checks for contaminants to ensure safety.
Borehole Completion Record (BCR): Official document from water authorities with key data.
Rana Key Components Installed:
1. Submersible Pump:
Placed in the borehole, chosen based on yield and depth (Total Dynamic Head).
2. Piping:
Drop pipes (UPVC/galvanized) carry water up, connected to distribution pipes.
3. Control Panel/invertor:
Manages the pump, with features like overload protection, level controls, and auto/manual switches.
4. Power Source:
Solar panels (often with inverters) are popular for cost savings, or grid/generator power.
5. Cables:
Waterproof submersible cables connect the pump to the control panel.
6. Water Storage:
Tanks and stands for storage and gravity feed.
7. Accessories:
Sensors, junction boxes, earthing, non-return valves, and well covers.
The Process:
1. Development & Testing:
Clean the borehole and conduct yield tests.
2. Design:
Engineer selects components (pump, solar array size) based on test results.
3. Installation:
Mobilize equipment, install pump, pipes, cables, and power system.
4. Commissioning:
Test the system thoroughly, record parameters, and provide manuals.
