Deep well pumps
Deep well pumps are commonly known as borehole pumps
What is a deep well or borehole?
A deep well or borehole is a deep narrow well used to extract water out of the ground which is held in permeable rock. This water can be used in many different applications including domestic use, car washes, irrigation, industrial and commercial supply.
How does a borehole pump system work?
The system comprises a borehole or deep well pump, which lifts the water from the borehole into a tank. There will be a self-priming variable speed pump which draws the water from the tank and supplies it to the system needing the water such as a carwash. The whole system will be controlled by a panel that monitors the level of water in the tank and the borehole, which protects the pumps. In the unlikely event of the borehole yield being insufficient, the system will allow mains water to maintain the tank level ensuring constant availability of water.
What are the benefits of a having a borehole?
In today’s environmentally conscious world the borehole has an increasingly popular role, not only to reduce the environmental impact of a site, but reducing running costs for the operator.
The environmental benefits of the borehole system are:
- Reduced CO2 foot print per cubic meter of water
- No chemicals added to the water
- No loss of water through leaks in the pipe work infrastructure (20% of water is lost through leaking pipes according to the European Environment Agency)
- No impact on wildlife / river life (compared to surface water abstraction)
The cost benefits of the borehole system can be substantial. You are legally allowed to extract 20,000 litres of water per day without a licence or charge. Other than ongoing maintenance costs, this means free water.
What is the process when having a borehole pump system installed?
Dura Pump can project manage your entire borehole or deep well pump installation. The process we follow is:
- Hydrogeological survey – We will carry out a hydrogeological desk survey to obtain an understanding of the ground conditions where you require your borehole. This survey will give us an indication of the water depth and how deep we need to drill the borehole.
- Proposal – Once the survey is complete, we will put together our proposal for drilling the borehole and installing a complete pump system. At this point, we able to tailor our proposal to suit your exact requirements
- Drilling – On acceptance of the proposal, we will proceed to drill the borehole and line the inside of the borehole with necessary materials to filter the water and protect the borehole from collapsing.
- Pump system installation – Once the borehole is complete, we will install the pump, controls and necessary pipework.
- Commissioning – This is where we sign off the project. We will make the connection on to your existing system and test the borehole. On successful completion we can then hand the borehole over to the client.
- Maintenance – We highly recommend that your borehole is maintained on a 12-monthly basis, to ensure the system is working correctly, and to prevent any unnecessary damage. Dura Pump has a comprehensive service offering, Proserv, which can cover all of your pump maintenance requirements.
