Dams are at all-time lows; municipal water costs are rising and people are getting angry. There has never been a better time to examine alternative water sources than right now. Drilling a borehole and becoming self-sustainable might be an option worth considering.
Here's what you need to know about the process of drilling boreholes:
#1 Borehole siting
Determining where the water is and how to reach it, is the first step when it comes to drilling boreholes. It is crucial to employ professionals for this task to avoid drilling into natural hazards or pipelines and cables.
#2 Drilling and Construction
The next step is to commence with the drilling. Special machinery is used to drill deep into the earth's surface. While the depth of an average borehole ranges between 60m - 80m, it can vary greatly from one borehole to another. Construction comes next in the form of steel casing to reinforce the borehole.
#3 Yield testing
Yield testing is done to determine the balance between the greatest amount of water that can be yielded from the borehole and the amount of water that flows back from the neighbouring groundwater source. In order to do yield testing, an aquifer test is carried out. A test pump is installed and water is pumped for a fixed time and set of variables to access the water level in the borehole.
#4 Pump and filter installation
Once the yield testing is done, you'll be advised on the pump you need. The type of pump system will depend largely on your intended use of your new borehole. If your domestic borehole will be used for drinking water, you'll need a filtration system to get rid of contaminants from your water supply.
If you are interested in drilling a borehole on your property, get in touch with one of the experts at Enviro Boreholes. With over 10-year experience in the industry, you can be sure to receive professional and advice and great service.
- Purpose of borehole - will the water be used for irrigation, domestic usage or to fill up a reserve tank.
- Flow rate - which means the amount of water to be moved and the pressure needed to get it there
- Distance the water needs to travel - from under the ground to the top of the borehole, and from the borehole to your tap
- Refill rate - the water level in your borehole will drop when pumping water and will refill when it rains
It is crucial to service and maintain your borehole and pump frequently to have the best return on investment as well as your own private source of running water year-round. By following these easy steps, you can protect your system and water source.
If you are considering becoming self-sufficient, have a look at the considerations below to find out if you too could benefit from installing a borehole on your property.
1. Always use a professional
Whether you are investing in a borehole or maintaining an existing one, it is vital to use an expert in the field. Never attempt to service your own borehole as you will risk contaminating your water source. At Enviro Boreholes, we have ten years’ experience and have drilled over 1000 boreholes in the domestic, commercial and agricultural fields.
2. Don't store or mix chemicals near your borehole
Hazardous chemicals like paint, pesticides and fertilizer can contaminate your water source. A simple spill could quickly leak into the well. Don't ever pour pesticides. Also, make sure you check the borehole cover regularly and be careful when working or mowing around the borehole to avoid damage to the casing.
3. Sanitize your borehole
Anytime repairs are done, your borehole should be sanitized. It's also advised to re-test your water pH-balance to make sure the issue has been fixed.
4. Protect your borehole with a tight-fitting head cap
To protect your borehole, you should ensure it is sealed properly. If not sealed properly with a tight-fitting head cap, it will be easy for undesirables like insects and mice to enter the borehole or holding tank.
Unfortunately, the quality of your water resource can be affected over time, and it is essential to monitor your water quality frequently against bacterial contamination. A simple SANS-241 test should be done at least once per year. It is recommended to seal abandoned boreholes since they can contaminate your groundwater source.
