How Deep Does Your Borehole in Zimbabwe Need To Be - Consider These 5 Thing!

If you are a homeowner new to the drilling of residential Boreholes in Zimbabwe, you may find many aspects of this process confusing or even a little daunting. 

This is understandable, as modern Borehole Drilling involves difficult calculations, scientific elements, and industry terminology. But by learning a little about the basic aspects, you will be a savvy property owner and have confidence in your decisions regarding the Borehole. 

Consider one of the most common questions posed by property owners: how deep should your Borehole? 

The answer varies significantly, and it affects everything from the cost of the Borehole to how long it may last. To help you answer this question for your own situation, here are five of the biggest factors that will determine the Borehole's depth.

1. Other Local Borehole: One of the best places to start finding the right depth for a Borehole is to look at the depths of existing Boreholes in the region. General geography — particularly the rock layers and depth of aquifers in the area — are spread out over a large physical region, so the positions of other successful Boreholes can serve as a rough idea of what yours might need.

For instance, your contractor might begin with the knowledge that an average Boreholein your part of the country is about 300 feet deep. In addition, though, if your specific area is affected by increasing or historic droughts, they might know that you're likely to need a deeper than average Borehole.

2. Your Property Characteristics: Of course, surrounding Borehole can only provide general information about highs and lows and average numbers. The contractor will then need to assess your specific property to see how it measures up to other situations. For example, if the rock formations below your property don't allow the water to flow in sufficient quantity, your particular Borehole may need to be larger in diameter to compensate. 

3. State Regulations: Boreholes are overseen by state agencies, so the drilling company will need to follow any applicable rules. Rules about such things as the diameter of the Borehole versus the necessary gallons will inform how large and deep yours might need to be. Similarly, the length of casing required to be in bedrock in your state could affect how deep it needs to go. 

4. Water Quality: Just because a drill reaches some water doesn't necessarily mean that this is good quality water. If the water source is too close to the surface, you could see bacterial contamination and other quality problems from the groundwater. However, a Borehole that is deeper risks an increase in hard water that must go through added layers of rocky minerals before reaching your home. 

5. Water Table Action: Like most water sources, water tables vary over time. They rise and fall with the seasons — generally filling up in wet times and lowering in dry seasons. So your Borehole would need to be deep enough to provide water access both when the table is high and at the lowest point expected. The drilling service may study the area's drought history to help find out what those lowest points might have been. 

Clearly, many elements go into deciding on the right depth for each individual Borehole. An experienced drilling service will examine everything from the region's history with Boreholes to seasonal variations to drought history to the type of rock on your property. As a result, you can rely on their drilling to produce a Borehole that will serve your family's needs for many years to come.
