Whether you are drilling a new borehole or rehabilitating an old one, it is crucial to use the expertise of a skilled water surveyor. Over time many old wells collapse and are not any longer viable. You can risk losing all your gear should you install the pump before doing a proper evaluation of the borehole.

Additionally, it is vital that you perform a yield test to determine the amount of water in your well. As a result, it's possible to make the appropriate pump choice for your borehole.

Why is it important to do yield testing?

  • To determine borehole potential - To calculate the sustainable yield and hydraulic functionality of boreholes for water supplies.
  • To identify aquifer potential - To assess the hydraulic characteristics of the aquifer to discover the groundwater sources.

The water yield may differ based on the season, the number of new boreholes nearby, the variations in the annual rainfall as well as adverse environmental effects of high transpiration resulting from the planting of large quantities of trees. It is because of this that broad safety guidelines are permitted with the installation of the suitable pumping system. An incorrect pump measurements can harm the borehole and make it unviable. Utilising the proper equipment in your borehole process will guarantee the robustness of your water resource.

A significant element of a borehole yield test is keeping track of the water quality when pumped from the borehole. A water sample is usually taken at the start of the test as well as at the end of the test for a full chemical breakdown, while the electrical conductivity and temperature are typically observed with the water level throughout the test. The water quality is also imperative to see whether it is ideal for household, irrigation or commercial applications. Following South African Standards the highest allowable nitrate content is 10mg/l. An excessive amount nitrate has a significant effect on babies under six months.

How long does yield testing take?

The duration of the test is directly linked to the duty period that the borehole will be pumped at, as soon as the long term pump has been fitted. For example, a borehole delivering domestic water to a residence will have a faster duty period than a sprinkler system borehole. Consequently, the type and process of the test pumping carried out on a household borehole will likely be quicker compared to test for an irrigation borehole.

Other Things to remember.

  • An estimate of the water yield by the driller is not adequate and could be incorrect.
  • If you are fortunate enough to have a borehole that generates a good amount of water, never pump more than you'll need.
  • Groundwater is a highly valuable resource and should not be wasted.

More often than not the continual over pumping of a borehole can result in the eventual total malfunction of the borehole, causing demand to have the borehole re-drilled. This can be a lot.

Every living thing needs water. There's no way we'll be able to survive without water, and while some of the provinces in South Africa has more water than others, there has never been a better time to become more self-sufficient and install a borehole on your property.
But before you do, there are some things you should know about drilling boreholes.

What can I use borehole water for?

Borehole water can be used for irrigation and domestic use. If you've tested your water and decide to make use of a filter, water can also be used to drink and cook with.

Do I have to register my borehole?

If you'll only be using your water source for domestic purposes, there's no need to register it. In case of use for commercial and agricultural purposes, you would have to register your borehole.

How much does a borehole installation cost?

There are many things to consider with regards to the cost of drilling a borehole such as the depth, filtration and pump and the amount of casing used but a rough estimate would be anything from R60 000 to R90 000.

Where will they install my borehole?

It all depends on the size of your property. And in most cases properties in South Africa are enclosed with walls, making it difficult to even get a rig onto the property. A thorough inspection is done by Enviro Boreholes before quotation stage to provide you with all the information.

What's the lifespan of a borehole?

If you do regular maintenance, you can expect to get 20-30 years out of the major components of your borehole.

Is drilling a borehole a good investment?

While there are costs involved in drilling a borehole, once you're up and running you'll have a secure water source and won't have to tap into municipal water ever again. The average borehole can yield up to 20 000 litres of water per day.

If you need additional information from the experts, why not get in contact with one of the team members at Enviro Boreholes. They have more than ten years experience in drilling boreholes and know everything there is to know about the process. Give them a call today.

A complete private water supply installation consists of several elements such as submersible pumps, headworks, management systems and in many cases, water storage tanks.

Water storage tanks are frequently used if the borehole supply doesn't produce sufficient water when needed, or the borehole needs an opportunity to get caught up following a significant period of use. This is in particular ideal for golf courses and holiday resorts that have substantial water demands at set times during the day.

What are the advantages of a Water Storage Tank?

It is advised that the use of water storage tanks where your need for water is most likely higher than the borehole yield and, as well as for drought protection.

Additionally, they turn out to be incredibly useful for commercial usage or farmers that depend greatly on water and have no access to a mains supply which means that if their submersible pump malfunction; they could be without water instantly, having huge implications for the business.

A water storage tank is used to hold water in reserve suggesting that a farmer or company could continue to use their water even if the pump is out of action. This will afford them time to discover the problem and get it fixed.

Along with buying a company time if they come across difficulties, a tank also minimises stress on the borehole by not having it functioning continuously, giving the user more control over their personal water supply.

Warning lights and sensors can also be installed on the storage tanks helping the user make sure that any potential issues are handled before they are out of the water.

Water Storage Tank Essential Factors

The considerations needed when installing water storage tanks will be based on the designated utilisation of the water - whether it is for drinking, agricultural or commercial the requirements can vary.

Do I need to register my borehole?

Based on the National Water Act, you do not have to register ground water usage when it is used for household applications only. Borehole water may also be used for outdoor recreation like replenishing a swimming pool and household disasters like putting out a fire.

What if the driller doesn’t find water?

Your arrangement with the driller will be to drill a hole in the earth, with the potential for tapping into a self-sufficient water resource. If appropriate siting methods were adhered to and in the unlikely event the hole was discovered to be ‘dry’, you will be required to pay the service provider for the drilling. Nevertheless, you won't be liable to pay for any materials and equipment that would be used to complete an installation, namely the pump, piping and electrics.

In conclusion, a borehole is a sound investment. Even though the installation can cost anything from R60 000 to R90 000, having a borehole will add substantial value to your property or home, and eventually, it will represent a smart investment. Assuming that the installation was done by industry experts and with due care.

1. Never service your own borehole

Usually it is advisable to:

  • Ensure the water tank is not too big, so the water in the tank is often refilled with fresh water.
  • Confirm that the container is constructed of approved materials and make sure it is the correct colour for its intended use.
  • Make sure it's fitted with a lid which limits light, is tight fitting and properly fastened, so that birds, pests, and dust can't enter the water.
  • Have the tank annually checked and any debris cleaned out, and the tank sanitised regularly.
  • Guard the tanks against frost

Water storage tanks can be built in segments for construction in confined spaces and are available in various shapes, sizes, materials. Additionally, it is possible to install them underground for those situations where an above-ground water storage tank isn't possible.
If you have any questions about water storage tanks and their installation or applications, get in contact with Enviro Boreholes for more info.

Domestic borehole water usage can be divided into two categories: Schedule 1 water use and General Authorisation water use. Here's what you need to know about both.

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.

Schedule 1 water use

When using borehole water for domestic (household) purposes, there's no need to register your water usage. Domestic usage includes garden irrigation - not for commercial gardens - as well as providing water for animals, given that you aren't supplying a feedlot.

As per the National Water Act, there isn't a maximum set for the amount of water usage when it comes to domestic purposes. However, a water catchment management agency is appointed in each area which might specify a usage limit so be sure to contact the agency in your area to check if there are any limits to water usage.

General Authorisation water use

With regards to general authorisation water usage, it depends on the area which the property is located in, as well as the size of the property. The usage amount is measured in cubic metres per annum. As long as your water usage isn't excessive, doesn't have an adverse effect on the water resource or your neighbour's water usage, and doesn't affect the health and safety of the public, you're good to go.

Under the General Authorisation category, you'll only need to register your water usage if you use more than ten cubic metres per day or if you store up to 10 000 cubic metres of water on your property. This should be done at the Dept. of Water Affairs and Forestry.

If you would like additional information on installing a domestic borehole on your property or getting an existing one to work, get in contact with the professionals. They will also be able to supply you with all the legal requirements before starting to drill. Get in touch with Enviro Boreholes today for a free assessment and quotation.

Installing a borehole is quickly becoming a viable approach to obtain cheaper water for many people with rising utility costs and water bills. Boreholes can generate a fast investment payback, frequently lowering costs by up to 80% of a metered mains supply, all depending on water usage, of course.

Household Water Use

Properties larger than 500m2 with piped water, typically use up to 46% of their water consumption on irrigation. Making use of municipal water for garden irrigation is rather a waste of drinkable water. By using groundwater for irrigation, people could easily reduce their water bills, while lowering the demand on the municipal water supply. Municipalities use tariff rates that rise in proportion to consumption. This has a tremendous effect on the water bill every the month.

Considering the price of fitting and maintaining a borehole, would be the probable saving in water be worthwhile? To answer that question, let's review the expenses involved in installing and maintaining a borehole in a standard residential home.

Below are the main expenditures linked to installing a borehole:

  • Costs to determine if and where to locate a borehole.
  • Borehole construction cost for:
  • Moving of equipment to the site and back
  • Drilling - charged per-hour or per meter
  • Casing entailing supply and installation of durable casing and screen, gravel pack, hygienic seal
  • Development regarding cleanup of the borehole following construction
  • Pumping test expense for post-construction evaluation of borehole and aquifer effectiveness
  • Hydro chemical analysis - water quality tests for a designated use
  • Installation of a pump and drinkable water storage tank and reticulation system
  • Routine maintenance costs for yearly inspections of the pumping equipment, pipework and repair costs in case there are any failures
  • Electricity fees for operating the pump whenever it is turned on

The average cost of a borehole in South Africa is anything from R60 000 to R90 000.

Below are the main expenditures linked to installing a borehole:

Even though there is a capital layout initially, it is obvious that by using borehole water for irrigating gardens can be a cost-efficient and worthwhile replacement for municipal water. A well-maintained borehole can also be a cost-effective, self-sufficient asset. Despite the fact that preliminary expenses of drilling and equipping may be large, you will find long-term financial benefits to groundwater, especially the fact that borehole water is not nearly as expensive municipal water.
