What is the Difference Between a Wellpoint and a Borehole?

A Wellpoint is possible to be installed where the geological formation are favourable, preferably porous soil and the water table is relatively close to the surface. It consists of a PVC (polyethylene) pipe inserted into the soil with a centrifugal pump mounted on the surface. The installation of a wellpoint takes approximately 2-4 hours.
A Borehole is a much deeper extraction. A Borehole can have the depth of about 30 to 100 meters or even more. A large PVC (polyethylene) casing are used to be able to install a submersible pump to extract the water to the surface. To install a borehole it can take approximately 3-5 days.

BOREHOLE DRILLING PREREQUISITES

Prior to all installations, we provide a written quotation. This will indicate the schedule of work and the associated costs, with our terms and conditions. To provide you with a quotation, we need information. With our knowledge and your information a quote will be ready in no time.

Dowsing: We have installed hundreds of boreholes without using the method of dowsing, but to put your mind at rest, we will put you in touch with a professional geophysicist on your request. He will charge a fee for his service and provide you with a hydro geological survey.

During the last few year’s water restrictions in our province demanded potable water. With the expensive water rates and weather patterns, attention has increasingly focused on the necessity of this vital resource.

With prices now increasing plus standing charges, your wellpoint or borehole water supply can save huge amounts of money. A properly designed borehole can pay for itself, sometimes in a matter of months.

Borehole and wellpoint water supplies offer huge savings to many users, sport fields, housing schemes, farms and leisure centres. The installation of a borehole or wellpoint adds extra value to your property.

 

Constructing a Borehole after the Borehole Drilling process

You have to make sure that the contractor drilling your borehole or wellpoint has experience in your area. How he drills your borehole is just as important as where it is drilled.

In Kenya, Rotary Mud drilling is the most used due to the ground structure. After drilling to the required depth and water is found, the boreholes is lined with PVC casing (made of plastic) or steel casing depending on the ground structure.

Special screens are slotted (screened) to allow the water through at the right pressure. These slots avoid sediment being drawn in along with the water. The thickness of the PVC (class 16 PVC) is determined by the depth of the hole. The thinner classifications is class 12 or class 9. The area around the screened PVC (annulus) is packed with gravel (grade 6) or 16/30 sand that act as a filter. The borehole is now ready to be “developed”. This is done by using a compressor to blow out the chemically treated water. This proses is done until perfectly clear water appears. If the borehole is not “developed” it can have a big influence on the amount of water produced by the borehole. Steel casing is used only if a hard formation is encountered. The method of drilling will change from mud to rotary drilling to air percussion drilling. Steel sleeves are lowered down until the “rock” is struck. The air percussion drilling will proceed until water is struck. Clean and clear water is normally found in these rocks.

If it is necessary to line the hole with PVC, the PVC casing is inserted into the steel casing. The annulus between the steel and PVC is filled with gravel or 16/30 filter sand to act as a filter. The final, but very important part, is lowering a reliable stainless steel submersible pump, powered by electricity into the boreholes. The pump will bring water to the surface under pressure.

The size of the pump is determined by the flow of the water and the depth of the hole. A proper borehole for domestic purposes should deliver between 500 and 3500 litres of water per hour. Great care is taken in the way we do the engineering of the hole. We use safe, non-toxic materials within the boreholes.

 

Maintenance
Why install a perfect and high quality borehole if you don’t maintain it? Prevention is better than cure. To keep your borehole at peak efficiency, and minimize the possibility of a breakdown it is recommended that the borehole and pumps are serviced on a yearly basis.

Maintenance and Rehabilitation:
We offer services to assist with the maintenance and improvement of existing installations.

Rehabilitation of existing boreholes (cleaning with compressor)

Pumps, Parts and Supplies
Each borehole and wellpoint requires its own specific pump and parts for optimal use.

Submersible borehole pumps
Wellpoint pumps
Water Filters
Booster pumps
Fittings, pumps and valves

Water Storage Tanks
A water storage tank is fitted where the water pressure is not enough. Especially if you want to connect the water directly to your irrigation. Holding tanks vary in size and the size chosen will be determined after the amount of water is established from the borehole in conjunction with the quantity that is needed to irrigate. A booster pump pumps water to the irrigation system. The filling of the storage tank from the borehole is attached via a level control device. Booster pumps vary in size depending on the needs and is fitted with a dry run protection unit. It can also be connected to stand up pipes around the property to feed hoses.

With the recent drought in Kenya we have drilled more than 700 boreholes.

BOREHOLE LOCATION
The location of your borehole is mainly determined by the borehole’s purpose and requires desk study, site assessments, and surveys to assess the following considerations:

​​

Output What will it be used for? – Is it for drinking water, household use, irrigation or other water related functions?

Access Is there accessibility for the drilling team and equipment?

Location Is the proximity of the borehole location appropriate for its use?

Yield Will there be sufficient yield and appropriate water quality for the intended purpose?

Quality Have potential sources of water contamination been evaluated in the assessment?

Forms Has the required borehole application form been submitted to the municipality 14 days prior to abstraction?

BOREHOLE DESIGN
Borehole design is important and necessary. A well designed borehole with a professional install should result in a cost effective, reliable, robust method of obtaining water for the future.

 

Further, a well designed borehole can protect the natural groundwater from becoming contaminated. Sadly, borehole design and development is one of the most overlooked aspects within the industry and not enough time, care or attention is put into this vital stage of the process.

 

Current climate models predict that South Africa is to become hotter and drier and the long-term supply and quality of our groundwater should be considered carefully during this stage.

DESIGN OBJECTIVES PRIOR TO BOREHOLE DRILLING

Optimisation Ensure the borehole has the best opportunity to be fit for purpose e.g. highest yield with minimum drawdown

  1. Quality Best quality water possible for the installation
  2. Fresh Free from salt water intrusion near coastal areas
  3. Filtered Sand-free water
  4. Protected Appropriate protection from contamination

​​BOREHOLE CONSTRUCTION AFTER THE BOREHOLE DRILLING PROCESS

Two 1.5 m mud pits are dug

  • The first is to capture the cuttings that surface during the drilling process
  • The second mud pit is to recirculate the now cleaner water back into the hole which assists the boring process

Drilling commences to the desired depth. Once we have water we drop our PVC casings down (unless it is a rock/boulder drill where the process differs). Construct appropriate formation of casings, screens, gravel and chipstone backfill which help filter the water

​POST BOREHOLE DRILLING PROCESSES : BOREHOLE DEVELOPMENT

Once you have a water supply our drillers will:

  1. Thoroughly flush the hole of all loose debris
  2. Insert the pump and let it run for 24 hours to remove any contaminants
  3. Assess the current water yield and improve if necessary
  4. Ensure the formation of the casings, screens and gravel allow for easy passage of the water into the borehole
  5. Ensure the borehole is fit for purpose e.g. yield, diameter, depth, casing and screen, gravel pack/formation etc.

POST BOREHOLE DRILLING AND DEVELOPMENT

  1. The hole is secured with a cap
  2. Electrical cables and the controls for the pump are run and tested
  3. The site is cleaned

TYPES OF BOREHOLES WE CAN DELIVER WITH OUR BOREHOLE DRILLING SEIVICES

There are three main types of borehole drill terrains :

MUD BOREHOLE
Mud Rotary drilling is a versatile and dependable technique ideal for drilling into soft rocks, sand and clay layers.

The process uses rotating hollow drill pipes which carry down drilling muds to lubricate, cool and clean the drill bit whilst drilling the hole.

The Mud Rotary technique also coats the side of the borehole with a thin layer of clay from the drilling fluids which stabilises the wall of the borehole.

 

Once water has been located, the water is flushed clean and the walls of the borehole are stabilised with PVC casings.

In Cape Town, most areas are a combination of mud and rock drilling.

ROCK BOREHOLE

Rock Percussion drilling is used on hard rock layers and uses compressed air to drive a pneumatic hammer into the rock.

​Our rigs are combination rotary-percussion drilling, The combined hammering and rotation of the bit results in the relatively speedy penetration of hard rock.

​Once you have drilled through rock it is a solid hole which nothing can collapse into.

​In KENYA, most areas are a combination of mud and rock drilling.

​BOULDERS BOREHOLE

In areas, like Somerset West, the underlying rock structure consists of large boulders which can collapse into the hole whist drilling.

BESTCARE drilling is a specialised drilling technique in which steel casings are attached to the hammer part of the drill and protect the drill and drilling process from dislodged boulders. The steel casings are left in the ground to maintain the structure of the hole.

​This method, like rock drilling, uses an air compressor which drives a pneumatic hammer through the rock.

 

 

 

 

OUR BOREHOLE DRILLING AND DEVELOPMENT SERVICES

WE DELIVER THE FOLLOWING SERVICES:

PERCUSSION BOREHOLE DRILLING (BOREHOLE)

A variety of borehole drilling methods are used to assess the geophysical property of the underlying area for the drilling of boreholes in private and public sectors. The type of ground and geology of the site will determine depth of the borehole, because ground water flows differently at different locations. The purpose for drilling the borehole will also affect the water quality needed and processes used to sink the borehole successfully.

ODEX/SYMMETRIC BOREHOLE DRILLING

An excellent option when unconsolidated formations are too dense or cobbly for Auger Drilling. Odex is an adaptation of the down-hole air hammer system that is designed to advance casing during drilling. Once a desired depth is reached the eccentric bit can be retrieved leaving the casing in place for sampling or installations.

EXPLORATION BOREHOLE DRILLING

This is the initial phase of drilling for the purpose of determining the physical properties and boundaries of a reservoir. Exploration Drilling should occur before development drilling should take place.

SUBMERSIBLE PUMP AND TANK INSTALLATIONS

The supply, installation and commissioning of a pump system depends largely on the depth of the borehole, piping and the amount of water to be pumped into the pressure requirements of the system. The borehole submersible pump will pump into a pressure tank linked to the main water supply of the borehole submersible pump, then pump out the tank using a pressure pump to the home.

POLE HOLE BOREHOLE DRILLING

Different diameter size drilling and depths required for power line poles.

WATER FILTRATION SYSTEMS

Installing water filtration systems to ensure all undesirable chemicals, biological contaminants, suspended solids and gases are removed from the water in order to produce water for all household purposes.

BOREHOLE DRILLING, MAINTENANCE AND REHABILITATION

Borehole and pump maintenance is important to adhere to in order to ensure the best returns on your investment. Quality constructed private water supply systems require routine maintenance. With regular borehole maintenance check-ups you can not only extend the working life of the borehole but also maintain its efficiency and borehole yield.
