Water supply boreholes
One of SafeLane Global’s most commonly delivered engineering services is the installation of water boreholes for commercial and domestic use.
It drills for public water supply companies, water bottlers and brewers. It serves farmers for crop irrigation and general water supplies, as well as hospitals, schools and domestic private water supplies.
One of SafeLane Global’s most popular engineering services is the installation of water boreholes to provide private water supplies for commercial and domestic use.
What is a water borehole?
Water boreholes (also known as water wells) are deep, narrow wells that tap into naturally occurring underground water. To use this water, a high efficiency pump is installed to extract the water from the permeable rock below. As the water passes through the ground, it flows through layers of rock and chalk which act as natural filters. This produces a private water supply that is often purer than that provided by the water companies.
How much water can a borehole produce?
The average UK person uses 150 litres of water a day. A single water well can produce up to 20,000 litres (4,400 gallons) of pure water every day without any permissions or licenses.
That’s a huge amount of water and it’s free – want to know more? Get in touch with SafeLane today
What are the benefits of installing a ground water well?
The benefits of your own, personal water supply include: independence from your local water company, hosepipe bans become a thing of the past, no water meters or increasing water bills, pure water that’s free from chlorine and fluoride, the same water pressure as the mains supply, help conserve the nation’s mains water reserves, unobtrusive, reliable, easy to maintain add value to domestic or commercial property…
Domestic water wells explained
There are many advantages to having a domestic water supply on your property, including slashing water bills, providing purer water, and adding real value to your home.
Drought or no drought, a water system will provide your home with an endless supply of water that you can rely on, whether you want the water for your garden, to fill a swimming pool, or for drinking.
It’s your own private water supply.
You don’t need any licenses to extract this much. It’s your right. And yes, it is free water.
As specialist drilling contractors, SafeLane Global provides you with an all-in-one domestic water borehole installation service for the home; from surveying to drilling, pump design to pipework.
As the wells are a direct alternative to a metered mains water supply, it won’t take you too long to recoup the well’s installation cost either!
Commercial water wells
For UK property developers and commercial business owners looking to take greater control of utility bills, water wells present an attractive and viable proposition.
Enabling savings of up to 80% on annual water bills compared to the mains water alternative, a commercial water borehole is a solid investment for any business consuming large quantities of water on a regular basis.
SafeLane has helped hotels, swimming pools and leisure centres, farms, garden centres, golf courses, and major manufacturing plants benefit from a private water supply. One that’s pure, constant, and free.
All you need is an abstraction license, which SafeLane can arrange for you.
SafeLane Global provides you with a complete installation service; its engineers survey, drill, test and install – everything you need for a safe and reliable private water supply for your business.
The drilling process
Pre drilling survey
Before any drilling takes place, a thorough survey is carried out first by hydro-geological consultants arranged by SafeLane.
This survey confirms:
- the composition of the ground
- if the ground is able to be drilled through
- if water is present
- the waters depth, quantity, and quality
Drilling and lining
Following a successful survey, a specialist water well drilling rig is brought to your site, along with all other needed equipment. SafeLane has systems in place to keep everything tidy.
The following drilling and lining process then follows:
- local check for underground utilities e.g. gas, electricity, telecom
- drill an 8in (avg.) borehole down to the water table (can be as deep as 200m)
- depending on geology, install temporary steel casing to prevent collapses during drilling
- insert a minimum 5in plastic or steel casing and a slotted screen to the bottom of the hole
- back fill the gap between the slotted screen and borehole walls with recycled glass gravel
- cement or grout the gap between the pump chamber and walls at the top of the borehole
Pump and water quality testing follows.
Pump and water quality testing
Testing determines your exact pumping requirements and the quality of the water.
Using a submersible test pump, the flow of water coming is checked, in terms of the natural water level, quantity and re-charge rate of the borehole. This enables the correct sizing of your pump for optimum efficiency.
It is very important that the water is also tested. While the water is generally safe to drink, it can sometimes include dissolved minerals or impurities.
For water testing, samples are sent to a UKAS accredited laboratory to establish the exact content of your water.
From the test results, any water treatment systems can be specified to enable you to comply with UK water drinking regulations and ensure you have a pure, potable water supply.
Water pump system: design and installation
The pump is critical to your water well’s performance, it’s what brings the water to the surface. It needs to be efficient, economical to run, and reliable.
As a specialist installer of domestic and commercial water boreholes, SafeLane sizes, designs and fits pumps to suit all manner of water system applications.
For the borehole itself, installation of the DAB, Grundfos or Lowara brands of water pumps is usually preferred. High quality and competitively priced, they range from standard 4in and 6in submersible stainless-steel pumps, to high powered circulation pumps and pressure sets.
If you’d like to add a water storage system as well; SafeLane also designs and installs all kinds of bespoke storage and pumping systems.
These include pumps to support water tanks from 1,000 to 20,000 litres in size, simple pump booster systems for domestic water supplies, or multiple pump boosters supplying water at high pressure to commercial premises.
A submersible well pump is installed into your water well within the pump chamber.
An unobtrusive underground well chamber or well house is then installed above the borehole to protect the well head, pump controls and borehole water treatment equipment – this is a requirement of the private water supply regulations.
Your SafeLane engineers will also dig the trench and install the pipework to pump your water to its point of use. And if you need them to, they’ll also install your water storage tanks exactly where they’re needed – above or below ground, whatever you prefer.
Any waste material will be taken away, the site will be cleaned up and you will be left to enjoy your own private water supply.
While water extracted from a ground water well is perfectly safe for us to drink most of the time, to comply with the UK’s national drinking water regulations, a water treatment system is required.
Having analysed your water quality, SafeLane Global installs a treatment system to deal with any irregularities in water content to ensure you receive an endless supply of safe, pure, potable (drinkable) water.
Integrated water treatment systems typically include UV (ultra violet) sterilisers, iron and manganese filtration units, RO (reverse osmosis) filters and more besides. It’s the complete solution.
Installation costs and considerations
Water borehole installation costs depend on the geology of the ground being drilled, the general site conditions, location, ease of access for drilling rigs and so on.
As a specialist in water well drilling, SafeLane provides you with quotes that provide a clear breakdown of all costs to make it easy to understand.
Here are some typical cost considerations, but please contact the SafeLane team for a project specific estimate:
Before providing you with a quote for the cost of drilling a borehole, SafeLane first needs to organise the hydro-geological survey for you. Costs are dependent on the site and quantity of water required.
The cost of a ground water well is based on a per meterage charge for drilling. These costs are dependent upon:
- diameter to be drilled
- depth to be drilled to
- ground conditions
Please contact us for a site specific quote.
Lining and packing the water well
The charge per metre for the supply and installation of well screen, casing and glass/gravel filter pack is dependent on the diameter and specification of the final installation. Materials can include PVC and stainless steel.
As a requirement of the private water supply regulations, a purpose built manhole chamber is installed over the head of the borehole. This protects it and allows for access. For a commercial water system the cost of a well head is typically £1250.
The pump system is a critical component. The cost of the submersible pump system and electrical controls depends on the well depth, flow and pressure requirements and how far water has to travel to reach the property.
The cost of moving drilling rigs, equipment, materials and personnel to and from the site depends on location and access.
A full chemical analysis of the available water is required. The test costs vary depending on requirements and a full chemical (Suite B) water analysis certificate is provided for your reference.
Is borehole water safe to drink in the UK?
As borehole water can sometimes contain dissolved minerals or contamination, SafeLane has water tested by an accredited laboratory that gives a detailed report of the water. Where necessary, the most appropriate and effective water treatment system will be recommended and installed by SafeLane.
Following water analysis, SafeLane will quote you for the cost of water treatment systems that you may need to meet current UK drinking water regulations.
