Drilling a borehole for private water supplies Scotland.
We can undertake any work on private water supplies, from the initial installation, water analysis, drilling for water to maintenance on an existing supply in Scotland, Highlands and Islands.
Private water supplies in Scotland are beneficial to commercial and industrial users who use large quantities of water. This can impact massively on costs, as without water rates to pay, the only cost incurred is the cost of the electricity in running the system.
What is a borehole?
A borehole is basically a modern version of a well, but smaller, easier to maintain and less likely to be at risk of outside contaminants.
As an alternative to a mains supply, a borehole provides you with a water source to use as pure drinking water, or for many other purposes (eg irrigation, etc)
Borehole water is normally of high quality, but we provide water testing from a specialist lab, so that if your supply is to be used for drinking we can ensure that the quality of the water by providing and installing the necessary water filtration and treatment.
What are the benefits?
Free Initial Survey - we can help you decide if a borehole supply is right for your property/business without any charge to you.
Environmentally Friendly - boreholes use water taken from an underground source (eg an aquifer), rather than draining above ground supplies such as rivers.
Better Water - borehole water is free from surface pollutants, and Filpumps can supply filters and water treatment (if required) to allow you to enjoy drinking water at it’s purest.
Cost Effective - a borehole can generate a fast return on investment, within an acceptable pay back period.
Money Saving - as borehole water usage is not metered, you will make a saving on water rate charges.
One stop shop - Filpumps can provide you with a complete and high quality service, from initial consultation, sourcing the best position onsite for your borehole (we also offer a water divining service) onsite drilling, water pumps and even filters and water treatment - taking you from the initial idea right up to usage.
Introduction to water supplies
Installing a borehole water supply is a large investment and it is therefore essential that the project is properly managed and the equipment is of good quality and professionally installed. The following notes outline the main steps required to ensure that a reliable and wholesome water supply is achieved.
A site survey is required to establish the optimum position for drilling. This is best derived by using a combination of two skills, the scientific geological survey and the traditional water divining.
Geological Survey- The British Geological Survey will search their records for soil and rock types to establish the most likely position for drilling. This will be backed up by any historical reports from drilling activity in this area.
Water Divining - Finally a water diviner will visit the site and pin point the exact position for drilling based on the geological information and the results of the divining.
A six-wheel drive drilling rig is brought to site and used to drill a borehole 150mm (6 inches) diameter to a minimum depth of 30m (100ft). This will penetrate the overlying soils and enter the bedrock which contains the aquifer (water supply).
During drilling it is possible to get a reasonable estimate of water yield. If this is satisfactory the well is then lined with a 150mm diameter ‘filter screen’, which is a rigid plastic pipe which is heavily perforated at its lower levels. This prevents rock debris caused by the drilling from falling into the well, preventing insertion/removal of the pump and also serves to protect the pump impellor from rock fragments. A rigid steel casing is driven into the upper section of the well to exclude the ingress of potentially contaminated surface water/debris.
Once the well has been completed it is essential to test the performance before proceeding with further capital expenditure. This will establish the two main elements of viable supply
First the well is ‘proved’ by pumping continuously to waste for a set period of time, allowing the aquifer to settle and the silt and grit caused by drilling to be removed.
Once the well has been proved a flow test is carried out to British Standard BS6316 to establish the likely yield which allows the pump to be sized accurately. Finally a water sample is taken and tested.
A schematic diagram of a typical borehole pump installation is shown on this page.
Site Services Installation
The site is finally completed when the pumps are hooked up to the discharge pipework, electrics and controls.
The requirement for water treatment cannot be guessed at and will rely absolutely upon the results of the water analysis. However as a precautionary measure it would be prudent to install some form of microbiological sterilant using UV sterilisation. The main advantage of UV sterilisation is that the water in unaltered in chemical composition or taste and sterilises the microbes as water is pumped through it.
