Drilling Boreholes

Aquasource (SW) Ltd t/a Ground Source South West has started a Ground Source Heat Pump project on the Lizard Peninsular.

The project involves drilling up to 120m deep boreholes in the very small front gardens of social properties on an estate.

The access is very tight and we were just able to squeeze our Beretta T46 into the space available.

Tidyness and site cleanliness is paramount with all dirty water being tankered off site and the ground covered in tarpaulins and plywood to protect it from the drilling operations.

The ground is a very hard granite type rock with clay bands.

If you have a site that needs drilling for Groundsource Heat Pumps, or a water borehole, please give us a ring on 01726 824837



South West Water customers have highest bills according to new figures

Water Pressure:-Low Pressure on Mains Solved

The Problem:- Low Water Pressure

A client in Cornwall contacted us complaining that the water pressure supplied by the local water supplier was not high enough to meet their demand.

Our clients had recently refurbished their property to a high standard. Their plumbing contractor, Pip Kevern Plumbing and Heating, needed a bigger supply to effectively run the new showers and baths.

The local utility could not supply the water pressure required due to the very long pipe length and small size of the mains supply.

Because we have worked with Pip many times in the past to solve water supply problems for his customers. Aquasource was asked to come up with a solution.

Consequently Pip Keverne and Aquasource worked together to solve the clients problem.

The Solution

We suggested that a booster set attached to a storage tank would be a much cheaper and equally effective alternative  to a new, bigger, and very expensive incoming main supply from the utility provider. .

We installed an electronically controlled booster set to a pressurised system. Also  a debris filter to filter out any dust.

To sterilise the water we fitted a u.v disinfection system.

This system supplies the house with all the water it could need.

The system was designed to fit in a small out house. This was due to space constraints in the property.

The system was installed and commissioned in one day. Consequently our customer can now shower in comfort without having to worry about a lack of mains water pressure.

The job is in Cadgwith, On the lizard, in Cornwall.

Ground Source Heat Pump Boreholes in Newquay

Aquasource (SW) Ltd t/a Groundsource South West have completed 10 boreholes for Ground Source Heat Pumps at a new housing site in Newquay. The  use of Ground Source Heat Pumps will enable the  properties  to be Zero Carbon Homes.

Geothermal hole details.

Due to expected ground conditions drilling technique used for the Ground Source Holes was down the hole percussion. This technique  enables holes to be drilled through hard solid rock.

The Ground Source holes were drilled to a depth of 85m, probe inserted and grouted with Geothermal Grout from the bottom up.

The Geothermal grout seals the holes, provides good heat transfer from the ground to the probes and  prevents contamination of the ground water by dirty surface water. Bottom up grouting ensures that the holes are filled completely with no gaps that may prevent efficient thermal transfer. This can be due to partial hole filling and is to be avoided if possible.


Ground Conditions

The holes were completed despite some very challenging ground conditions which tested the ingenuity of our drillers to the limit!

This was because a near horizontal layer of soft clay needed to be overcome to enable the successful insertion of the Ground Source Geothermal Probes.

Consequently all the holes  were cased through  the clay zone into the stronger rock below.

The amount of water encountered during the drilling also posed problems for the drillers.

The wetness of the holes however is good news for the performance of the Ground Source Heat Pump system.
