This Summer Waterseekers under took a new borehole for Brooklands Nurseries on the Newstead Abbey Estate. The Estate consists of over 80 properties and the majority of these are privately owned. Because the Nurseries were at the end of the line as regards the water supply, the nursery was struggling with volume and pressure, which was having a major impact not only on their day to day routine but it also put a stop to any potential growth plans the client had.
The borehole was constructed in close proximity to the existing water tank, the borehole was drilled to 60m into the sandstone formation and the supply was plentiful, allowing the client to deliver water around the nursery without worrying about it running out.
The clients only comments were that had wish he had done it 10 years ago as it would have saved him a lot off stress and worry over the years.

Waterseekers was called to look at an existing borehole a Nursery that was causing problems due to the high level of iron in the water. The existing borehole was drilled in 1999 and from day one Iron removal system/filters were in place. The levels of iron made it very difficult to filter out and over time the maintenance on the system became a daily process that was taking up too much of their daily routine.
We inspected the borehole with a down-the-hole camera to establish the construction of the borehole. It became apparent very quickly that the construction was the cause off the issue but unfortunately we couldn't do much with the existing borehole.
It was agreed to construct a new borehole at the opposite end of the site, where construction commenced. The goal was to seal off the top 33m of shale into the competent millstone grit. The previous borehole had 4m of steel in the borehole and was not cemented in place. 33m of 219 millimetres 8 millimetres wall steel was installed and the annulus between the steel and the strata was cemented in place. We then open holed the borehole to a depth of 96m, maintaining a good conductivity in the water, coal was encountered at 93 meters and the conductivity of the water increased indicating higher levels of possible elements/metals in the water. At this point we ceased drilling and installed a tremmie pipe and cemented the borehole from 96m to 90m to stop contamination from the coal band.
The borehole proved very successful with no iron present. In fact, no metals at all! The water was deemed drinkable by the laboratory that carried out the testing and the client is very pleased with the outcome. Waterseekers decommissioned the old system including decommissioning off the old borehole.
Finally and on completion of the new borehole Waterseekers installed pre-insulated suitable storage tank, and a GRP plant-room with a variable drive booster set, sized to maintain the correct volume and pressures around the nursery.
Early this year Waterseekers was contacted by a very well know Distillery in Northamptonshire. They wanted to look at abstracting water to use in the distilling process. The client had already had a prognosis report commissioned by the British Geological Survey and the outlook was not very good, with a 90% chance of hitting a dry hole.
We decided to attend site to see if we could locate a suitable supply by water divining. According to the farmer many years ago a drilling company drilled several holes across the site to see if they could locate water with no success. Our MD Lee Hormell spent a day on the site divining and located a potential source that the client was keen to explore.
We mobilised on site in October of this year and commenced drilling and found water to the delight of the distillery and to the amazement of the farmer. The borehole is producing 1500 litres of water an hour which is actually double the amount required.
Waterseekers is now working with the Distillery to provide further storage and equipment.
Bhakitevedanta Manor required a solution for water and water storage for multi-purpose use at their centre in Watford. WSWDS installed a borehole into chalk to a depth of 80m. We installed 3 no. 20,000 litre potable water tanks and plantroom consisting of controls, booster pump and a complex manifold system.
As a result of experiencing a high mineral content in their water supply a CCTV inspection of the borehole at Kings Croft Hotel in Pontefract was required to determine the borehole construction and condition to enable rehabilitation of the borehole to restore it back to its optimum condition.
