A prognosis—established by a hydrogeological and salty water detection can normally be arranged within 2 days. With this, Water Detectors B.D Ltd produces an estimate, and this takes a day.
On-site work can span 3 days: drilling is 3 hours and pipe construction works takes 2 hours on the first day, on the second day we allow the sediment and debris to settle because this can result in premature pump failure. On the third day, cables need to be installed, the submersible pump placed in the borehole and tested, pumping to clear the supply.
Water is then sent to the laboratory to verify purity. This is likely to take three weeks but water can be put to use us await the results. So, the short answer is normally a month for supplies.
The good news is that, as Water Detectors B.D. Ltd has a complete service in-house, it will be handle within two weeks. The entire project will then be hand-to the client and after sale-service will start after the third month.
Water Detectors is the only water drilling company in Ghana so far that has an ultra modern machine to check for presence of underground salt water before drilling your borehole, Water Detectors also check for quantum of water, best place to drill for enough yield,the depth of the water, the rock percentage and other interesting and helping details before drilling the borehole.
Small quantities of salt are deposited onto the landscape every time it rains. Evaporation and plant transpiration remove water from the landscape but leave the salt behind. This concentrates salt over time. Evaporation can also directly increase groundwater salinity in areas where groundwater is close to the surface. Old groundwater can also become saltier as it passes through aquifers and picks up salts from dissolved minerals.
Although the presence of salt in the Africa landscape is natural, the salinity in groundwater and movement of salt into groundwater-dependent ecosystems can be increased by human activities. Increases in groundwater salinity can be caused by:
Groundwater salinity can be also reduced at times, such as when rapid recharge from flooding flushes out or dilutes salty groundwater. Broadscale changes in groundwater salinity occur very slowly, over decades or longer. Therefore, groundwater salinity is usually monitored infrequently except where human impacts are of concern. With Water Detectors pre-salt detecting River G machine, we can give you accurate report about your land before drilling. Example if the underground water is SALTY,FRESH OR VERY SALTY and many more before drilling the borehole.
If you cannot connect to mains water, the answer to this question is obviously yes!
However, even those people with access to the mains sometimes prefer to use water that has not been processed for public supply. Water from a borehole is not treated with chemicals; so there is no added fluoride or chlorine. In fact, most of the bottled water available from the shops comes from boreholes…many of which have been drilled by Water Detectors B.D. Ltd
Water Detectors B.D. Ltd only installs high-specification equipment. Manufacturers state that the pump has a 10-year design life, and they are very reliable.
A number of operational factors have an influence, for example low mains voltage, or aggressive water which is exceptionally acid or alkaline. But replacing a pump is normally a straightforward process — small domestic type pumps are suspended on a nylon rope to enable it to be brought to the surface. The Water Detectors team reckons that a changeover time will usually take them around 3 hours on-site.
It is strongly recommended that you take out a Water Detectors B.D. Ltd maintenance contract — this includes annual testing of your pump’s performance. You also benefit from a priority service, discount on parts and labour, and lower callout charges in the event of an emergency. For a small additional fee you can also have a regular water analysis survey.
The average range is 100 meters, although the Water Detectors team do sometimes drill to 150 meters or more if required.
A new borehole, installed to a high standard, and with modern materials such as PVC and stainless steel should last a lifetime. Difficulties can arise particularly with old boreholes where the use of low quality material, example, pumps,electrical cables, bad construction with p.v.c. Pipes after drilling and more to that inexperienced try and error borehole contractors.
Careful design and construction eliminates many problems at source. For example, the hallmark of a good borehole is that the velocity of water entering through the screen travels as slowly as possible.
The problem being addressed is that water that is moving rapidly is likely to drag in sediment and debris, which can cause the migration of silts and sand and again this can result in premature pump failure.
Also, fast-moving water can abrade the screen. Some contractors create their own screens by drilling holes or angle-grinding slots in the screen material. It saves on cost, but this is false economy, and is likely to create future problems. For this reason the Water Detectors team use proprietary screens that are factory prepared and which are scientifically designed to minimise entrance velocities whilst giving the maximum open area. Before installation, we use our borehole inspection camera to check for sediment and other problems that may cause borehole failure in the near future and solve them quickly.
Where sediment builds up, the company is normally able to clear it by using its air lift system. With a Water Detectors borehole, you can be sure you have the best design and materials and that construction methods will engineer-out problems.
