Published by Author in category Health and Fitness | Leave a Comment

Drilled wells are done in those areas where there is a need for water supply, and there is no centralized water supply system. This can be cottage villages, located far outside the cities, garden partnership or country houses. Also, in cases where the system of centralized water supply it does not make economic sense.
Drilling has many specialized construction and drilling companies that have at their disposal all the necessary drilling equipment.
Drilling is carried out with the mandatory compliance with all building codes and drilling technology: in this case, the supply of water to the site will be uninterrupted, with the necessary debit (amount) and water quality and water treatment system will serve for a long time.
If a water well drilling carried out on new unknown areas, you must first conduct exploratory drilling to determine the amount of work and depth of the location of groundwater at the site. Previously there were already similar work, then you can immediately start drilling development wells, using the available a priori information and documentation.
Wells, depending on their destination can be: operating, exploration (drilling to verify the presence of water) or operational (well after drilling shall be in operation). Operational exploratory drill hole with the calculation of future installation of a pumping equipment required diameter, power and performance. If the well meets the required parameters, then it is transferred to a permanent mode of operation.
Well on the sand or sand-hole – a hole depth of 10-40 meters, drilling which affected the upper layers of the earth (sand horizons). The biggest advantage of sand wells, according to most users, is their low cost. Depth of wells in the sand – not great, respectively, in the beginning you can save a lifetime … so well for 5-7 years. You should be ready for the next few years you have to pay again – for a new well …
Well on limestone or artesian well – a hole deeper than 30 meters in limestone aquifers. Well on limestone, as a rule, deeper sand holes. That is an artesian well would cost more than the sand (because the price is well formed, primarily from its depth). But the life of an artesian well 50 years and over …
So first you decide what type of wells – in the sand or on limestone – would like to have.
Then you decide what will be “receptacles” of your wells. This tube (casings), in which water will rise from the well to you on site.
You can choose the economy version – steel (metal) pipe. It receives about 20% of users of wells.
You can also opt for “dual” system – as a casing in your well will be used two tubes: metal, and in it – plastic. Such a construction hole significantly increases its service life.
