EXAMINATION OF FAILURES OF CONSTRUCTED WATER WELLS

The example of judicial construction and technical examination of the constructed water intake well in one of settlements is considered in this article. The analysis of failures occurred during the operation of the newly built water intake well was carried out. The point moments on the quality and timing of the work performed there are often disputable when putting objects into operation. If these questions cannot be resolved by mutual agreement of the parties, their decision is transferred to the courts, which appoint judicial construction and technical expertise. The type of judicial engineering and technical expertise, judicial construction and technical expertise plays an important and sometimes decisive role in legal proceedings, including the consideration of civil disputes in courts of General jurisdiction and arbitration courts. Judicial construction and technical expertise was appointed on the basis of the decision of the arbitration court for a new water intake well built in one of the settlements of the Kursk region. The reason for the appointment of the examination is that this well has ceased to provide the planned flow rate, and the produced water meet the quality requirements. Two main reasons led to the decline in the technological characteristics of the well and the deterioration of the quality of the produced water: the wrong choice of the pumping unit and the lack of a water tower on the network. The selected ECV 6-16-140 pump created excess pressure in the network, which was then reduced by the installed automation (frequency Converter), and accordingly the well flow rate decreased. The use of frequency converters is not always useful, but can even have a harmful effect on the operation of the water supply system. In addition to reducing the flow rate, the operation of the frequency Converter caused the combustion of several pumps operating in unacceptable modes. The work of the frequency Converter installed on the pump unit with overestimated characteristics led to the turbidity of the produced water, there was an uneven consumption of water from the well.
