As well as any hydraulic engineering construction, household well needs periodic cleaning and sanitation. For carrying out similar works the place of water intake needs to be prepared previously, having extorted from it water. The way of pumping out of water is defined by the sizes of well and technical means which are available at your disposal.
It is required to you
- - ladder;
- - capacity;
- - submersible pump;
- - safety rope.
Instruction
1. Before pumping of water clean well from possible superficial pollution (branches, sticks, foliage). It is the for this purpose most convenient to use ladder of the suitable sizes and also the help of the workmate.
2. Lower ladder to the mine of well and reliably establish on soil. Raising of objects on surface can be carried out by means of well collar and rope with the capacity attached to its lower end. As capacity use bucket, tank or basket. Bringing cargo to earth surface, observe safety precautions.
3. If the bottom of well is covered with essential layer of silt, use the specialized ilososny machine for its pumping. It is possible to order it in the organization which is carrying out clearing and drainage works. One such machine is enough that for once to extort from well up to 10 m3 of silt and other pollution.
4. After release from dirt of internal part of well install in it the pump. For wells with height of water more than 1 m use the submersible pump, at smaller level also surface will be suitable.
5. Mounting pumping equipment in the mine, surely fix it by the safety rope performing function of support of the pump. The rope can be made of nylon or stainless steel not less than 3 mm thick. The lower part of the pump during its work should not concern bottom.
6. Turn on the pump and make pumping of water from well. Time of liberation of well is defined by hydrotechnical characteristics of water intake (the well sizes, speed of migration of water and so on) and also the power of the used pump.
7. Upon termination of pumping of water carry out additional cleaning of bottom and walls of well. If necessary renew "pillow" from river pebble or crushed stone. For the purpose of disinfection process walls chloric solution by means of large brush or the spray. Similar prevention is recommended to be carried out at least once a year.
