CHOOSING THE RIGHT BRICK

If you want to buy bricks, check the finish of the brick. It should be rectangular with sharp edges and bright red. See that the bricks don't even have the tiniest of cracks.

Take a brick and drop it from a height of about three to four feet. The point where it crumbles completely gives you an idea of the relative strength. If one variety of brick breaks at three feet and the other at four feet, the latter is almost twice as strong as the former.
Weigh a brick, then immerse it in a pail of water for about 24 hours and weigh it again. If the weight gain is very high, then the brick is of inferior quality.

A few things to remember while hiring your borewell drilling contractor:

1.Make sure that the contractor has all the required infrastructure (like drilling rigs) for the job and can source qualified geologists to conduct a survey of the land to locate water.

2.The drilling company should also have the technology for installing pumpsets and servicing these sets later on.

3.During the construction of the borewell, the most important thing is the installation of the casting pipe. If this is not done properly you are liable to get silty water. If you use inferior casting pipes they will quickly corrode and the life of the borewell will be lessened.

4.The size of the drilling pit is very important. According to government rules, the pit's diameter should be 147 mm. If the diameter is less than this, the submersible pumps won't fit in. If you are not careful, the contractor can just dig the pit and walk away, which would be of no use.

5.The actual quantity of the water yield can be measured with the help of a V-Notch. Make sure the contractor shows you the yield by passing the water through the V-Notch. When you have installed your pumpset, see that the contractor guarantees after sales service.
