4.2.2 The centrifugal pump will work to introduce the water in the reservoir to the top of the tank, until the liquid level reaches a line, the centrifugal pump automatically stops working, seepage test began, then start the timer timer.

4.2.3 When the liquid level reaches the b line (that is, all the 50L water penetrates into the reservoir through the sample), the timer stops counting.

4. .42 Water seepage is calculated as follows:
