Boy destroyer of the Faucet in the water tank

We have Water tank in the learning center. It is very y important for us to have water tank. Through the water tank we can stock water. It takes for how many years before the faucet of the  tank was destroy. We used the rain if the food classes having their actual cooking. If  in case the Kalahi is not functioning. But sad to say last month the "faucet "of the water tank was destroy. And the small "fuacet"also was stolen by some one else. I heard many stories about that case. I asked already the small children playing one time during rainy season. When I'm having my class a saw a boy playing the water in the tank. Not only in the foods class but all of are benefited of the water tank.

I  called the attention of the small boy. I talked to him softly about the faucet. I asked some questions with regards to the problem in the faucet. The young boy answer my question. One of his friend  try to open the cover of the tank. But the boy cannot open he climb and the boy put his to legs in the plastic faucet. At that time the plastic faucet was cut. I asked also about the small faucet. The young boy told me that they play the faucet and then they throw away. I told the boy to find the faucet and  I promise him to give reward. After one week I asked the young boy if he find already the faucet. He said that he forgot the place where they throw  away the faucet. I told the boy if he can give me another information about the faucet. I will give a gift.
