construction of ferrow cement tanks in schools

We now have enough water says the headteacher, my children have been taking time to go to the village, to draw water which is dirty. Most of our parents have been complaining that the performance of our children hes gone down.
 But after wewasafo constructing for us a tank we have enugh water in school.So long long it rains this tanks stores alot of water that can serve us through out the year. Our children have concentrated on academics especially std 8 students. I hope the school performance this year will improve compared to previous one
