Ground Tanks In Urban Or Rural Settings; The Answer To Water Crisis

Eluderio S.Salvo
Development of Environmental System, Inc., Philippines

Abstract

The Philippines is a tropical country situated approximately between latitudes 5° and 20°, north of the equator and longitudes 117° and 126°. This island is annually visited by an average of 30 typhoons dumping an average of 2500 mm of r ins. This large amount of rainfall, however, is not evenly distributed throughout the year thus causing long periods of wet and dry months

Analyses of the annual distribution of rainfall shows that during the period from January to June, the rainfall is about 31% of the annual average while from July to December tuber, the rainfall is about 69% of the annual average.

It is to the problem of water crisis brought about by the long dry, spell that. the use of around tanks is addressed. It can be concluded that rain water recovery through the use of ground tanks is an economical method which can be utilized in urban as well as rural water supply systems. Furthermore, ground tanks will also help in minimizing the flooding problem accompanying intense rainfall.
