5. Conclusions and recommendations
5.2 Suggestions for future studies
In addition to the above mentioned conclusions, this study has also opened a wide range of research prospects for the future. This study has given the emphasis on collection of rainwater from the point sources which help in accurate measurement of rainwater harvesting potential as well as the designing of the rainwater harvesting structure. This could ultimately save the cost of infrastructure that will be recommended. Therefore, it is suggested to precisely measure the number of people staying in a unit, roof area and the amount of rainfall as closer as possible. In addition, this study did the preliminary investigation of stable isotopes of rainwater of different locations as well as in different seasons; the research could highlight the existence of a complex mixture of nitrate sources. The results of this method have further opened in the identification of nitrate sources in the valley. The rainwater showed natural in itself, however, due to limited time and fund, microbial and heavy metal analysis could not be conducted which is essential in recommending for drinking water, so this study further suggests to make detailed study on parameters alike microbiological and heavy metals.
