The water supply scenario of Machchhegaun is a typical urban water supply situation of Nepal. Based on field visit, consultation with various stakeholders here are some of the suggestions for all the stakeholders working in Machhegaun:
Water Security Plan
The major problem faced in Machchhegaun is because of its sole dependency in ground water. Hence water security plan helps to identify other potential spring resources in the area and managing the existing resources.
Alternative Water Sources
Since there is an increased roof/terrace area in urban areas, suitable rainwater harvesting structures can be adopted so that every drop of rain can be stored and utilized. Apart from that, the unwarranted water received during rainy season causing water logging and inconvenience, can be utilized for groundwater recharge by diverting it into suitably designed structures. Moreover, residents of the locality must be introduced to cost-effective techniques to install rainwater harvesting structures at their homes.
Retention, Recharge and Reuse (3R)
As per the water security plan various technique can be adapted to protect the existing water resources. One of the most necessary principle for this is 3R principle which is applied for retaining water through small holes, ponds and afforestation; recharging the ground water through these holes and ponds and finally reusing these water especially during dry season. Since the southern side of Machhegaun is well covered with hillocks and forests, 3R principle will be effective for reviving its dried water resources.
A part from water security plan, hydrological study of the aquifers of the area is most crucial. Since these sort of study has never been done before in the area it will come up with clear picture of ground water status of the area. Based on which, future of existing boring holes can be determined and can provide scientific base for water security plan as well.
