Jal Jeevan Mission (Har Ghar Jal)Assured water supply to every rural household - Long-term sustainability of groundwater sources
Slide2A Road Map for Ground Water Security & Sustainability adopting Scientific Method
(Watershed Approach using Remote Sensing & GIS application)2
Slide33To ensure
ground water security and its long term sustainability
under all circumstances and at all times. REQUIREMENT
To improve ground
water table
To
enhance yield
of ground water based sources
To improve the
water quality
of ground water based sources
AIMS
JJM requirement is to plan project in integrated manner consist of in village water supply system in consideration with source sustainability & grey water management by the community to ensure service delivery on regular & Sustainable basis over the planning period.

SOURCE SUSTAINABILITY
Slide5In the operational guidelines for Jal Jeevan Mission it has stressed upon to ensure drinking water security and sustainability of drinking water sources using an appropriate technologies as well as scientific approach for development of comprehensive water security action plan.

NEED
To overcome the issues and challenges of water security and sustainability of drinking water sources, the suitable
solution can be watershed approach
which can be adopted unit for
the
ground water recharge & conservation
.
SOLUTION
Slide6A watershed is defined as a geo-hydrological unit of an area into common outlet point with the theory of ridge to valley.
