Background
Catchment Area Conservation and Management Plan (CACMP) is integral part of the sector program. Source protection and its sustainability have been identified as a priority area of intervention under the sector program. The sources include perennial spring water, stream water and uncontaminated shallow and deep aquifers that can be tapped for single/ multi village based piped water supply schemes.
Guidelines for source protection under catchment area conservation and management program.
To check the declining trend of the tapped water sources.
To increase the source discharge to a minimum of 18 lpm with seasonal consistency.
To protect the water supply scheme structure threatened due to soil & water erosion and landslides.
To create awareness and capacity building of village community by involving them in planning, implementation, operation and maintenance of catchment area protection works.
Water Conservation and Intensive Recharge Activities under Sector Program:
Rejuvenation of Natural Water Sources
Rain Water Harvesting
Rejuvenation and Conservation of Naula and Chal/Khal
Plantation of Broad leave species
Components:
a) Afforestation
Include plantation of saplings as chosen by the community.
Basic idea is to restore the lost vegetation cover in the Catchment of the depleted water Sources-afforestation is done in a single unit or as different patches of smaller size or other suitable options as per site conditions.
This improves the vegetation cover of the Catchment area and reduces erosion.
Protection of plantation works by coolie walling / barbed wire fencing.
b) Components: Soil and Water Conservation Measures
The structures reduces the runoff speed of water and promote recharging through percolation and also reduces soil erosion.
The following structures are promoted for conserving soil and water conservation in the Catchment.
Stone Check Dam
Crate Wire Check Dam
Cross Barrier and Wing Walls/Bank Protection
Vegetative/Bio Treatment to Structures (Rambans, Agave, Bamboo, Narkul)
Recharge Pits
Percolation Pond
Brush wood check dam
Construction of Chal/Khal
Contour trenches
c) Development of demonstration Grass Patch
