|Irrigation Sector in The National Capital Region
Water requirement for irrigation is closely related to population, demand for food,
production of non-food agricultural and industrial items, improvement in quality
of life and preservation of ecology and environment. Absence of effective guidelines
for conservation of agricultural land and the lack of effective controlling mechanism,
(legal and institutional) in constituent States, both at the Sub-regional and local
levels have resulted in converting the land use from fertile land to urban use regardless
of the NCR Plan.
Regional Plan-2001 did not indicate any specific policies and programmes in this
Studies have revealed that the requirement of water for irrigation in the region
cannot be seen in isolation. The demand for drinking water and industrial use should
also be considered. Other issues are:
Insufficient Water Sources in the Region
Lack of Ground Water Recharging resulting in the Depletion of Ground Water
Policies and Proposals
The direction of growth in the National Capital Region will depend on the availability
of water resources. Demand-supply gap of water is one of the key elements for the
growth of the region, which needs to be bridged through various policy interventions
and demand management. Following policies are proposed:
Regional and Integrated Approach
Integrated Water Resource Management Approach for the region is required for optimum
water resources utilization and demand management including the demand for irrigation,
drinking water and industry. In order to meet the demand of water in the region
for various uses such as irrigation, drinking and industry, the region is dependant
upon various multi-purpose River Valley/Dam Projects where large storages can be
created and long distance transfer of water is done through canals. While the priority
should be given to the drinking water and industrial water demand in the region,
the allocation of water for agricultural purposes should also not be discarded.
Overall demand of the region should be considered by the Ministry of Water Resources,
riparian States and constituent States while signing the MOU for water sharing in
consultation with Ministry of Urban Development and Poverty Alleviation. While preparing
an over all Integrated Water Resource Management Plan in the Sub-regions, the requirement
of water for various purposes, treated sewage effluent and storm water collected
through various rainwater harvesting methods should be considered. This should also
be incorporated by the States in their Master/Development Plans.
Resources Augmentation, Demand Management and Efficiency in the Use of Water
Earlier the water used to be developed rather than being managed. With the scarcity
of available water, alternative could be proper demand management and efficiency
in use of water. It is expected that by the year 2021, there will be additional
requirement of 16,748.0 MCM per annum (assuming that only 50% of water from river
Yamuna will be made available for NCR out of 12,000 MCM per annum), for which additional
water resource has to be created/augmented/existing resource has to be properly
managed. Since augmentation of water resources through large dams on the Yamuna
and Ganga are likely to take time more than perhaps two decades, as envisaged in
the earlier plans, it would be necessary to increase the availability of water by
adopting following means:
Artificial Recharging and Ground Water Harvesting
- Artificial recharge through rainwater harvesting in ponds, Yamuna flood plains,
paleo-channels, ox-bow channels, construction of small check dams at favorable locations
in part of the Ridge for recharge etc.
Demand Management of Water
- Utilizing surplus canal water during monsoon period for recharging the depleted
- Roof-top rainwater harvesting should be made mandatory in building bye-laws especially
in the over exploited and dark Blocks i.e., the areas with unsustainable ground
water resources as identified by CGWB.
- It is expected that the treated waste water from sewerage system in the region
would be around 2,423.25 MCM per annum which must be put for agricultural/non-potable
use to reduce the overall demand for water for irrigation purposes.
- It is expected that water requirement for industrial purposes by the year 2021
in the region would be 4,374.27 MCM per annum, therefore, it is recommended that
water based industries should not be allowed in the region. period for recharging
the depleted aquifers.
- Roof-top rainwater harvesting should - Drip Irrigation method should be promoted
in the region to save water from irrigation sector. Even if 25% of the water is
saved, it would amount to saving of 3,500 MCM per annum.
Decentralization of authority, responsibility and technical units along with community
awareness, participation and monitoring of various aspects is a must for any successful
water resource management system.
