Innovative Model for Developing IWRM Plan
Treat water as part of a
connected system
Use a balanced approach
to manage needs
Use scenario planning to
identify risks and develop
mitigating strategies

• Recycle Water
• Recycled Water From External Sources such as Delhi
• Recycle Water From Within Development
Implementation Framework for Sustainable Irrigation Practices
Development of framework for increasing
efficiency in irrigation sector by reducing
water losses
Use of sprinkler, surface and subsurface
drip, bubbler and micro-sprinkler irrigation
technology to reduce the consumption of
water for irrigation.
Develop an optimization model for rotation
of crops to maximize the profit to the
farmers by using crops with high water
use efficiency.
Use of alternative technologies for
growing non seasonal crops and
vegetables
Use of wind mill and solar energy driven
low pumping to design micro-irrigation
system with limited water supply to
prevent the over-exploitation of
groundwater.
Strategies for growing crops based on
availability of water
Assessment of Potential Surface Water Resources Augmentation – Technical & Commercial Feasibility Keeping Environmental Sustainability in Perspective
Development of sustainable local rain
water harvesting techniques
Reassessment of Technical, Commercial
and Environmental Feasibility for
harvesting excess water from perennial
rivers such as Chambal.
Identification of feasible measures for
improvement of existing irrigation canal
networks in the region, for minimizing the
water conveyance losses and optimized
use of available water.
Feasibility of revitalizing the Sahibi River
catchment area for utilization of monsoon
flow.
Reuse/Recycle Water Potential
Ability to use recycle and reuse water in KBNIR will be a key strategy in
ensuring sustainable water supply as this is independent of climate change and
less energy intensive compared to brackish desalination
Project will carry out following structured assessment using our experiences
from past projects in Singapore and in India.
Sustainable brine disposal solution
Aquifer Storage and Recovery
Storage of water through wells during times of excess for future recovery to meet peak, emergency, or long-term demands
Capture temporal sources for increased reliability/improved water quality
Eliminate evaporative losses in reservoirs
Avoid loss of riverine habitat associated with surface reservoirs
Increase water treatment works/conveyance system operational efficiency

Decision Support model for Optimization and Monitoring
Develop System Monitoring Framework, Instrumentation Plan and Telemetry -
Some examples of sensors that would be considered include:
– Source Water Automatic Meters: provides quantity of raw water and treated water
produced
– Groundwater depth sensors: provides information on groundwater withdrawal
– Water quality sensors: provide information on key water quality parameters to optimize
treatment and water acceptability to customers.
– Distribution System - Automatic meters for customers: provides information on water
pumped into the distribution system and individual customer usage.
– Pressure sensors: provides information on system pressure profiles which can be
related reductions related to pipeline breaks and leakage related to excessive system
pressure.
– Water quality sensors: provides information on water quality degradation throughout the
distribution system and is used to optimize system operations and improve customer
satisfaction.
– System-wide Pump Energy sensors: the data from these sensors will be coupled with
meter data to develop a cost/mgd of treated water produced, treated water delivered,
and wastewater treated.
