Accelerated Completion of Major & Medium and Lift Projects

•If all the proposed major & medium and Lift irrigation projects are accelerated to be completed by 2030, then extra benefit to farming households at MSP of rice for 2016-17 @Rs 1500/quintal and farmers input cost of about Rs 13000/Ha will be:• Extra food grain production due to early completion of projects between 2021-2051 will be 5061 kT i.e. about 5 lakh truck load of 10 tonnes each or average 16700 truck load per year for 30 years (2021-2051).•Extra income to farming household between 2021-2030 = Rs 35000 per farming household (assuming farming population as 60 % and a farming household consisting of 5 persons). This amounts to extra rise of about Rs 3900 per year on an average basis.•Extra income to farming household between 2021-2051= Rs 1,00,000 per farming household. This amounts to extra rise of about Rs 3300 per year on an average basis.

Use of Treated sewage for Industries

•Projected population of the sub-basin in the year 2051 = 4.74 M.

•The sewage generation from domestic sector is about 80% of the total supplies (Urban 220 lpcd, rural 150 lpcd as per NCIWRD-1999 report) i.e. 80% of 315 MCM = 252 MCM.

•The total projected water demand for industrial sector in 2051 in the sub-basin is about 285 MCM.

•Thus, a large proportion of the industrial water demand can be met by treating the sewage and supplying the treated water to them, wherever feasible, especially in Champua and Anandpur sub-catchments which are likely to face water stress in 2021 and 2051 scenarios respectively.

Recommendations of the Study• Irrigation water use efficiency improvement measures • Zero discharge and recycling of treated sewage waters to the

extent feasible in industries.• Expeditious completion of proposed projects.• Enhancing irrigation coverage, use of high yielding variety

seeds, manures & fertilisers, pesticides, and access to extension services.

• Crop diversification - cash crops , oil seeds and pulses.• GW use is about 31%. Conjunctive Use of SW and GW

resources.• Hydropower potential of about 535 installed capacity needs to

be harnessed.• Soil and Water Conservation practices, wherever feasible.• Scientific determination of e-flows.
