Dam & Appurtenant Works - Mullaperiyar Project
Government of Kerala has decided to construct a new dam in the place of the century old Mullaperiyar dam based on a detailed study conducted about the security of the existing dam. A special task force has prepared a DPR for constructing the new dam. The other studies/works included are model studies, dam break analysis, investigation for road way etc. Ministry of Environment Forest and Climate Change has approved Terms of Reference for Environment Impact Assessment study for the new Mullapperiyar Dam. The EIA study is under progress. Dam construction would be started only after obtaining all statutory clearances.An amount of 50.00 lakh is provided for the project during 2022-23.
Investigation of Irrigation Schemes
The objective of the scheme is investigation of new major and minor irrigation projects, preparation of project reports and also revision of project reports. The major activities include soil investigation works, desiltation study of dams, sedimentation study of various reservoirs etc. The sedimentation studies can be used for regulating the outflow of reservoirs.An amount of 220.00 lakh is set apart for the scheme during annual budget 2022-23.
Flood Early Warning System (FEWS)
Under the World Bank funded National Hydrology Project,IDRB is developing "Real Time Operation of Reservoirs integrated with flood forecasting and warning system for Periyar Basin".The accuracy of the forecasts depends on the real time hydro-met data received and the quality of topographical features. During 2022-23, it is proposed to establish more number of Real Time Hydro-Met stations and availability of high resolution (1m to 5m)DEMs.An outlay of 50.00 lakh is provided in budget 2022-23 for establishing the Flood Early Warning System (FEWS). The physical and financial progress of the scheme will be reviewed at the Secretary level and an action plan will be charted for completion of project.
Dam Rehabilitation and Improvement Project DRIP Phase II
DRIP Phase II, launched during 2019-20, received in principal approval from Central Water Commission. 15 dams are selected for Phase II - (Malampuzha, Neyyar, Walayar, Kuttiyadi, Kanjirapuzha, Chimoni, Malankara, Kallada, Pothundy, Meenkara, Chulliyar, Pazhassi barrage, Bhoothahankettu barrage, Mangalam, Karapuzha and Pamba). DSRP inspections were conducted for 9 dams and Project Screening Templates approved for 6 dams. The funding pattern is 70:30 (70% World Bank loan and 30% state share). Government of Kerala has accorded DRIP phase II Administrative Sanction for 24000.00 lakh. For the activities under DRIP Phase II, an outlay of 3000.00 lakh is provided during annual budget 2022-23.
Benchmarking of Irrigation system
Benchmarking is a management tool helps in the evaluation of individual irrigation system and suggests methods to improve the system. It is used to compare the processes with the best practices and to adopt suitable ones. In the irrigation system, this would improve the efficiency of the system and result in savings in water usage. Bench marking for effective irrigation management is introduced with the objective of identifying the best management practices, prioritizing and evaluating rehabilitation and remodeling of projects with an objective to improve irrigation efficiency. Benchmarking of the irrigation systems in Kerala would go a long way in increasing the efficiency of the system. Interventions for repairs, rectifications and improvements would be prioritized based on the report of the benchmarking exercise. All the completed irrigation projects would be brought under benchmarking process in a phased manner.During 2022-23, it is proposed to take up benchmarking of Chitturpuzha, Malampuzha and Peechi irrigation Projects along with a decision support system for effective distribution of water for irrigation.An outlay of 40.00 lakh is provided in budget 2022-23.
Formation of River Basin Organisation
The basin wise development of all the rivers of the state shall be taken up in a phased manner which includes survey and demarcation of rivers, river side afforestation, works related to pollution abatement in rivers, riverside protection works, assessing carrying capacity etc. A river basin approach has to be followed in assessing the availability of water resources and their optimal utilization integrating it with the various needs in the command area. It will address the issues of soil conservation, pollution control, flood control, optimum usage of water resources in the river, sand budgeting of rivers in Kerala and long term conservation of rivers. To have a holistic approach for the rejuvenation of a river basin, the impact of sea erosion/ accretion needs to be assessed. To analyse the behavior of coastal area and its impact on the river basin, data collection of coastal areas and its connected activities,are proposed under the scheme.An outlay of 100.00 lakh is provided during annual budget 2022-23 under the scheme. The physical and financial progress of the scheme will be reviewed at the Secretary level and an action plan will be charted for completion of project
Post Facto Evaluation Studies
It is observed that there has been undue delay in implementation of irrigation projects in the state and the outlay is provided to conduct monitoring (concurrent as well as final evaluation) of all ongoing and completed irrigation projects, major, medium and minor including micro irrigation implemented in the state through Third Party agency. Monitoring and Evaluation of Irrigation Projects including concurrent monitoring will help to improve the efficiency of irrigation projects. An independent and highly competent accredited agency, preferably in the government sector (other than Kerala Government) or Public Sector Undertaking outside Government of Kerala, which has substantial experience in the field, will be selected through competitive bidding. This agency will do the concurrent evaluation of all irrigation projects, and will undertake the final evaluation of completed projects. The indicative areas to be covered in the M&E procedure include adherence to time and cost, project appraisal and quality of DPR, different processes involved in formulation and implementation, and the accrued/accruable benefits of the projects may be evaluated vis-a-vis the initial objectives of each project. Through this study the socio economic benefits from the irrigation projects will be analysed in detail. An amount of 70.00 lakh is earmarked for this purpose in budget 2022-23. The progress achieved in this regard will be reviewed at the secretary level as the scheme is in vogue from 2021-22.
