Solar Based Micro Irrigation Scheme at Aspur, Distt. Dungarpur and its O&M for a period of 8 years, Rajasthan | WRD

Project Purpose

The Solar Based Micro Irrigation Scheme at Bhabrana, Dolpura, and Vanvasa Anicuts in Dungarpur district aims to address the critical need for reliable and sustainable irrigation infrastructure in a region highly dependent on agriculture. With climate change and irregular rainfall patterns affecting crop productivity, the project aims to improve water accessibility for over 600 farmers cultivating more than 1000 acres of farmland.

Project Deliverables

1. Anicut Structures
   Three anicut structures are being constructed on the Som River at Bhabrana, Dolpura, and Vanvasa locations. These structures are designed to store river water, slow down surface runoff, and enhance groundwater percolation. Their primary role is to retain water locally and increase soil moisture in the surrounding areas, thereby improving the fertility and productivity of nearby farmland. The lengths of the Anicuts being constructed in the project are ranging from 261M to 431M
2. Intake Wells and Approach Bridge
   Adjacent to each anicut, dedicated intake wells are being developed to facilitate the withdrawal of stored raw water. These wells serve as the primary source for lifting water into the irrigation system, ensuring a reliable and controlled supply for downstream agricultural needs. An approach bridge is constructed to ensure accessibility to the intake well, facilitating regular maintenance and operational activities.
3. Electro-Mechanical Works
   State-of-the-art pumping machinery is being installed at each intake well. These pumps are responsible for lifting water into the main feeder pipelines. The system is equipped with necessary electrical controls and automation features to maintain energy efficiency and consistent performance across the irrigation network.
4. Main Feeder Lines
   Main water transportation is handled through Ductile Iron (DI) pipelines which form the backbone of the irrigation scheme. These pipes carry water from intake wells to the various junction points of the distribution network, ensuring high-capacity, pressure-resistant, and low-maintenance conveyance of raw water.
5. Distribution Network
   To reach individual fields efficiently, a distribution network of HDPE (High-Density Polyethylene) pipelines is being installed. This network spreads across the 1000-acre command area and is tailored to support micro-irrigation. It ensures equitable water delivery with minimal loss, directly impacting the productivity of more than 500 farmers with over 120 Connections being provided to farmlands.
6. Solar Power Station
   A solar power station is being set up as part of the project to generate clean, renewable electricity. The energy produced is integrated into the grid to offset the power requirements of the irrigation system. This initiative not only reduces dependence on conventional power sources but also promotes sustainability in the region. A total power generation capacity of 765Kw Solar Power Stations are being built across 3 different locations in the project.
7. Operation & Maintenance (O&M)
   A comprehensive operation and maintenance plan has been structured for an 8-year period. This includes routine upkeep, repairs, and monitoring of all civil, mechanical, electrical, and distribution components to ensure seamless functionality and long-term performance of the entire irrigation scheme.
