SAUNI Yojana Aji 1 Dam: Gujarat Government Initiates Narmada Water Pumping to Fill Reservoir and Solve Rajkot’s Water Shortage Within a Month

Introduction

In a decisive move to secure long-term drinking water availability for over 18 lakh residents across Saurashtra’s commercial hub, the Gujarat state government has officially initiated the pumping of Narmada water into the Aji-1 reservoir under the landmark SAUNI Yojana Aji 1 Dam project. The state Irrigation Department, in close coordination with the Rajkot Municipal Corporation (RMC), activated high-capacity pumping stations along the SAUNI Link pipeline network. This operational push aims to completely fill the city’s primary reservoir within a month, guaranteeing an uninterrupted municipal tap water supply well into the upcoming summer season.

This water management milestone comes as a major relief to urban households, industrial units, and commercial establishments across Rajkot. Although recent monsoon rains provided initial storage, localized rainfall deficits in the Aji river catchment left the dam’s water level below full capacity prior to the peak festive and winter demand cycles. Recognizing the threat of mid-season water rationing, the state government approved the bulk allocation of Narmada floodwaters, ensuring that raw water supplies at the Aji-1 impoundment are fully restored.

The commencement of bulk water transfers underscores the strategic value of Gujarat’s grid-connected water infrastructure. By transferring Narmada waters directly into urban surface reservoirs via high-pressure underground steel pipelines, civic authorities are eliminating the threat of drinking water cuts across all municipal wards. As pumping operates around the clock, this initiative stands as a testament to proactive governance, infrastructure engineering, and long-term urban sustainability for Rajkot.

What is SAUNI Yojana Aji 1 Dam?

The SAUNI Yojana Aji 1 Dam initiative refers to the specific bulk water transfer pipeline link connecting the Narmada canal grid to the Aji-1 Dam under the Saurashtra Narmada Avtaran Irrigation (SAUNI) Yojana. Envisaged as a multi-stage water transfer project, the SAUNI Yojana was designed to divert surplus Narmada floodwaters through a network of underground trunk pipelines to fill 115 major dams across 11 water-scarce districts of Saurashtra.

Under this system, heavy-duty electrical pumping stations lift Narmada water and transport it through pressurized steel pipe canals laid deep underground. The Aji-1 Dam, located on the southeastern outskirts of Rajkot, serves as the primary intake source for the city’s municipal water treatment facilities. Connecting Aji-1 directly to the SAUNI pipeline network transforms the rain-fed reservoir into a multi-source impoundment that can be replenished on demand.

Why This News is Important

The official initiation of Narmada water pumping into Aji-1 Dam holds immense economic, social, and civic importance for Rajkot and the broader Saurashtra region. First, securing water availability at Aji-1 eliminates the threat of municipal water cuts, alternate-day supply schedules, or reduced distribution pressure across the city’s 18 municipal wards. Assuring daily 20-minute municipal tap water distribution provides complete domestic peace of mind to urban families.

Second, the month-long filling timeline protects the municipal corporation from spending millions of public funds on emergency water transport, private water tankers, or deep borewell drilling. Having a filled surface reservoir guarantees that water filtration plants at Aji operate at peak capacity, delivering high-quality treated drinking water to homes.

Finally, the project provides stability for Rajkot’s rapidly expanding commercial and industrial sectors. As an industrial hub famous for auto-ancillaries, forging, engineering, and kitchenware manufacturing, Rajkot’s economy requires stable municipal infrastructure. Ensuring long-term water security boosts investor confidence, supports local businesses, and guarantees sustainable urban growth.

Background Information

Historically, Rajkot was known as a chronically water-scarce city located in a semi-arid geographical zone. The city’s main surface water reservoirs—Aji-1, Nyari-1, and Bhadar—relied entirely on erratic monsoon rainfall within their localized river catchments. During drought years or seasons with uneven rainfall, reservoir levels dropped precipitously, forcing the city administration to import drinking water via special water trains from Gandhinagar or execute severe water cuts.

To permanently break this cycle of drought, the state government conceived the ₹12,000-crore SAUNI Yojana. Instead of constructing conventional open canals that cause high land acquisition costs and transit evaporation losses, SAUNI utilized underground pipe canals equipped with high-capacity pumping stations.

Detailed Breakdown of the Bulk Water Transfer Operations

The mechanical and hydraulic execution of pumping Narmada water into Aji-1 Dam involves coordinated engineering across the SAUNI pipeline grid. The process begins at the main Narmada canal diversion points, where excess floodwaters are diverted into large-diameter underground feeder pipes.

Submersible electrical pump houses—consuming heavy electrical power to maintain high flow pressure—push the water across miles of undulating terrain through dedicated trunk lines. The pipeline terminates directly at the discharge gates on the bank of Aji-1 Dam, where freshwater cascades into the storage basin.
