  "content": "Work on the third and fourth phases of the ambitious Dewas water project is moving forward rapidly to bolster water infrastructure and meet the long term drinking water requirements of Rajasthan. Executed under the leadership of Chief Minister Bhajan Lal Sharma, the project entails building massive storage dams and long underground tunnels across challenging terrain. Once operational, the integrated network will supply approximately 1000 Mcft of additional water each year to Udaipur, reinforcing the urban municipal supply while helping preserve optimal water levels in Lake Pichola and Fateh Sagar Lake.\n\nFrom an infrastructure perspective, the Dewas development represents a pivotal step in expanding water storage capacity and managing surface water resources efficiently in Rajasthan. By engineering an interconnected network across rugged topography, surplus water will be transferred smoothly from one reservoir to another rather than running off unused. This engineering layout directly addresses the drinking water requirements of urban populations while sustaining lake based tourism activities that form the economic foundation of the lake city.\n\nDewas Phase 4: Ambawa Dam and 4.15 Km Transfer Tunnel\nUnder the fourth phase of the project, designated as Dewas-4, construction is underway on a dam with an impoundment capacity of 390 Mcft near Ambawa. Water captured within this reservoir will be channeled through an underground tunnel measuring 4.15 kilometers in length to feed directly into the Dewas Phase 3 infrastructure.\n\nThis design focuses on elevating water harvesting and inter-basin transfer efficiency, maximizing the utility of seasonal rainwater gathered across the catchment. The combination of dam storage and deep tunneling plays a central role in tying diverse project segments together into a synchronized hydrological framework.\n\nDewas Phase 3: 703 Mcft Nathiathal Reservoir and 10.50 Km Tunnel\nUnder the third stage of the venture, or Dewas-3, a larger reservoir with a storage capacity of 703 Mcft is being erected in the vicinity of Nathiathal. The collected reserves will be transferred through an extensive 10.50 kilometer long tunnel to connect seamlessly with the Dewas-2 network.\n\nTogether, the 4.15 kilometer tunnel in Phase 4 and the 10.50 kilometer tunnel in Phase 3 create a subterranean conduit network spanning 14.65 kilometers. By linking isolated storage dams and transfer channels into an integrated distribution pipeline, the project constructs a robust mechanism for regional water management across the Udaipur belt.\n\nPreserving Water Levels in Lake Pichola and Fateh Sagar\nUpon final commissioning of Dewas-3 and Dewas-4, the projected inflow of 1000 Mcft of water per year will substantially de-risk municipal supply networks in Udaipur. Beyond household pipelines, this steady supply will serve as an essential lifeline for Lake Pichola and Fateh Sagar Lake by preventing depletion during dry summer spells.\n\nBoth lakes define the cultural identity and tourism appeal of Udaipur. Maintaining healthy water levels throughout the year directly protects hospitality, boating operations, and travel enterprises, ensuring that businesses and workers dependent on local tourism can operate without seasonal water distress.\n\nStrategic Infrastructure Against Urbanization and Water Scarcity\nWith ongoing population growth, expanding urban centers, and escalating municipal demand across Rajasthan, dependable storage and transfer infrastructure has become a necessity. The construction of twin reservoirs and extensive rock tunnels under the Dewas initiative directly addresses these structural vulnerabilities.\n\nWhen completed, the venture is expected to establish durable water security for Udaipur for years to come. Planners emphasize that the full realization of these projections will ultimately rest on timely civil construction, rainfall patterns in the catchments, and regular operational maintenance of the transfer systems.\n\nWhat this means for you\nThe execution of this water infrastructure project ensures consistent drinking water delivery and economic security for residents and business owners in Udaipur.\n\n• In Udaipur: Urban residents will receive an additional 1000 Mcft of municipal water annually. This steady allocation will prevent severe drinking water shortages during hot summer months.\n• For Local Tourism: Lake Pichola and Fateh Sagar Lake will maintain healthy water levels throughout all seasons. Stable water tables will safeguard boat operations, lakeside hospitality, and related livelihoods without seasonal disruption.\n• Water Storage Capacity: The addition of two new reservoirs will create 1093 Mcft of collective storage capacity. This enables the state to impound seasonal runoff effectively rather than letting it escape unused.\n• Inter-Basin Transfer: The 14.65 kilometers of transfer tunnels will facilitate seamless water movement between disparate catchments. This subterranean network guarantees water reliability even during irregular rainfall cycles.\n\nWhy this happened\nThe third and fourth phases of the Dewas project were initiated to address rapid urban expansion, rising water demand, and seasonal water depletion in Udaipur lakes.\n\n• Growing Urban Demand: Sustained population growth placed acute pressure on existing local water sources. Securing long term municipal drinking water required importing surface water from adjacent catchments.\n• Lake Level Depletion: Erratic monsoon rains frequently left Lake Pichola and Fateh Sagar critically depleted, threatening both municipal supplies and tourism revenue. Connecting the lakes to upstream reservoirs ensures continuous replenishment.\n• Undeveloped Catchment Runoff: Substantial rainfall in surrounding rugged hills was previously lost due to insufficient storage infrastructure. Building dedicated reservoirs at Ambawa and Nathiathal allows the state to capture and transfer this seasonal surplus.\n\nQuestions & Answers\n\n1. How much additional water will Udaipur receive from Dewas Phase 3 and 4?\nUpon completion of both phases, Udaipur will receive approximately 1000 Mcft of additional water each year.\n\n2. What infrastructure is being constructed under Dewas Phase 4?\nDewas Phase 4 includes a 390 Mcft storage dam near Ambawa and an interconnected 4.15 km long transfer tunnel.\n\n3. What are the core technical specifications of Dewas Phase 3?\nDewas Phase 3 features a 703 Mcft reservoir near Nathiathal along with a 10.50 km long water tunnel.\n\n4. Which major lakes in Udaipur will benefit from this project?\nThe project will help maintain essential water levels in Lake Pichola and Fateh Sagar Lake.\n\n5. What is the total length of the tunnels being built under these two phases?\nThe combined length of the tunnels across both phases totals 14.65 kilometers (4.15 km in Phase 4 and 10.50 km in Phase 3).",
