Dighi Industrial Smart City (Dighi Port Industrial Area): Master Plan

What is being planned, and where

The Dighi Port Industrial Area, spanning 6,056 acres across the Roha and Mangaon tehsils in Raigad district, is positioned as a key driver of industrial growth, leveraging its proximity to Mumbai and Pune. The DPIA falls in 9 villages in the Roha and Mangaon Tehsils with a total area of 2,400 Hectares identified for development in the first phase.

Following the historic decision by the Government of India on 28th August 2024, approving 12 industrial nodes/cities under the National Industrial Corridor Development Programme, the Secretary, DPIIT, visited the proposed DPIA site. Dighi Port Industrial Area (DPIA), located in Raigad District, Maharashtra, spans 6,056 acres and is strategically situated near Dighi Port, enhancing its connectivity.

Total planned area vs. area being built now — an important distinction

Different official documents cite different area figures because they describe different scopes and dates:

• Wider DPIA/MIDC envelope (2022 environmental clearance): the Dighi Port Industrial Area project is spread over 5,024 hectares in Raigad district, with a total investment/cost of the project of Rs.7360.46 crore per the MoEF&CC clearance letter.
• Notified smart-city footprint (August 2024 Cabinet approval): located 55 km east of Dighi Port, the industrial smart city will span 6,056 acres and involve an investment of Rs 5,469 crore in trunk infrastructure.
• First construction parcel: a total area of 2,400 hectares has been identified for development in the first phase, and MITL is a special purpose vehicle formed by the Government of India and the Government of Maharashtra to develop Parcel B of the Dighi Port Industrial Area in Raigad district.

In short: the ~5,024 ha figure reflects the larger long-run project envelope used in environmental clearance, while the 6,056-acre (~2,451 ha) figure is the area formally notified for smart-city trunk infrastructure funding in 2024 — and it is this area (via Parcel B) where physical construction is now underway, as of early 2026.

Land use and zoning

No single master-plan document with a percentage-wise land-use table for DPIA was found in public sources as of July 2026. The environmental clearance for the project does, however, identify functional zones within the site: Pharmaceuticals (non-API), Engineering and Food zone as well as Residential zone within the proposed MIDC area, including area development and land infrastructure like roads, water lines, storm-water drains, power lines, common sewage treatment plant, and solid-waste management facility.

A 50-metre buffer is planned around ecologically sensitive patches: patches of Reserve Forests are seen adjoining the proposed layout, and a green belt of 50 m is proposed around the Reserve Forest patches in order to ensure the integrity of forest area and to maintain the natural form of forest. The Tamhini Wildlife Sanctuary is located about 4.7 km to the west of the proposed site. Because no official percentage split (industrial/residential/commercial/open space) for DPIA specifically has been published, this page does not present a land-use percentage table — unlike, say, the nearby AURIC Shendra-Bidkin project, which is documented with a 60:40 industrial-to-mixed-use split.

Phasing and current construction status

The project is being rolled out in parcels rather than a fully published multi-decade phase schedule with fixed target years. What is confirmed:

• Ramky Infrastructure has secured an EPC contract worth Rs 14.01 billion from Maharashtra Industrial Township Limited (MITL) for infrastructure development works at the Dighi Port Industrial Area Phase 1 under the Delhi Mumbai Industrial Corridor.
• The project will be executed within 930 days from the appointed date, followed by a four-year operations-and-maintenance period starting from the commercial operation date, with possible extension by mutual agreement.
• Key components of the infrastructure package comprise road networks and allied structures, stormwater drainage systems, water treatment and distribution systems, sewerage infrastructure, recycled water distribution networks, power distribution systems and ICT utility ducts.

No officially confirmed target year for completing the full ~5,024 ha long-run envelope was found as of July 2026; only the Phase-1/Parcel-B trunk-infrastructure timeline (930 days from contract commencement) is documented.

Population and employment targets

DPIA's targets are expressed mainly in terms of jobs and investment rather than a resident-population figure:

• The project is anticipated to attract investments worth Rs 38,000 crore and create approximately 109,185 jobs.
• A separate account from the DPIIT Secretary's site visit put the number higher: with sectors like general engineering, food & beverages, pharmaceuticals etc. proposed to set up manufacturing units at DPIA, an investment of Rs. 38,000 crore is expected, creating employment opportunities for about 1,14,000 people. NICDC's CEO & MD described these as conservative numbers likely to rise given the site's strategic location and plug-and-play, walk-to-work infrastructure.
• An earlier, narrower estimate tied to the 2022 environmental clearance (covering a different, larger project scope) put direct industrial employment lower: the industries to be set up will result in employment of about 50,000, providing alternate employment opportunity to population in the Konkan Region.

Because these figures come from different years and slightly different project scopes, treat the ~1,09,000–1,14,000 range (2024 figures, tied to the ₹38,000 crore investment target) as the current official estimate, and the ~50,000 figure as an older, narrower estimate.

Planner, consultants and project structure

NICDC is the national nodal agency; on the ground, MITL — a special purpose vehicle formed by the Government of India and the Government of Maharashtra — is developing Parcel B of the Dighi Port Industrial Area. NICDC itself undertakes project-development activities like preparation of master plans, feasibility reports and detailed project reports across its industrial-city portfolio, and for Dighi specifically, consultants have been appointed for the preparation of Detailed Master Planning, Preliminary Engineering design, preparation of tender documents and handholding support. The named engineering/planning consultancy firm for DPIA has not been publicly disclosed in the sources reviewed as of July 2026.

Site supervision during construction and later operations is planned through MIDC: around 50 MIDC personnel will supervise the development, while around 300 MIDC personnel will be responsible for operation, maintenance and establishment activities once complete.

Environmental clearance and water supply

DPIA holds a Category-A environmental clearance: EC Identification No. EC22A031MH110208, File No. 21-41/2020-IA.III, dated 17/10/2022. The project is classed as Category-A under the EIA Notification, 2006.

Water supply is planned from a nearby river: a reservation of 102 MLD has been made available through the Irrigation Department from the Kundalika River, with a jackwell near Kamat village and a water treatment plant near Pahur village. Groundwater is not part of the supply plan: groundwater extraction in MIDC areas is not permitted for this project. Sewage is planned to be centrally treated: a common sewage treatment plant will be provided for the residential area, using a conventional activated-sludge process or sequential batch reactor with tertiary treatment to enable treatment to less than 5 mg/L BOD and recycling.

Where to find the official documents

Primary, official sources for DPIA planning material include:

• NICDC's project page for the Dighi Port Industrial Area (nicdc.in) — project overview and status updates from the nodal agency.
• The Ministry of Environment, Forest & Climate Change environmental-clearance letter for the Dighi Port master plan, hosted on the MIDC website and on environmentclearance.nic.in — gives EC number, conditions, water and sewage provisions.
• Press Information Bureau (PIB) releases on DPIIT/NICDC site visits, which carry official investment and jobs figures at the time of statement.
• Tender/EPC contract announcements (e.g., for Parcel B trunk infrastructure) via MIDC/MITL procurement notices and trade press, for construction-stage details.
