Recent Development

By the end of the 1990s, the planning authority of Navi Mumbai initiated private participation in the developmental activity of Navi Mumbai.

A new railway link between Nerul and Uran is under construction and the portion of this line from Seawood to Ulwe is at an advanced stage of construction.[4] Kharghar and Panvel are experiencing major infrastructural developments due to their proximity to the proposed Navi Mumbai International Airport.

Also a latest development known as 'One Time Planning' with an estimated budget of 12,821 crores is underway to transform Navi Mumbai on the lines of the Mega Cities of the world.

CIDCO

When Navi Mumbai was created in 1970s, CIDCO was the only authority that looked after the development and maintenance of the city. CIDCO prepared a developmental plan for Navi Mumbai covering 95 villages.

Kokan BhavanFor the first ten years of the project CIDCO acted as the planning and administrative body, and as the developer and builder for the project. Taxes on property, land, commercial and water were payable to CIDCO. The 14 nodes which CIDCO created were named Airoli, Ghansoli, Kopar Khairane, Vashi, Sanpada, Nerul, CBD Belapur, Kharghar, Kamothe, New Panvel, Kalamboli, Ulwe, Pushpak and Dronagiri. Each of the nodes is divided into smaller groups called sectors.

Initially only Vashi, Nerul and CBD Belapur were developed by CIDCO with housing, schools and community centre roads. But after the arrival of the harbour railway line extension in 1990s, there was an increase in population. CIDCO shifted its development plan to nodes like Kharghar, Kamothe, New Panvel, and Kopar Khairane. In its new development plan, CIDCO land was allocated to builders for housing. CIDCO only provided basic infrastructure like roads, water and electricity, these nodes were developed mostly by private builders according to the CIDCO plan.

Transportation

Within each node, the auto rickshaw is the preferred mode of transportation. Taxis operating from designated taxi stands provide the means to travel further to destinations. Taxis charge a fixed rate approved by the R.T.O.

The Mumbai suburban railway network covers most of the populated region of the city. The most important suburban stations are Vashi, Nerul, Belapur & Panvel. The stations are planned as major railway junctions. Panvel is the only mainline station and also the busiest railway station of Navi Mumbai. All outstation trains halt here for time periods varying from 5 to 20 minutes. It is an important junction, railway lines come and meet here and it is connected to almost all parts of India. A new broad gauge line is functional between Karjat & Panvel and currently plies three express trains.

Brihanmumbai Electric Supply and Transport (BEST) & Navi Mumbai Municipal Transport (NMMT)

Buses travels all over Mumbai, Navi Mumbai, Thane, Kalyan-Dombivli-Badlapur, Panvel-Khopoli, Uran, Bhayandar etc. NMMT AC Volvo and BEST AC Kinglong buses are available from Mumbai to Navi Mumbai and vice versa.

The 10 km long Palm Beach Road of six lane connects Vashi to CBD Belapur running parallel to the creek. It is a twin of the Marine Drive.

Navi Mumbai boasts the most advanced port in India, Jawaharlal Nehru port at Nhava Sheva near Uran. It is well connected with road, and handles approximately 65% of India's container traffic.

Navi Mumbai is located just 30 km away from Chatrapati Shivaji International Airport.

Services

There are adequate utility services, banks, restaurants, malls, multiplexes and other shops in Navi Mumbai. Vashi boasts several shopping malls such as Center One, Palm Beach Galleria, Citi Center, Raghuleela Mall and Inorbit Mall. Palm Beach Road, Nerul, and Kharghar are also witnessing the construction of malls like lil world and glomax and multiplexes. Throughout Navi Mumbai supermarkets and malls like Apna Bazaar, More, Spencer's, Reliance Fresh, Spinach and Fairprice cater to the shopping needs of the residents. DMart has launched five hypermalls in Navi Mumbai.

Leading banks such as the State Bank of India, Union Bank, Saraswat Bank, Bank of Baroda, Bank of Maharashtra, Bank of Hyderabad,Citibank India, ICICI Bank, and HDFC Bank have their branches and ATMs around Navi Mumbai. The Reserve Bank of India has served the people of Navi Mumbai since 2001.Navi Mumbai has some three- and five-star hotels.

Sports

Cricket is the prevalent sport in the city. Navi Mumbai has its own International Cricket Ground in Nerul called the DY Patil Stadium which hosted 3 IPL T-20 matches and the IPL T-20 Cricket Final. It is said that this stadium is one of the best in India.

Navi Mumbai has an Olympic-size swimming pool at Nerul. CIDCO has proposed two 18-hole golf course academies at Nerul and Kharghar. There are plans to have sports facilities in the proposed 80 hectare central park being developed in Kharghar. The CIDCO has also constructed an 11-hole golf course at Kharghar.

Water Supply

CIDCO has planned its own water supply project schemes at Hetawane, Morbe and Balganga. CIDCO has allocated 12% of its expenditure on physical infrastructure towards the provision of water supply in Navi Mumbai.

Water supply infrastructure has been planned by dividing each node into sub-sectors where ESR and GSR are provided to fulfill the demand of residents. CIDCO has provided 45 ESRs, 48 GSRs, 8 MBRs and 10 HSRs of capacity 67.80 MLD, 87.30 MLD, 57.00 MLD and 22.25 MLD respectively. The total storage capacity thus is 235 MLD which is more than one day's demand of water.

1. Four lakh metres of pipeline to supply water.
2. Water Supply to Navi Mumbai is supplied through the Morbe Dam, which is owned by the Navi Mumbai Municipal Corporation (NMMC). It has the capacity to provide 450 MLD water, of which only 330 MLD is being utilised today.
3. The Hetawane Water Supply Project, which is owned by the Irrigation Dept., has also proved a boon. Laid with the help of JBIC, Japan through HUDCO, it has a capacity to provide 350 MLD water, out of it, 150 MLD is being currently utilised by CIDCO. Now an additional 35 MLD is being sanctioned by the Irrigation Dept.
4. The Balganga Dam Project (350 MLD) is coming up by May 2014.
5. Other sources: MIDC (75 MLD; utilised by NMMC) and MJP (65 MLD; utilised by CIDCO for Panvel and Kalamboli).

Seawage Treatment and Drainage

Navi Mumbai is a pioneer in MMR that treats Seawage before discharging it into the creek. CIDCO has provided 1-2 Seawage Treatment Plants (STP) in each node. These are state-of-the-art C-Tech/SBR Seawage treatment plants which run on gravity and pumping mechanism. Standards of Maharashtra Pollution Control Board are met before the treated effluent is discharged.This treated effluent is used for landscaping and gardening. The extensive water requirement for the mega projects of Central Park and International Golf Course is also being met by the treated effluent of nearby STP in Kharghar

Detention ponds

CIDCO had a revelation with a study of the annual flooding at CBD Belapur's Artiste Village. That the channel carrying storm water through the colony was designed by considering a hydraulic gradient equal to the difference in invert at upstream to downstream ends. But with the diversion channel in spate, the required slope was unavailable, causing problems. The solution was achieved through a 16 Ha. m. surge volume to reduce 30% of the discharge. This area was created partly through excavation and partly through bunds, with an outlet of the desired discharge capacity. The detention pond thus formed also turned out to be a great picnic spot.

Holding ponds

Holding ponds is a hydraulic structure with a zero hydraulic gradient of water flowing into a holding pond in an extended channel, with a side weir constructed for discharge.

Two-tier drainss system, the lower tier drain catered to low-lying village storm water, which was then connected to a holding pond system. The upper tier drain independently carried storm water from the newly developed urban area.

Central overflowing channel

This process, the discharge from the developed area was diverted into a pond. A single discharge point at the pond periphery allowed the storm water to enter the pond. With it, two walls were constructed within the pond. This ensured that the pond started holding water after the river water level exceeded the predetermined level, keeping the pond empty for the remaining period.

Storm Water Management

Navi Mumbai experiences average annual rainfall from 2500-3000 mm which may extend to 5000 mm considering the catchment areas of hill ranges. Therefore disposal of rain water from the city area is a critical issue as during rainy season water gushes in from the surrounding areas. CIDCO identified following challenges while designing Storm Water Management for Navi Mumbai.

1. If the storm water is not properly disposed of, Navi Mumbai will face high occurrence of flooding due to high tide conditions.
2. In Navi Mumbai project area, about 20% land is low lying and prone to tidal submergence.
3. High of surrounding Parsik Hill ranges varies from 50 to 500 metres above MSL. The hill slopes are very steep.
4. Reclamation of the entire city area for the project may not be economically and environmentally feasible. At the same time disposal must not endanger the life of people. Based on these conditions, CIDCO identified two methods of reclamation.
5. Polder or Dutch Method of Reclamation (Non-Conventional Method) : This method involves construction of bunds (dykes) rising above Highest High Waterline along coast water line to block entry of tidewater on the area proposed to be reclaimed.
6. Second method is conventional which require raising of the level of low lying area by earth filling.
