SABARMATI RIVERFRONT DEVELOPMENT PROJECT

A Multidimensional Environmental Improvement and Urban Rejuvenation Project

… one of the most innovative projects towards urban regeneration in the world to make the city livable & sustainable (KPMG ) SABARMATI RIVER and AHMEDABAD
The River Sabarmati flows from north to south splitting Ahmedabad into almost two equal parts.
For many years, it has served as a water source and provided almost no formal recreational space for the city.
As the city has grown, the Sabarmati river had been abused and neglected and with the increased pollution was posing a major health and environmental hazard to the city.
The slums on the riverbank were disastrously flood prone and lack basic infrastructure services.
The River became back of the City and inaccessible to the public Ahmedabad and the Sabarmati :1672 Sabarmati and the Growth of Ahmedabad Sabarmati has always been important to Ahmedabad As a source for drinking water

As a place for recreation As a place to gather Place for the poor to build their hutments

Place for washing and drying clothes Place for holding the traditional Market And yet, Sabarmati was abused and neglected Sabarmati became a place Abuse of the River to dump garbage

• Due to increase in urban pressures, carrying capacity of existing sewage system falling short and its diversion into storm water system releasing sewage into the River. Storm water drains spewed untreated sewage into the river • Illegal sewage connections in the storm water drains

• Open defecation from the near by human settlements spread over the entire length.

• Discharge of industrial effluent through Nallas brought sewage into some SWDs. the river and abused Sabarmati • Illegal construction/encroachment of huts/slum on the river bed. Encroachments reduced the river’s flood carrying capacity

The river was inaccessible to the public SABARMATI RIVER FRONT DEVELOPMENT PROJECT

For implementation of
The Sabarmati Riverfront Development Project is a city level this Project: intervention. A Company has been set up by AMC in the

The objective of the river hydraulic study was to ensure for:
River width in such a way that, expected High Flood Level(HFL) in the River in its natural condition, does not significantly increase after it is constricted and trained.
Height of Retaining walls and Embankment in relevance to HFL
The Depth of Diaphragm wall to protect scouring of the Riverbed
Stability of existing bridges by protecting piers against increased velocity as per the design HFL River Hydraulic and Alignment

This may connect either side of the city area on North - South link.
The infrastructure created can accommodate at least six points on each side for station (as shown in the layout)
These points are well connected with the nearby city/suburbs .
The roots may be created in such a way that existing boating facilities should not get disturb.
Ahmedabad is not used to Water transport, it may require to promote this through various efforts.
There will be water in this stretch for most of the days, however during flood like situation, heavy storms in monsoon this can’t be operated. Finance as on 31/07/2014

It is made possible to retain surface water in the river all year round also utilized for boat rides etc.
The water recharges the ground strata extensively with storage of 12.5 million cubic meter river water.
Interceptor sewers and sewage diversion network has diverted more than 250 MLD sewage from the river and eliminated the pollutants.
Diaphragm walls in the bed of the river has protected from scour and stopped erosion of the river banks.
Retaining walls along both banks has made 202 Ha . land available for further development for the city and also contributed for flood protection.
The embankments on either side of the river has provided wide walkways, many other facilities and green space for the public with extensive tree plantation.
10000 slum dwellers residing on the riverbed have been rehabilitated and resettled in very good PAKKA houses.
Traditional user of River like washer men and unorganized vendors are now provided with well organized facilities.
Easy access to the river water through Ghats, Sairs/Ramps. Coverage of the Population

The Project: It has great impact on the urban rejuvenation and environmental improvement of the City. This cover whole Ahmedabad having population of six million .
Slum Dwellers: More than 10000 Project Affected Families i.e. the slum dwellers residing on the riverbed have been rehabilitated and resettled in very good PAKKA houses with all required basic civic amenities along with the community development. This has covered more than 50,000 population.
Informal Market: This is to cover the vendors as well as the buyers taking benefit of this including the vendor family is about 25,000 .
Dhobi Ghat / Laundry Campus: This has directly benefited 1,000 population i.e. family members of Dhobis.
Tourist: Being tourist destination, lot many tourist are also benefited. Key Learning from the Project

The abused river can be brought back;
To the city by utilizing the resources of the river itself
To convert the abandoned land of riverbed and nuisance at the centre of the City into; • people’s attraction, • tourist destination • to create infrastructural and recreational facilities • to transform the city more livable with o environmental improvement and o inclusive development. Cost Effectiveness of the Project

The total cost of the Project (till date) of Rs. 850 Cr is quite justifiable considering the components covered like;
Scour protection during flood in the river,
Protection of the banks,
Availability of huge land for various public purposes
Retention of water in the river
Various infrastructures. Moreover;
The amount spent is to be recovered from the development of less than 15% land.
Will ,generate other direct and indirect revenue in the form of taxes. Sabarmati back to Ahmedabad and Amdavadis back to the Sabarmati!
