UIG Scheme under JNNURM

UIG Scheme under JNNURM

  While the pace of urbanization has been on the rise with the size of absolute urban population increasing year after another, leading to increased demand for urban infrastructure and services, the shortage of resources of the municipal governments became too acute, notwithstanding invocation of the 74th Constitutional Amendment Act of 1992. Most municipalities are starved of resources on account of their inability to effectively use their revenue raising power, particularly relating to property.

The sectors and projects eligible for assistance under JNNURM Sub Mission-I, i.e. Urban Infrastructure & Governance, include water supply, sanitation & sewerage, solid waste management, drainage, urban transport, heritage conservation, urban renewal and the like. Essentially, the programme focuses on up-gradation of basic infrastructure and services.
 
     
  UIG Scheme for improvement of drainage system in Panihati and adjoining municipalities have been initiated as given bellow:  
     
  Transmunicipal drainage scheme on removal of drainage congestion within Khardah, Panihati, North Dum Dum, Dum Dum and South Dum Dum  
     
  Major components  
     
 
  1. Construction / re-sectioning of lateral surface drains and underground storm water conduits in some areas.
  2. Resectioning of Khardah Khal
  3. Resectioning and lining of Nadikul, Sonai, Udaypur, Sultanpur, Birati Khal/drains
  4. Construction of pipe bridge over Udaypur Nullah
  5. Pumping Station at South Dum Dum Municipality near VIP Road

  PROJECT OUTLINE:  
     
  Considering the large number of people who will be benefited, this project has been chosen as one of the 57 projects prioritized out of the initial 109 projects identified for assistance under JNNURM. Out of these, 15 projects have been shortlisted for immediate assistance and this project figures in that selective list too.

Marvel of the project is that it has not been designed to strive for something too ambitious. It has taken cognizance of ground realities and has strived to make use of the existing system to attain its objective. For example, the masonry drains constructed by different municipal authorities for several kilometers and passing through narrow roads obstruct the flow of water. Neither is it possible to lay bigger diameter storm drains nor is it practicable to dismantle the existing ones for economic consideration. The objective of this scheme is to implement these missing links, as well as to enlarge the constrictions to ease bottlenecks. The scheme therefore has been framed accordingly, to ensure smooth outlet of monsoon run off from each municipal town as well as adjoining areas. Taking stock of the bottlenecks has been done through empirical observations of the waterlogging that has happened in the yesteryears. Thus, this may be treated as a surrogate hydraulic modeling exercise for this project. Only this exercise is even better as it has accounted for all the parameters and intangibles involved in the drainage system, which in a theoretical exercise might have been omitted.

During monsoon, the drainage inadequacies of the areas under added areas of Khardah, Eastern part of the B. T Road within Panihati Municipality, major parts of North Dum Dum, Dum Dum and South Dum Dum get highlighted as causes mass sufferings. All the afore-mentioned five municipalities are inter-dependent upon one another for discharging their drainage water to the outfalls, namely Khardah Khal, Udaypur nallah, Sonai nallah, Birati LL2K Khal, Bagjola Khal, Fateshah Khal, Nowi Khal etc., as because the surface runoff of one municipality enters the adjacent municipality to reach the outfall. So in absence of proper drainage system all the above five municipalities suffer from acute drainage congestion leading to massive water logging during rainy season.

The existing drainage system lost the hydraulic adequacy to carry massive quantum of storm water towards out fall. Moreover, for want of lateral drains the water in many areas get stagnated for days. Some portions of the outfalls require renovation, desiltation, lining etc.

It has been found that the drainage problem of the above five municipalities can only be solved by implementation of a trans-municipal scheme involving improvement of branch channel, construction of lateral drains to reach the trunk main, desilting of existing drains, khals, outfalls, construction of culverts / vents, pipe bridges, construction of lifting stations, diversion of surface run off to other outfalls etc.

It is felt, and with justifiable reason too, that after due implementation of this drainage scheme in such high valued residential, industrial, commercial areas within the above five municipalities, population of about six lakhs will be directly benefited to a great extent and their sufferings will be lessened during monsoon months. It goes without saying that the system will function even more smoothly in the lean months.

It is expected that on implementation of the scheme, Khardah, Panihati, North Dum Dum, Dum Dum & South Dum Dum areas will be relieved from water logging problem to a considerable extent. But the major out let of the area is Bagzola Khal, which has to be revitalised.
