Coastal Environment Monitoring & Conservation

Jamnagar Sewerage Treatment Plant Project

A sewerage project is proposed which would be carried out in two phases as per topography of the city of which Phase-I would be financed by the World Bank. By the completion of Phase-I, pollution of the sea waters would be stopped and by completing an additional sewerage treatment plant in Phase-II, the sewage of the city would be treated up to year 2040. By implementing the Sewerage Network and Sewerage Treatment Plant in Jamnagar, the sewerage water, after treatment, would attain the permissible stature of disposal into the seawater which would stop the degradation of marine life in the Gulf of Kachchh. Jamnagar Municipal Corporation (JMC), Marine National Park & Sanctuary (MNP&S) and Gujarat Pollution Control Board (GPCB) will work in co-ordination in which JMC would implement, operate and maintain the

sewerage project; MNP&S will supervise the positive effects on corals after the implementation of the project and GPCB will monitor the quality of treated water from the STP and sea water in the proximity of Marine National Park and the coastline near Jamnagar.

Goal

Development of Underground Sewerage System for the area under Jamnagar Municipal Corporation (Jamnagar City including Jamnagar urban Development Authority) for the conservation and management of coastal and marine biodiversity.

Objective

Establishment of an efficient Sewerage Treatment Plant in Jamnagar to minimize the impact of untreated sewage disposal on the coastal and marine environment thus leading to the conservation of coastal biodiversity such as corals and mangroves.

Establishment of 71 MLD Sewerage Treatment Plant.

Issues & Causes

  1. 1. Health Hazards Due To Open Conveyance and Industrial Development:

    The presence of industrial and commercial activities on a large scale, in and around Jamnagar, tends to have a strong impact on the ecological quality of the city. The concentration of industries such as foundries, electroplating units, brass parts, throbbing within the city and lack of basic infrastructure, particularly inadequate drainage conditions and bio-medical waste generation tends to take its toll on the environment. Issues related to water pollution, air pollution and pollution from waste are of much concern for the citizens. At present, the sewer lines have been laid in 4 drainage zones. In the remaining zones, sewerage system has not been completed and hence, no facility for collecting sewage exists. Conveyance of sewage through open drains creates unhealthy conditions within the city. Water logging in the open drains leads to increased incidences of mixing of sewage with drinking water as well as creation of mosquito breeding grounds.

  2. 2. Ground Water Pollution:

    As there are no sewage treatment plants, untreated sewage from the city is being discharged into the river Rangmati and Nagmati. Due to the pollution in the river, bore wells located close to it also get contaminated and ultimately leading to waterborne diseases during periods of water scarcity.

  3. 3. Pollution from Farm Produce:

    Untreated sewage is directly lifted by farmers cultivating along the bank of the rivers for irrigating their vegetable farms. In the process they themselves are at risk from pathogens in the sewage water. There is a possibility that some heavy metals which might get absorbed by the plants from sewage water could enter the food cycle.

  4. 4. Threat to Coastal Ecosystem:

    Untreated sewage discharged into river Rangmati and Nagmati finally meets the sea at the Gulf of Kachchh. The belt of sea adjacent to the Jamnagar coast has been declared as Marine Sanctuary. Thus the polluted water poses a threat to marine and other biological life. The Bird Sanctuary at Khijadia too, is at risk from the polluted river water.

  5. 5. Mixing of Storm Water with Sewage:

    The storm water channels are also used as conventional open sewage channels. During rains the drains overflow and people are exposed to storm water mixed with sewage. Thus it is essential to lay sewerage facilities in the city quickly.

  6. 6. Maintenance Of Drainage In Old City:

    Creation of underground drainage system in the fortified old city will be proposed in the Phase-II of the sewerage project. The entire sewage from septic tanks and waste water is discharged into open drains at present. Therefore trunk lines running parallel to river Rangmati are proposed to stop the pollution of the river waters by the sewage discharge from areas excluded from Phase-I.

Project Benefits

Intangible Benefits:

  • Better management and conservation of marine biodiversity

Tangible Benefits:

  • Reduced chances of contamination of the ground water and in the water supply pipelines leading to reduced incidence of diseases, improved health condition
  • Economic benefits to farmers by usage of treated sewage water for irrigation purposes and dried sludge as manure
  • Generation of permanent employment at STP site
