Nemmeli Desalination Plant, Tamil Nadu, India

100 MLD Nemmeli Desalination plant was introduced as solution to Chennai's drinking water shortage. Since its inauguration, fishers living close to the plant complained against environmental damage, coastal erosion and land use change.


Description:

Chennai counts with a desalination plant in Minjur, and Nemmeli was the second. Further plants are to be built. Coastal common areas used by native small scale fisherfolk for their livelihoods was occupied by the state owned Chennai Metro Water Supply and Sewerage Board for the construction of the 100 MLD (100 million litres day) Nemmeli Desalination Plant. During construction, a cofferdam was built to transport equipment from the ships to the project site. This blocked the littoral drift of sand, causing the coast line to erode. Lot of people lost their lands and houses so far because of the existing plant. Areas north of the project site has eroded, and the sea has advanced over 500m. This has led to large scale loss of livelihood spaces - to park boats, haul nets and dry fish while also causing material damage to living spaces close to the beach. The desalination plant has also been violating environmental conditions issued to them by discharging highly saline brine water on the beach, which mixes in the near shore water. This has led to intense salinization of near shore water, killing plankton and other organisms responsible for the health of the fish resources. As a result, fish catch in a 5 kilometer radius from the coastline has reduced as reported by local fisherfolk. The sea here has become a dead zone. Local fisherfolk were promised jobs which were later denied. Today, there are plans to expand the project.

Outcome
Project StatusIn operation
Development of alternatives:The following are the demands of the locals and EJos.
1. Follow environmental conditions issued, ensure discharge of brine at a particular depth decided with the consultation of fisherfolk
2. Halt plans for further expansion in the same area
3. Carry out beach nourishment work in areas affected by sea level rise
4. Construct Green Belt
5. Compensate for loss of ecology and livelihood
Do you consider this an environmental justice success? Was environmental justice served?:No
Briefly explain:Although people have been protesting the negative effect of this desalination plant, state wants to keep the plant operational and further expand the capacity is ongoing. This is an indication that further damage is probable, and this is not an EJ Success.
