Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
The leakage/ spill of oil in port and its surrounded area will be impact water quality.
The operational port with its entire infrastructure is going to build further pressure on the already depleted water
resources due to the tourists and other port staff and traders dependency.
Roads. The ponds and rivers could be impacted by solid waste disposal from the travellers. Travellers/tourists
people have the habit of throwing waste material carelessly to water bodies. This is more important because the
road users could be not only from various part of the country but also from all over the world
Rail. The only major planned cargo transport is containers. Other than the bunkering of fuel for the port
requirements no major hazardous cargo or liquid terminal is planned for this port. Therefore no spillages are
expected from either the incoming or outgoing container traffic.
5.2.3. Mitigation Measures
5.2.3.1. Mitigation Measures during Reclamation.
• While reclaiming the area, bunds will be provided with a suitable overflow facilities so that only clear
water will be returned to the sea. Ecology in the vicinity of the Port is not anticipated to be disturbed
during reclamation.
• Return seawater quality from the reclaimed area shall be monitored during reclamation phase.
Groundwater quality of nearby villages (Enayam) needs to be monitored during construction phase.
• An adequate drainage system will be provided at the site with separate collection streams to segregate the
storm run-off from roads, open areas, material storage areas, vehicle wash water and other wastewater
streams.
• No construction during rainy days or extreme climatic conditions. Suitable measures will also be taken to
prevent the washing away of construction materials into the drainage system.
• Contaminated storm water will be collected and conveyed to sedimentation tank for removing grit.
• The port Water Management Plan should be developed in order to secure the project sustainable water
balance and in the project region in the construction phase, including as main water source the
Thamirapani river and other artificial water sources in use as of today.
• A surface water monitoring program shall be implemented during the construction phase. Effective water
conservation measure should be followed:
• Implementation of rain water harvesting/ storm water management in the projection region.
• Regular monitoring of surface water for quality and quantity water needs should be limited through
recirculation and reuse, implementing closed-circuit systems from sedimentation ponds to the quarrying
process.
• Storm water should be separated from process and sanitary wastewater streams in order to reduce the
volume of wastewater to be treated prior to discharge.
• Providing water & wastewater treatment facilities at construction camp.
• A ground water monitoring program shall be implemented during the construction phase. .A study should
be initiated to investigate the change in hydro-geological conditions, the available aquifers and safe yield
levels. The phreatic aquifer should not be affected when aquifers are exploited.
• There can be rainwater harvesting and large borehole diameter where existing women bathing or washing
purely for boosting domestic requirements
