The West Coast Canal from Kottapuram to Kollam was declared as National Waterway No.3 vide National Waterway (Kollam-Kottapuram stretch of West Coast Canal and Champakara and Udyogmandal Canals) Act 1992 ( 33-F of 1992 ) and notified on 1st Feb. 1993. From Kottapuram to Kollam including Champakara and Udyogmandal canals has a navigable length of 205 kms.
This waterway comprises of natural lakes, back-waters, river sections and man-made canal sections. The Champakara and Udyogmandal canals link industrial centers of Ambalamugal and Udyogmandal with the Kochi port. On the main West Coast Canal between Kollam and Kottapuram, the Kochi Edapallikota (120 kms) stretch was opened for cargo movement during November 1994 consequent to improvement works carried out by IWAI.



Fairway Development:
Fairway development works including maintenance dredging, and maintenance of 24 hrs navigational aids are continued during 2008-09. Bank protection works in some stretches were completed in 2007-08 and these were also taken up in some critical stretches of Champakara and Udyogmandal canals during 2008-09.
Capital dredging for widening and deepening of canal between Kochi and Kollam was started in first phase during 1997-98. In Kochi – Kottapuram stretch, capital dredging was started in 2nd phase during September 2002. Work in Kochi-Allapuzha sector was completed and in Kochi-Kottapuram sector (30 km) dredging was completed except 4.83 km. But in the remaining reaches, it got delayed due to various problems such as disposal of dredged material, fishing nets, local issues leading to contractual problems etc. Out of entire length of 205 km of the waterway, the total shoal length has been estimated as 87.16 km out of which 59.75 km has so far been dredged and 24.49 km remains to be dredged. The total quantity which was to be dredged for deepening the entire shoal length was worked out as 40.33 lakh m3 out of which 23.98 lakh m3 has been dredged and 16.35 lakh m3 remains to be dredged. For completion of this capital dredging (which also includes widening of the narrow sections which necessitates removal of boulders, coconut trees, old bank protection etc), a scheme at a cost of Rs.89.74 Cr was approved by the Govt. and tenders were invited to take up this work.

Terminals at seven locations namely Kottapuram, Aluva, Maradu, Viakom, Thaneermukam (Chertala), Trikkunnapuzha and Kayamkulam have already been constructed.Under PDO/PDC mechanism, the PDO was entrusted the work of formulating a project for operation and maintenance of these terminals as a PPP project. The PDO had made a field visit and collected relevant data and they were in the process of formulating the project. Construction of 8th terminal at Kollam by CPWD was also in progress. For providing facilities for mechanical handling at these terminals, 8 mobile cranes and 8 fork lifts were procured and provided at each terminal.

Navigational Aids:

Project for providing and maintaining 24 hrs navigational aids by way of buoys and lights had been completed during 2007-08 and now the entire waterway has the facility for 24 hrs navigation which was maintained during 2008-09.3.64 In view of the development of International Container Transshipment Terminal at Vallarpadam in Cochin Port area, there is a tremendous potential for transport of containers through NW-3. Keeping this in view, IWAI in collaboration with Cochin Port Trust initiated the process of construction of Roll on-Roll off cum Lift on –Lift off IWTterminals at Willingdon and Bolgatty islands on NW-3 in Cochin port area.Cochin Port Trust (CPT) is presently handling 3 lakh TEU containers per annum through its existing facilities at Willingdon Island. On commissioning of Vallarpadam ICTT, the quantum of containerized cargo would substantially increase. The traffic will reach at Willingdon Island and move to ICTT by barge/ RO RO service by making use of IWT. Dedicated IWT terminals on NW-3 will provide the requisite infrastructure and landing facilities for containers in transit through NW-3 from IWAI’s existing terminals to ICTT, besides providing facility for transporting containers to Vallarpadam ICTT through RO-RO barges from Cochin Port.
