Agencies/Institutions involved in implementation of the project

  • Tata Consulting Engineers
  • Shah Technical Consultants


The Scope of the assignment is to prepare DPR for each Municipalities for the improvements of water supply distribution system viz, study the existing system including distribution network, availability of storage capacity, inequity in distribution, inadequacy of storage capacity, staging height of service reservoirs,  non-optimal  service reservoir locations, defects in the pipes and suggest measures to ensure daily and equitable water supply to the consumers. The scope also includes preparation of bid documents for the suggested improvement works and the Investment plan.

Chennai Desalination Project

Chennai city with a population of 75 Lakhs has water demand of approximately 1500 MLD.  Chennai is dependent on rainwater and surface water resources to meet this demand. In order to supplement the available resources, Government of Tamil Nadu in the year 2004     decided to implement a mega water project based on desalination.  The capacity of the desalination project was envisaged at 300 MLD along with associated piping of 50km and a power project of 100 MW

TWIC was engaged by Government of Tamil Nadu to carry out the pre-feasibility study of the project.  TWIC developed and prepared the report, which addressed the following issues:

  1. Selection of project sites
  2. Technology assessment
  3. Preliminary technical and commercial evaluation.


These reports formed the basis for implementation of the desalination projects in Chennai

Industrial Effluent Treatment & Water Reuse Projects

Tirupur Textile Effluent Management Project, Tirupur

Client: Tirupur Textile Dyeing Industries

TWIC assisted nine Common Effluent Treatment Plants in development of zero discharge solution for the bleaching and dying units in Tirupur. The total effluent treatment capacity of these nine CETPs is 53,000 cum per day, forming the majority of the effluents generated in Tirupur. The cost of this project was INR 4200 millions.

The scope of work undertaken by TWIC was preparation of detailed project reports, selection of technology and project specification, design engineering, procurement of contractor, arranging finance for the project and implementation supervision. The components of the ZLD CETP are Pipeline for effluent conveyance, Pre-treatment works, Reverse Osmosis plant, Evaporator plant, and Recovered water distribution system.

TWIC has also developed an  alternate technology called “Treated Brine Reuse Technology” which substantially reduces the dependence  on evaporator.  This has been successfully demonstrated at Arulpuram CETP and  is now being implement in the remaining TWIC developed CETPs.

Implementation of Zero Liquid Effluent Treatment Project for tannery cluster

Client: Ambur Economic Development Organization Limited

Project Management services for Zero Liquid Discharge (ZLD) based 3 Common Effluent treatment plants with capacities ranging from 1 MLD to 4 MLD (combined capacities of 7.2 MLD) in Ambur and Vaniyambadi Tannery cluster. These CETPs have Membrane Bio-Reactor as pre-treatment for RO systems and Evaporator for RO reject management.

The project cost of approx. Rs. 100 Crores was financed through a mixture of Government grant (50%) commercial loans (25%) and industry contribution (75%)

Technical and Commercial Feasibility for Development, Financing, Implementation and Operation of Zero Liquid Discharge Effluent Project for paper and Pulp effluent

Client: Tamilnadu Newsprint and Papers Limited, Karur

TWIC had entered in to an agreement for Preparation of Technical and Commercial Feasibility report as a precursor for Development, Financing, Implementation and Operation of Zero Liquid Discharge Effluent Project for paper and Pulp effluent.  As part of the project TWIC has carried out  Design, Implementation and Operation and Maintenance of a Pilot plant.

Currently the 120 m3/d pilot plant has been successfully commissioned and trials are is under progress

Marine Outfall Facility for treated effluent at Barndix Textile Park, Vizag, AP

Client: Brandix India Apparel City

Brandix Apparel City was being developed as a SEZ for attracting textile investment near Visakhapatnam.  The project envisages a treatment and disposal system for 45 MLD of textile effluent.

While the treatment system was developed by Brandix, TWIC was mandated to assist in development of a marine disposal system consisting of 6.5 km of on-shore segment and 2.5 km of offshore segment which consists of 560mm OD, PN-6, PE100 Onshore pipeline, 6143m long with additional 3744mm for future operation and offshore part of 560mm OD, PN-8, PE100 pipeline, 250m long along with diffuser system at 20m water depth for the outfall system.

The cost of the project is Rs. 21 Crores. The project has been completed and commissioned.

Operation and Maintenance

Tirupur Textile Common Effluent Treatment Plant at Tirupur

Client: Tirupur Textile Dyeing Industries

O&M services for Zero Liquid Discharge (ZLD) based nine Common Effluent treatment plants with capacities ranging from 3 MLD to 11 MLD (combined capacities of 53 MLD) in Tirupur textile cluster. The effluent from various industries collected, metered, and conveyed to the Common Effluent Treatment Plant (CETP) for treatment and recovered water distributed back to the industries for processing. These CETPs are equipped with Pre-treatment system (Biological Oxidation system based on Activated Sludge Process), Reverse Osmosis system and Mechanical Evaporator for RO reject handling.

TWIC has well  qualified and experienced team of Managers, Engineers, Chemists, Operators and Technicians who man the CETPs round the clock.
