About Us

The Vatva Industrial Estate was established by Gujarat Industrial Development Corporation in the year 1960 in the south east direction of Ahmedabad City on Ahmedabad – Mehmadabad state highway to accommodate small and medium scale industrial units.

There are approximately 1800 units in this industrial Estate, out of which approximately 680 generate wastewater and have potential to cause water pollution. These include units manufacturing Pharmaceutical Products, Dyes, Dye-Intermediates, Pigments, Fine Chemicals and other organics. They also include Textile Process Houses, Rolling Mills and other Non Chemical Process Industries.

During the decade of 1990s, many industries started planning compressive treatment. However it was very difficult and techno-economically not viable to arrange for necessary treatment of wastewater by these units individually. There was also constraint of space to install Effluent Treatment Plants by these units in their premises. The most practical and cost effective approach was to establish a Common Effluent Treatment Plant for the treatment of effluent being generated by these units. In fact it was necessary to establish proper infrastructure to take care of the environment related aspects being faced by the individual industrial units in the estate. In order to fulfill these objectives the ‘Green Environment Services Co-operative Society Limited’ (GESCSL) was formed with the support of Vatva Industries Association and Gujarat Dyestuff Manufacturers’ Association. Initially there were 620 industrial units of GIDC Estate, Vatva, Ahmedabad as members. The GESCSL is managed by 15 members including Chairman, Vice Chairman, Hon. Secretary and Hon. Treasure.

The important aspects of CETP Project are briefly outlined below

  • Location: The CETP Site is located at Plot Nos.: 244-251, Phase: II, GIDC Estate, Vatva, Ahmedabad.
  • Land Area: The CETP and associated facilities are set up on the land area admeasuring   24328 sq. m.
  • Treatment Technology: M/s Advent Corporation, USA gave the process design based on the treatability study carried out by Sudarshan Chemical Industries Ltd., Pune. The detailed engineering was provided by M/s Sudarshan Chemical Industries Ltd., Pune.
    The construction of CETP was commenced in March 1996 and was completed in all respects including installation of mechanical and electrical components in May 1998. The CETP was immediately commissioned thereafter.
  • Project Cost: Initially the common facilities for the collection, treatment (CETP) and conveyance of treated effluent were set up at the cost of Rs. 33.28 crores. The break-up of this cost is as under
    Internal Collection Systems Rs. 10.17 crore
    Treatment units Rs. 18.00 crore
    Conveyance line upto AMC Pirana Plant Sabarmati Rs. 05.11 crore
    Total Rs. 33.28 crore
    Expenditure towards additional equipment and
    installation / modification of new units.
    Rs. 11.74 crore
    Phase: I Up-gradation Rs. 06.70 crore
    Phase: II Up-gradation Rs. 06.70 crore
    Total Rs. 41.13 crore
    Grand Total Rs. 74.41 crore
    Thus the total Project Cost became Rs. 74.41 crore
  • Salient Features of the CETP:
    1. The CETP was designed to treat 16000 m3 of effluent / day making use of new technology known as AIS (Advent Integral System) which consists of Aeration Basin surrounded by Integrated Peripheral Secondary Clarifier. Later during the up-gradation programme this Integral Clarifier was converted into Aeration Zone and two separate Secondary Clarifiers were provided.
    2. The aeration is accomplished with the help of medium bubble aeration grid supplemented by 18 nos. of Triton type aerators supplied by Aeration Industries International Inc., Minneapolis, USA.
  • Charging Basis: The treatment charges are levied from the member units at the rate of Rs. 20 per kg of TOC in the effluent.
  • Inlet Norms: The CETP inlet norms applicable to the member units in respect of the quality of the effluent are as under…
  • BOD    1200 mg/l
    COD    3000 mg/l
    TSS     600 mg/l
  • The upper limits for the heavy metals and other pollutants have also been specified.
    The member units are required to adhere to the inlet norms. The quality of the effluent received at CETP is monitored and extra penal charges are levied from the member units violating these norms.
