Need for the CETP Compendium
In 2001, the Central Pollution Control Board (CPCB) published the “Guidelines for Management, Operation and Maintenance of Common Effluent Treatment Plants”. These provide guidance and support to CETP operators on how CETPs can be set up and managed, and on necessary requirements for the operations of a CETP and how a CETP can be successfully maintained and monitored.
In addition, GIZ together with the Confederation of Indian Industries (CII) Triveni Water Institute brought out the document “Common Effluent Treatment Plants: Overview, Technologies and Case Examples” in 2015. The document compiles information on problems faced by the sector, relevant environment-friendly technologies and results of case studies undertaken by GIZ. The document was targeted at policy makers, regulators and CETP operators and wanted to support them with improving the environmental performance of CETPs. Therefore, the document contains information on standards, legal framework and schemes relevant for CETPs, technological characteristics of CETPs as well as business and management models for CETPs. Beyond that, the document also contains case studies.
Although these two documents already contain a lot of relevant information on CETPs for different stakeholders, a new CETP Compendium is still seen as relevant. This is due to the fact that the documents still do not contain concisely all relevant information on CETPs.
Moreover, the documents are already outdated and new information on relevant technologies and business models is existing. At the same time, the European IPCC Bureau brought out a Best Available Techniques Reference Document (BREF) on “Common Waste Water and Waste Gas Treatment/Management Systems in the Chemical Sector” detailing various aspects in great detail (https://eippcb.jrc.ec.europa.eu/reference).
