Senior Japanese officials visited the the Okhla Sewage Treatment (STP) plant on Monday.
Dr. Akihiko Tanaka, president of Japan International Cooperation Agency (JICA) -- an agency of the Japanese government -- and took stock of the cleaning process at the plant. The JICA is responsible for implementing the Japanese Official Development Assistance (ODA) to developing countries.
The Okhla plant (STP) is a 30MGD STP based on an activated sludge process. A very unique feature of the plant is that the plant disinfects the final treated water before it is disposed of in the Yamuna, which helps in reducing the bacterial load.
Gas generated in the process of waste water treatment is used to generate power, making the plant self-sufficient to the extent of about 60 per cent of its power requirement.
The president of JICA was accompanied by Naka Hara, director general of JICA and Debashree Mukherjee, CEO of Delhi Jal Board(DJB). Other senior officials of DJB were present during the visit.
The Yamuna Action Plan III aims at a comprehensive development of three selected sewerage zones (Okhla, Kondli and Rithala) in Delhi for modernization and complete coverage for basic sanitation facilities in urban and non-urban areas of Delhi.
It will broadly cover renovation and repair of aged assets, upgradation of treatment standards, new proposals to manage the increased dry weather flows and optimum utilization of existing sewage conveying facilities.
The JICA has been actively supporting the Yamuna Action Plan I and II and they are continuing with their cooperation and support along with DJB for the Yamuna Action Plan III as well.
