Indian Prime Minister, Sri Narendra Modi inaugurated two sewerage treatment plants (STPs) at Beur & Karmalichak in Patna. Both these plants are powered by ABB’s 11KV/433V, 1250 KVA Compact Secondary Substations (CSS). ABB provided a fully internal arc tested Compact Substation to ensure safety of operator & equipment. CSS is a type tested solution comprising an enclosure containing medium voltage (MV) switchgear, distribution transformers, low voltage (LV) switchboards, connections and auxiliary equipment. The pre-fabricated and arc-tested nature of these solution make it very suitable for safety in public spaces with power equipment and also helps optimize the space footprint.
The STPs are part of the National Mission for Clean Ganga or the Namami Gange Program, an Integrated Conservation Mission aimed at accomplishing the twin objectives of effective abatement of pollution, conservation and rejuvenation of National River Ganga. Bihar Urban Infrastructure Development Corporation Limited, Patna (BUIDCO ) had awarded contact to Voltas limited as the EPC for STPs with whom ABB worked to provide the compact substations for efficient power distribution to this project. The ABB team has been involved in this project right from the inception stage and won this order.
Reliable power supply to enable seamless functioning of these STPs is critical as all the households will be connected through the sewerage pipeline network going further to these STPs to ensure that no untreated household waste water is directly released into the River Ganga. The local authorities have also ensured that the treated water would be utilized for power generation and irrigation by various enterprises.
