Located between the Powai and V ihar lakes of East Mumbai, IIT Bombay has a
sprawling campus of about 550 acres. The green cover of the campus has been
maintained over the years and gives the campus an idyllic appearance. The institution
authorities have, in fact, been very keen on embodying and exemplifying a sustainable
spirit towards education and research. Sewage disposal of this massive campus, with
nearly 600 major buildings, had to be in line with the same spirit.
MCC Control Panel installed at IIT Powai
Challenge
The organisation was looking at a sewage disposal solution which combined the
benefits of automatic operation as well as energy ef ficiency . The most important

consideration was to reduce human intervention. The control panel had to be designed
so as to avoid energy wastage and ensure the highest ef ficiency . Finally , an emergency
alarm mechanism had to be installed for sudden spurts in sewage.
Our Solution
After a thorough feasibility study of the existing disposal system at the campus, we
designed a
motor control center
(MCC) panel, considering
the requirements of control,
safety and ef ficiency . Detailed Single Line Diagrams and General Arrangement
Drawings were discussed with the client. Components of the highest quality were used
and a state-of-the-art graphical display was installed for tracking parameters such as
voltage, current and frequency .
Working of the MCC panel
The working logic formed the core of our sewage disposal solution. The sewage tank
was calibrated with markers of 20%, 40%, 60%, and 80%, and all pumps were to be
OFF with sewage levels below the 20% (Low) mark. As soon as the sewage fluid would
rise above the 40% (High) mark, Pump #1 would start and stop only when the fluid
levels dropped below the 20% mark. In case the fluid levels rose above the 60% mark
(Very High), Pump #2 would start and run alongside Pump #1. If the fluid levels crossed
the 80% (V ery V ery High) mark, Pump #3 would start and run alongside pumps #1 and
#2. An alarm would also go of f as soon as the fluid level crossed the 80% mark. As the
level of sewage fluid dropped through the markers, the pumps would stop running, one
at a time, in the first in first out (FIFO) mode. Finally , with the sewage fluid dropping
below the 20% (Low) mark, all pumps would stop and the cycle of running the pumps
would change to ensure equal usage of all pump sets.
The Impact
This working logic ensured the proportionate usage of pumps in response to the volume
of sewage in the tank and also used all the pump sets equally , to avoid wear and tear of
only one or a few pumps.
