The comprehensive surge analysis of water transmission mains for the Laxmangarh-Fatehpur area in India was carried out by simulating
various triggering conditions and proposing surge protection equipment. The ultimate goal of this INR 1.52 billion project was to design and
execute a system that could deliver 90. 44 million liters per day (MLD), 73. 67 MLD, and 43.06 MLD of treated water to various sectors.
L&T Construction used WaterGEMS and HAMMER for the analyses. HAMMER enabled various surge protection systems to be analyzed
and compared based on their effectiveness and risk reduction to the hydraulic transmission model. In the end, a combination of double-acting kinetic air valves was proposed as the most cost-effective solution, because it was able to keep the pressure values well within
limits as required by India’s regulatory board.
This INR 1.21 billion project consisted of a new sewer network that integrated with existing infrastructure by rehabilitating old sewers
throughout the Kalyani area of Kolkata, India. Pumping stations were proposed that would collect and pump the sewage to the existing
facilities, while treatment of the influent was augmented once at its destination. Different scenarios were simulated and ultimately reduced
the project cost and enhanced productivity.
L&T Construction imported AutoCAD survey drawings into SewerGEMS, and the information was synchronized for analyzing and optimizing
the network design. Extreme/peak flow patterns in SewerGEMS helped in restricting maximum depth of sewer, thereby rezoning the
system. The scenario option in SewerGEMS helped the team calculate a number of what-if analyses with the network, which would have
been tedious to carry out manually.
