Expanding Operational Excellence Beyond Commissioning
Completed infrastructure becomes a lasting public asset only when supported by robust Operation & Maintenance (O&M). MEIL Group now sustains major lift irrigation schemes, drinking water systems, urban water grids, sewage treatment plants, and hydropower assets across India, with teams monitoring pump houses, pipelines, reservoirs, and electrical systems round the clock to minimise interruptions, optimise efficiency, and deliver reliable services to millions. These O&M efforts cover flagship projects such as Handri Neeva Sujala Sravanthi (HNSS), Kaleshwaram Lift Irrigation Scheme (KLIS), Mission Bhagiratha segments, and numerous regional schemes in Telangana, Andhra Pradesh, Karnataka, Gujarat, Rajasthan, Odisha, and Bihar.
HNSS is one of the biggest lift irrigation projects and a unique scheme globally for the scale and number of pumping units in operation. MEIL Group executed 43 pump houses with a total of 289 machines, which have been running successfully for nearly a decade, with MEIL’s O&M teams keeping them in continuous service.
Kaleshwaram Lift Irrigation Scheme in Telangana is the world’s largest multi stage lift irrigation project, designed to lift around 3 TMC of Godavari water per day through a cascade of pump houses. MEIL Group executed the core electromechanical and pumping infrastructure by constructing 15 of the scheme’s 22 pumping stations, installing 89 pumping machines with a combined capacity of about 3,840 MW, and commissioning large underground and surface pump houses such as Medigadda (Lakshmi), Annaram (Saraswati), Sundilla (Parvathi), Ranganayaka Sagar, Mallanna Sagar, and Kondapochamma Sagar.
A key engineering milestone in KLIS is the Gayatri underground pump house at Lakshmipur, built at a depth of about 470 feet, around 180 metres below ground, housing seven high capacity pumps of 139 MW each, with a total installed capacity of about 973 MW. This pump house can lift 3 TMC of water per day and is supported by dedicated 400 kV and 220 kV power infrastructure that MEIL helped develop as part of the scheme. Through long term O&M, MEIL’s teams keep these large machines, switchyards, and associated systems operating reliably to meet irrigation and drinking water commitments across Telangana.
Beyond lift irrigation, MEIL Group’s O&M footprint spans multiple drinking water and urban services schemes. In Karnataka, drinking water projects in locations such as Arsikere, Hanur and Pavagada and farm oriented schemes in Kolar and Koppal are operated with maintained pump houses, treatment units, and reservoirs to ensure a stable supply to towns and rural habitations. In Hyderabad, MEIL has constructed several major sewage treatment plants (STPs) for Hyderabad Metropolitan Water Supply & Sewerage Board (HMWSSB), including facilities such as the 865 MLD Nallacheruvu STP, and contributes to the city’s move towards full sewage treatment and non-potable reuse.
MEIL Group also supports long term operation of key water supply and irrigation schemes in Rajasthan, Chambal–Bhilwara, Kotri Tehsil, Asind Tehsil, Jetpur–Pali, and Shahpura Tehsil projects, in Odisha, Bhubaneswar bulk water supply, focusing on steady output and minimal breakdowns. Other O&M engagements include Pulikanuma LIS, Patiseema LIS, Godavari Water Supply Scheme, Purushothapatnam LIS, Kondaveeti Vagu LIS, Proddatur Water Supply Scheme, Uddanam Drinking Water Project, Nellore WSS, Dhone WSP, Kaddem LIS, Gajwel Water Grid, Sauni Yojana, KBC Lift Scheme, Ganga Jal Aapurti Yojana, and the NMDC Raw Water Supply Scheme.
In the hydropower segment, the 25 MW Lambadug Hydroelectric Power Project in Himachal Pradesh continues to generate clean power from a deep valley Himalayan site, supported by regular maintenance of its intakes, penstocks, turbines, and control systems. The Saurashtra Branch Canal Small Hydro Power Project in Gujarat harnesses canal flows through multiple powerhouses along the Saurashtra Branch Canal, where sustained O&M keeps canal intakes, turbines, and generators operating at high availability.
From Andhra Pradesh fields to Telangana farmlands, Karnataka villages to Gujarat rivers, Rajasthan deserts to Bihar plains, our teams maintain and build water projects across India’s length and breadth. Be it any project or sector, we deliver pan- India contributions through asset creation, community resources, employment generation and indirect tax revenues, creating a cascading economic effect that uplifts the nation.
