Nellore — a major coastal agricultural and aquaculture city on the Penna (Pennar) River — faces acute drainage challenges from its flat coastal terrain, cyclone exposure, and expanding urban area. The Penna River delta canals and NMC's stormwater drain network collect heavy silt loads during the NE Monsoon and cyclone season (October–December), causing widespread waterlogging.
VARMAN operates across all NMC wards — including rapidly growing zones like Muthukur Road, Balaji Nagar, and Vedayapalem — using mechanical excavators, suction tankers, and jetting trucks suited to Nellore's flat, high-silt coastal drainage environment.
