South Goa water supply will face a partial disruption from October 31 to November 1 as the 100MLD Selaulim water treatment plant at Xelpem is shut for 24 hours, affecting Margao, Vasco, Mormugao and several surrounding areas, according to a report by The Times of India.
The plant shutdown is scheduled from 8am on October 31 to 8am on November 1. Water supply will be restricted in parts of Sanguem, Sanvordem, Quepem, Margao, Vasco and the Mormugao area during the maintenance-related operational stoppage.
The affected locations include Netravali, Zambaulim and Rivona in Sanguem; Guddemoll and Shiroda in Sanvordem; Quepem; Balli pumping station; Gudi; Margao; Fatorda; Raia; Fatepur; Handka; Loutolim; Cansaulim; Nagoa; Cuncolim; Curtorim; Nuvem; Cortalim; Dabolim; Vasco; and areas within the Mormugao constituency.
The disruption will not affect the entire Selaulim treatment system. The 160MLD Selaulim water treatment plant will remain fully operational during the shutdown period, according to the report. However, the stoppage of the 100MLD facility is expected to reduce available treatment capacity across the distribution network serving South Goa.
The impact is likely to be uneven across the affected areas because of the way water moves through a large, interconnected distribution system. Locations at the far ends of the network generally receive supply later after pumping and treatment operations resume. The report specifically identifies Cortalim, Dabolim, Vasco and Mormugao as tail-end areas where normalisation may take up to two days after the plant restarts.
For residents, institutions and businesses in these areas, the disruption could extend beyond the scheduled 24-hour shutdown window. The expected recovery period reflects the time required for supply pressures and distribution flows to stabilise across the network, particularly in areas that receive water later than locations closer to the treatment and pumping infrastructure.
The shutdown also highlights the dependence of South Goa’s urban settlements on a limited number of large treatment facilities. A planned stoppage at one plant can affect multiple municipalities, villages, industrial areas and transport-linked urban corridors at the same time, even when another treatment plant continues operating.
The operational schedule places the initial interruption on October 31 and the first expected restart on November 1. Normal water supply in the most distant parts of the network may take until approximately two days after operations resume, with Cortalim, Dabolim, Vasco and Mormugao specifically identified as areas requiring longer normalisation.
