The Nelson Mandela Bay Municipality has called on residents to save water as a transformer malfunction could affect supply.
Municipality spokesperson, Kupido Baron, says large parts of the Metro could experience the disruption in their water supply by lunch time today.
He says an electrical transformer at the Loerie Water Treatment Works malfunctioned last night, affecting the pumping of water to some of the reservoirs.
Baron says while repairs to the transformer are under way, its unlikely that power will be restored before 2pm.
The affected areas are Westering, Framesby, Sunridge Park, Kabega Park, Cotswold, Linton Grange, Lorraine, Ben Kamma, Kamma Park, Weybridge Park, Kragga Kamma, Sherwood, Kunene Park, Rowallan Park, Shauderville and Malabar.
Residents from these areas are requested to urgently cut the non-essential use of water.
