The Democratic Alliance says the water crisis in Nelson Mandela Bay has now become a human rights issue.
Provincial leader and mayoral candidate Nqaba Bhanga, says he's written to the SA Human Rights Commission, calling for an investigation.
He says some areas of the Metro have been without running water for more than a week, and this has been erroneously being blamed on over-consumption.
Bhanga says the real issue is the inability of the Municipality to deal with the water crisis, accusing city leaders of allowing contracts for the supply of chemicals for water treatment works, among others, to expire.
He's also calling for an emergency meeting of the Municipal Public Accounts Committee to discuss various aspects of the water crisis.
Meanwhile, Nelson Mandela Bay Municipality says two water supply zones remain affected by disruptions.
MMC for Infrastructure, Mongameli Bobani, says the one is the Chelsea zone affecting areas that include Malabar, Westering, Linton Grange, Sherwood, Hunters Retreat and parts of Rowallan Park, Parsons Vlei, and Greenbushes.
He says the Chelsea reservoir is currently at 7% and water is being pumped in.
The second supply zone is Emeraldhill, affecting among others, Walmer Heights, parts of Lovemore Park, Mount Pleasant, Miramar and Charlo, Walmer Downs, Overbaakens, Fairview and parts of Newton Park.
Bobani says the Municipality is waiting for the water reticulation system to fill up.
He says the City will continue to experience intermittent water disruptions as we have reached day ZERO and the demand outweighs the supply.
There is also no significant rain predicted for the next three months and residents must continue to use only 50 litres per person per day.
In the meantime, water tankers have been dispatched to affected areas.
