Hydrology

The city has a long marine coastline on its outskirts, particularly southwards. Beaches like Kings Beach, Hobie Beach, Bluewater Bay, Sardinia Bay (just outside the city near Schoenmakerskop), and the beaches along Marine Drive are abundant. Kings Beach is adjacent to the harbour, and the longshore drift from Cape Recife provides a plentiful supply of sea sand. On the north westerly coastline, the contours tends to be rockier than the area between Cape Recife, and the Port of Ngqura. There are a few rivers, of which the Baakens River is the most prominent. This river usually floods when a reasonable amount precipitation is observed, especially at low level crossings. North End Lake in North End is the largest natural freshwater body in the city, but has experienced a form of contamination from industry. (It is not recommended to ingest anything from this lake) Also, numerous smaller "lakes" are in the surrounding area, namely Lake Farm.

The Eastern Cape has been experiencing a devastating drought since 2015, and a disaster was declared in the region in October 2019. On 14 June 2022, a virtual special council meeting of Nelson Mandela Bay Municipality Council approved an emergency intervention plan by the National Department of Water and Sanitation. The plan includes: drilling more boreholes, pumping water from the east of the metropolitan area to the west of the area, and using floatation pumps to extract more water from some reservoirs. The meeting approved the appointment of Tlhologelo Mogoatlhe (a water and sanitation production engineer) as the interim infrastructure and engineering executive director. City officials asked residents to consume no more than 50 litres (11 imp gal) of water per person per day. In mid-June 2022, Luvuyo Bangazi (spokesperson for the municipality's joint operations crisis committee) said that the city was losing about a third of its water because of leaks in pipes, and had a backlog of 3,000 leaks to fix. Joseph Tsatsire (Bay Water Distribution Director) said that Nelson Mandela Bay Municipality repaired 9,719 leaks over a three week period ending in mid-July 2022, leaving a backlog of 712 leaks reported. Though some residents claimed that the taps only work a few hours a day, Bangazi said that water was only shut off when maintenance was being done. Water consumption for the Nelson Mandela Bay Municipality was as follows:
