The quantity of water to be provided was further discussed in "Mazibuko v. City of Johannesburg". The case revolved around the distribution of water through pipes to Phiri, one of the oldest areas of Soweto. This case concerned two major issues: whether or not the city's policy regarding the supply of free basic water, 6 kilolitres per month to each account holder in the city was in conflict with Section 27 of the South African Constitution or Section 11 of the Water Services Act. The second issue being whether or not the installation of pre-paid water meters was lawful.
