It’s not enough: South Africa’s 25 litres of ‘basic water’ fails its constitutional test

South Africa’s 25 litres of ‘basic water’ starkly fails constitutional standards, compelling a reevaluation of what ‘sufficient’ truly means in the face of inequality.

Dr Anthony Kaziboni is a senior researcher at the Centre for Social Development in Africa (CSDA), University of Johannesburg.

World Health Organization standards suggest that South Africa’s definition of “basic water” is at a level closer to survival than sufficiency. The Constitution demands more.

The Constitution of the Republic of South Africa, Section 27(1)(b), guarantees that “everyone has the right to have access to sufficient food and water.” The keyword is not “access” – it is “sufficient”.

Crucially, the Constitution further requires the state to take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of this right.

This constitutional commitment does not disappear in legislation – but it is subtly reframed. The 1997 Water Services Act (Section 3(1)) affirms that “everyone has a right of access to basic water supply and basic sanitation.” Similarly, the National Water Act (1998) prioritises water resources of sufficient quantity and quality to meet basic human needs.

The shift is easy to miss, but significant. What begins in the Constitution as a right to sufficient water is translated in policy and legislation into a standard of basic provision.

Because in practice, South Africa operationalises this right through a minimum standard of 25 litres per person per day (or six kilolitres per household per month), delivered at a prescribed flow rate, within 200 metres of a household, and with limited interruption of supply.

This number has become normalised. It is often presented as reasonable – sometimes even progressive.

But globally, it sits at the lower edge of what is considered bare survival, not adequacy. At around 20-25 litres per person per day, water access is classified as “basic” – a level at which drinking and cooking may be met, but hygiene is only partially assured, and activities such as bathing and laundry are compromised. Health risks remain high:Source: Domestic water quantity, service level and health

It is only at roughly 50 litres per person per day that water access reaches an “intermediate” level – where daily domestic needs, including hygiene, can be met with some reliability.

In other words, what South Africa defines as “sufficient” aligns more closely with what global standards recognise as inadequate for a healthy and dignified life:
