Farm Water Rights in South Africa

On an irrigation farm in South Africa, the water right is often more valuable than the land itself. This guide explains what water rights actually are under the National Water Act 36 of 1998, the four categories of authorisation a farm can hold, how to verify those rights before buying, and how they transfer with the property at the Deeds Office.

▣ Key Facts at a Glance

  • All water in South Africa is a national resource held in public trust under the National Water Act 36 of 1998. Private water ownership does not exist; what farmers hold are formal water use authorisations.
  • The Department of Water and Sanitation (DWS) administers water use, with Catchment Management Agencies and Water User Associations operating at regional level.
  • There are four practical categories of water use authorisation: Schedule 1 (minor use, no licence), Existing Lawful Use (pre-1998), General Authorisations, and Water Use Licences issued under Section 21.
  • On an irrigation farm, the registered water allocation is often more valuable than the land itself. Verify the volume, source, and authorisation type before signing an Offer to Purchase.
  • Water use authorisations tied to land normally transfer with the land, but DWS endorsement may be required and should be confirmed by the conveyancer in writing.
  • A water right that has not been used for an extended period can be reduced or cancelled. Continuity of use is part of the right, especially for Existing Lawful Use.

What Are Water Rights in South Africa?

The National Water Act 36 of 1998 fundamentally changed how water is held in South Africa. Before 1998, water rights were largely tied to the land itself, through riparian and other historic doctrines. From 1 October 1998, all water in the country became a national resource held in public trust, administered by the Department of Water and Sanitation (DWS) on behalf of all South Africans.

That sounds drastic, and in legal theory it was. In practical farming terms, the existing uses of water were preserved through the Existing Lawful Use mechanism, and the new framework provides Water Use Licences for new uses. The right to take water from a river, a borehole or a dam still exists. It is now expressed as a formal authorisation rather than as an automatic feature of land ownership.

For a farm buyer, this means three things. First, the water right is a separately verifiable asset attached to the property, not an automatic consequence of buying the land. Second, the form of the right (Schedule 1 minor use, Existing Lawful Use, General Authorisation, or Water Use Licence) determines its strength and transferability. Third, water rights can be lost through non-use, breach of conditions, or compulsory licensing in stressed catchments. Buying an irrigation farm without verifying these things is not buying an irrigation farm. It is buying a hopeful smallholding.

The Four Categories of Water Authorisation

Schedule 1: Minor Reasonable Use

No licence required. Covers small-scale domestic use, watering of a few livestock, a household garden, and emergency firefighting. Not relevant to commercial farming volumes, but useful for understanding the bottom rung of the framework.

Existing Lawful Use (ELU)

Water uses that were lawful in the two years before 1 October 1998 and that have continued on a substantially similar basis. Most older irrigation farms in the Free State and Northern Cape rely on ELU. It is registered with DWS but does not require a Water Use Licence to continue. It is conditional on continuity of use, and can be reduced through Compulsory Licensing in stressed catchments.

General Authorisations

DWS publishes General Authorisations in the Government Gazette permitting specified categories of water use in specified areas, up to specified volumes, without an individual Water Use Licence. Coverage and conditions vary by Water Management Area. Confirm whether a General Authorisation applies to the source on the farm and what conditions it imposes.

Water Use Licence (WUL)

A formal authorisation issued by DWS under Section 21 of the National Water Act, for one or more of the eleven listed categories of water use. A current Water Use Licence is the strongest form of authorisation a farm can hold. The licence states the source, the allocation, the area irrigated, monitoring requirements, and any conditions of use. Most new commercial agricultural water use requires a WUL.

Eight-Step Verification Process Before You Buy

  1. 1. Identify every water source on the property

    Walk the property and list every water source. Surface sources include rivers, streams, canals, weirs, dams and storage facilities. Groundwater sources include boreholes, wellpoints and springs. Note their location, the equipment in place (pumps, pipelines, storage tanks, centre-pivot infrastructure), the area each source irrigates, and any sources shared with neighbours. A farm relying on more than one source is the norm, not the exception.

  2. 2. Confirm registration with the Department of Water and Sanitation

    Every commercial water use on a South African farm should be registered with the Department of Water and Sanitation (DWS). Request the seller's most recent DWS registration documents, the Water Use Authorisation (or Existing Lawful Use entry), and any allocation correspondence. If registration cannot be produced, treat the source as unconfirmed until DWS has verified it directly. Unregistered use is not the same as no right, but it carries risk.

  3. 3. Verify the allocation volume

    Water entitlements are quantified in volumes per year (typically cubic metres per year, sometimes megalitres). Confirm the allocation in writing and compare it against the area currently under irrigation. As a working rule for South African farming, a centre-pivot of 30 to 40 hectares requires a meaningful allocation; a smallholding garden does not. Mismatches between the registered allocation and the actual irrigated area are a serious due-diligence red flag.

  4. 4. Confirm the type of authorisation

    South African water use falls into four practical categories under the National Water Act 36 of 1998: Schedule 1 (minor reasonable use, no licence required), Existing Lawful Use (lawful pre-1 October 1998 uses that continue today), General Authorisations (DWS-published authorisations for specified bulk use), and Water Use Licences issued under Section 21. Knowing which category applies to each source on the farm is essential. A registered Water Use Licence is the strongest position; an unverified historical claim of Existing Lawful Use is the weakest.

  5. 5. Check transferability with the property

    In principle, a water use authorisation tied to the land transfers with the land. In practice, DWS endorsement may be required, particularly for Section 21 licences. Ask the conveyancer to verify whether the Water Use Licence needs to be formally endorsed for the new owner, and whether any conditions of the licence (such as metering, reporting, or beneficial use) survive the transfer. Some authorisations lapse if not exercised; confirm continuity.

  6. 6. Check historical use compliance

    A water right that has not been used for an extended period can be reduced or cancelled by DWS. For Existing Lawful Use in particular, the use must be ongoing and substantially similar to the pre-1998 use. Ask for irrigation records, electricity accounts for pumps, fuel records, and crop or pasture records covering the last few years. A farm marketed as fully irrigated but with no recent power or fuel consumption deserves close inspection.

  7. 7. Verify Water User Association membership and infrastructure ownership

    In many irrigation regions, particularly the Orange River, Vaal River and Crocodile River systems, farms belong to a Water User Association (WUA) or successor body. Confirm WUA membership, levy status, and the boundaries of communal infrastructure (canals, off-takes, headworks). Establish what infrastructure belongs to the farm and what belongs to the WUA. Outstanding levies can become the buyer's responsibility if not settled at transfer.

  8. 8. Reflect the water rights in the Offer to Purchase

    The Offer to Purchase must record the water rights explicitly. List the source, the authorisation type, the allocation volume, the WUA (if any) and any infrastructure being transferred. Make the offer subject to a satisfactory due-diligence outcome and, where relevant, DWS endorsement of the Water Use Licence in the buyer's name. A specialist agricultural conveyancer should draft the relevant clauses; a borrowed residential template will not protect you.

Common Pitfalls We See

  • Taking the seller's word for the allocation. The volume the seller mentions in conversation and the volume on the DWS authorisation are not always the same. Insist on the registration documents in writing before signing.
  • Assuming an Existing Lawful Use is fully secure. ELU depends on continuity of use. A farm that has been dormant or under-utilised for several years may have a weaker ELU position than the seller realises.
  • Buying a farm where the irrigated area exceeds the registered allocation. This is a common red flag, particularly on older irrigation properties where the area under pivot has been expanded over time without updating the authorisation.
  • Missing the Water User Association levy position. Outstanding WUA levies survive transfer in the same way as rates and taxes. Settle the position with the WUA before registration.
  • Using a residential conveyancing template. Standard Offers to Purchase do not handle water rights properly. The conveyancer must draft specific clauses covering source, allocation, authorisation type, transferability, and DWS endorsement.
  • Forgetting that water rights can be lost. Compulsory Licensing under Section 43 of the National Water Act allows DWS to reduce allocations in stressed Water Management Areas. Buy with this risk in mind, particularly in areas under hydrological pressure.

Frequently Asked Questions

What are water rights in South Africa?

Under the National Water Act 36 of 1998, all water in South Africa is a national resource held in public trust. Private "ownership" of water as such does not exist. What farmers and landowners hold are formal water use authorisations: the right to take a specified volume of surface or groundwater from a defined source, under conditions set by the Department of Water and Sanitation (DWS). These authorisations fall into four categories: Schedule 1 minor use, Existing Lawful Use, General Authorisations, and Water Use Licences.

Do water rights transfer with the farm when it is sold?

In principle, yes. A water use authorisation that is tied to the land normally transfers with the land at registration. In practice, the Department of Water and Sanitation may require formal endorsement of a Water Use Licence in the new owner's name, and some authorisations carry conditions that need to be re-confirmed. Always ask the conveyancer to verify in writing that the water use authorisation will survive transfer in the form represented, and reflect the position in the Offer to Purchase.

What is Existing Lawful Use?

Existing Lawful Use (ELU) covers water uses that were lawful in the two years before 1 October 1998 (when the National Water Act took effect) and that continue today on a substantially similar basis. ELU does not require a licence to continue, but it must be registered with DWS and the historical use pattern must be verifiable. Many farms in the older irrigation regions rely on ELU rather than Section 21 licences. ELU can be reduced or formalised by DWS through a process called Compulsory Licensing where a Water Management Area is under stress.

What is a Water Use Licence?

A Water Use Licence (WUL) is a formal authorisation issued by DWS under Section 21 of the National Water Act for specified categories of water use, including taking water from a watercourse, storing water, and various other categories. Most new commercial agricultural water use requires a WUL. The licence sets the allocation volume, source, area irrigated, monitoring requirements and other conditions. A registered, current WUL is the most defensible form of water authorisation a farm can have.

How do I verify water rights before buying a farm?

Ask the seller for the most recent DWS registration documents and Water Use Authorisation in writing. Confirm the volume allocated, the source, the type of authorisation, and the historical use. Compare the registered allocation against the area actually under irrigation. Check Water User Association membership and levies. Ask the conveyancer to verify whether endorsement is required at transfer. Where the source is critical to the value of the farm, commission an independent confirmation from DWS or a specialist water rights consultant before signing.

How are water rights priced or charged in South Africa?

DWS levies water use charges based on the registered allocation and the source. The Pricing Strategy under the National Water Act sets out charges for waterworks, catchment management, and the economic cost of water. Water User Associations charge their own levies for shared infrastructure. The total annual cost of water on an irrigation farm can be material and should be confirmed during due diligence. Outstanding levies attach to the property until settled.

Can a water right be lost or cancelled?

Yes. Long non-use of a water use authorisation, breach of licence conditions, or a Compulsory Licensing process initiated by DWS in a stressed Water Management Area can all result in a water entitlement being reduced or cancelled. For Existing Lawful Use, prolonged non-use is a particular risk because the right depends on continuity. A farm that has been dormant for several years should be inspected carefully before any reliance is placed on its historical water rights.

What is Section 21 of the National Water Act?

Section 21 of the National Water Act 36 of 1998 lists the eleven categories of water use that require authorisation, including taking water from a water resource, storing water, impeding or diverting flow, engaging in a stream flow reduction activity, irrigating with waste, and altering a watercourse. Almost all commercial agricultural water use falls under one or more Section 21 categories. The category determines whether the use is permitted under Schedule 1, a General Authorisation, an Existing Lawful Use entry, or a Water Use Licence.
