Recent events involving a municipality highlight a recurring problem for contractors appointed to build, operate or maintain essential municipal infrastructure: what happens when the municipality stops paying but expects work to continue?
In July 2026, media reports reported on protests by water and sanitation contractors in KwaZulu-Natal, some allegedly owed hundreds of thousands of rands, protesting at a municipal water services depot. Their work reportedly included servicing sewer systems and repairing burst pipes.
The strain is immediate: contractors must pay employees, subcontractors and suppliers, buy materials and fund performance. The effect is that when payments stop, contractors may be forced to finance an essential public service themselves.
The central question is whether the contractor must keep working or may suspend performance until payment is made.
The implications
No general rule requires a municipal contractor to work indefinitely without payment. Simply “downing tools” and abandoning site, however, is extremely risky.
The right to suspend or cancel a contract depends principally on the terms of the contract, including its payment dates, default provisions, notice requirements and available remedies.
A contractor that suspends prematurely, gives defective notice or ignores the agreed procedure may itself breach or repudiate the contract, risk cancellation, claims for damages, a call on security and other consequences.
For essential infrastructure, suspension may also trigger immediate pressure from the municipality, affected communities and, in some cases, the courts.
The public importance of the work does not, however, automatically remove the contractor’s contractual remedies.
The legal position
The starting point is to separate the contractor’s commercial obligations from the municipality’s public-law duties to the community.
The Constitution recognises the right of access to sufficient water. The Water Services Act 108 of 1997 requires a water services authority (including a municipality, district or rural council as defined in the Local Government Transition Act 209 of 1993) to progressively ensure efficient, affordable, economical and sustainable access to water services. The Water Services Act nevertheless allows water services authorities to appoint service providers.
Similarly, where section 81 of the Local Government: Municipal Systems Act 32 of 2000 applies to a service delivered by an external provider, the municipality remains responsible for uninterrupted delivery.
Appointing a contractor does not necessarily transfer the municipality’s underlying public-law duties; those duties and any payment disputes rest on different legal bases.
The decision in Ndlambe Local Municipality v Quality Filtration Systems (Pty) Ltd and Another illustrates the distinction.
The contractor worked on Port Alfred’s emergency reverse-osmosis water system. After the municipality failed to pay certified amounts, the contractor invoked the FIDIC suspension provisions and stopped work. The municipality asked the High Court to compel performance, relying partly on the community’s need for water.
The Court held that the municipality had breached its payment obligations and the contractor had met the contractual notice requirements. The contractor could therefore suspend despite the importance of water delivery and the municipality’s constitutional duties.
The case does not create an automatic right to suspend work whenever payment is late. It shows that, if the contract permits suspension and the contractor follows the procedure correctly and in accordance with the terms of the contract, the service’s essential nature does not necessarily require continued performance without payment.
The common law is also indicative. Where contractual obligations are reciprocal, a party may in some circumstances withhold performance until the other party renders the counter-performance due. Whether the principle applies depends on the contract and the relationship between the obligations of the parties.
For a contractor faced with non-payment by a municipality, how the contractor suspends is as important as whether it may do so.
Before suspending work, the contractor should establish that the amount relied upon has in fact become due and payable, identify the precise contractual provision entitling it to suspend, and comply strictly with any notice and waiting periods. Particular care should be taken where the contract contains its own dispute-resolution process or imposes additional requirements before suspension or cancellation of contract.
The contractor’s correspondence must identify the outstanding payment, the breach and suspension provision, the steps required to remedy the breach, and the date suspension will take effect if it is not remedied.
The Ndlambe case illustrates why this matters. The contractor succeeded because the municipality had not paid and the contractual requirements for suspension had been met.
Contractors should not stop work out of frustration. A proper contractually implemented suspension is not an abandonment of the works.
Municipal contractors need not finance public infrastructure indefinitely (or at all) merely because their services matter to the community. Suspension is a powerful remedy but with serious consequences if exercised incorrectly.
Contractors should act before non-payment becomes untenable: establish their rights, preserve evidence, issue the required notices and suspend only in accordance with the terms of the contract.
Once a contractor has already stopped work without following the contractual procedure, its position can become considerably more difficult to retrospectively recover. The perception of abandonment of the works and repudiation of contract by the contractor must be avoided at all costs.
If the contract provides remedies, then those remedies must be exercised by the contractor. Any action or inaction by the contractor which amounts to repudiation and/or breach of contract can lead to severe consequences such as cancellation of the contract coupled with concomitant claims for damages.
Early advice can distinguish a lawful suspension that protects the contractor from one that invites allegations of breach, cancellation of contract or a call on security.
