How long should a borehole workmanship warranty last?

One to two years is a typical minimum for drilling and casing workmanship, though some contractors offer longer. The pump manufacturer's warranty is separate and typically also runs one to two years from installation. Always confirm both periods in writing before signing a contract.

Can I get a guarantee that my borehole will produce enough water?

Outright yield guarantees are uncommon and heavily conditioned because geology is not fully predictable before drilling. What you can reasonably negotiate is a commitment to a post-drilling pump test, documented results, and a defined remedial process if yield falls below an agreed minimum within a set period. Any yield guarantee should specify the exact trigger conditions and the remedy — not just a vague promise.

What happens if my pump fails outside the warranty period?

Outside warranty, pump replacement or repair is at your own cost. Borehole pumps typically cost R15,000 to R35,000 installed, so budgeting for eventual replacement is sensible. Keeping records of your original pump test results helps a technician diagnose whether a failure is due to a changing aquifer or a pump issue.

Who do I complain to if a contractor refuses to honour a warranty?

Your first step is a written complaint to the contractor referencing the specific warranty clause and the Consumer Protection Act. If that fails, the Construction GQSS Ombudsman (CGSO) handles disputes for registered member contractors, and the National Consumer Commission (NCC) is the broader statutory body for CPA complaints. Keep all documentation — contracts, invoices, pump test records, and correspondence.

Is borehole water automatically safe to drink if the installation is done correctly?

No. Installation quality affects structural integrity and contamination risk from surface ingress, but groundwater chemistry varies by location and can change over time regardless of installation quality. Have the water tested against SANS 241 (2024 edition) before using it for any domestic purpose, and retest periodically. Treatment decisions should follow test results, not assumptions.

Borehole Warranties: What Should Be Covered

Getting a borehole drilled is a significant outlay — typically R60,000 to R100,000 for a complete system in Johannesburg, with the full range running R40,000 to R150,000 depending on depth, geology and equipment. A warranty is one of the few protections you have if something goes wrong after the crew leaves your property. Yet borehole warranties vary enormously between contractors, and many homeowners only read the fine print after a problem has already surfaced. This guide explains what a properly structured borehole warranty should cover, what exclusions to watch for, and how to avoid being left exposed.

Why Borehole Warranties Are Not Standardised

Unlike household appliances, borehole installations are not governed by a single mandatory warranty framework specific to the drilling industry. The Consumer Protection Act (CPA) provides a general implied warranty of quality on goods and services supplied in the ordinary course of business, and the National Consumer Commission oversees its enforcement. The Construction GQSS Ombudsman (CGSO) offers a dispute resolution channel for construction-related complaints where a contractor is a registered member. However, neither body prescribes the exact scope of a borehole-specific warranty.

This means you are largely relying on what your contractor puts in writing — and that varies widely. Some contractors provide detailed multi-page warranty documents; others include a single sentence in a quotation. Neither the CPA nor CGSO membership automatically fills in gaps a contractor has left out of the contract, so the burden is on you to ask the right questions before signing.

What a Borehole Warranty Should Cover

1. Drilling and Casing Workmanship

The borehole itself — the hole, the casing, and the grout seal — should carry a workmanship warranty. A reasonable period is typically one to two years, though longer is better and some reputable contractors offer more. This warranty should cover:

Structural integrity of the casing — the casing should not collapse, deform or allow surface water ingress under normal conditions.
Plumbness and straightness — a borehole that is drilled off-plumb can cause pump wear and eventually pump failure. If deviation was within contractor control, any resulting damage should be a warranty matter.
Grout seal quality — the annular seal prevents contaminated surface water from tracking down into the aquifer. Failure here is both a yield and a water-quality risk.

2. Pump and Pump Installation

The pump is the most mechanically vulnerable component of your system and also where most post-installation failures occur. There are two distinct warranty elements here:

Manufacturer’s warranty on the pump itself — most reputable pump brands carry a one- to two-year manufacturer’s warranty. Confirm your installer is fitting a branded pump with a traceable serial number, and that the warranty is registered in your name.
Installation workmanship — even a good pump fails prematurely if it is set at the wrong depth, incorrectly wired, or poorly secured. The installer should warrant their own workmanship on the installation separately from the manufacturer’s product warranty.

Borehole pumps typically cost R15,000 to R35,000 installed, so a pump failure outside warranty is a painful unplanned expense. For more detail on how pump specifications interact with the rest of your system, the borehole drilling guide covers the main components and what to ask about.

3. Yield — The Complicated One

Yield guarantees are the most contentious area of borehole warranties. Geology is not perfectly predictable, and most contractors are reluctant to guarantee a specific yield in litres per hour. That is not unreasonable — aquifer behaviour varies.

What you can reasonably ask for is:

A commitment to conduct a proper pump test after drilling and to provide you with the documented results.
A clause that if yield falls below a stated minimum within a defined period (say, six months), the contractor will attempt a remedial intervention (deepening, airlift development, or similar) at no additional cost.
Clarity on what happens if the borehole is genuinely dry or fails to sustain the agreed minimum yield — is there any partial refund mechanism?

Most contractors will not offer a full money-back yield guarantee, and be cautious of any who do without conditions — understand exactly what triggers it and what the remedy actually is.

Exclusions That Leave You Exposed

Standard borehole warranty exclusions are where most disputes originate. Look out for the following:

Exclusion	Why It Matters
Natural geological variation	Can be used to deny liability for low yield even when the site was not properly assessed
Power quality or surge damage	Joburg’s grid instability is a real risk; ask who is responsible if a surge kills the pump
Lack of water treatment equipment	Warranty may be voided if water quality damages the pump — but the contractor chose the pump
Failure to use contractor’s own service team	Ties you to one service provider indefinitely
No borehole log or pump test record provided	Without records, it is nearly impossible to establish a baseline for warranty claims

Always ask the contractor to walk you through every exclusion verbally, and get any clarifications added to the written contract.

What Documentation You Should Receive

A warranty is only as useful as your ability to enforce it. To support any future claim, insist on receiving the following in writing at project completion:

Borehole log — the driller’s record of depth, geology encountered, and casing details.
Pump test results — including static water level, pumping water level, and sustainable yield in litres per hour.
Pump serial number and manufacturer’s warranty card — registered in your name.
As-installed diagram — showing pump set depth, pipe sizes, and surface connections.
Signed completion certificate — confirming the installation matches the scope of work in the contract.

Without these documents you have very little to stand on if a dispute goes to the CGSO or the NCC. Keep digital and physical copies.

Water Quality and SANS 241

One area warranties almost never cover is ongoing water quality — and that is actually reasonable, because water quality can change over time for reasons entirely unrelated to the installation. What the contractor should warrant is that the borehole construction does not itself introduce contamination (poor grout sealing being the main risk).

Before you use borehole water for any domestic purpose, have it tested against SANS 241 (2024 edition), the South African drinking-water quality standard. This is not the contractor’s responsibility to arrange on your behalf — it is yours. Test first, treat second. No warranty clause substitutes for knowing what is actually in your water.

Choosing a Contractor With a Warranty Worth Having

The quality of a warranty document tells you a great deal about a contractor. A contractor who provides a clear, detailed warranty — covering workmanship, pump installation, and documented exclusions — is demonstrating professional accountability. One who offers a vague verbal assurance or a single-sentence clause is a risk.

Before you appoint anyone, read what to look for in a borehole drilling company for a full checklist of contractor selection criteria. Once you have shortlisted candidates, understanding how installer warranties work in practice will help you interrogate what each contractor is actually committing to — and what they are not.

If you are still comparing contractors, getting multiple written quotes makes it far easier to benchmark warranty terms side by side. Request quotes from vetted local installers — free and without obligation.

Before You Sign

A borehole is a long-term asset — a well-drilled borehole with a properly maintained pump can serve a property for decades. The warranty period is a fraction of that lifespan, but it covers the highest-risk phase when installation defects are most likely to surface. Read the warranty document carefully, ask about every exclusion, insist on all supporting documentation, and do not accept verbal assurances as a substitute for written terms. If a contractor is reluctant to put something in writing, that reluctance is itself useful information.
