How it works
Backup Water for East Rand Homes: Kempton Park, Benoni and Boksburg
By the WaterQuotes team · Published 2026-10-13 · 6 min read
Rand Water supplies bulk water to Ekurhuleni, and Ekurhuleni distributes it to homes across Kempton Park, Benoni, Boksburg and the wider East Rand. When either layer of that chain goes offline — planned maintenance, a burst main or load-shedding affecting pump stations — taps in all three towns can run dry with little notice. This guide explains how to size and install a tank-and-pump backup system suited to East Rand conditions, without overpromising what any single solution can do.
Why East Rand Supply Interruptions Happen
The East Rand sits at the end of a long bulk-supply chain. Rand Water abstracts, treats and pumps water from source to Ekurhuleni’s reservoir network; Ekurhuleni then re-pumps it through local distribution mains to your tap. A fault anywhere along that chain — a Rand Water pump station going offline, an Ekurhuleni feeder main bursting, or load-shedding killing a booster pump — can produce a no-water event lasting hours or, in some cases, days.
For background on how Rand Water bulk outages actually work and what triggers them, the article Rand Water shutdowns explained covers the mechanics in plain terms. Understanding that system helps you appreciate why a local backup — one that sits entirely on your property — is the most reliable insurance available to an individual homeowner.
It is also worth knowing that Johannesburg Water (a separate utility covering the City of Johannesburg rather than Ekurhuleni) has reported non-revenue water of 44.8% in its 2024/25 audited figures, suggesting the broader Gauteng network has significant infrastructure stress. Ekurhuleni’s own figures will differ, but the pattern of an ageing bulk-water network under pressure is consistent across the East Rand.
How Much Water Does an East Rand Household Actually Need?
Sizing a backup tank starts with consumption. South Africans use on average about 237 litres per person per day according to IWA Water Policy data — noticeably above the world average of roughly 173 litres. That figure covers drinking, cooking, bathing, toilet flushing and garden use.
For backup purposes, most households sensibly reduce their daily draw. Running a backup system is not normal life: short showers replace baths, garden irrigation stops, and dishwashers may sit idle. A conservative planning figure for an active backup period is around 80–120 litres per person per day, though your household’s actual habits will vary.
A family of four at 100 litres per person per day needs roughly 400 litres daily. A three-day backup buffer therefore requires about 1,200 litres; five days takes you to 2,000 litres. For a more detailed walkthrough of this calculation — including how to handle three-day versus longer outage scenarios — the guide sizing a backup water system for a 3-day outage goes step by step.
For East Rand homes, 2,000–5,000 litre tank capacities are common. Larger stands in Benoni or Boksburg sometimes accommodate 10,000 litre tanks, which is worthwhile if you have the space and budget.
Tank-and-Pump System Components
A complete backup system has three core elements:
| Component | What it does | Rough Johannesburg reference cost |
|---|---|---|
| Storage tank (poly or JoJo) | Holds mains water while pressure is available | Included in system price |
| Transfer/booster pump | Pressurises the stored water to your house | Part of installed system |
| Level controls and valves | Fills tank automatically; switches to backup on mains loss | Included in system price |
As a Johannesburg reference point (East Rand prices may differ — always confirm via quotes), backup tank-and-pump systems typically run R20,000–R40,000 for a straightforward installation, with whole-house configurations around R55,000. A reputable installer should be able to give you a fixed quote once they have assessed your stand, existing plumbing and preferred tank position.
The system works passively: the tank fills from mains whenever supply is present, and an automatic valve or float switch prevents overflow. When mains pressure drops, the booster pump takes over and maintains pressure to your taps. Quality of installation matters — a poorly placed tank or undersized pump creates its own problems.

Borehole as an Alternative or Supplement
Some East Rand homeowners consider a borehole rather than — or alongside — a mains-fed backup tank. Boreholes are independent of Ekurhuleni supply entirely, which is their main advantage. However, the East Rand sits on dolomitic and varied geological ground, and borehole yield, depth and water quality vary significantly between suburbs and even between adjacent stands.
For a realistic picture of what borehole drilling involves in this part of Gauteng, the article borehole drilling on the East Rand covers local conditions. As a Johannesburg reference point only, complete borehole systems typically run R40,000–R150,000, with most falling between R60,000 and R100,000 — East Rand pricing should be confirmed with local drillers.
Any borehole water intended for drinking must be tested against SANS 241 (2024 edition), the South African drinking-water quality standard. Many East Rand boreholes are suitable for garden irrigation and toilet flushing without treatment, but require additional filtration or purification for potable use.
Practical Installation Considerations for Kempton Park, Benoni and Boksburg
East Rand homes vary widely — from compact Kempton Park townhouses to large Benoni smallholdings — so no single configuration suits everyone. A few practical points:
- Space: Poly tanks need a level, stable base. A 5,000 litre vertical tank is roughly 1.8 m in diameter and 2.1 m tall; confirm your stand has room before specifying.
- Access for tanker refill: If an extended outage exhausts your tank, a tanker delivery is the backup to your backup. Ensure the tank fill point is accessible from your driveway or street.
- Pump power: Most booster pumps draw 0.5–1.5 kW. If you want the system to work during load-shedding, budget for a small inverter or generator feed — this adds cost but is often worth it.
- Bylaws: Ekurhuleni’s water bylaws govern connections to the municipal supply. A reputable installer will be familiar with local requirements; confirm this before signing any quote.

Getting the Right Quote
Backup water systems are not off-the-shelf products. The correct tank size, pump specification, pipe routing and switchover mechanism depend on your stand, your household size and your budget. Two homes on the same street can have meaningfully different optimal systems.
The most useful thing you can do before committing is to get at least three quotes from installers who will assess your property in person. Ask each one to specify tank capacity, pump model and output pressure, what happens during load-shedding, and what warranty applies to parts and labour. Written, itemised quotes make comparison straightforward and protect you if anything is disputed later.

Quick answers
How long will a backup tank last during a typical East Rand outage?
That depends entirely on your tank size and household consumption. As a rough guide, a 2,000 litre tank used conservatively by a family of four — at around 100 litres per person per day — would last approximately five days. Most Ekurhuleni supply interruptions resolve within 24–48 hours, so a 2,000–3,000 litre system covers the majority of real-world events. Size up if you have a larger household or want a longer buffer.
Does a backup tank work during load-shedding?
A standard tank-and-pump system requires electricity to run the booster pump. Without a backup power source, the pump will not pressurise stored water during load-shedding. If this is a concern — and on the East Rand it often is, since Ekurhuleni pump stations can also be affected — ask your installer to quote for an inverter feed or generator connection alongside the water system.
Do I need Ekurhuleni permission to install a backup tank?
Ekurhuleni's water bylaws regulate connections to the municipal supply network, so any system that ties into your existing plumbing technically falls under those rules. A reputable installer will know the current local requirements and should handle or advise on any necessary notifications. It is worth confirming this directly when requesting quotes.
Can I use borehole water for drinking in Kempton Park or Benoni?
Possibly, but you must have the water tested before drinking it. SANS 241 (2024 edition) is the South African standard for potable water quality, and borehole water must meet those parameters. Many East Rand boreholes carry iron, manganese or bacterial contamination that requires treatment. A water test from a SANAS-accredited laboratory will tell you exactly what, if any, treatment is needed.
What is a realistic installed cost for a backup tank system on the East Rand?
Using Johannesburg figures as a reference point — since East Rand pricing can vary — straightforward tank-and-pump backup systems typically run R20,000–R40,000, with whole-house configurations around R55,000. These figures should be treated as a starting benchmark only; actual East Rand costs depend on tank size, pump specification, site conditions and the installer. Getting three itemised quotes is the only reliable way to establish a real number for your property.
