How big should my backup tank be?

Tank size follows from your daily consumption and how long you need to run without supply. Essential-use-only backup needs far less storage than running a property normally for several days.

Will the system work during load shedding?

Pumps need power. If continuity during a power outage is a requirement, that has to be part of the design — for example through gravity-fed elements or a suitable power backup arrangement.

Does stored water go stale?

Stored water can deteriorate if it stands unused and unprotected. Systems are best designed so that stored water circulates through normal use, and filtration or treatment can be added where appropriate.

Can a backup system be added to an existing borehole?

Often, yes. Boreholes, rainwater harvesting and municipal supply can be integrated into a single storage and pressure system with the right controls.

Water Backup Systems

A water backup system keeps a property functioning when the municipal supply is interrupted or pressure drops. Designing one properly means answering a simple question first: how much water does this property need, and for how long?

Backup water storage tanks connected to booster pumps and a pressure vessel at a property

When a backup system makes sense

Municipal interruptions, planned or unplanned
Low water pressure that affects daily use
Increased household demand as a family or property grows
Business continuity where an interruption stops trading
Property developments needing reliable supply across multiple units
Emergency water requirements for essential use

What a system may include

Water storage tanks sized to the required backup duration
Booster pumps to deliver usable flow and pressure
Pressure systems and vessels for stable supply
Automatic changeover solutions between municipal and stored water
Pump controllers and protection against dry running
Integrated water systems combining municipal, borehole or rainwater sources

Why the design differs per property

The correct system depends on water demand, property layout, available infrastructure and required backup duration. A townhouse that needs a few hours of continuity is a very different design to a guesthouse that must operate normally for two days. Tank position, pipe routes, available space and electrical supply all influence what is practical.

How it works

The water backup systems process

A structured sequence so that what gets installed matches what the property actually needs.

01
Demand review
We establish actual consumption and the backup duration you need.
02
System design
Storage volume, pump duty, pressure control and changeover method are specified.
03
Installation
Tanks, pumps, controls and pipework are installed and integrated.
04
Commissioning & service
The system is tested under load and maintenance intervals are agreed.

Before you commit

What to consider

Points worth thinking through — whether you appoint us or someone else.

Daily consumption and which uses are essential during an outage
How long the property needs to run on stored water
Where tanks can be located, and the load-bearing surface required
Whether the system should switch over automatically or manually
How stored water quality will be maintained over time
Electrical supply for pumps, and behaviour during a power outage

Assess first

We look at the property and the requirement before recommending equipment.

Clear scope

You are told what is included, what is not, and what depends on site findings.

No overselling

Where a smaller solution will do the job, that is what we will propose.

Ongoing support

Maintenance can be arranged so the system keeps performing after handover.
