Water Backup Systems

When the municipality cuts supply or a power outage runs dry your taps, a correctly sized water backup system keeps your home or business running. We design and install them across Gauteng, North West and Limpopo.

Natural water flow backup source

Load shedding, ageing municipal infrastructure and increased demand mean water interruptions are common across Gauteng, North West and Limpopo. A backup water system is no longer a luxury — it is practical insurance.

Hard Rock Borehole Drilling and Installation designs backup systems around your actual daily water demand, not a standard package. A small household needs a different solution from a farm or a commercial facility. We get that right from the start.

What We Install

Tailored emergency reserves, borehole link integrations, booster combos, and hands-free automatic switches.

Water Storage Tank Installation

A storage tank gives you a reserve supply that keeps water flowing when your main source cuts out. We install tanks sized to your property's daily consumption so you have enough buffer to ride out routine interruptions.

  • Tank sizing and capacity checks based on daily usage
  • Siting layout, slab prep, and inlet/outlet alignment
  • Float valve mechanism and overflow plumbing setup
  • Integration design with your existing home piping

Borehole-Fed Backup Systems

If you have a borehole, it can be configured to automatically fill your backup storage tank. When municipal supply is interrupted, your borehole pump keeps the tank topped up and your taps run as normal. We install the switching logic, pipework and controls to make this work reliably.

This is one of the most effective backup strategies for properties in areas with frequent municipal interruptions.

Pump & Tank Combination Systems

A storage tank alone does not guarantee pressure. A pump and tank combination ensures water moves from the tank to your taps at the pressure your household or business needs.

  • Storage tank coupled with a dedicated transfer pump
  • Pressure vessel tank and pressure switch calibrations
  • Non-return valves and system isolation bypass points
  • Control panels and electric circuit protection relays

Automated Switchover

Manual switchover systems require someone to physically open and close valves when supply changes. Automated switchover eliminates that — when municipal supply drops, the system switches to your backup source without anyone lifting a finger.

  • Municipal-to-tank automatic water switching lines
  • Borehole-to-tank fill controller switches
  • Level-controlled transfer pump triggers
  • Multi-source priority management valves

Common Questions

Find answers about reserve sizing calculations, borehole connections, and system automation.

How big a backup tank do I need?
It depends on your daily water use and how long you need to cover. A typical household uses 150–200 litres per person per day. We calculate the right size when we assess your property.
Can my existing borehole feed the backup tank?
In most cases, yes. We assess your borehole's yield and pump output to confirm it can supply the tank at the rate you need.
What happens when municipal supply comes back on?
With an automated system, the municipal supply resumes filling your tank and the backup source switches off. Nothing to do manually.
Do you install tanks as well, or just the pump systems?
We handle the full installation — tank supply, pump, pipework, controls and commissioning.
