Municipal water supply interruptions have become a regular reality for residents and businesses in Nelspruit. An off-grid or grid-tied water supply tank system gives you independence from the municipal supply, ensuring you always have access to water for drinking, sanitation, irrigation, and fire protection regardless of what is happening with the municipal network.

Action Plumbing installs, connects, and maintains water storage and supply tank systems for homes and businesses across Nelspruit and the Lowveld. We have been doing this for over 25 years and we know exactly what each property type needs to achieve genuine water independence.

Why Install a Water Supply Tank System?

  • Protection against municipal supply interruptions and water outages
  • Reduced dependence on municipal infrastructure
  • Rainwater harvesting and storage capability
  • Constant water pressure through a dedicated pressure pump
  • Fire protection for rural and estate properties
  • Irrigation supply for gardens and smallholdings
  • Cost savings on municipal water bills over time

Types of Systems We Install

Municipal Backup System

The most common installation for suburban Nelspruit homes. The tank fills from municipal supply whenever pressure is available and switches over automatically when supply fails. Ideal for homeowners who want protection against outages without the complexity of a full off-grid system.

Rainwater Harvesting System

Nelspruit receives excellent summer rainfall, and capturing that rainfall before it runs off is both environmentally sensible and practically valuable. A rainwater harvesting system collects water from your roof, passes it through a first flush diverter, and stores the clean water in storage tanks.

Borehole Supply System

For properties with access to a reliable borehole, a submersible pump feeds water from the borehole into a storage tank for household distribution. Particularly common on smallholdings, agricultural properties, and larger estates in the Nelspruit area.

Full Off-Grid System

A combination of sources — typically rainwater as the primary supply with borehole or tanker delivery as backup — provides complete independence from the municipal network. Increasingly popular on smallholdings around Hazyview, Barberton, and Malelane.

Key Components of a Complete System

Storage tank — food-safe, UV-stabilised polyethylene tanks from established South African manufacturers.

Float valve — automatically fills the tank from the municipal supply when the level drops.

Auto-switchover valve — detects when municipal pressure drops and switches your supply to the tank automatically, then switches back when pressure is restored.

Pressure pump — delivers consistent water pressure throughout the household from the tank. Essential for ground-level installations.

Tank base or stand — a filled 5,000 litre tank weighs 5 tonnes. It must be supported on a solid, level, engineered base. We construct these as part of every installation.

Our Installation Process

  1. Site assessment — we assess your property, water usage, space, and budget.
  2. System design — we design a system sized correctly for your specific needs.
  3. Base preparation — we prepare the tank base or stand to the required standard.
  4. Tank and component installation — tank positioned and connected to inlet, distribution, pump, and switchover.
  5. Testing and commissioning — we test every component and confirm automatic switchover is functioning correctly.
  6. Handover — we walk you through the system operation and maintenance requirements.

Rainwater Harvesting in Nelspruit

Nelspruit receives an average of 700 to 800mm of rainfall per year, concentrated between October and March. A property with a medium-sized roof can realistically collect tens of thousands of litres during a good rainy season. That water, if captured and stored, can supplement or replace municipal supply for non-potable uses including toilet flushing, garden irrigation, and laundry. For drinking and cooking, a filtration and UV sterilisation system can be added.

Frequently Asked Questions

Costs vary depending on tank size, system configuration, and site conditions. Call us on +27 79 979 9131 for a free site assessment and detailed quote.

In almost all ground-level tank installations yes. Without a pump, water pressure from a ground-level tank is insufficient for normal household use.

If the tank is filled from the clean municipal supply, the water is safe to drink. For rainwater harvesting systems, appropriate filtration and UV sterilisation is included in the system design.

Yes. The auto-switchover valve detects when municipal pressure drops and switches automatically. You do not need to do anything.

We recommend annual cleaning and sanitisation to prevent algae growth and bacterial contamination, which is particularly important in Nelspruit's warm climate.

Yes. We design integrated systems that use rainwater as the primary supply and municipal water as a backup to top up the tank when needed.

For most residential installations, planning permission is not required. We can advise based on your specific situation.

We work with all major South African tank brands including JoJo and Polymaster and can advise on the best product for your needs and budget.
