Biozone

Backup Water Systems for Gauteng Homes, Schools, Hospitals and Businesses

Keep water available, and make the water you fall back on fit to use.

Biozone designs backup water systems for homes, schools, hospitals and businesses across Gauteng, using borehole water, municipal water held in storage or an alternate water source. Every site is different, so we start with an application assessment. A Biozone engineer looks at your water source, your water quality and how you use water, and only then do we design your system.

Backup water you can use, not only store

A backup supply is only useful if the water in it is fit for the job you need it for. Water from a borehole, water from an alternate source and municipal water held in storage each need to be looked at on their own terms.

That is why Biozone looks at the quality of your backup water, not only at storage. Your water is analysed by an external laboratory first, and any treatment stages are designed for your site.

More than a water tank

A tank stores water. A backup water system also has to deliver water that suits the way your home, school, hospital or business uses it. That is why every Biozone backup water system is designed around three things:

Where the backup water comes from

How it is stored

Which treatment stages it needs

What your system includes is confirmed only after we have assessed your site.

Johannesburg water supply: what Johannesburg Water has said

Planning a backup supply now means you choose the source, the storage and the treatment, instead of deciding during an interruption.

Backup water for homes, schools, hospitals and businesses

Homes

For households, a backup water system is about keeping water available for the kitchen, bathrooms and laundry when the municipal supply is interrupted.

We look at your property, your current supply and how your household uses water before we recommend a route, whether that is storage for municipal water with treatment, a borehole or an alternate water source.

Schools

For governing bodies, bursars, principals and facilities managers, backup water is about planning for municipal interruptions so that water stays available for toilets, hand-washing, kitchens and cleaning.

Hospitals, clinics and healthcare facilities

For facility and maintenance managers, a backup water system is about keeping water available during a municipal interruption, with any treatment stages designed so that the backup water is fit for each use on site.

Hospitals, clinics, frail care centres and other healthcare facilities use water for kitchens, laundry, cleaning, sanitation and building services, often around the clock.

Every healthcare facility is different, so a Biozone engineer assesses your site, your water source and how water is used before anything is designed. In Johannesburg, Helen Joseph Hospital uses borehole water treated by a Biozone system.

Businesses and facilities

Offices, workshops, factories, hospitality venues, retail sites and other facilities each use water differently.

Tell us what your operation needs water for, and we will design the backup system around that demand.

Two routes to a backup water system

Biozone can back up municipal water, borehole water or an alternate water source. Which route suits you depends on your site, and we confirm what your system includes only after we have assessed it.

Route 1

A borehole or an alternate water source

If you want a water source of your own, Biozone guides you on borehole drilling, or helps you find an alternate water source. Your water is analysed by an external laboratory, and we then design the backup water treatment system around the results.

Already have a borehole and only need it treated? See our borehole water treatment systems.

Route 2

Municipal water backup, with storage and treatment

If you would rather back up your municipal supply, Biozone provides water storage that fills while municipal water is available, plus treatment stages for the stored water that is fed to your home, school, hospital or business.

How a Biozone backup water project works

1

Application assessment (free)

A Biozone engineer visits your site and looks at your current water source and what you need water for.

2

Water analysis

Your water is analysed by an external laboratory. Testing parameters follow SANS 241.

3

System design and full quote

We design the source, storage and treatment stages your site needs, and you get a full quote according to your site's needs and the water analysis. No two systems are the same.

4

Installation

Biozone installs your system and connects it to your site.

5

Maintenance and service

Biozone maintains and services your system after installation.

Krugersdorp High School: a Gauteng school backup water example

Borehole treatment skid at Krugersdorp High School, Krugersdorp, Gauteng Biozone filtration vessels and dosing tanks on a Krugersdorp High School treatment skid, with water storage tanks behind

Krugersdorp High School needed a borehole water treatment system to provide an emergency backup water supply during municipal water interruptions, using its existing borehole water and storage infrastructure.

Laboratory analyses showed that water from both boreholes tends to be corrosive, with low alkalinity. Biozone designed two skid-mounted borehole treatment systems, rated at 2,000 L/h for each borehole:

  • AFM filtration, granular activated carbon (GAC), pH and alkalinity correction, and sodium hypochlorite dosing
  • A design capacity of 2,000 L/h per skid
  • Eight existing 5,000 L tanks, giving 40,000 L of treated backup storage
  • Timer-controlled recirculation to reduce stagnation while the system is on standby
  • Installed and commissioned in October 2026

No reverse osmosis or specialised metals-removal stage was considered necessary based on the available results.

Backup water systems: frequently asked questions

What is a backup water system?

A backup water system (also called a water backup system) gives your home, school, hospital or business a second supply of water to use when the main supply is interrupted. With Biozone, that backup comes from a borehole, an alternate water source or municipal water held in storage, together with treatment stages designed for your site.

What does a Biozone backup water system include?

That depends on your site. Every customer's requirements are different, so we do not sell a standard package. A Biozone engineer assesses your site first, and the system is designed from that assessment.

Is a backup water system just a tank and a pump?

Storage is one part of it. Biozone also looks at where the backup water comes from and at its quality, and designs any treatment stages so the water you fall back on is fit for the way you use it.

Do you install backup water systems for homes?

Yes. We look at your property, your current supply and how your household uses water, and then recommend a route: storage for municipal water with treatment, a borehole or an alternate water source.

Can a school get a backup water system?

Yes. Biozone designs backup water systems for schools to keep water available for toilets, hand-washing, kitchens and cleaning during municipal interruptions. Krugersdorp High School is one example.

Do you design backup water systems for hospitals and clinics?

Yes. Hospitals, clinics and other healthcare facilities each use water differently, so a Biozone engineer assesses the site, the water source and how water is used on site. The system is then designed to keep water available and fit for each use.

Do you design backup water systems for businesses?

Yes. Offices, factories, workshops, hospitality venues and other facilities each have their own water demand. We design the backup system around what your operation needs water for.

Can you back up borehole, municipal or alternate water sources?

Yes. A Biozone backup supply can come from a borehole, an alternate water source or municipal water held in storage. With municipal water, we provide storage that fills while municipal water is available, plus treatment stages for the stored water.

I don't have a borehole. Can you still help?

Yes. Biozone can guide you on borehole drilling, or help you find an alternate water source. Your water is analysed by an external laboratory, and then we design the backup water treatment system. If you would rather not use a borehole, we can look at storing and treating municipal water instead.

I already have a borehole. Is this the right page?

If you already have a borehole and only need its water treated, see our borehole water treatment systems. If you want a backup supply planned as a whole, including storage, start with an application assessment here.

Should I choose a borehole or municipal water for backup?

It depends on your site, your water quality and what you need the water for. We help you compare the options during your application assessment.

Why does backup water need treatment?

Stored water, borehole water and water from alternate sources each have their own quality to manage. Treatment stages are designed so that the water you fall back on is fit for the way you use it.

Who analyses the water?

Water analyses are done by an external laboratory. Testing parameters follow SANS 241.

Do you install and maintain the system?

Yes. All Biozone systems are installed, maintained and serviced by Biozone.

How much does a backup water system cost?

It depends on your water source, your site and what the system needs to supply, so we don't publish a standard price. Start with a free application assessment with a Biozone engineer.

What happens during the application assessment?

A Biozone engineer visits your site and looks at your current water source and what you need water for. You then receive a full quote according to your site's needs and the water analysis.

Is the application assessment free?

Yes. It includes a site visit and a full quote according to your site's needs and the water analysis. Request an application assessment with a Biozone engineer using the form on this page, or call +27 67 972 2169 or +27 11 791 4403.
