Rainwater Harvesting Systems
Clean, stored rainwater systems for Homes & Businesses — collected from your roof, filtered for use, and available on demand regardless of municipal supply or water restrictions. Explore modern rainwater harvesting systems designed for reliable off-grid water supply and long-term water security.
Municipal water is becoming less reliable, and more expensive
Water restrictions, ageing infrastructure, and supply failures are an increasing reality across South Africa — and the Garden Route is no exception. A rainwater harvesting system gives you a private, independent water supply collected directly from your roof, stored in tanks on your property, and filtered to the quality your household or business needs.
Whether you want to supplement your municipal supply, reduce your water bill, or achieve complete water independence, we design and install rainwater harvesting systems and rainwater tanks tailored to your property and usage.
What is a Rainwater Harvesting System?
A rainwater harvesting system collects rainwater from your roof via your gutters, filters out debris and contaminants, and stores it in one or more tanks for use across your property. A pump delivers water on demand to the points where you need it — garden irrigation, toilets, laundry, or with the right filtration, fully potable drinking water throughout the home.
These rainwater harvesting systems are part of a wider category of water harvesting systems and water storage systems for homes and smallholdings.
The result:
- Reduced reliance on municipal water supply
- Lower monthly water bills
- A reliable water reserve during restrictions or supply failures
- Complete water independence where the system and rainfall allow
- Improved water security through decentralised rainwater collection and storage systems
Is a Rainwater Harvesting System Right for You?
Rainwater harvesting systems are ideal for:
Residential homes
Homeowners wanting to reduce their municipal water bill, build a reserve against water restrictions, or achieve full water independence for their property using residential rainwater collection systems and rainwater tanks.
Rural homes & smallholdings
Rural properties with high water demand for irrigation, livestock, and operations — where a reliable, independent water supply is essential to the running of the smallholding. Often paired with water storage systems for smallholdings and solar water pumping systems.
Guesthouses & Airbnbs
Uninterrupted water supply for guests, regardless of municipal restrictions or pressure failures — protecting your reviews and your reputation.
Businesses
Commercial properties wanting to reduce operating costs, meet sustainability targets, or protect critical operations from municipal supply disruptions using commercial rainwater harvesting systems and water backup systems.
How it works
1
Site Assessment
We assess your roof catchment area, average local rainfall, water usage, and how you want to use the harvested water — giving us everything needed to design a system correctly sized for your property and demand.
2
System Design
We design a custom rainwater harvesting system — the right tank capacity, filtration level, pump specification, and distribution layout — matched to your actual water needs and intended use, whether that is garden irrigation, household supply, or fully potable water. This includes selection of rainwater harvesting tanks and system components for long-term performance.
3
Installation
Professional installation by experienced water system installers. Guttering, first-flush diverters, filtration, tank placement, pump, pressure system, and full connection to your distribution points — all installed neatly and correctly. We also provide full rainwater tank installation and complete water system installation services.
4
Support & Maintenance
Ongoing system checks, filter replacements, tank cleaning, and pump servicing keep your water supply clean and your system performing reliably. We are your long-term water independence partner — not just a once-off installer. Maintenance includes rainwater system servicing and water filter replacement services where required.

Frequently Asked Questions
Yes, with the correct filtration. A properly specified multi-stage filtration system — including sediment filtration, activated carbon, and UV sterilisation — produces water that meets potable standards. We design filtration to match your intended use, whether that is garden irrigation, household grey water, or fully potable supply.
Collection volume depends on your roof catchment area and your local rainfall. The Garden Route receives some of the highest rainfall in South Africa, making it one of the most viable regions for rainwater harvesting. We calculate your realistic yield during the site assessment based on your specific roof area and local rainfall data.
A first-flush diverter automatically discards the first flow of water from your roof at the start of rainfall — the water most likely to carry bird droppings, dust, and debris — before directing the cleaner flow that follows into your storage tanks. It is a standard component of any properly designed system and significantly improves the quality of collected water.
Yes. Most residential systems are designed with an automatic switchover that draws from rainwater tanks first and switches to municipal supply when tanks run low. This maximises your use of harvested water while ensuring continuity of supply at all times. These hybrid setups are common in modern water backup systems.
Yes — and it is something we actively encourage. A solar-powered pump removes the running cost of your water system entirely, and both systems are designed and installed by the same team. Many of our clients combine solar and rainwater harvesting for complete energy and water independence in a single project. This creates a fully integrated off-grid water system using solar water pumping systems.
