Garden System
Goto below ground systems
Key Benefits:
More storage than a water butt
Stores a useful volume of rainwater for gardens, ponds, greenhouses and outdoor cleaning.
Cleaner rainwater
A stainless steel Wisy downpipe filter removes leaves, moss, insects and debris before water enters the tank.
Automatic pumped supply
The pump starts when a tap or outlet is opened, giving convenient pressurised rainwater for everyday garden use.
Naturally soft water
Rainwater is ideal for plants, especially lime-sensitive species, and useful for car washing and outdoor cleaning.
Simple above-ground installation
A practical option where a below-ground tank is not required. See our Below Ground Systems for higher-capacity buried storage.
Above Ground Rainwater Harvesting for Gardens
The Rainsava Above Ground Garden System is designed for gardeners who want a cleaner, more capable alternative to a standard water butt.
Rainwater from the roof is filtered at the downpipe before entering the storage tank. It can then be pumped automatically to garden taps, hoses, sprinklers, ponds and outdoor cleaning points.
The system is supplied as a package with the main components ready for assembly, including an above-ground polyethylene tank, Wisy downpipe filter, pump and suction filter.
Tank sizes start from 400 litres, with larger tanks and linked systems available for gardens with greater water demand.
Ideal Uses
- Garden watering
- Greenhouses and vegetable gardens
- Ponds and water features
- Sprinklers and irrigation

Outdoor cleaning
