Rainwater Harvesting for Irrigation in Surrey
Turn rainfall into irrigation water. Rainwater harvesting captures roof runoff, filters it and stores it underground or above ground, then pumps it through your irrigation system. For Surrey gardens on metered mains, a rainwater system can cut irrigation water costs dramatically while keeping the garden green through hosepipe bans.
Why It Matters
The difference engineered irrigation makes
Lower water bills
Rainwater is free; once the system is installed, every litre used for irrigation is a litre you do not buy from the mains.
Hosepipe-ban proof
Stored rainwater is not subject to hosepipe bans, so your garden stays watered when mains irrigation is restricted.
Better for plants
Rainwater is naturally soft and free of chlorine, making it better for acid-loving plants, seedlings and ericaceous planting.
Flood and runoff control
A large storage tank attenuates roof runoff during heavy rain, reducing surface water discharge from your property.

Technical Considerations
How it works
Rainwater harvesting for irrigation captures roof runoff through a filter that removes leaves and debris, stores it in an underground or above-ground tank, and pumps it through the irrigation system on demand. The tank is sized to the roof catchment area and the garden's irrigation demand, with mains top-up for dry periods if required. A submersible pump with pressure switch delivers water to the irrigation zones, and a filter at the pump protects drip emitters from any residual sediment.
