Rainwater Harvesting

Rainwater harvesting systems collect roof water for reuse in gardens, toilets, and washing machines, cutting mains water consumption and bills. The right pump delivers stored rainwater reliably to wherever it is needed.

What is Rainwater Harvesting?

Rainwater harvesting captures rainfall from roofs into a storage tank, filters it, and pumps it to points of use. Systems range from a simple water butt and garden pump to full house installations supplying WCs and appliances with automatic mains backup.

How it works

  1. Rainwater drains from the roof through filters into a storage tank.
  2. A submersible or surface pump pressurises the stored water on demand.
  3. A controller manages delivery and switches to mains backup when the tank is low.
  4. Harvested water supplies gardens, WCs, and washing machines as designed.

Where is Rainwater Harvesting Used?

Garden Irrigation

Free stored water for hoses, sprinklers, and drip systems.

Toilet Flushing

Substituting mains water for a major household use.

Washing Machines

Soft rainwater reduces detergent use and scale.

Commercial Buildings

Large roof areas serving wash-down and WC demand.

How to determine which Rainwater Harvesting solution is the one you need?

System Scale

Garden-only systems differ greatly from whole-house installations.

Tank Position

Underground, surface, or slimline tanks affect pump selection.

Pump Type

Submersible pumps sit in the tank; surface pumps draw from it.

Mains Backup

Automatic changeover keeps WCs working through dry spells.

Comparing Types of Rainwater Harvesting Equipment

Submersible Harvesting Pumps

Quiet in-tank pumps with floating suction options.

Surface Booster Pumps

Self-priming pumps mounted near the tank.

Packaged Control Units

Pump, controls, and mains backup in one assembly.

Garden Rainwater Pumps

Simple pumps for butt and tank irrigation use.

FAQs

Is harvested rainwater safe to drink?

No, standard systems supply non-potable uses only, such as WCs, gardens, and washing machines; drinking water requires advanced treatment.

How much mains water can I save?

Toilets and gardens account for a substantial share of consumption, so well-sized systems commonly cut mains use by around 40 to 50 percent.

What happens when the tank runs dry?

Whole-house systems include automatic mains backup, so WCs and appliances continue working seamlessly.

Do I need a filter?

Yes, pre-tank filtration removes leaves and debris, protecting water quality and the pump.

Which pump is best for rainwater?

Submersible pumps with floating suction draw the cleanest water and run quietly; surface pumps suit accessible above-ground tanks.

Troubleshooting your Rainwater Harvesting System

Poor water quality: Clean the pre-tank filter and check the calmed inlet and floating suction.
Pump running with no demand: Investigate leaks or a passing non-return valve in the distribution.
No water at outlets: Check tank level, pump operation, and the mains backup changeover.
