Ireland; Rainwater Harvesting System

1. Water is a scarce and increasingly expensive resource and Government policy and new building
regulation require the installation of water conservation measures. Today, planning consent and
the award of Government building contracts is often conditional on being able to meet new water
conservation standards.
A typical family uses 70,000 litres of mains water each year for toilet flushing, laundry
and garden irrigation and much of this could be replaced with harvested rainwater. Toilet flushing
alone accounts for 30% of water usage in most homes. Actual savings depend on local rainfall
patterns, the size of the roof catchment and the space available for water storage. The potential
mains water savings in a light commercial building can be up to 80% of consumption.
By At Halsted Rain we understand that installing a rainwater harvesting system is often a compromise
between available space, the utility required and budget. That is why we have designed a state-of-
the-art above ground rainwater utilisation system for toilet flushing and micro irrigation that is
visually discreet, easy to install and above all reliable. It is ideal for new build and retrofit projects
alike. The system is modular and easy to configure to a range of layouts to make best use of the
Rainwater Harvesting Systems available space. Multiple tanks can be joined together using the coupling provided to achieve the
desired rainwater storage capacity.

The Halsted Rain Ultra Slim integrated system comprises a filter, storage tank, delivery pump and
mains top up valve. Rain falling on a roof is channelled via the existing gutters and down pipe to a
filter which removes leaf litter and other debris before diverting the water into a storage tank. The
filter is mostly self cleaning and the tank is purpose designed to protect the quality of filtered
rainwater during storage.
When a service demands rainwater a pump is automatically activated by a pressure switch to
draw water from the tank. The flow rate is sufficient to refill a modern toilet cistern in less than a
minute and other pump models are available for heavier duty requirements. In the event that
demand exceeds the availability of rainwater, a mains water valve is automatically opened to
Simple - Reliable - Affordable partly refill the tank. The mains valve kit comprises a valve, float switch and tundish to comply with
water regulations.
The tanks are easy to install on a wall or integrate into a boundary fence using the steel support frame provided. The filter is installed in the existing down pipe
and the pump and mains valve either inside the property or outside in a protective enclosure.
Services can be fed directly as depicted in the schematic below or indirectly by gravity via a header tank.
1. Rainwater filter, diverter, tank overflow & back flow prevention.
2. Rainwater tanks with steel tubular support frame.
3. Insulated tank outlet & cable to float switch.
4. On demand wall mounted delivery pump.
5. Rainwater main to services.
6. Garden watering via rose gun.
7. Mains top up via valve connected to float switch and tundish.
