How it works
A second use
for bath and
shower water.
Aqua Gratis collects water from baths and showers, filters it and uses it again to flush toilets. The control panel manages the flow of water and the cleaning of the filters.
How it works
From the shower
to the next flush.
Follow the water through Aqua Gratis, from the moment it leaves the shower to the next time a cistern refills.
Collect
Water leaving the bath or shower flows into the system. The first filter catches hair.
Filter
The water passes through a series of tanks. Particles settle out and finer filters trap smaller debris.
Store
The filtered water stays in the unit until a toilet cistern needs to refill.
Flush
Reused water feeds a dedicated cistern by gravity, or a pump supplies toilets on the floor above.
Installation planning
Where can
the system go?
Aqua Gratis can sit beside a WC, elsewhere in the building, or in a suitable external enclosure. The layout determines which connections and access space the design team needs to allow for.
Bring these details
to the design review.
- Water sources and toilets
- Mark the baths, showers and toilets on the floor plans. Include levels so Cascade can assess gravity and pumped routes.
- Access for servicing
- Show the proposed position, access doors and available space. Ask for the current service clearances for the chosen configuration.
- External siting
- If internal space is tight, share the enclosure location and proposed pipe routes for a site-specific review.
System option
Recover heat
from the shower.
Any Aqua Gratis configuration can be ordered with an integrated Zypho heat exchanger. Heat from the outgoing shower water warms the incoming cold supply through separate channels.
