Applications

Where OASIS comes into play

From greywater reuse to automated physicochemical treatment — an engineered GWTP for buildings, with savings and efficiency.

Commercial and corporate

Greywater reuse in corporate buildings, reducing potable water use for toilet flushing, cleaning and common areas — with direct savings on the water bill.

Industry and manufacturing

Automated physicochemical treatment of low-load effluents, delivering water fit for non-potable reuse in the production process.

Car washes

A compact, customizable solution for reusing wash water, reducing potable water consumption and the business's operating costs.

Frequently asked questions

Greywater reuse plants (GWTP): what you need to know

What is a GWTP?
A GWTP is a greywater treatment plant. OASIS separately collects greywater from showers and washbasins, applies automated physicochemical treatment and returns water fit for non-potable reuse.
What is greywater and how does reuse work?
Greywater is the effluent generated by showers and washbasins. In greywater reuse, this effluent is treated and reused for non-potable purposes such as toilet flushing, gardens and cleaning.
How does OASIS physicochemical treatment work?
The physicochemical treatment is automated and works by clarifying the effluent and reducing COD, bringing water quality up to non-potable reuse standards without the need for constant manual operation.
How much potable water can OASIS save?
By replacing potable water with reused water for toilet flushing, gardens and cleaning, the greywater treatment plant can reduce the building's potable water consumption.
What is an effluent treatment skid?
It is a compact, modular system with the treatment equipment integrated on a single base. The OASIS effluent treatment skid is compact and customizable, making installation and integration into the project easier.
