What We Do

Watermark Projects, a division of the WA Cooke group, work with companies to reduce the financial and operational cost of their wastewater treatment. We help identify the best wastewater treatment process for the site specific effluent and provide assistance on moving forward...


At the forefront of the Watermark Projects product range are our Dissolved Air Flotation systems which are designed and manufactured in-house.

The Watermark Projects DAF systems are designed to offer a complete wastewater treatment solution with on board chemical mixing vessels, dilute polymer make-up system, complete PLC control panel, pH control and level controllers for automatic operation.

The Watermark Projects DAF range can offer our industrial clients removal rates of up to:

80% of chemical oxygen demand (COD)

98% of total suspended solids (TSS)

99% of fats oils and greases (FOG)

Removal Rates


Every site is different. The wastewater will vary and so will the solution. This is why we'll undertake a lab analysis of your wastewater to indentify the most effective treatment solution for your waste.

This analysis will allow us to determine achievable removal rates with contaminants such as COD, Suspended Solids, FatsOils & Greases as well as pH correction.
