Wastewater Management Solutions

Wastewater comes in different forms, each with challenges for storage and management. Poly Synthesis understands these distinctions and offers custom poly tanks for various wastewater streams.

Greywater Tanks

Greywater is the relatively clean wastewater from showers, sinks, and laundry. Our greywater tanks allow safe storage and potential reuse for irrigation or other non-potable purposes, promoting water conservation.

Blackwater Tanks

Blackwater such as wastewater from toilets, requires specialised handling. Our blackwater tanks ensure secure containment, preventing leaks and contamination while facilitating proper treatment and disposal.

Sullage Tanks

Industrial processes often generate sullage, and wastewater that may contain chemicals or contaminants. Our custom-designed sullage tanks are built to handle the challenges of industrial wastewater.

Whatever your wastewater source or composition, Poly Synthesis offers a range of custom-fabricated tanks that comply with regulations and standards.
