Treatment Solutions
for complex flows

Process Scope

Water + Waste

Liquids, gas, and by-products

Delivery Model

Tailored

Often with specialist consultants

Outcome

Efficient

Process-led tank performance

Developed beyond storage

Timbertanks now support increasingly sophisticated treatment duties for water, waste, and process streams.

Biogas capture Clarifiers Leachate collection

Continuous research and development has extended the original Timbertank concept well beyond potable water. We regularly work alongside engineers and design consultants to match liner selection, geometry, and detailing to the process.

Project approach

Designed around treatment performance, site realities, and long-term operating value.

Biodigesters
that recover value

Timbertanks are increasingly used in biodigester systems to capture and store biogas produced during sewage and effluent treatment. The tank stores methane-rich gas so it can be returned to the digestor as heating fuel or used within a wider energy-recovery process.

That closed-loop approach improves treatment economics while turning waste into a useful resource. The same concept can be applied across agricultural and industrial sites where organic waste streams are generated at scale.

Gas capture

Designed to safely hold biogas generated during sewage and effluent digestion.

Energy loop

Stored methane can be directed back into the process as heating fuel or site energy input.

Operational benefit

Supports better waste outcomes while adding practical value for farm and treatment operators.

Clarifiers
for treatment plants

Timbertank reservoirs are used extensively in large-scale local authority and industrial clarifier projects. Working with specialist consultants, they can be specified as filters, sand filters, stage tanks, aeration tanks, and clarifiers within wastewater and water-treatment plants.

The format is well suited to treatment infrastructure that needs robust containment, efficient on-site construction, and a tank designed around the role it plays in the wider process sequence.

Leachate collectors
for landfill runoff control

Timbertank reservoirs are increasingly being used to collect the water that flows through landfills. In that role, they provide a durable lined containment system for managing contaminated runoff in a controlled and serviceable way.

On-site construction and flexible tank geometry make them a practical fit for landfill environments where access, staging, and available footprint can all be constrained by the operating site.

Collection duty

Captures and contains water moving through active landfill cells

Site fit

Flexible sizing and on-site build suit constrained waste-management sites

Containment approach

Specified liners and detailing matched to the collection environment
