FAQs About Effluent Tanks

Which effluent tank capacity do I need?

This will all depend on how many people are using your toilets, showers or other units every day, and how frequently you’ll be having the tank emptied. We can review your site, occupancy and preferred service intervals to recommend the ideal standard size or custom tank for your needs.

Are ModCon’s above ground effluent tanks long lasting?

Absolutely. Every tank is built from fully welded 3mm steel and is engineered to cope with harsh waste environments, heavy use and outdoor conditions. Sit-on models are reinforced inside to support cabin loads, delivering a durable, low-maintenance tank that performs reliably for years.

Can your effluent tanks be emptied easily? 

Yes – their overground location means no groundwork is required, so access is simple. Each tank also includes easily accessible service points, so waste contractors can empty them quickly.
