There are four key elements to the new iNDUS system. First, there’s a new toilet that comes with a macerator and makes use of the motorhome’s grey water to produce a long or short flush. It also comes with a soft-close lid and is plumbed into a black water tank.

Second, the system has a dosing module, with chemicals for the black water, the grey water system and the toilet flush, that ensures exactly the right amount is used for each.

Third, there’s a clever discharge pod, which is attached to a length of wide bore hose, and empties grey and black water together at an onsite drain point. Finally there’s an app to monitor levels that tells you when to empty or recharge, and points you to the nearest emptying point.

Bürstner has already introduced the system to its 2021-season Elegance, launching soon, and we’re told Adria is well advanced in integrating the system.
