Filter technology already at Port Stewart clarification.

Hello,
What is the iron filtration method used at Port Stewart? From my research, different filters require different maintenance and spatial needs, which is key to a great design.

I presume it is an aeration sedimentation filter but the concrete tank near the elevated water tanks has no clear way of removing the iron sludge build-up (or is this just another water tank?).

In a EWB video conference on 13 March 2026, Alex Gartrell mentions that this iron filter is not working as it was not maintained properly. I would like to know what part of the filter was not maintained properly. From my research aeration filters struggle with water with iron levels over 10mg/L. The Port Stewart has been reported to be higher than 30mg/L sometimes.

And how much of an impact would the corroded pipes and misplaced river water inlet also have on the performance of the filter system.

Thank you, Ryan.
