Outfall.
Where the water leaves the site, the design gets serious.
Outfall picks up exactly where Catchment stops, at the edge of the site. Foul & discharge design, phased by paying value: gravity and pumped foul first, then off-mains treatment, building drainage and adoption-ready networks. It sits beside Catchment on one account, one login, one set of projects, one standards discipline.
