Pilot architecture for contaminated liquid remediation with intake protection, oil/solids separation, final filtration, verification sensors, startup checks, staged shutdowns, and auditable routing to discharge, recirculation, or hold.

Water treatment — RO systems, UV sterilisation, bicarbonate adjustment, rainwater harvesting, grey water recycling. Distinct from pyfarm-irrigation (scheduling) and pyfarm-hydroponics (nutrient solution). Source water quality is a prerequisite for both.
