Pumps, relays, filters, lifts, and barriers wear according to use. The Board’s maintenance calendar assigns inspection windows, parts priority, and access control so crews can work before a small fault becomes a route-wide interruption.

A delayed repair receives a new entry, not a vanished one. Ward offices can see the service class, assigned crew, and next review point through the local desk.

Residents help by reporting a fault’s location, sound, and visible condition. Technical conclusions remain with qualified crews.
