A municipal supply scheme covering intake, treatment, storage and 46 km of distribution network, delivered through occupied streets with continuity of existing supply maintained.
Existing supply had to remain in service throughout the network replacement.
Utility records were incomplete, with unmapped services beneath most of the alignment.
Street works passed through commercial areas where access loss directly affects trading.
The network was replaced zone by zone with temporary over-ground bypasses, so no household lost supply for more than a scheduled window.
Service detection and trial pitting preceded every excavation, and the resulting records were handed back to the municipality as an updated utility map.
Commercial-area works were sequenced into short lengths with same-day reinstatement, and traders were notified a week in advance.
Watertightness and pressure testing were completed before backfill on every section, with results held in a single traceable register.
