From underground water and sewer infrastructure to technically demanding excavations, discover the experience and practical capability behind Brazzo Civil.
EXPLORE OUR WORK →We work on civil infrastructure projects across NSW, bringing hands-on expertise to complex ground conditions, underground services and construction challenges.
Brazzo Civil delivered sewer and potable water infrastructure across four interconnected stages of the Menangle Park residential development. The works included extensive gravity sewer networks, pressure-rated water mains, maintenance structures, service connections and integration with adjoining stages.

Across Stages 4.1, 4.2, 4.3 and 4.4, Brazzo Civil contributed to the delivery of extensive sewer and potable water infrastructure for a major residential development. The construction scope required careful coordination between adjoining stages, excavation and pipe installation, maintenance structures and connections to existing infrastructure.

Water and sewer main sizes represented in the drawings
Stage 4.1 deep maintenance-hole design detail
The sewer design includes DN150 and DN225 SN8 PVC gravity mains, associated maintenance holes and chambers, and connections between stages. The water designs include DN100, DN150 and DN200 PN16 oPVC mains, hydrants, valves, tees, bends, thrust restraint and property services. Stage 4.4 water drawings are designated “M2M only” and show extensions and connections rather than a separately quantified pipe schedule.
Stage 4.1 incorporates specialist deep sewer infrastructure, including detailed reinforced concrete maintenance-hole construction drawings for depths to invert of up to 15 metres. The project illustrates the team's experience working with complex excavations, underground services, staged construction interfaces and Sydney Water requirements.
Technical quantities above are summed from the issued-for-construction drawing pipe schedules, not independently verified as-built measurements. The 15 m figure refers to the maintenance-hole design detail. Construction plans and the Stage 4.2 quality plan were used as reference documents.
