Water case studies
Riverstone Wastewater Treatment Plant
AJM United worked with UGL and other contractors to deliver the first of three major projects on the LSCTP (Lower South Creek Treatment Program). Despite complex challenges, AJM United built a reputation for on-time delivery, high-quality standards, and achieving Zero Harm throughout. The team managed tight window shutdowns and worked against the clock to complete scopes without affecting plant operations.
St Marys Water Recycling Plant
AJM United were one of the first major Structural, Mechanical & Piping (SMP) contractors onsite, playing a large role in the St Marys Water Recycling Plant's reliability and renewal works. The project covered multiple different processing plants, each requiring specialised installation, each serving a vital part of the overall operation.
Quakers Hill Sewerage Treatment Plant
AJM United played a vital role in delivering the new 38 ML/day Biological Nutrient Removal plant with primary sedimentation at Quakers Hill, replacing the existing secondary treatment plant. Described as one of the most challenging projects on the LSCTP Program — and AJM United's proudest achievement on a water treatment project.
