About this role

We are seeking a highly competent and experienced Mechanical Engineer with specialised expertise in estate sewage systems, wastewater management, and stormwater infrastructure to join our project development team.
The successful candidate will be responsible for the planning, design coordination, installation, supervision, testing, and commissioning of sewage treatment systems, wastewater collection networks, pumping stations, stormwater management systems, and related mechanical infrastructure for residential estates, high-rise buildings, duplexes, terraces, and large-scale property development projects.
The ideal candidate must have strong practical experience in estate infrastructure, a solid understanding of mechanical building services, and the ability to coordinate effectively with civil and structural engineers, infrastructure consultants, contractors, and project managers to deliver safe, efficient, and sustainable systems.

Estate Sewage and Wastewater Management:

Plan, coordinate, and supervise the installation of sewage collection, conveyance, treatment, and disposal systems for residential estates and property developments.
Oversee the installation and operation of sewage treatment plants, wastewater treatment facilities, septic systems, and other approved wastewater management solutions.
Review sewage network layouts, pumping arrangements, equipment specifications, and associated mechanical drawings.
Supervise the installation of sewage pumps, lift stations, pumping chambers, valves, pipelines, and related mechanical equipment.
Monitor the performance of sewage and wastewater systems to ensure effective operation, reliability, and compliance with approved design requirements.
Identify and resolve issues relating to sewage flow, blockages, pumping capacity, odour control, equipment failure, and system performance.
Coordinate testing, commissioning, and handover of sewage infrastructure.
Develop and monitor preventive maintenance requirements for installed sewage and wastewater equipment.

Stormwater Management and Drainage Infrastructure:

Coordinate the planning and implementation of stormwater management systems for residential estates and building developments.
Work with civil engineers and infrastructure consultants on stormwater collection, conveyance, pumping, and discharge arrangements.
Review stormwater management plans, drainage layouts, pump specifications, and associated technical documentation.
Supervise the installation of stormwater pumps, pumping stations, culverts, drainage-related mechanical equipment, and other associated systems where applicable.
Assess stormwater management challenges, including flooding risks, inadequate discharge capacity, water accumulation, and equipment limitations.
Support the implementation of sustainable stormwater solutions, including attenuation, retention, controlled discharge, and rainwater reuse where appropriate.
Coordinate inspection, testing, and commissioning of stormwater pumping and management systems.
Ensure installed systems operate effectively and are suitable for the development's site conditions and infrastructure requirements.

Mechanical Design Review and Technical Coordination:

Review mechanical drawings, technical specifications, equipment schedules, and installation details for sewage and stormwater systems.
Coordinate with civil and structural engineers on pipeline routes, gradients, manholes, pumping chambers, foundations, access requirements, and equipment locations.
Work with electrical engineers on pump power supplies, control panels, instrumentation, alarms, and automation systems.
Coordinate with architects, MEP consultants, quantity surveyors, and project managers to resolve design conflicts and ensure constructability.
Evaluate equipment selections, pump capacities, system requirements, and technical submissions.
Identify design inconsistencies and recommend practical, safe, and cost-effective engineering solutions.

Construction Supervision and Project Coordination:

Supervise contractors and subcontractors executing sewage, wastewater, and stormwater mechanical works.
Conduct regular site inspections to ensure compliance with approved drawings, specifications, quality standards, and project schedules.
Monitor installation quality, materials, equipment, workmanship, and construction progress.
Coordinate procurement requirements, equipment delivery, installation sequencing, and site activities.
Participate in project meetings, technical reviews, inspections, and progress assessments.
Prepare site reports, inspection records, technical assessments, and progress updates.
Identify project risks, delays, defects, and technical challenges and recommend corrective actions.
Support project delivery within approved budgets, timelines, safety requirements, and quality standards.

Testing, Commissioning, and Maintenance:

Develop and oversee inspection, testing, and commissioning procedures for sewage and stormwater mechanical systems.
Verify the operational performance of pumps, motors, control systems, valves, and associated equipment.
Ensure relevant functional tests and performance checks are completed before system handover.
Coordinate the preparation of operation and maintenance manuals, equipment records, as-built documentation, and handover reports.
Recommend preventive maintenance schedules and operational procedures to improve system reliability.
Provide technical support for troubleshooting and resolving operational issues after installation.

Environmental Compliance, Safety, and Quality Assurance:

Ensure sewage and wastewater systems are designed, installed, and operated in accordance with applicable environmental, public health, engineering, and safety requirements.
Coordinate with relevant consultants and authorities on wastewater treatment, discharge requirements, and environmental approvals.
Monitor construction quality and ensure appropriate inspection and testing procedures are followed.
Promote safe working practices during excavation-related activities, confined-space work, equipment installation, and commissioning.
Support measures that reduce environment
