Design & Engineering

At CEI Services, our in-house Design and Engineering team specialises in tailored solutions for the water and wastewater sector, combining deep industry knowledge with hands-on experience across treatment plants, pump stations, and distribution systems.

Engineering Expertise

  • Power Distribution
– Comprehensive low-voltage and general power layouts designed for operational safety, energy efficiency, and expandability. This includes detailed load assessments, protection studies, and fault level calculations.

  • Fully Designed Treatment Plants
– Complete electrical and control designs for water and wastewater treatment facilities—including motor control centers (MCCs), control panels, PLC and SCADA layouts, and process instrumentation integration.

  • Pipeline Pump Stations
– Power and control designs for pump stations—delivered with full hydraulic/electrical coordination, motor starting schemes, surge protection, telemetry, and remote access capability.

We use AutoCAD Electrical to generate precise and clearly documented:

  • Switchgear assembly drawings
  • Single-line diagrams
  • Control schematics
  • Cable schedules
  • Field installation layouts
  • Terminations and I/O wiring diagrams

Advanced Technologies

Our engineering incorporates the latest technologies for motor control and process integration via:

Programmable Logic Controllers (PLC)

Operator Interface Panels (OIP)

Remote Telemetry Units (RTU)

SCADA Communications

Compliance & Standards

At CEI Services, compliance is embedded in our engineering culture. Our team includes certified and experienced electrical engineers who ensure all designs and installations are delivered in full alignment with applicable Australian Standards, statutory requirements, and industry best practices.

We work to meet and exceed the following standards and codes:

  • AS/NZS 61439 – Low-voltage switchgear and control gear assemblies
This standard ensures switchboards are designed and tested for safety and performance. We follow it closely to deliver durable and compliant switchgear assemblies.

  • AS/NZS 3000 – Wiring Rules
These rules guide safe electrical system design and installation. Our team applies them to protect people and equipment from electrical hazards.

  • AS/NZS 3008 – Cable selection
Proper cable sizing is essential for efficient operation. We select cables based on current capacity, voltage drop, and installation conditions to ensure system reliability.

  • Australian Building Code of Practice
– We ensure our electrical work aligns with building regulations, supporting overall construction safety and compliance.

Features & Inclusions

  • Compliance with Supply Authority Service and Installation Rules.

  • Harmonic filters to mitigate distortion.

  • Detailed PLC I/O schedules.

  • Battery-backed 24VDC power supplies for control system resilience and fail-safe operation.

  • Generator sizing and interface design.

  • Detailed equipment engineering, matched to client-supplied materials or preferred equipment lists.

  • Integration of Solar PV Systems.

  • Design and integration of SAPS (Stand-Alone Power Systems) for remote or off-grid applications.

Commissioning & Client Support

We believe that commissioning and handover are not afterthoughts—they are critical success phases that define project quality and long-term operability. CEI provides detailed pre-commissioning, FAT (Factory Acceptance Testing), and SAT (Site Acceptance Testing) processes tailored to each project.

Our experienced commissioning team ensures:

  • System validation and compliance with design intent
  • Live testing under real-world conditions
  • Operator training, documentation, and full handover packages
  • Integration with existing systems and long-term maintainability

Our goal is to leave clients with a fully operational, safe, and documented system, ready for immediate and confident use.
