Blocked or ageing sewer infrastructure is a growing concern for local councils across infrastructure, utilities, and construction sectors. Poor visibility into asset condition often leads to reactive maintenance, compliance breaches, and costly project delays—putting public safety, budgets and reputations at risk. Whether it’s unplanned downtime, inaccurate asset condition data, costly emergency repairs, or environmental compliance breaches—poor visibility into underground assets can derail budgets and timelines.
CSA Specialised Services tackles these challenges head-on with a streamlined, end-to-end solution for sewer network inspection and cleaning. In industrial or municipal maintenance, CSA’s drain cleaning services typically include sewer network maintenance, stormwater system flushing, gross pollutant trap (GPT) cleaning, and pipe relining or root cutting to ensure reliable infrastructure performance and regulatory compliance.
Phase 1: Project Planning & Mobilisation
CSA’s planning begins with pre-commencement activities to ensure risk mitigation, efficiency, and compliance:
- Site Assessments & Pre-Surveys: Accessibility, infrastructure conditions, and environmental risks are evaluated.
- Client Liaison: CSA works directly with councils and stakeholders to confirm project scope, timelines, and site access.
- Team Briefings: Pre-start safety meetings include Safe Work Method Statement review and hazard identification.
- Personnel Qualifications:
- CSA Induction & VOC Assessments
- Drain Cleaning System
- Inspect Sewer or Stormwater Assets
- Confined Space Entry & Gas Monitoring
- Equipment Prep: Vehicles are loaded with non-potable water and undergo full pre-start inspections.
Phase 2: Execution & Quality Control
CSA combines high-pressure jetting, vacuum extraction, and CCTV inspection for accurate, efficient, and safe sewer network cleaning:
- CCTV Inspection （If requested）:
- Pan-tilt-zoom cameras comply with CSA HSEQ protocols for condition assessment
- 360° imaging of manholes and defect-focused video capture
- Real-time video annotation: pipe material, defects, grade, asset ID, distance markers
- Data Reporting （If requested）:
- Footage logged using WinCAN VX
- GIS-compatible reporting ensures alignment with council asset systems
- Site Setup:
- Equipment positioned for minimal disruption to traffic and community
- Overhead clearance checks (3m minimum from power lines)

Phase 3: Handover & Post-Completion Review
CSA ensures each project is thoroughly documented, reviewed, and signed off by stakeholders:
- Deliverables:
- Digital CCTV files (mpg) on portable SSD
- WinCAN and condition assessment reports in council-approved formats
- GIS database files and GPS-logged data
- Final Checks:
- Post-clean inspections to verify scope completion
- Client review and formal sign-off
