Programme overview
Introduction:
Wastewater collection network O&M covering sewer CCTV, lift stations, H2S and blockage control is a 5-day course for managers and engineers who run gravity sewers, rising mains and pumping stations, ending with a Collection Network O&M Plan for a case utility. Networks that are cleaned only after complaints suffer repeat chokes, spills from manholes, crown corrosion and odour near homes. Nominees already supervise crews, jetting units or pump stations and work through inspection walkthroughs of CCTV footage, wet well layouts and spill records. CoreConcept Training Center delivers this wastewater collection network O&M course.
Course Objectives:
- Assess gravity sewer and manhole condition from CCTV footage, PACP defect codes, sonar profiles and manhole survey sheets to set inspection frequencies
- Plan risk-based cleaning cycles with jetting, combination units, root cutting and debris removal tied to blockage hot spots
- Operate and maintain lift stations, wet wells, submersible pumps, level controls and telemetry alarms to cut pump trips and overflow events
- Control hydrogen sulphide generation, crown corrosion and odour in rising mains and gravity sewers using monitoring data and dosing options
- Run a fats, oil and grease source control scheme with grease interceptor inspection, food outlet permits and public awareness
- Prepare a Collection Network O&M Plan with spill response, infiltration and inflow reduction targets and network KPIs for a case utility
Target Audience:
- Managers responsible for the operation and maintenance budget of municipal sewer networks
- Engineers responsible for sewer inspection, cleaning schedules and blockage reduction
- Supervisors responsible for lift station crews, standby pumps and telemetry alarm response
- Specialists responsible for odour complaints, hydrogen sulphide monitoring and corrosion of sewer assets
- Officers responsible for trade effluent and grease interceptor control at commercial premises

- Network Performance Reporting
Why Attend This Course:
- Deliver a Collection Network O&M Plan to the head of wastewater operations for approval and budgeting
- Decide which sewers to inspect, clean or escalate for repair using defect scores and blockage history
- Avoid repeat chokes, manhole spills, pump burnouts and odour complaints that draw fines and public criticism
- Coach jetting crews, pump station technicians and grease inspectors with the checklists and hot spot maps
Conclusion:
Back at work, the participant presents the Collection Network O&M Plan to the head of wastewater operations and the asset management team. Management uses it to fix inspection frequencies, assign cleaning crews to hot spots, set lift station maintenance routines, choose sulphide dosing points and agree spill response duties. After the first six months under the plan, the utility should compare spills, chokes, pump trips and odour complaints with the KPI targets and adjust the cleaning cycles and dosing that have not delivered.
Frequently Asked Questions (FAQ):
What should participants know before a wastewater collection network O&M course?
Participants should already supervise sewer crews, pump stations or network planning and be able to read a network map and a pump data sheet. Bringing anonymised spill records, CCTV clips or lift station alarm logs from their own utility helps during the walkthrough day.
How does wastewater collection network O&M differ from a sewage treatment or pipe rehabilitation course?
This course covers keeping sewers and lift stations flowing day to day: inspection, cleaning, pumping, odour, grease and spill control. Treatment courses focus on biological processes inside the works, and rehabilitation courses focus on designing and installing liners or replacement pipes.
Why does hydrogen sulphide matter in wastewater collection network O&M?
Hydrogen sulphide forms when sewage turns septic in rising mains and slow sewers. It causes rotten-egg odour complaints, converts to acid that corrodes concrete crowns and manholes, and is a deadly gas hazard for crews entering wet wells and chambers.
What do participants take back from the wastewater collection network O&M course?
Participants take back a Collection Network O&M Plan with an inspection frequency matrix, a hot spot cleaning schedule, lift station routines, a sulphide control plan, a grease control scheme, a spill response card and a KPI set they can adapt to their own utility.
