Project Value
The Clyde Creek Odour Control and Detention Storage project was to address the issues the existing sewerage pumping station was facing due to major population growth in the area. The pumping station was at significant risk in generating hydrogen sulphide and other odorants into the system, as well as low flows and long detention times combined with long rising mains. The combination of these factors proved a real odorant risk due to the proximity of surrounding homes.
To address these risks the following equipment was installed as part of the scope of works:
- 800,000L of detention storage across four buried tanks
- Foul air extraction and treatment odour control unit (OCU) including:
- Penetration to existing wet well
- Forced ventilation and vent stack
- 2-stage treatment process including bio-trickling filter and activated carbon filter
- Ferrous chloride chemical dosing unit (CDU) including:
- Chemical delivery bund and chemical storage
- Delivery pumps and pipework
- Electrical supply, switchboard and controls (modification of existing switchboards)
key challenges
- Development of a detailed design incorporating functional needs of the system and construction constraints of the location
- Working within tight confines of an existing housing development
- Maintaining a tidy, safe and productive site in an operating facility
- Ground conditions
Key innovations
Due to a restrictive footprint of the site and needing to provide continous access to overnight crews, the delivery and placement of pea gravel and crushed rock to backfill the detention tanks using mobile conveyors helped reduce backfilling time and allow crews to compact crushed rock efficiently and safely, reducing construction time and disruption to the public.
