The Small Bore Sewer ™ (SBS™) is a watertight small diameter wastewater collection system that provides servicing with superior operational and environmental performance at a significantly lower cost as compared to historic gravity sewers.
Clearford’s patented effluent sewer systems have successfully been in operation throughout North American communities since 1989, and all of these SBS™ serviced communities are positive references.
The SBS™ system has been reviewed and endorsed by the World Bank and the IFC.
Key among its unique and value-added features, the SBS™ system:
- Operates effectively in various climate and water flow conditions, and is an ideal servicing option for challenging installations in communities with extremely low daily water usage rates and/or low sewage generation flows;
- Produces an effluent quality which enables treatment to a potable standard;
- Eliminates groundwater infiltration and inflow, and prevents aquifer contamination by ex-filtration, due to the thermally sealed materials stipulated in the system design;
- Is installed at shallow depths allowing for a reduced need for heavy equipment, less disruption to the community and its existing infrastructure, and the ability to employ local labour;
- Has been designed to convert waste solids to an alternative fuel source, biogas (methane), resulting in a reduction in the overall volume of sludge to be treated and elimination of the requirement for solids delivery, handling and disposal;
- Allows for captured biogas (methane) to be used to generate electricity; thereby reducing greenhouse gas emissions by eliminating the discharge of biogas (methane) into the environment;
With the SBS™ as the enabling foundation technology, Clearford delivers, on a global basis, turnkey, fixed-price wastewater collection, treatment, and energy generation solutions.

"...a sanitation system has to be not only economically viable, socially acceptable, and technically and institutionally appropriate, it should also protect the environment and the natural resources."
Sustainable Sanitation Alliance, Fact Sheet on "Sustainable
Sanitation & Groundwater Protection" August 2009
SBS™ Operational Benefits
- Patented digestion process effectively eliminates bio-solids
- Primary treatment at source results in high quality effluent, consistent flows, and consistent and lower costs at treatment plant
- HDPE piping is lower in cost and has a design life of over 90 years
- No scheduled pipe system maintenance for the life of the system
SBS™ Environmental Benefits
- 21x reduction of greenhouse gases through methane capture when compared to equivalent carbon dioxide gas impact
- Conveyance of methane for reuse in electricity generation
- Sealed system means zero groundwater infiltration and zero sewage seepage
SBS™ Construction Benefits
- Overall system is flexible, modular and adaptable
- Shallow gradient piping installations eliminate need for heavy equipment – local manpower and hand tools can be used for trenching
- Piping is not sensitive to curvilinear alignment, inflective gradients or sharp slope changes
