Sewer system innovator, contractor form partnership

Innovative Water and Sewer Systems (IWSS) has signed a national partnership agreement with PCL, a leading Canadian general contracting company, for the construction of sewage and water infrastructure in communities across Canada. The agreement will make PCL the exclusive delivery contractor for the SBS(tm) wastewater management system patented by IWSS. As a result, the partners say communities and developers can now benefit from the environmental and cost advantages of the IWSS system, coupled with the expertise, scale and cost certainty of PCL's construction and project management services.

"The establishment of our national partnership agreement with PCL immediately strengthens IWSSI's ability to supply and service municipalities and developers across Canada," said Bruce Linton, president and CEO of IWSS.

Dwight Brown, vice-president and district manager for PCL, noted that "PCL operates a national special project team which will provide the bid and build expertise for all IWSS opportunities. Through this structure we will be well positioned to provide municipalities and developers fixed price solutions to their sewage and water requirements."

IWSSI designs and implements waste water management systems utilizing the SBS(tm) patented solid and liquid waste collection systems. For many communities the system can provide community sewer and water systems with superior performance at costs much lower than those of traditional methods. IWSSI systems have been in operation in Ontario communities since 1989 and are approved by the Ontario Ministry of Environment; they also meet the Ten-State Standard in the United States.

As an alternative to the traditional concrete pipe system, the SBS system uses an underground clarifier tank close to the sewage source (e.g. the house or plant) to separate the solids within minutes after they enter the system. The water passes through the clarifier, then through small flexible pipes to the treatment plant which receives only this water and is consequently much smaller, simpler and less costly. Solid wastes are kept separate by the clarifier, which is pumped every seven to ten years and the material sent to landfill for disposal (as is commonly done from large central plants).

The flexible pipe can be installed by boring and drawing the pipes through, eliminating the need to dig trenches to install the concrete system. The flexible pipe system does not leak (as concrete pipes tend to do at each connection), so water and sewer pipes can be laid side by side, whereas concrete pipe systems must be laid in separate trenches to prevent cross-contamination.

Another feature of the SBS system is that it does not absorb groundwater, as concrete systems do, so storms do not result in overflows and the system can be designed only for the quantity of material that will come from the serviced connections. By contrast, concrete systems must be designed for twice the anticipated flow from the service connections because groundwater seeps in, significantly increasing flow to the treatment plant.

Having developed the system, IWSS found that, as a small company, it lacked enough depth and credibility to take on important contracts with municipalities or developers. PCL's position as a major contractor will enable it to act as the contractor with the municipality or developer, offering a fixed price and full performance assurance.
