Developers

Clearford has researched, refined and patented the SBS™ system and developed it to meet the stringent requirements for North American settings, including design adaptations for weather and frost conditions.

Strategic partnering with PCL as a national constructor for Clearford will provide the confidence of a well designed and managed construction process, with substantive quality control and effective system warrantees and performance guarantees. 

The SBS™ solution has numerous benefits for developers, including:

• Approved by Building Code, Ontario Water Resources Act, and the Condominium
  Act, 1998
• Efficient use of services and land – design flexibility and scalability
• Dramatic project cost reductions, and no upfront fees
• Security of renowned National Construction Partner PCL for system warrantees
  and guarantees
• Environmentally superior wastewater collection
• No leakage of sewage into the environment
• Easy installation, operation and maintenance
• Tanks installed with house construction program – defers partial system ownership
  and cost to homeowner
• Minimizes construction waste with narrower trenches and less rock excavation required
• Can market environmental benefits to end client

Unparalleled Design Flexibility & Scalability

In historic gravity sewers, straight alignment in both horizontal and vertical planes are an essential part of the functionality of the sewer system, with maintenance holes required for every change in grading or horizontal directional change and at regular 100 metre intervals along the piping systems; these linear requirements are driven by the need to carry solids in the piping system.

The SBS™ clarifier tank removes solids from the waste stream at each household, so the piping system only carries liquid. As such, the SBS™ main piping system can be installed with curvilinear alignment, as well as variable grading within the overall main and lateral systems. With the SBS™, a subdivision can be designed based on either community requirements (personal preferences or constraints), or conforming to the natural contours and landscape, rather than being mandated by linear grid patterns. As well, horizontal directional drilling used with the SBS™ installation can preserve sensitive areas, such as aquatards and historic trees.

Treat What Needs to be Treated

For each 1,000 people connected to a historic gravity sewer, 32,000,000 litres of groundwater enter the sewage collection system each year, and become contaminated, then taken to a treatment plant. This is simply not a responsible approach to providing sanitary sewer servicing. The sealed SBS™ system guarantees zero groundwater contamination and no unnecessary treatment of clean groundwater – an environmentally and economically rational approach.

Process Solids More Efficiently

All sewage treatment processes generate solids. Some do it better than others. The SBS™ system processes solids by separating them right at their source – and allows them to digest in clarifier tanks for 7-10 years. Retaining the solids in the tank allows for natural digestion to take place (a methodology to reduce sludge volume), which ensures that the overall volume going to the treatment plant will be reduced by as much as 50%. Sewage treatment plants connected to a historic gravity sewer process all of the solids on a daily basis, and can only degrade the solids based on the storage capacity of the plant’s digester, which if offered at all, is generally limited to 60 days residence time. This means that the biosolids are then returned to the environment in greater volumes and on a more frequent basis.

Buyers Want to Go Green

There is a growing worldwide recognition of the benefits of environmental responsibility and while there are many factors that contribute to the purchase of a home, (location, price, amenities, etc.), it is considered a premium to be part of a development with identified green features. The Clearford Small Bore Sewer™ system is a win-win-win for the home owner, the developer, as well as the environment.
