Sanitation Market estimated at $152 Billion between 2007-2020 – The World Bank
Define a sustainable outcome and let the world respond.
Asia, Africa and Latin America must implement, as a part of their initial stabilization, a truly sustainable infrastructure that is scalable to the increasing demand it will see. If addressed properly, by leveraging systems such as the Clearford Small Bore Sewer™, these developing countries have the opportunity to leapfrog the existing developed regions of the world and flourish as nations in the decades to come.
Market Overview
The global sanitation market is estimated by The World Bank to be worth approximately $152 billion between 2007 and 2020. As the world continues to realize the massive challenges that lay ahead related to access to clean water, the effective management of wastewater will become increasingly important. With Clearford’s innovative wastewater collection system, many governments and private developers around the world, have already taken notice, and realized the advantage that Clearford offers them.

Effluent reclamation infrastructure is an area where Clearford has developed significant expertise and industry leadership. We recognize the importance of an effective system as a critical step in water conservation and have the experience to help clients develop practical and innovative solutions that best meet their environmental control needs, from process design to construction and commissioning.
The projects summarized below provide a general overview of Clearford’s depth in sewerage systems and effluent treatment. This broad base of expertise is based on experience gained through designing and building complex systems for over 20 years.
Wardsville, Ontario
Clearford’s Small Bore Sewer™ (SBS™) provided an economical, operational and environmentally superior solution to Wardsville’s wastewater dilemma. Wardsville is a community in southwestern Ontario comprised of both homes and businesses, a large nursing home and a golf course. For several decades Wardsville had been experiencing the progressive failure of its communal and private sewage systems. Raw sewage was surfacing in the community and was contaminating local wells and storm water drainage basins that eventually discharged untreated sewage into the Thames River and other surrounding creeks. In 1999, after considerable research, Wardsville’s Municipal Council selected Clearford’s SBS™ wastewater collection system over a traditional “big pipe” gravity sewer.
Highlights of the Wardsville SBS™ Installation:
- Using horizontal directional drilling (HDD) technology, the project was installed in eight months with no road closures and no detours, this was ½ the time taken by the traditional system;
- The SBS™ system was connected directly to the buildings’ existing sanitary drains, significantly reducing onsite plumbing costs to the homeowner. Homes did not require expensive internal re-plumbing to a “big pipe” system.
The Wardsville SBS™ installation and its successful performance demonstrate that Clearford’s solution is cost effective, environmentally sound, and works as designed after over 12 years of operation.
Village of Field, Ontario
Pilot Project, 1989
In response to the quagmire of widespread septic systems failures that polluted local aquifers and wells, the Ontario Ministry of the Environment (MOE) organized a research competition to seek out a new methodology to transfer sewage to a centralized plant which would remove the dependence on private, onsite systems that were harming rural water resources. The finalist selected was, what is now known as, the Clearford Small Bore Sewer™ system for the pilot project in Field, Ontario in 1989. A northern community near the 49th parallel, Field contains approximately 40 homes and businesses which were connected to this cluster system technology. The collection system was designed according to the same parameters and methodology as those outlined in Alternative Wastewater Collection Systems and followed the recommendation to use thermally fused joints to provide watertight piping.
When completed, only the sum of the total effluent volumes leaving each home were received gradually throughout the day at the extended aeration treatment plant, which provided for a smaller plant footprint; plant size was modified to accept lower peak flows, decreasing the overall size of the plant’s equalization tanks and eliminating headworks. Flow attenuation and inflow/infiltration prevention allowed for a more economical treatment plant to be sized by designers for this community.
The pilot project collection system was constructed in less than three months and cost 56% less than the estimated historic gravity sewer. The monitored effluent generation at the treatment plant was 2,380 gallons per day [9,000 L/d] or, if 2.0 persons per connection is assumed, 34 gal/capita/day [129 L/capita/d]. The treatment plant had flows of 6,870 gal/d [26,000 L/d], indicating that that sealed sanitary collection sewer prevents 4,490 gal/d [17,000 L/d] of groundwater from entering the piping, mixing with raw sewage and flowing to the treatment plant, only to be processed at a greater cost and decreased treatment efficiency.
Highlights of the Field, Ontario Pilot Project Installation:
- A warm & modern village located in Northeastern Ontario
- 1989 installation
- Design capacity of 40 single family homes & municipal buildings
- Vessels capacity: 2.7 and 4.6-m3
- 75-mm Ø HDPE piping – (3) pumping stations – 1.1 m piping burial depth
- Actual sewage flow: 130 L/c.d (reduction from 990 L/c.d after I&I elimination)
Innovista Eco-Park
Innovista Eco-Park is the largest Greenfield Eco-Industrial Park in Canada. Located in Hinton, Alberta, the park covers a total area of 44ha and has been developed in three phases: (I) 13.5 ha, (II) 6.0 ha and (III) 5.5 ha. The concept of the Eco-Park was developed by Eco-Industrial Solutions Ltd., one of North America’s leading eco-industrial planning and development consultants. Their approach to the Innovista Eco-Park not only reflected their experience, but lessons learned from their global network of eco-industrial and sustainable infrastructure specialists. They have experience working in Canada, as well as China, Korea, Mexico, Peru, Ecuador and Egypt.
Their planning and design work for eco-industrial parks include making sure that all the infrastructure – roads, water, sewer, stormwater and energy – is sustainable. It was in this capacity that they discovered the Clearford SBS™ system.
Highlights of the Innovista Eco-Park Installation:
- 12-month completion (open trench technology)
- $ 7.4 M capital cost vs. $ 12.6 M for a historic gravity sewer
- Modular design for future expansions
- Design capacity of 6,500 people
- Clarigester™ tanks: (246) 3-m3 individual units + (62) 9-m3 communal units
- Collection system: 26 km long, 75-mm + 100-mm + 150-mm diameter HDPE piping
Loon Lake Resort
Loon Lake Resort is a 164 unit condo corporation and resort community resting on 375 acres near Madoc, Ontario. By 2006, many of the existing septic systems were failing, threatening to contaminate the small onsite spring-fed lake. The poor state of the existing infrastructure was of significant concern to the Ministry of the Environment of Ontario and restricted the corporation’s plans to grow and expand the park. Additionally, Loon Lake also had a fixed and limited budget with which to undertake the improvements to their water and wastewater systems. After considerable research, the owners of Loon Lake Resort selected Clearford’s SBS™ wastewater collection system instead of a traditional “big pipe” gravity sewer. Clearford was awarded a contract to design, supply and install the complete SBS™ system, including installation of the Bergmann wastewater treatment system and disposal field (design by Jagger-Hims Ltd.).
Highlights for the Loon Lake Resort installation:
- The capital cost of the turnkey installation was 50% of the capital cost for installation compared to a traditional gravity sewer system, wastewater treatment and disposal;
- The project was delivered under a fixed price contract for collection and treatment;
- Using open trench construction, the project was installed in four (4) months over the Fall and Winter, minimizing the impact on the park’s operations as well as existing structures, trees and other landmarks;
- Additional system connection points were installed with ease during construction to facilitate future park expansion;
- Access points for system maintenance were installed off road, limiting potential damage as a result of winter ploughing or loading from trucks and trailers;
- Operating costs are approximately 50% less than the estimates for a traditional gravity sewer;
