Description

This paper presents two case studies for the delivery of wastewater servicing solutions: one in Ontario, Canada and the other in Gujarat State, India. In each case a decentralized small diameter gravity sewer wastewater collection and treatment system was implemented for servicing residential development—with some interesting differences and similarities. The first case is a small private mobile home park in Eastern Ontario under a Ministry of Environment Order to address failing on-site septic systems. The Municipality was obliged to take over operation of the on-site systems; however, there were not adequate funds available to rectify the failing systems. A group of local companies initiated the process to find and deliver a solution featuring a Design-Build-Operate-Finance model for a private communal sewage system showcasing advanced wastewater technology. The second case is a rural Indian village without wastewater servicing infrastructure, but with considerable political incentive to implement a new low-maintenance communal sewage system funded through a government-regulated corporate social responsibility program. The completion of the project will enable this village to be cited as the first open defecation free village in Gujarat State; however, success will ultimately be measured by long-term user buy-in. Each case study will discuss the project context; implementation of design, approvals and construction; financial and delivery model; and key success factors and lessons learned. Both case studies will highlight how using unconventional technology and innovative funding enabled the implementation of decentralized wastewater solutions in each situation
