I think the recent construction activity near Victoria street is part of the Greater Moncton sewer system upgrade. I found this article online, but it dates back to october 2010:
Moncton plans for $126 million sewage system
Moncton, Riverview and Dieppe are among the fastest growing areas in New Brunswick and that has increased the demand on the city’s sewage line.
But a $126 million plan developed by the Greater Moncton Sewerage Commission includes the construction of a new treatment plant that will exceed federal guidelines.
A new sewage line, pumping stations, screening facilities and a tunnel under the Petitcodiac River are also part of the plan.
The first step is to build the tunnel, Commission Chairman Ronald LeBlanc told The Times Transcript.
A new sewage line running through the tunnel will connect with a pumping station that will be erected in Dieppe near Victoria Avenue.
The newspaper said the plan designates close to $38 million for pumping stations, an outfall and screening facilities. Almost $6 million has been budgeted to complete the solid-waste facility lo- cated on Delong Drive.
Its balance sheet also includes $11 million for pre-treatment and improved solid screening, and $7 million to upgrade sewage and storm runoff separation.
A biological treatment facility that uses advanced technology and two new clarifiers will cost $49 million.
LeBlanc told the paper when the system is in place the sewage released into the Petitcodiac would be close to the tertiary level.
The commission would like the project to be financed between the provincial and federal govern- ments and the city. If that isn’t realized LeBlanc said it might be forced to triple its $150/year sewage bills.
Public information sessions about the plan were being scheduled for October in Riverview, Moncton and Dieppe.
