Project: Pomquet SBR


Pomquet SBR and Collection System
Municipality of the County of Antigonish -2002/2003

In 2002 C.J. MacLellan & Associates tendered over 4.5 kilometres of small diameter collection sewer (150mm diameter) and forcemain (75mm diameter) to service the Village of Pomquet. The project included individual pump chambers at those properties that required a pressure flow condition and cleanout chambers at others that flow by gravity to the local sewer.

One large  lift station on Taylors road pumps sewage up to the treatment plant confluence manhole, while another on Cove road receives gravity flow than forces sewage back along the gravity line up to the confluence manhole near the treatment plant.  An SBR treatment plant designed by ABL Environmental consists of one  EQ tank, two reactors and a digester cell with the necessary
components to discharge effluent to the Pomquet harbour via a 450 metre long 150 mm diameter outfall pipe ballasted on the harbour bottom.

The project considered a number of tenders simultaneously with work extending over a one year period at a cost of $1.5 million.

Overall the Municipality is very pleased with the treatment plant and its connecting infrastructure  and has on many occasions provided tours of the facility and system for municipal operators, NSEL staff and other interested parties in this technology.
