Many wastewater and water system components can be rehabilitated rather than replaced. Recently BMROSS’ Water and Wastewater Group staff have been involved in the assessment and rehabilitation of sewage pumping stations for several clients.

As part of sewage treatment plant upgrades in the Municipality of Bluewater, the main sewage pumping stations in the communities of Hensall and Zurich were assessed. The existing control buildings and wet wells were maintained, while sewage pump, process piping, standby generators, instrumentation and controls were replaced.

In Strathroy-Caradoc, a steel pre-fabricated pumping station installed in the 1980’s was sandblasted and re-coated in-situ to extend its useful life. The job was so successful a second, similar station, was completed using a similar process. Pump replacement and miscellaneous upgrades are being planned for two other stations.

For the Municipality of Lambton Shores, BMROSS completed inspections of nine sewage pumping stations in four communities. The inspections considered the concrete structures, metal railings, platforms and ladders and process piping and valves. At this time, several stations have had rehabilitation completed, with design related to additional stations underway.

St. Clair Township owns and operates over 30 sewage pumping stations. BMROSS is currently assisting the Township with design, approvals, and preparation of contract documents for rehabilitation work at five stations, with the range of work including pump, railing and platform, process piping, and control equipment replacement, as needed.

BMROSS staff have confined space awareness training and extensive concrete rehabilitation experience. The firm has relationships with electrical, coating, equipment and control specialists to assist in developing cost estimates and rehabilitation designs.
