Inexpensive lining system extends life of leaking tank

摘要

In 2001, during a routine tank inspection, the staff at Aylmer, Ontario, wastewater treatment plant noticed some fine cracks in the exterior of the fibreglass-rein-forced plastic tank (FRP) used to contain liquid alum. A meeting was held with members of council from the Township of Malahide, Wayne Simpson, project coordinator with the Ontario Clean Water Agency and Kentain Products Ltd. to solve the leaking FRP tank problems. This is a vital part of the Aylmer wastewater treatment plant's operation. An inspection of the tank was completed prior to the meeting and the conclusion was that the tank was still structurally sound.
