The Township of Tehkummah appealed under section 64 of the Drainage Act regarding the quality of construction of the Hierons Drain.
During construction, the engineer and contractor made unauthorized changes to the approved design, which resulted in flooding on an upstream property after an unusual rainstorm.
The Tribunal found that neither the engineer nor the contractor had the authority to alter the approved design without the Township's consent.
The Tribunal ordered remedial work to correct the unauthorized changes and directed the Township to bear the costs, as the engineer and contractor were acting as its servants.
