| DESCRIPTION: The bursting of Anaerobic
Sludge Digester No.3 at a 596,000,000 m3/d municipal sewage treatment
plant serving the City of Vancouver led to the necessity of discharging
incompletely treated and odourous sludge from that and other
digesters to sludge lagoons creating odour problems that had
to be mitigated. In addition, it became necessary to subsequently
truck undigested sludge to other treatment plants for processing.
This led to a multi million dollar insurance claim for the costs
of dealing with the results of the loss of the digester. NovaTec
was retained to conduct a forensic investigation regarding the
technical validity of the claim and concluded that the claim
was technically without merit. The findings were accepted by
all parties. |
