Re: Annual Reporting as per C of A#7337-66YQL4.
Dear: Mr. Orphan
The following is a summary of the year 2005 operations for the Port Burwell Wastewater
Treatment Plant, in accordance with the conditions set out in section#10 (6) of C of A
#7337-66YQL4.
Section
a. The attached spreadsheet entitled Annual Compliance Summary captures the
monthly treatment performance of the wastewater treatment plant along with
compliance and objective criteria met.
b. There were no significant operational problems encountered in 2005.
c. All equipment was maintained on a routine basis, following manufactures
recommendations and or past operating history. These records are available at
the wastewater treatment plant for review at any time.
d. Daily in house lab work and visual inspections of the treatment process are the
tools used to make adjustments for continued effluent quality.
e. Flow metering equipment is calibrated on an annual basis by R & R
Instrumentation. The calibration report is available at the wastewater
treatment plant for review at any time. The in house lab equipment is
calibrated on a regular basis by operations staff.
f. See attached spreadsheet for the effluent objectives that were met during the
2005 reporting period.
g. Sludge is hauled to land under C of A#S-0513-41. A total of 1201.25 m3 was
hauled to a total useable area of 19.4 hectares located at Conc.2 South part lot
11 & 12 in the Municipality of Bayham forming part of Elgin County. Sludge
records are available for review at the wastewater treatment plant.
h. Complaints received during 2005 were specific to odour in the wastewater
collection system. Wastewater is pumped from various serviced areas via
pump stations and force mains. Odour accumulates in the force mains due to
the size, length and low flow of some of the serviced areas. As oxygen
depletes in the force mains sulphides increase causing the said odours. A
sulphide reducing chemical known as Bioxide is being injected into the
system at various locations in the collection system which has proven to
successfully reduce odour complaints.
i. On October 27, 2005 , the spills action centre was notified that wastewater
had spilled from a forcemain chamber located at pump station#6 ( 54 Front
St. Vienna) due to a broken pipe . SAC issued incident#8174-6HKLBB. The
damaged pipe was repaired and the appropriate site cleanup was completed
during the said date.
Please do not hesitate to call me with any question or concerns at 519-874-4761.
Sincerely,
Ed Roloson
Water/Wastewater Superintendent
