Re: Annual Reporting as per C of A#6348—7QAJBF for the Port Burwell Wastewater
Treatment plant.
Dear: Madam Neary
The following is a summary of the year 2009 operations for the Port Burwell Wastewater
Treatment Plant, owned and operated by the Municipality of Bayham in accordance with
the conditions set out in section#10 (6) of the above said C of A
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 2009.
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. HTC Instrumentation calibrates flow-metering equipment on an annual basis.
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
2009 reporting period.
g. Biosolids are hauled to land under the organic conditional site#S-0506-30 and
S-0513-41. A total of 1254 m3 was hauled in the spring and fall to a total
useable area of 87 acres. Records are available for review at the wastewater
treatment plant.
h. 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. There was one spill reported during 2009 ( incident# 0081-7S9NY). A
contractor damaged a four-inch forcemain during excavation of an Elgin
County bridge project. The damage resulted in wastewater entering the Little
Otter Creek. Upstream and downstream samples were collected from the said
creek as recommended by MOE staff.
Please do not hesitate to call me with any question or concerns at 519-874-4761.
Sincerely,
Ed Roloson
Water/Wastewater Superintendent
