Treatment plant.
Dear: Sir/Madam
The following is a summary of the year 2017 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. It can be noted that all compliance
criteria was met for the reporting period.
b. There were no significant operational problems encountered in 2017.
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. Increased and
consistent lab work by operations staff will ensure optimum plant
performance, and minimize environmental impacts.
e. Flow-metering equipment is calibrated on an annual basis. The calibration
reports are 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
2017 reporting period. Increased process control by way of operator
monitoring will ensure that objectives are consistently being met. Proper
mixed liquor solids, temperatures, and dissolved oxygen monitoring ensure
the nitrification process.

and a total of 610.5m3 was fall applied. There are no anticipated increases in
volumes for 2018. Records are available for review at the wastewater

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 while reducing collection system corrosion. Staff
continue to monitor odour along the forcemain throughout the year.
i. There was one spill event as a result of a directional drilling contractor hitting
the wastewater force main on November 22, 2017, located across from 55451

effects to adjacent properties as the spill and work area was confined to the
municipal road allowance. November 23, 2017 - SAC notification of spill
with approximately 15m3 of waste material removed from the work site by
use of a vac truck – SAC issued incident #8857-ATDJSW – information
