When a long-standing, local Ottawa pub proposed an expansion of their existing kitchen facility in 2009, the requirement of having the existing septic system assessed arose, and ultimately so did the beginning of a challenging project. The pub was serviced by an existing septic system that was installed as a replacement system in 1998, and had been designed for a peak daily sewage flow of 4,500 litres. The system consisted of a 9000 litre septic tank, a 2,700 litre grease interceptor, a pump chamber, and a fully raised Class 4 Filter Media leaching bed composed of two cells and an imported sand mantle. Houle Chevrier Engineering Ltd. (HCEL) had been retained by the developer to provide geotechnical consultation services as part of the kitchen expansion. Following the request by the local Chief Building Official (CBO) to have the existing septic system assessed, HCEL was retained to provide this additional service. The assessment included a review of available documentation, a physical assessment of the system, sampling and analysis of the wastewater being generated at the facility, and the implementation of water usage monitoring. An inspection of the existing system found the leaching bed to be displaying signs of distress, including an elevated effluent level and “biomat” accumulation within the filter media. Following a short period of water usage monitoring, it was estimated that the average daily and peak sewage flows were 4,000 litres and 7,500 litres, respectively, which represented an increase from the design flow that was based on monitoring data gathered in 1998. The results of two initial rounds of wastewater sampling and analysis determined elevated concentrations of a BOD (±1,300 mg/L); total suspended solids (TSS) (± 150 mg/L); and fat, oil and grease (FOG) (± 70 mg/L). continued on page 10 …
