Amendment and Renewal water licence: 3BM-SAN2025The Government of Nunavut, Department of Community and Government Services, on behalf of the Municipality of Sanikiluaq, is applying for the construction of the new wastewater treatment facility (WWTF) and amendment of the discharge effluent limits in the existing water license 3BM-SAN2025 to effectively service the growing population in Sanikiluaq over a 20-year life span. The facility consists of a lagoon and wetland-treatment-area and will be designed to meet the long-term needs of Sanikiluaq and the regulatory requirements. The lagoon requires a working volume of 122,401 m3 based on projected annual wastewater generation until 2047.The treatment goals for the WWTF effluent criteria at the end of treatment are established as 100, 120 and 1.25 mg/L for carbonaceous biochemical oxygen demand (CBOD), total suspended solids (TSS) and un-ionized ammonia as nitrogen, based on a 6-year research project completed by Centre for Water Resources Studies at Dalhousie University. The design consultant recommends that the effluent quality limits applied be CBOD 100 mg/L, 120 TSS mg/L, and to remove faecal coliforms as a parameter since this is a public health parameter and not an environmental parameter. The receiving environment is zoned for waste disposal and not used by the public for fishing, harvesting, or recreation. Faecal coliforms are not included in the federal Wastewater Systems Effluent Regulations SOR/2012-139 Fisheries Act Registration 2012-06-29. Faecal coliforms are also no longer applied as an environmental parameter in the Northwest Territories where the Nunavut Water Board historically derives its effluent parameter decisions on. Since new sewage lagoon will be designed for life span of 20 years, we are proposing license renewal year to be 2047.
