ABSTRACT: The use of lagoons is one of the most cost-effective wastewater treatment (WWT) options for rural communities in Canada. This type of wastewater treatment is also used at several military bases of the Canadian Armed Forces. Lagoons are low-maintenance systems that use natural and energy-efficient processes. This paper presents a monitoring programme that will be used to conduct an investigation of a two stage aerobic lagoon system, at a military base in Central Canada, originally constructed in 1988. The proposed programme includes the use of in-situ instrumentation for the analysis of parameters indicative of treatment performance and sampling for detailed analysis of wastewater characteristics. It also ariety of methods including a LiDAR survey. The proposed monitoring programme should allow a quantitative assessment of the WWT lagoon with the view of .

RÉSUMÉ: tion de lagunes est parmi les méthodes les moins dispendieuses pour le traitement des eaux usées pour les communautés rurales au Canada. Ce type de traitement des eaux usées est aussi employé à plusieurs bases militaires des Forces armées canadiennes. Les lagunes utilisent des processus naturel, écoénergétique et ainsi nécessite peux aérobic utilisé a une base militaire situé dans la région central du Canada, originalement construis en 1988. Le programme -mettre une évaluation quantitative de la lagune dans le but de base.
