Lethbridge County Mitigates Wastewater Lagoon Risks Efficiently

Client's challenges: The county manages several wastewater lagoons which all require accurate assessment to determine if maintenance work is required. If work is required, the county faces the challenge of accurate budgeting and planning amongst balancing budgets.

Hydrasurvey's solution: To assess each wastewater lagoon and address the above priorities Lethbridge County contracted Hydrasurvey to complete a Lagoon Management Strategy.

• As a part of this strategy Hydrasurvey completed Lagoon Sludge Surveys at each lagoon. Each survey consisted of key metrics used to determine the priority level of maintenance required at each lagoon.

• These key metrics included, sludge volume and dry tonnes, effluent storage capacity, dredgeable sludge quantities, disposal suitability and qualitative observation.

• The Lagoon Management Strategy provided Lethbridge County with a clear plan to prioritize improvement and sustainability projects for their wastewater management practices. It also highlighted their commitment to proactive monitoring and ongoing maintenance projects.
