How often should sedimentation basins with mechanical sludge removal equipment be drained and inspected?

• A. Once a month
• B. Once a year
• C. Once every two years
• D. Once every six months

Answer: (B)

Sedimentation basins equipped with mechanical sludge removal systems are critical components in water treatment facilities, as they allow for the separation of solids from water through gravity. Regular maintenance and inspection of these basins are essential to ensure optimal performance and to prevent operational issues. Draining and inspecting these basins once a year is a common industry standard. This frequency allows for thorough evaluations of the mechanical components and the sludge accumulation, enabling operators to assess the effectiveness of the sludge removal system. Inspections can identify wear or damage to equipment that may not be visible during regular operations. It also provides an opportunity to clean the basin if necessary, which helps maintain water quality and treatment efficiency. Choosing a timeframe such as monthly or bi-annual inspections may not be practical or necessary, as they could lead to unnecessary downtime or resource allocation that does not significantly improve overall maintenance outcomes. By adhering to an annual inspection schedule, treatment facilities can balance the demands of operational efficiency with the need for thorough equipment evaluation and maintenance.
