Operation and Maintenance
Overview
The most frequently cited maintenance concern for filters is surface and under-drain clogging caused by organic matter, fine silts, hydrocarbons, and algal matter. Common operational problems include:
- Standing water
- Clogged filter surface
- Clogged, inlet, outlet or under-drains
Design Phase Maintenance Considerations
Implicit in the design guidance in the previous sections is the fact that many design elements of filtering systems can minimize the maintenance burden and maintain pollutant removal efficiency. Key examples include: limiting drainage area, providing easy site access (REQUIRED), and providing adequate pre-treatment (REQUIRED).
