Problems sometimes occur. The following list may help narrow down the cause of the problem:
- Lagoon depth falls below 2-foot minimum due to:
- Leak in artificial liner
- Clogged inlet pipe
- Low flow rate into lagoon
- Holes in dike from plant roots or burrowing animals
- Not enough clay in natural soil liner or not compacted
- Lagoon flows over the dike and banks. This may be caused by:
- Improper sizing
- Excessive water use
- Heavy precipitation
- Surface water from site is draining into lagoon
- Lagoon has persistent odor. This may be due to:
- Algae bloom blocking sunlight
- Anaerobic conditions
- Improper sizing and /or overloading
- Insufficient air flow-blocked by trees, shrubs, or other vegetation
- Lagoon has high numbers of flies and mosquitoes:
- Long grass and weeds may be blocking the wind and providing breeding areas for flies, mosquitoes, and other insects.
