What is one common issue that can arise due to inadequate drainage around a mound system?

Inadequate drainage around a mound system can lead to water accumulation, which is a significant issue for the functionality of the system. When water cannot adequately drain away, it can create a saturated environment that compromises the soil's ability to treat wastewater effectively. The accumulation of water can result in poor absorption and filtration of effluent, which ultimately can lead to system failure. This failure may manifest as surface water pooling, backup of wastewater, or the system being unable to function as designed.

This challenge underscores the importance of proper site evaluation and drainage design when installing mound systems to ensure that they operate efficiently without being overwhelmed by excess water.
