Effect of Soil Type on a Mound System’s Longevity
The longevity of a mound system can be greatly affected by the soil type in which it is installed. The soil makeup plays a significant role in determining the success or failure of the drain field system. There are different types of soils that are usually classified as either coarse-grained or fine-grained soils. Coarse-grained soils include sand and gravel, while fine-grained soils include silt and clay.
- Sand: If the soil is sandy, it will drain water very quickly. This could make the mound system’s drainage less effective, which could cause it to fail earlier. The sand particles also tend to increase the amount of aerobic bacteria present in the system, which can lead to a faster breakdown of the effluent.
- Clay: If the soil is clayey, the opposite will be the case. The soil will drain slowly, which could cause the effluent to saturate the soil and lead to a more rapid failure of the system. The clay soil is also more likely to compact under the weight of the drainage and lead to the formation of a hard pan. This could cause the effluent to pool and prevent it from being absorbed into the soil.
- Silt: Silt is somewhere in between sand and clay. It is less porous than sand but more porous than clay. As a result, silt soils will retain some water for a short period, but they will not saturate as quickly as clay soils. A mound system built on silty soil tends to last longer than one built on clay soil, but not as long as one on sandy soil.
Therefore, it is essential to conduct a soil analysis and seek expert advice from professionals on the best type of mound system suitable for the soil type in your area. Proper design and installation of a mound system are key factors that will determine its longevity regardless of the soil type. Conducting regular maintenance such as pumping the septic tank and avoiding harsh chemicals can also prolong the life of the system.
| Soil Type | Pros | Cons |
|---|---|---|
| Sand | Drains water quickly | Drainage is less effective; effluent breaks down faster due to presence of aerobic bacteria |
| Clay | Drains slowly | Effluent saturates soil, system fails more quickly; soil compacts, forming hard pan and preventing proper absorption |
| Silt | Retains some water for short period; system lasts longer than on clay but not as long as on sand |
Overall, the soil type has a significant impact on the longevity of a mound system. Proper design, installation, and maintenance are essential in ensuring the system operates efficiently regardless of the soil type.
