You were in the septic installation business and it was your responsibility to make sure that the systems you installed were durable and really worth the money the customers paid. A septic system, in this case a sand mound system, is the waste water treatment facility of a household that has a high water table. It is the one that makes sure that the household members will be safe from pathogens and contaminants. The sand mound system helps assure that the house is inhabitable. Your son asked, How long do raised mounds last?
Sand mounds, like all septic system types, are made of various materials according to the customer’s budget range. The most common are concrete and steel sand mounds. Concrete can last a year up to 40 years. The lifespan depends on the mixture and quality of the concrete material. It is very porous and is very vulnerable to cracks that will definitely affect its performance and longevity. Steel sand mounds are said to last 15 to 20 years but by that time, they would already be so rusted. These would give out when a vehicle runs over them. Both concrete and steel sand mounds start deteriorating the moment they are installed. It would be better if you get them installed when the soil or the weather is dry. Polymer is the latest material that is said to be the most durable and long lasting among all three. It resists the acids and the salts that deteriorate concrete and steel easily. Just as long as its physical structure remains intact, it will be fine. It also promises decades of use.
Waste water has a lot of substances that will contribute to a sand mound’s degradation and malfunction. The concoction is often a result of various household solutions that the homeowners have used through the years. Most of them prefer antibacterial ones that really affect the internal environment of the sand mound. As you know, the sand mound must retain a good number of bacteria for the breakdown of the solid waste materials that enter the system. This is to prevent clogging and failure of the filter and soil absorption systems. These chemicals also affect the physical structure of the sand mound tank and components. The structures should endure the torture of the harsh solutions and attacks of the natural elements as well.
