"Superior Excavations Solutions (Brendon) did an excellent job on my brother's anaerobic sewer system! My brother is a disabled veteran so I manage his affairs from New Mexico which can be challenging at times. But Brendon made it easy. He was working against severe rainy weather on a weekend to get this system in and get it up and running. My brother now has a new system and it is working like a charm.. I would highly recommend Brendon to put in any sewer system. "

Septic Tanks questions, answered by experts

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Oversized well pressure tanks are not always a bad thing, but it is still better to opt for a tank sized more appropriately for your well to save money and space. The advantage of an oversized well pressure tank is that it can reduce frequent pump cycling to conserve energy.

Adding a thin layer of dirt over a septic drain field is fine, especially if soil erosion has occurred. However, adding too much dirt can compact the soil, reducing the drain field’s ability to absorb and filter wastewater properly. Avoid using heavy clay soil, as it can prevent proper drainage. Instead, use a light layer of topsoil and plant grass to help with soil stability.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.
