Below are two video’s of a septic tank that went 25 years before septic pumping maintenance. When a tank is completely full of solids, and that’s about 200 cubic feet of NOT mud, it’s extremely difficult to remove. And expensive. A septic pumping should take about 20 minutes.
A neglected system, such as this one, takes about 3 hours. And a lot of back breaking work, and we have to add a lot of water. Our trucks cannot haul solids by themselves. The trucks need water to carry the solids to our trucks. It’s hard on our trucks as well. That is why it is so expensive. Plus we have to repair any damage done to the drainfields.
