Mound Septic System Overview

A mound septic system is a specially designed septic system that includes a sand mound built above ground. It uses a pump to distribute wastewater over the sand mound, treating it before it’s absorbed into the ground.

Here’s a quick rundown of how it works:

  • Wastewater Collection: Your house wastewater is gathered in a septic tank.
  • Primary Treatment: Solids settle at the bottom, and fats/oils float at the top while the middle effluent is treated.
  • Pumping: The effluent is pumped up to the mound.
  • Secondary Treatment: The sand in the mound filters and treats the effluent as it seeps down.
  • Final Disposal: The treated water then seeps into the ground beneath the mound.

Mound septic systems are widely used in Woodinville, King County, for being a sustainable solution, especially in areas with high water tables or rocky terrain. They are excellent for preventing groundwater pollution, making them an eco-friendly choice.

Construction Process

  • Site Excavation: The first step is to prepare the ground by removing soil making way for the septic tank and the mound.
  • Septic Tank Installation: A septic tank, usually made from high-quality materials like high-density polyethylene (HDPE), is installed to ensure durability.
  • Mound Construction: After installing the tank, the mound is constructed using selected materials, often a mix of soil and sand, to create an above-ground drain field.
  • Piping: The mound is then connected to the septic tank through a network of quality PVC pipes to prevent leaks.

Getting each step of the installation right is key. This way, you’ll dodge future headaches like leaks, blockages, and the whole system breaking down.
