What is a Mound System?

The mound system is a most famous and cheap substitute to other septic tank systems. This system installs close to the ground. It doesn't have a chamber for the collection of waste. This septic system removes waste through sand and is absorbed by the ground. It has many advantages and disadvantages. The advantages and disadvantages of this system are as follows.

Mound septic systems have an easy installation than other septic systems. The mound septic system basically consists of digging the site and installing filters and pipes. Other systems require pouring concrete or metal to act as a storage tank. As soon as the storage tank is full, a professional should come out and empty it. However, you don’t need to do this process in the case of the mound septic system because, in this system, the dirt can penetrate the sand. These systems don’t require high repair or maintenance costs.

Construction of Mound System

The mound system has a mound, a dosing room, and a septic tank. Household waste is directed to the septic tank and the solid part sinks to the bottom of the septic tank.

The wastewater is fed into a second tank, a so-called dosing chamber, from where it is dosed and distributed over the hill. The sewage is partially cleaned as it flows through the dunes. The final treatment and disposal take place on the ground below the hill. With a dam system, not all drains can enter the mound at the same time, so wastewater can be cleaned more effectively and system failures can be prevented.

The absorption hill is built up in layers. The depth of the layer is determined by the depth of the restricted soil layer. This can be the seasonal groundwater level, bedrock, aromatic, or glacier cultivation. The standards set by Ohio State University state that the 24-inch floor must be higher than the restricted floor layer. Put a 24-inch layer of sand of a certain size on the ground. The water pipes supplied from the administration room are located on the gravel sand. Next, lay the building material and excess soil on top of the gravel to prevent the pipes from freezing. The topsoil also allows grass and non-wood plants to be planted on the hill to control erosion.

The main drain cleaning and cleaning functions are performed by a loose biofilm around the porous drainage stones. If the soil is very poorly permeable, the liquid will not be absorbed quickly enough. If the soil penetrates too far or is exposed to cracked bedrock, the wastewater reaches the water table and contaminates the aquifer before the biofilm has time to clean the water. In any case, the hill system provides an ideal habitat for the biofilm and has sufficient permeability so that wastewater is slowly taken up by the hill before it enters the area as purified water.

Installing a mound system can compact or disrupt the soil in which the mound is located. Trees in the area of ​​the mound system are felled, leaving roots and tree stumps. Then use a chisel plow to scrape the surface of the hill area. This will prepare a sand surface. In the mound system’s area, work is carried out, so that the descent on the mound is not compacted. The Taylor table is used to determine the size of this septic system.

Time dosing is the most vital feature of the mound system operation. Frequent introduction of wastewater in a short time into a sand filter with widely spaced holes improves the quality of the wastewater. In contrast, on-demand management immediately releases a large amount of wastewater that quickly passes through the sand. As a result, the biota does not have enough time to clean the drain.

Septic Odors Inside the Home

The smell of septic tanks in your home usually means there is a problem with the plumbing, but not all problems require you to call the plumber.

  1. Basement floor siphons can dry out and gas from the septic tank can be diverted into the apartment. You can solve the problem by regularly filling the drain with water.
  2. The plug of the drainpipe cleaning hole may come loose and cause a waste gas leak. Call a licensed plumber to clean the pipe and check the plug.
  3. If the smell is more noticeable in the bathroom, the toilet's wax seal may be dry. Just remove the toilet and install a new wax ring. If the toilet flange doesn't protrude above the tile floor, you can stack the two gaskets.
  4. The ventilation of the roof duct can be obstructed or restricted. As the drain flows, the vent equalizes the pressure in the drain pipe. If the bathtub, sink or toilet rattles, this may be the cause. If the ventilation opening is frozen and just closed, it will defrost as the temperature rises. However, if leaves, bird nests, or other debris block the vents, they should be removed. When climbing on the roof, be careful not to tip over.
  5. The drain pump basket may not be properly sealed. Check the cap and put in a new gasket to prevent further leakage.
  6. Possible causes are holes or leaks under the connections of pipes, drains or sinks.
