Effluent filters through the stone and is then further treated by microbes once it reaches ...

How does a constructed wetland work?

A constructed wetland mimics the treatment processes that occur in natural wetlands. Wastewater flows from the septic tank and enters the wetland cell. The wastewater then passes through the media and is treated by microbes, plants, and other media that remove pathogens and nutrients.

How Do Septic Tank Field Lines Work?

The septic tank drainfield works in a simple process. The pipe gets waste from the septic tank. The perforated pipe then distributes this among the aggregate. It then trickles slowly through the aggregate. Next, the soil receives this effluent. Finally, in the last process, the soil filters out all harmful bacteria which is present in the waste. It is then returned to the water table.

Why should you be aware of the location of septic tank field lines?

So, how to find septic tank field lines? To find the septic tank field lines start the search from your home. Keep tracing the drain lines towards the septic tank. The septic tank will be installed at least 10-20 feet from the exterior. Since the tank is located just to the opposite side of the house, drain lines go to the leach field. Look at the naturally sloping land and you will be able to find the leach field.

Why is it important to know the location of a septic tank?

Knowing the location of the septic tank is necessary because you will have professionals coming for inspection and maintenance. You will not want to keep looking for the drainfield in their presence.

How does a drain field work?

A drain field is designed in a way to let the liquid from the tank get absorbed in the ground. The solids usually dissolve, and they break down. Liquids tend to flow from the tank and through pipes to the drain field. Next, they exit and move into the ground. They move through holes in pipe. However, with time, this leach field might be clogged or damaged. This can happen because of buildup of material.

How does a septic tank work?

The septic tank operates by digesting solids and settling sludge to the bottom and allowing grease to float to the top of the septic tank. Macerating the sewage before entering the septic tank will create a septic tank without any large solids, just a cloud of ground up sewage particles.

What is a drywell leach pit?

Drywell leach pit kits are best practice for additions and repairs on pipe-in-gravel leach fields. Not venting the end of each leach field lateral line (finger) is the most common cause of leach field failure. Lack of fresh air in the leach field pipes and surrounding gravel creates anaerobic conditions, accelerating bio-mat formation. Best practice is to install at least one drywell at the end of each lateral line finger. An upgrade for longevity is two drywells installed in-series which allows the first to act as a settling catchment, ensuring long-term viability of a failing sewage disposal system by keeping the perforated pipes lines dry most of the time. Drywell system cut sheet with gravel installation detail is available for engineers.

What is the name of the water that is produced by a septic system?

The wastewater your home produces is referred to as 'effluent' and consists of blackwater (toilet and garbage disposal waste) and greywater (shower, sink and laundry waste). Effluent flows directly from your household plumbing into a watertight, underground, two compartment septic tank. Solid waste settles into a sludge layer on the bottom and fats float to the top of the first compartment. Between these two scum layers is a zone of clarified liquid effluent which is internally piped to the second compartment of the septic tank for additional settling. As incoming sewage from the house fills first compartment, clarified liquids are forced to leave the second chamber of the septic tank and flow out to the leach field or leach pit. The typical leach field is a series of chambers or rock filled trenches where effluent is further treated as it slowly percolates through the soil. A leach pit is a deeper, larger hole filled with rock for disposing of wastewater in a smaller footprint. Not as effective treatment as a larger leach field, where sewage percolates slowly over a larger area, leach pits are an alternative for smaller properties only where high seasonal ground water is not present. Greywater from washing machine, sinks and showers contains soaps designed to kill bacteria (clean and disinfect things) and thus discourage optimal septic tank function. You want to encourage helpful good bacteria (digesting anaerobic cultures) to grow in your septic tank and organically treat the waste, not kill helpful bacteria with detergent laden graywater. If allowed by your local building department, it is always best practice to divert household greywater to a separate leaching area.

Why is my septic system failing?

The most common reasons are: single compartment septic tank, no septic particulate filter, under-sized leach field, and lack of leach field ventilation. Oxygen is very important for leach field health.

What is a flow director splitter?

Flow director splitter valve comes complete with adjustment handle, riser, coupler, and four inch threaded access cap. Special staggered hub fittings on the ‘versa-tee’ accommodate PVC or ABS pipe in 4 inch diameter in both Sch40 or thin wall SDR35 sewer drain pipe. Note there is a two inch drop in elevation from inlet pipe (base of tee) to two outlet pipes (top of tee) where the effluent flow splits. Effluent flow can be accurately split 50/50 evenly between the two outlet pipes OR you can alternate the flow 100% to one side or the other. Distribution boxes and simple tee fittings off-level by as little as 1/8 of an inch will be drastically less than equal 50/50 split. But with director valve, even at 1/8 inch tilt, flow directer delivers relatively equal flows (+/- < 1.3%). Diverter allows one half of your septic system leachfield to go fallow for a few months to revitalize soil, prevent overloading, and reduce the growth of bio-matting. Three director valves will allow splitting flow between four separate leach field lines. Then you have the option of letting 1/4 of leachfield to go dry seasonally. Flow director splitter valve fitting is designed for gravity flow systems only. Internal weir divides the flow, this is not a gate valve. Not for use in pressurized pipe dosing systems with lift station pump or automatic siphon. Use two gate valves and a tee manifold instead of a director valve with pressurized or siphon effluent systems. We don't sell gate valves given the extremely wide range of options. Click for flow director splitter valve installation tips.

What is a leach pit?

A leach pit is a deeper, larger hole filled with rock for disposing of wastewater in a smaller footprint.
