What are the limitations of an engineered septic system?
Unlike a regular septic system, an engineered septic system requires a plan, blueprints and approval before it can be put in place. The basic limiting factors that would require this type of tank would be an issue with the soil or rocks beneath the ground and local health ordinances providing restrictions on placement of tanks.
What is a a mound septic system?
A mound system is one of the most common engineered septic systems for areas with high water tables, shallow solid depths, or shallow bedrocks. It uses an elevated mound of sand as the drain field. The septic tank pumps the effluent into the drain field in doses. From there, it’s filtered through the sand and dispersed into the native topsoil.

Is a drip septic system good?
Advantages of Drip Distribution Septic System Most locations can benefit from the drip distribution method. It works well in clay soils, shallow soils, and locations that are somewhat waterlogged. It needs 1 foot of unsaturated soil under the drip tubing and a smaller surface area than a spray distribution system.
What is a pre treated drip dispersal system?
The drip dispersal system is operated via a programmable logic controller (PLC) which is activated by standard float switches located in a dosing tank downstream from a pretreatment process (typically a septic tank).
What is a drip field?
A drip field consists of drip tubing placed along the contour to form a run of tubing. These runs can be connected directly to the supply and return manifold forming a “ladder type” drip zone. The individual runs can be looped together to form a lateral.
How does sand filter septic system work?
The typical sand filter is a PVC-lined or concrete box filled with a specific sand material. A network of small diameter pipes is placed in a gravel-filled bed on top of the sand.

Powell Engineering has been designing onsite wastewater disposal fields of all sizes since 1989. Our designs vary from single family homes to large commercial shopping centers and restaurants. We pride ourselves on our ability to work with the County Health Departments to design a system which will not only function properly on the site, but will be the most economical as possible for the owner.
Why do you have to have an engineer onsite during a percolation test?
Tip: If you think your soils may be questionable it may benefit you to have an engineer onsite during the percolation test because it is much easier for the engineer to work with the sanitarian while calling out soils during the percolation test than after the percolation test when we have not seen the soils. It also allows the engineer to work with the sanitarian onsite to determine the best design for the property.
What is a septic system?
This type of system consists of a series of connected chambers. The area around and above the chambers is filled with soil. Pipes carry wastewater from the septic tank to the chambers. In the chambers, the wastewater comes into contact with the soil. Microbes on or near the soil treat the effluent.

What is a sand mound system?
Mound systems are an option in areas of shallow soil depth, high groundwater, or shallow bedrock. The constructed sand mound contains a drainfield trench. Effluent from the septic tank flows to a pump chamber where it is pumped to the mound in prescribed doses. Treatment of the effluent occurs as it discharges to the trench and filters through ...
What is a decentralized wastewater treatment system?
A decentralized wastewater treatment system consisting of a septic tank and a trench or bed subsurface wastewater infiltration system (drainfield). A conventional septic system is typically installed at a single-family home or small business.
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. The wetland cell typically consists of an impermeable liner, and gravel and sand fill, along with the appropriate wetland plants, which must be able to survive in a perpetually saturated environment.
How does septic effluent get into a sand filter?
Effluent flows from the septic tank to a pump chamber. It is then pumped to the sand filter. The sand filter is often PVC-lined or a concrete box filled with a sand material. Effluent is pumped under low pressure through the pipes at the top of the filter. The effluent leaves the pipes and is treated as it filters through the sand.
Where is effluent piped from a septic tank?
With this design, effluent is piped from the septic tank to a shallow underground trench of stone or gravel. A geofabric or similar material is then placed on top of the trench so sand, dirt, and other contaminants do not enter the clean stone. Effluent filters through the stone and is then further treated by microbes once it reaches ...

Call a few septic installers and ask for a total price including engineering. They'll need to know your square footage and the number of bedrooms you have. Most should have someone they work and communicate well with. Then compare apples to apples in the bids as a total project. You'll save yourself some headaches of being a middleman between the engineer and installer down the line. Regardless, get the engineer's information including license number and phone number as part of the accepted bid just in case anything goes wrong. Also, get the installers license number and any insurance or bonding information he has for your records.

How does community onsite wastewater work?
Each residence has a septic tank to collect wastewater and separate the sludge (thicker solids) from the effluent. In a traditional system, the effluent leaves the tank and is dispersed through layers of soil through a drainfield before it re-enters the groundwater supply as clean water. In a community onsite wastewater system, the effluent is collected from multiple septic tanks and pumped to a singular, larger drainfield that all of the homes share. Increasingly, this wastewater passes through a treatment system prior to final dispersal.

Is a septic system on a lot affordable?
These on-lot septic systems can be very efficient and affordable; however, they severely restrict development opportunities in areas with poor soil or in areas where it would be preferable to have homes on smaller lots and clustered together with larger undisturbed tracts of natural area as a wildlife habitat.
