A biomat is a black, slimy jelly-like, slowly permeable layer of partially decomposed organic waste containing microorganisms that seek to feed and grow in this anaerobic environment.
Septic tanks are commonly used as a part of on-lot wastewater disposal systems. Septic tanks remove settleable and floatable solids from the wastewater.
For most people living in rural areas, collection, treatment, and disposal of sewage must be accomplished on site. A malfunctioning on-lot system results in sewage backup in the household, untreated sewage emerging at the land surface and/or groundwater degradation.
Proper design and operation of an on-lot sewage system hinges on the ability of the soil to absorb and renovate the wastewater flowing from the treatment tank.
The purpose of this fact sheet is to explain what an elevated sand mound is and how, on sites requiring sand mound absorption areas smaller than 2500 square feet, they should be constructed and maintained.
The purpose of this fact sheet is to describe the parts and function of on-lot sewage systems and the regulatory system governing their use
A PSMA/NOF Septic System Inspection provides homeowners or prospective buyers with information about septic system components and current operating conditions. Pennsylvania Septage Management Association (PSMA) and National Onsite Wastewater Education and Research Foundation (NOF)
On-lot sewage disposal systems can fail. Septic tanks can become overloaded or absorption fields can clog. Leaching of untreated sewage can lead to contamination of nearby water wells.
The purpose of this fact sheet is to explain the components, function, and recommended maintenance of an Individual Residential Spray Irrigation System (or IRSIS). Pennsylvania has approved the use of Individual Residential Spray Irrigation System (or IRSIS) as a conventional disposal method for on-lot sewage.
Examples of Alternate systems include: Steep Slope Elevated Sand Mounds, Drip Disposal, Chamber Systems, and Peat Filters (PA Department of Environmental Protection, 2002).
For most people living in rural areas, collection, treatment, and disposal of sewage must be accomplished on site.
The purpose of this fact sheet is to explain the components and function of the Alternate On-Lot Sewage Disposal Systems known as the At-Grade and Shallow At-Grade Systems. Pennsylvania has approved the use of these at-grade systems as an alternate wastewater disposal method for on-lot sewage.
The purpose of this fact sheet is to explain the components and function of the Alternate On-Lot Sewage Disposal System known as Drip Irrigation.
The local Sewage Enforcement Officer (SEO) focuses on system malfunctions. The PSMA certified septic tank inspector focuses on the overall well being and health of your system. On the surface these two purposes may sound similar, but they are not.
The purpose of this fact sheet is to introduce and provide information about aerobic treatment units (sometimes called activated sludge tanks). Aerobic treatment units (ATU) are a common method of biological treatment used in nearly all municipal wastewater treatment facilities.
The purpose of this fact sheet is to inform homeowners about how to obtain low-cost financing for the improvement, repair or replacement of their existing on-lot sewage disposal systems.
F-266. The purpose of this fact sheet is to explain the purpose, components and function of the Geotextile Sand Filter on-lot sewage disposal system known as the GSF System. Pennsylvania Department of Environmental Protection has approved the use of GSF systems as a wastewater disposal method for on-lot sewage.
