What is a low-pressure sewer system?
The E/One Sewer system is a low pressure sewer system that is powered by E/One grinder pumps. A low pressure sewer system uses small-diameter pipes and grinder pumps, which are often installed at each home. The grinder pump station collects all of the wastewater from the home and grinds it into slurry. The wastewater is then pumped to a larger sewer main or directly to a wastewater treatment plant.
Low-pressure, gravity-independent, contour-following sewage collection systems were pioneered by Environment One. E/One Sewer® systems have proven to be an economical and effective method of sewering even in difficult land areas, such as flat, wet, rocky and hilly terrain.
At the heart of an E/One Sewer® is the Grinder Pump, developed by Environment One. These units accept household sanitary waste, grind it into a fine slurry, and pressurize it to permit transport through small-diameter pipes. E/One Sewer Systems serve over 500,000 end-users daily.
Gravity vs. Low-Pressure
While gravity sewer systems often use large mains that are installed in deep trenches, pressure sewer pipes may be as small as 2 inches in diameter and follow the contour of the land. Installation using these small trenches can equal huge savings in development costs.
What is Prefurbia?
Perfurbia is a collection of innovative development and neighborhood design methods used to solve many of the problems experienced in land preparation without sacrificing the individual desire for space, affordability and overall quality of life.
Prefurbia offers a higher standard of living for both suburban and urban densities. It exceeds minimums creating a preferred way to live, work and play.
What is Autoclaved Aerated Concrete (AAC)?
Autoclaved aerated concrete (AAC), also known as autoclaved cellular concrete (ACC), autoclaved lightweight concrete (ALC), autoclaved concrete, cellular concrete, porous concrete, Ytong, Hebel Block, Aircrete, Thermalite, or BCA, was invented in the mid-1920s by the Swedish architect and inventor Johan Axel Eriksson. It is a lightweight, precast building material that simultaneously provides structure, insulation, and fire- and mold-resistance. AAC products include blocks, wall panels, floor and roof panels, and lintels.
It has been refined into a highly thermally insulating concrete-based material used for both internal and external construction. Besides AAC's insulating capability, one of its advantages in construction is its quick and easy installation, because the material can be routed, sanded, or cut to size on site using standard carbon steel power tools.
Even though regular cement mortar can be used, most of the buildings erected with AAC materials use thin bed mortar in thicknesses around ⅛ inch, depending on the national building codes. AAC materials can be coated with a stucco or plaster compound to guard against the elements, or they can be covered with various siding materials including brick or vinyl.
AAC has been produced for more than 80 years, and it offers several significant advantages over other cement construction materials, one of the most important being its lower environmental impact.
