In the world of sewer system technology, less is more. The E/One Sewer system requires only a shallow trench and small 2- to 4-inch diameter piping. So, unlike conventional gravity central sewers, which use 24-inch pipe and require deep excavation, the E/One Sewer system is not destructive to the landscape's natural or built features. It also costs significantly less to install and operate than a gravity system. It requires less maintenance. But it guarantees big results.
Here's the idea behind
the E/One Sewer system: Both the gravity sewer system and the E/One
Sewer system are known as central sewer systems. (Septic systems
fall into a whole other category of waste disposal — see "The
High Cost of Septic Systems" on the following page.) Most cities
and many villages use central sewering, which simply means that
waste is transferred, usually by a pipe or main, to a central treatment
plant.
Gravity sewers are the "original" central sewers, with origins in the Roman aqueducts. Unfortunately, the technology behind gravity sewers is also centuries-old: they're bulky systems using a large main and can require major excavation to install. They must be accurately placed and bedded along a continuous downward grade. Plus they're expensive and not entirely efficient in transporting waste because they can tend to leak.
The more advanced E/One Sewer system employs highly sophisticated technology and has become known for its reliability, minimal maintenance, low upfront costs, reduced operating expenses, and ability to be installed at any site, regardless of the challenges of topography. And only the E/One Sewer system with its GP 2000 grinder pump overcomes the challenges of low-pressure systems, performing dependably day in and day out.
Small is Beautiful.
Conventional gravity sewers can use up to a 24-inch large-diameter pipe, or main, which requires major excavation and severely disrupts the landscape and any built structures such as lawns, driveways, and plantings. The E/One Sewer System uses an unobtrusive small-diameter 2- to 4-inch main installed right below the frostline, following the natural topography of the land.
