Site Specific Design proudly sells, installs and services E/One grinder pumps and sewer systems within Pennsylvania and New Jersey.   These modern systems are highly reliable central sewering systems that allow developers and prospective homebuilders use virtually any plot of land, regardless of terrain or elevation changes. Sewer systems using E/one grinder pumps are much more affordable than conventional gravity sewers, which require major excavation, and much safer for communities than septic systems, which can eventually fail, polluting ground and recreational water and endangering public health.
