Gravity Sewer Systems
Conventional gravity sewer systems collect wastewater from homes and transport it to a collection line by allowing gravity to force the flow of liquid and solids. There are no pumps or pressurized components in tradition gravity sewer systems but this method requires the digging of wide, downward-sloping trenches to serve as an underground path for sewage to travel to its final collection destination. Traditional gravity sewer method is adequate for downhill grades but can be ineffective when there is an uphill slope or ground conditions differ. In addition, gravity sewer systems are not an effective method for wastewater transport in areas with rocky terrain and sandy soil or for application with close proximity to water or with long piping runs.
