Septic Tank Conventional System

A septic tank is a watertight chamber made of concrete, fibreglass, PVC or plastic, through which blackwater and greywater flows for primary treatment. Septic systems treat wastewater from household plumbing fixtures (toilet, shower, laundry, etc.) through both natural and technological processes, typically beginning with solids settling in a septic tank, and ending with wastewater treatment in the soil via the drainfield.

Flexcevator

The Flexcrevator is a portable vacuum system coupled with a trash excluding attachment. Our unique device aspirates fecal sludge while simultaneously leaves trash in pits. By separating fecal sludge from trash during operation, we reduce the risk of jamming in the vacuum hoses. This makes the overall process of emptying more sanitary and hygienic.

Powered Pumps

There are a wide variety of powered pumps (rotary vane, centrifugal, diaphragm, piston, etc). All move a fluid by reducing pressure on the intake side so that ambient pressure pushes the material to the pump. On the discharge side, the pump creates a pressure higher than ambient and pushing the fluid out.

Combined Sewer

These networks have storm drains that are connected to the sewerage such that rainfall is also directed to the treatment plant. Combined sewers have higher operating costs due to the larger volume of wastewater that has to be treated, and they may require larger treatment plants, as well. In addition, when it rains very hard, the treatment plant will not be able to keep up, which can result in untreated wastewater being dumped into the plant's outfall, which may be a river, lake or ocean. Approximately 800 cities in the U.S. have combined sewer systems that are designed to overflow in heavy rains leading to at least some raw sewage entering lakes and rivers.

Conventional Gravity Sewer

The baseline for modern conveyance methods. Sanitary sewers transport wastewater from homes and businesses. Gravity sewers require pipes be laid at slope of 0.5% to 1.0%. For a gravity system to work, sometimes a 10-foot-­diameter tunnel might have to be dug to a depth of 82 feet at the other end

Pressure Sewage

Pioneered in 1969 by Environment One Corporation (E/One, Niskayuna, N.Y.), ATS pressure sewers are found today in 42 countries and U.S. territories, and on almost every continent. E/One’s ATS begins with a grinder pump station, which has a tank about the size of a dishwasher that is buried in the ground, its lid easily camouflaged with minor landscaping. Inside, the primary component is a 1-hp, semi-positive displacement pump.The pump’s robust torque can propel wastewater through small-diameter, inflow-and-infiltration-free pressurized pipe buried just below the frost line for a distance of more than two miles — or even straight up 186 feet — to a force main or treatment plant. The total dynamic head provides a nearly identical flow rate regardless of the network’s contours and fluctuating elevations. Investment costs can be up to 50% compared to conventional sewerage. Blockages are more common.

Simplified Sewer

Also called small-bore sewerage, is a sewer system that collects all household wastewater (blackwater and greywater) in small-diameter pipes laid at fairly flat gradients. It is suitable for existing unplanned low-income areas, as well as new housing estates with a regular layout. Investment costs can be up to 50% compared to conventional sewerage. Blockages are more common.

Solids-Free Sewer

Effluent sewer systems, also called septic tank effluent drainage (STED) or solids-free sewer (SFS) systems, have septic tanks that collect sewage from residences and businesses, and the effluent that comes out of the tank is sent to either a centralized sewage treatment plant or a distributed treatment system for further treatment. Most of the solids are removed by the septic tanks, so the treatment plant can be much smaller than a typical plant. In addition, because of the vast reduction in solid waste, a pumping system can be used to move the wastewater rather than a gravity system.
