New style septic tanks can be attracted from a distance

Septic tank, designed and manufactured by Ba Ria - Vung Tau Urban Drainage Company, is made of precast concrete, there is an inspection pit located outside the house. When you need to suck or pass, you just need to thread the suction tube through this manhole to get into the tank.

New septic tanks are applied to street houses. The tank is made from prefabricated concrete components, with 1 or 2 compartments to handle (depending on requirements). The waste water after sludge separation will flow out to prevent the washing water of both the house and the outside from passing through the common system. When it is necessary to draw sludge, people will use a nozzle to pass through the inspection manhole in front of the house, slipping into the septic tank.

With old-style septic tanks, when sediment is removed, people must open the tank lid, suck and bring waste through the house. New type of septic tank, due to being sucked through an intermediate manhole located outside the house, should overcome this inconvenience.

According to engineer Nguyen Van Trung, a member of the project, the great advantage of a new type of septic tank is that it is made from pre-cast concrete so the installation is quick and has a much higher life expectancy than a brick built tank. , anti-corrosion, anti-corrosion. The tank has a cost of only 1/3 compared to the old-style tank, while reducing the capacity about 4 times compared to the current one.

New type septic tanks have been experimentally implemented by Urban Drainage Company in some houses in Vung Tau, giving good results.
