The method of estimation of the drainage works of a building

Hi Guys, Today we will learn about The Method Of Estimation Of The Drainage Works Of A Building.

The septic tank or suction hole or sewer pipe of the municipal corporation is taken through the sewage house drain from the toilet of the building.

Drainage of rainwater and sewerage on the roof and in the courtyard of the building is provided in the municipal or corporation's surface drain. The following figure shows the drainage system for dirty water and liquid waste.

A truck is attached to the water closet and below the urinal or to the exhaust exit. This prevents the gas stored in the exhaust pipe from entering the building.

A 4 or 5 cm is added to the upward bend of the trap so that the water scene of the trap attached to the water closet is not damaged by the siphon action.

This pipe is called siphon resistant pipe. The other end of the pipe is connected to the vent pipe. The other end of the trap is connected to the soil pipe and the soil pipe merges with the observation located below.

On the other hand, rainwater drainage pipes are connected to open or covered trains. The combined sewage system has a trap with a gate at the junction. This is called abuse trap.

The soil pipe merges into a room on the side of the corporation's road at the land boundary. This chamber is called the intercepting chamber. From here it exits the boundary through an interseptic tank through a manhole located on the road.

Below are all the equipments that are used to remove liquid waste from the building in the combined share system apart from all the above equipments.
