Excuse me, what are the steps of water passing test and ball passing test in water supply and drainage engineering?

Pass the ball first, then pass it. Irrigation experiments only need concealed pipes. If there is no concealment, irrigation test is unnecessary.

Irrigation test means that indoor concealed or buried drainage pipes need to be irrigated to see if there is leakage. If there is leakage, it must be treated before it can be concealed or buried. If there is leakage after concealment, it is very troublesome to deal with it.

Passing the test is to check whether the pipeline is blocked. Suitable for horizontal main pipe or main riser, which needs to be checked by water passing test. If there is a big jam, it can't pass the ball.

The drainage test shall be conducted after the drainage system is installed. Drain the whole system once to see if it is smooth. Do the final check.

Extended data

Main components of industrial wastewater drainage system

(1) Pipeline system and equipment inside the workshop: mainly used to collect industrial wastewater in the workshop and discharge it to the wastewater pipeline system outside the workshop.

(2) Pipeline system in the plant area: mainly distributed underground or on the surface, which uses gravity flow to transport wastewater to pumping stations, wastewater treatment stations or urban sewage pipelines.

(3) Sewage pump station and pressure pipeline: mainly used to lift the discharged sewage to a certain height to meet the needs of subsequent structures. After the establishment of the sewage pumping station, the pressure pipeline also appeared accordingly.

(4) Wastewater treatment station: the sum of a series of structures and ancillary structures used to treat and utilize wastewater and make it meet local or national discharge standards.
