摘要： A booster station (5) of sewage water, in which the startings and stoppings of pumps (6) installed in it are controlled by means of pressure prevailing on the suction side of the pumps or in frequency converter drives by means of frequencies. The invention is implemented such that the pumps (6) of the booster station (5) have a common inlet pipe (7) of the suction side which branches from a previous pumping station or an equivalent incoming inlet pipe (4).
