摘要

BERMAD reducers were set on the town water piping of Ceske Budejovice in 1998 (Czech Republic, 100 000 inhabitants). It enabled the fluent pressure regulation within the whole distribution network (the length of the water piping is approximately 350 km). The system comprises 9 reducers of the dimensions of 150 / 300 mm connected to the water control. The main reducer is controlled on the basis of the table of quarter-hour values defined according to the week's consumption curve, others are completed with the B.E. Controller unit, which has the function of local automatic machines. Their task is to provide the preference consumption of drinking water from the proper sources and controlled regulation of night pressures. A similar system of the distribution pressures regulation, however controlled on a basis of really measured pressure in the water network was applied on the water piping of the Milevsko town in 2002 (10 000 inhabitants, the length of the water piping is 32 km).
