Abstract (en)
[origin: EP0845561A2] The drainage system includes storage sections (A) which hold back fluid volumes for release when the main flow is low. each storage section has a weir (3) to hold back a volume of fluid. A siphon (S) is fitted over the weir with the upstream end (21) at a set height above the floor of the drain and with the outlet end (23) having a sump section (25) below the floor of the drain. The siphon is controlled by a valve. The storage section holds back fluid when the drain flow is low. When required the siphon is activated, by the valve, to discharge to storage volume into the drain and flush away any solid residues.
