Summary:

The possibility of enlargement of the flood safety of drained terrains of locality Zarzecze using the storage reservoir, accumulating the excess of flood waters was introduced in the work. The worked out conception of the chapter of waters from the ditch R to the pumping station channel was also presented. The lock of the valves of embankment sluices leading the waters of the ditch R to the Vistula river follows in flood conditions, by increasing the level of the water in to the Vistula river. It comes to the outflowing of water from ditch R and submergence of the terrains of the settlement Łączany-Zarzeczein the consequence of the permanent supply of water to ditch R and damming up of water in ditch in the result of the lock of the embankment sluice. In the order to attain o reduce the risk of submergence of these terrains the creation of the storage reservoir from the pumping station channel was proposed. This channel leading water to pumping station Zarzecze. Capacity of storage reservoir and the time of filling up were qualified, founding steady the supply about flow intensity equal to 2,13 m3 ∙ s-1. It was statement that the current technical condition of the pumping station channel with the crown of banks about numerous local lowering, makes possible retention of 4080 m3 of water maximally. The enlargement even above twofold capacities of storage reservoir is possible through surveying the unevenness of the shore line of the pumping station channel.
