Paviršinių nuotekų nuosėdų (gatvėje ir nuotekų valymo įrenginiuose) granuliometrinės sudėties tyrimai

Abstract

In water management, to reach optimal exploitation of stormwater net it is required to value particle size witch accumulate on the roads and ways. The sediments from stormwater sedimentation tanks, sediments from Kalvarijų street and from the industrial area (Greičiūno street 35) were taken. Was established particle size of sediments. Research showed that the biggest part of sediments 80 % in sedimentation tank (Verkiai ir Karoliniškės) compose the smallest parts, size – 0,25 mm. Sample from the road that particles size 0,25 compose only 25-35 %. To reduce negative effect to the stormwater net exploitation it is recommended to implement street sweeping.
