CREATION OF AN INTEGRATED OPTIMAL URBAN DRAINAGE NETWORK PLANNING AND ANALYSIS OF CHAMBERED SEWAGE TREATMENT PLANT: A MODEL STUDY FROM PART OF VIJAYAWADA, AP

Water supply system is a part of modern civilization. It indicates the level of advancement in a community. Urbanization along with its impermeable structures is one of the major factor that causes flooding in urban areas. The work preparation involves redesign of drainage network system in labour colony, zone-2, in One Town area in Vijayawada. The sewer lines in the proposed area are identified by topographic survey and those are geo-referenced by using the software Arc Map to know the exact sewer lines. Statement of Hydraulic Parameters and Flow Characteristics of sewer lines are designed by using Manning's Formula. The wastewater collected from main drains is discharged into sewage treatment plant (UASB) in Jakkampudi which is the sewage treatment plant of zone-2 area in Vijayawada. Aeration Tank and Secondary Clarifier in UASB are analyzed by means of Staad-Pro
