The Design of Water And Wastewater Networks For Qilqis For Hebron southern Regions Prepared by Under Supervision of Amer Mutlak Zalloum Dr.Anan Jayoussi.

Outline Objectives Study Area Design Methodology Questionnaire Analysis Water Network Design And Results Wastewater Network Design And Results

Objectives Design a reliable water and wastewater network. Meet the PWA design standards Make sure that the networks performance are acceptable for the required design period.

Study Area This project provided for Qilqis village, which is locate to the south of Hebron city.

Study Area Information about Qilqis: 1- Expected population at the end of the design period=7282 person. 2-Total area=7639 dunums. 3-Density= .95 person/dunum. 4-Cunsumption/Capital=120 L/d. 5-Losses in water network=10.8%. 6-Requierd demand=135 L/c.d. 7-MaxDF=1.6 and MinDF=.45 . 8- Wastewater production=80%*Consumption/Capital=96 L/c.d. 9- Infiltration=20%*Consumption/Capital=24. 10-Harmon’s Peaking Factor=3.1. 11- sewer load/capital =96*3.1+24=321.6 L/c.d. 12- sewer load/Dunum= 306.72L/D/D.

Design Methodology Water And Wastewater Networks Gathering Data AutoCAD Modified Data GIS Loads Calculation/Dunum Drawing Water And Sewer Cad Networks Modifications Thiessen Polygon Run Results

Questionnaire Analysis 1- Availability Of water Distribution Network

Questionnaire Analysis 2-Main Water Source

Questionnaire Analysis 3- Relation between Monthly Consumption/family and Number Of Family Members

Questionnaire Analysis 4- Relation between Monthly Consumption/family and Income (NIS)
