`water distribution network Objectives The main objective of this project is: To analyze and design of the WDN for the South- East Industrial Zone of Qalqilia City using WaterCAD `water distribution network

Introduction Water distribution network is necessary in order to facilitate the process of providing consumers with clean water and quantity that suit their needs and control the quality of this water because the presence of this network ensure unpolluted water and access to consumers with best quality.

B) Wind The prevailing wind direction in Qalqilia, southwest and northwest at an annual average speed of 3.4 km/h C) Rainfall Average annual rainfall in Qalqilia= 559 mm The average number of rain days= 40-60 days.

Sources of water in Qalqilia Rainfall B) Evaporation C) Groundwater D) Wells Gayyaza Well Al Wakalah Well Al Maslakh well Sofin well Abd Al Rahman Well

located at the South- East part of the city center. D: The Source of water for distribution network of industrial zone The main sources is: Abd Al Rahman Well: located at the South- East part of the city center. Its depth is (100-120) m. water level in the well (20-25) m. diameter of the well is 0.5 m. designed to produce 90 m3/hr .

Data related to the study area: Contour map. Information from Qalqilia Municipality AutoCAD and GIS data.

Water demand Represent the necessary minimum amount of water sufficient to meet the basic need for drinking, sanitation, and water uses; it might be extended to include the water requirements for a particular purpose such as irrigation, municipal supply and storage.

Registered professional shops and light industries in Qalqilia Professional Shops Light Industry The Num Auto oil shops 5 Building Material shops 20 Auto spare shops 30 Carpentry and Blacksmith tools shops 12 Tailoring workshops 70 Electrical appliances repair workshops 27 Gold shaping workshops 3 Carpentries 47 Blacksmith and lathing workshops 55 Auto general mechanic workshops 53 Car wash and oil changes workshops 13 Auto body repair and painting workshops 40 Auto electrical repair workshops Auto tire repair workshops 14 Aluminum window/door assembly workshops 19 Tiles and block making factories 4 Stone cutting factories Granite making factories 6 Tissues making factories 2 Meat canning factories Total 440

The average water consumption for registered professional shops and light industries is about 700 l/d/unit.   The total number of unit= 440 unit The total water consumption for Registered professional shops and light industries = 440 * 700 = 308000 l/d = 12.83 m3/hr.

The water demand for expected factories Water demand for total area(m3/hr) Water demand Per Area (l/s/ha) Total area (ha) Num Area (ha) Type of industry 1.4 0.78 0.4 1 0.5 Food & beverage 0.52 0.43 0.34 Chemical &Cosmetics 1.86 0.7 0.74 Building material 0.31 0.2 Textile & Clothing 0.29 2 0.17 Plastic & Rubber 4.43   2.02 6 Total

Total water consumption for industrial area = 4.43 + 12.83 = 17.26m3/hr Peak factor = 1.5 Design water demand = 17.26*1.5 = 25m3/hr

Water tank design  

The water demand for working hourS The capacity of tank: The water demand for working hourS

From the chart, 75-25 = 50 m3/hr The capacity= 50*8 = 400 m3 Now, we add 100 m3 (Fire) The capacity= 400+100(fire) = 500 m3 The cross section for the tank is Circular With diameter = 11m

Number of hour to fill the tank= 16 hour Time schedule to fill the tank

Water CAD Software Water CAD is a powerful yet easy to use program that helps engineers design and analyze complex, pressurized piping systems And Water CAD help to analyze multiple time-variable demands at any junction node.

Preparing data Junction : Elevation → contour maps Demand rate → We distribute the demands on the junctions as the following: And For the remains junctions the demand = 1.3 m3/h Junction Demand m3/h J-1 2.79 J-2 2.1 J-12 0.51 J-13 J-14 0.47 J-20 0.78

pipe 1 . Find the length of each pipe using WaterCAD program. 2. Specify start and end node for each pipe. 3. Assume an adequate diameter for each pipe. 4. The materials for the pipes is PVC , The roughness of it is 150 as reported by C = Hazen-Williams roughness Coefficient.

Design considerations After running process, checks have to be made to make sure that the velocity in pipes and the head at nodes fulfill required criteria which indicate that:   Allowable nodal pressure arranges between (20-80) meter head. Allowable velocity in the pipes arrange between (0.3 −3) meters per second.
