Modeling & analyzing of network :

Future analysis for the existing network

Data Collection :

Modeling & analyzing of network after 30 year: q For the distribution of the future population we assumed that the density of the building in middle areas ( main street area ) of the village will stay the same (fixed density areas) q the expansion in the building will be in the areas which its density is smaller than the middle areas (unfixed density areas) q the increased population will uniformly distribute in the unfixed density area

Design waste water collection network q Al-Zababida town doesn’t have a wastewater network q The terrain of the town allows to use gravity system, to let the wastewater goes downwards q The contour line of the town shows that the lowest point in the town located in north region. q Sewer. CAD software will be used to design the wastewater networks

Design waste water collection network The assumption that will considered in the design is: q Design period 30 years. q Future Population = 8810 capita. q 120 L/c. d water consumption q 80% of produced waste water from consumed water. q 20% infiltration. q The maximum distance between manholes is 30 m. q PVC circular pipes.

Design waste water collection network The constrains for the design of WWCN are: q Velocity between (0. 6 – 3) m/s. q Cover between (1 – 5) m. q Slope between (1 – 4) %

Result of Design WWCN q All the diameters in the network are 8 in

Cost estimate for WWCN To estimate the total cost of network, 4 main parts should be considered: q Excavation and filling cost q Conduits cost q Manholes cost q Repaving cost

Cost estimate for WWCN q Conduits cost(8 in) = 40 x 22780. 9 = 911236 $ q excavation of pipes tracks and filling = 30 x 22780. 9 = 683427 $ q Manholes = 650 x 798 = 518700 $ q Total cost = 2113363 $

Problems that was solved q Problem of the Hard and the quick change in topography and slops. solution: v Changing the direction of the flow and enlargement the distance between manholes

Problems that was solved v Adding more than one outfall One outfall two outfall

Problems that was solved three outfall

Problems that was solved q Problem of minimum velocities and high cover. q After the Trying many cases, the velocities of the flow were very small in general because of the low population q This problem can solve by increase the cover constrain range but that affects to make a huge cover depth

q The cases of the slope rang and its effects on covers: slope: 1% to 12%

Problems that was solved Slope: 1% to 4%
