Objectives:
Analysis the existing water distribution network.
Redesign the existing water distribution network.
Design a wastewater collection network.






Study area:
Location:

Located in the north of Tulkarem governorate 
    at a distance of about 17km at the north of the
    west bank.

2. Surrounded by Apartheid wall from the west,
    Wadi Abu Nar from the south and some villages
    that surrounds the rest of it.









Location:










Study area:
Topography:

The elevation of Baqa ranges from 60 up to 130 meters above sea level.

This town varies in its terrains, it has three mountains at the east, plain from the west and valley from the south.














Study area:
Population Calculations
	Year	2007	2008	2009	2010	2011	2012	2013	2014	2015
	Pop.	4064	4143	4222	4304	4386	4471	4555	4641	4726

population estimations from the Palestinian Central of Statistics:
The study period is 30 years from now (2015) so depending on these data and using annual compounding method 
We predict the population in 2045,
P(2045) = 9674 capita.
Design demand = 4704.6 m³/day.
Design load = 4015 m³/day. 










Graduation Project 1 Review
Water Distribution Network








 Methodology:










Drawing the existing network








Distribution of houses for each junction in each service area







Redesigning and changing the main pipe size







Results:
 Pressure
 Velocities








Pressure:








 Velocities:











Recommendations:
Pressure reducing valves (PRV) for      high pressure.
Internal pumps for low pressure.
Boosters for low velocities.











WasteWater  Collection Network










Methodology:











Drawing the Network







  Arc-hydro:










Long time
Low accuracy


Shorter time
Medium accuracy


Very short time
High accuracy






Arc-Hydro Method






  Results:

 Cost 











  Cover Depth:












 Slope:












  Velocity:












  Length of conduits:












Cost Estimations:

Considering the prices in our country, 
we estimated the total cost of the wastewater collection network = 1563206$, and the cost per 1km = 72683$. 






  Conclusion and Recommendations:

 Flushing system in the network especially where low velocities    occurs. 

 Implementation of Continuous maintenance to the network.
 
 Constructing a waste water treatment plant to avoid pollution of    the environment and to reuse the treated water for agriculture instead of wasting it.
