Dr. Sameer Shaded

2. Objectives: 1- Evaluation of the sanitation situation of Al-Tayba village 2- Design a sewer network system using SewerCAD 3- Conceptual design of a wastewater treatment process

3. Study Area
Al-Tayba is located in the north of the West Bank, 18 km northwest of Jenin city.
It has a population of 2407 person
The village is a hilly area, and drain into two wadis
The climate is subtropical with rainfall limited to the winter months

4. Household
All the houses are individual, with area ranges from m²
The average of household members is 6 persons per family
About 66% are in medium economical situation

5. Water Supply The average water consumption ranges from 5-25 m3 / month
The main water Supply is the municipality water
The average water consumption ranges from 5-25 m3 / month
Rainfall collection cistern and village spring

6. Wastewater System: There is no wastewater collection System
Cesspits are used for wastewater disposal

7. Solid Waste
About 15 m3 of solid waste are generated by AL Tayba village every day
The solid waste are transported to Zahret AL Finjan Sanitary Landfill
There is no solid waste containers in the village

8. Designing the Sewer Network
Contour map for the village
Detailed plan of the village, including houses, main streets
The population data from the PCBS
The water consumption from the village council.
The collected data through the questionnaire .

9. 2- Network Design:
Estimate the manhole loads:
1- The area served by each manhole is labeled
2- Calculating the load for each manhole
3. Determine the manhole locations

10. The design constraints:
The velocity range m/sec
The cover range from m
The slope varies from 1-12%

13. Wastewater Treatment Plant
The first option:
use the following units:
Screen, Grit Chamber and Primary Sedimentation Tanks.
The second option:
Use the following units: Screen, Septic tank and Sand Filter.

14. WWTP Area: The required area for WWTP is 550 m²
It is required 320 m² for the treatment units and 230 m2 for operation units

16. Conclusions Total number of manholes: 124 manholes
All pipes are 8“ diameter UPVC
The velocity varies between m/sec
The cover on the manhole varies between m
The maximum distance between manholes do not exceed 80 m
The total length of the pipes are equal to 3.5 km

17. According to the designed sewage system there are two alternatives:
1- Two separate local WWTPs with preliminary and primary treatment.
2- One pumping station and one WWTP.

19. Recommendations it is strongly recommended to establish
a sewage system for Al Taybeh.
It is also recommended to create an awareness towards the reuse of wastewater in agriculture .
