Network System
AL Tayba Village

Submitted to:
Dr. Sameer Shaded
Objectives:
1- Evaluation of the sanitation situation of AlTayba village
2- Design a sewer network system using
SewerCAD
3- Conceptual design of a wastewater
treatment process
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
Household
• All the houses are individual, with
area ranges from 90-200 m²
• The average of household members
is 6 persons per family
• About 66% are in medium
economical situation
Water Supply
The main water Supply is the
municipality water
The average water consumption
ranges from 5-25 m3 / month
Rainfall collection cistern and village
spring
Wastewater System:
There is no wastewater collection
System
Cesspits are used for wastewater
disposal
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
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 .
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
The design constraints:
The velocity range 0.6-3 m/sec
The cover range from 0.8-4 m
The slope varies from 1-12%
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.
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
Conclusions
•
•
•
•
•
•
Total number of manholes: 124 manholes
All pipes are 8“ diameter UPVC
The velocity varies between 0.4-1.51 m/sec
The cover on the manhole varies between
0.83-2.53 m
The maximum distance between manholes
do not exceed 80 m
The total length of the pipes are equal to
3.5 km
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.
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 .
