Abstract
Industrial wastewater is highly polluting the environment if not handled properly, also
affect the wastewater infrastructure for both collection and treatment. Most of
consumed water is converted to wastewater from residential, industrial, and commercial
uses. Industrial wastewater is a critical concern for all industrial settings that lacks the
infrastructure to handle such water.
Generally, industrial wastewater in Palestine represents a major challenge to the
environment and municipal infrastructure, mainly in the industrial cities like Nablus
city.
This thesis aims at concluding the most appropriate solutions which prevent or decrease
the hazards resulted from industrial wastewater on the wastewater infrastructure and its
operation. The research utilized the risk based management approach to propose
proactive and reactive barriers for industrial wastewater hazards and impacts. Cost
Benefit Analysis was used to estimate the costs and benefits for Nablus municipality for
each identified barrier.
Risk analysis was carried out to explore the hazards and impacts of industrial
wastewater on the infrastructure; Wastewater Network (WWN) in Nablus and Nablus-
West Wastewater Treatment Plant (NW-WWTP). Risk evaluation was used to priories
the hazards through the calculated risk priority number (or degree of severity) to
quantify risk.
Results showed that industrial wastewater, which had risk priority number of 9 poses a
significant threat to the municipal infrastructure. Infrastructure damage and operational
inefficiencies were resulted.
To reach this thesis's goal, estimated proposed strategies to reduce negative impacts
were discussed in risk control approach.
After conducting risk cost benefit analysis for Nablus municipality, it is found that
awareness and WWN rehabilitation have to be excluded because their proportion Factor
(d) is more than 1, but the other barriers should be executed by the municipality. Since
equipment insurance barrier has the smallest d which is 0.0036, it has to be prioritized.
Then, to execute the remaining barriers from smallest d in ascending order.
Finally, risk based management approach and risk cost benefit analysis options are very
useful tools to mitigate and adapt hazards to improve the preparedness and response for
Local Governmental Units (LGUs), particularly in the field of wastewater management.
The results of this thesis should guide the implementation of effective management
practices that ensure environmental protection and infrastructure resilience.
