The Past situation for
wastewater system
 During the occupation period, wastewater Sector
used to be a very neglected issue
• There are collection networks in the main cities
and refugee camp (served 28-32% of
population) remaining population uses cesspits
• Many of these networks are old and poorly
designed established before 1967 through
Jordanian Administration and stayed without
development
April 8, 2015
3
The Past situation for
wastewater system-continued
• 40-50 MCM/Y of ww is generated, around
15 MCM/Y is collected by network then
discharged into open areas (wadis)
• Around 400 locations for vacuum tankers
for discharging ww
• There are very few un-functional
wastewater treatment plant (94% of ww is
discharged to wadies)
April 8, 2015
4
The Past situation for
wastewater system-continued
• The un-treated Wastewater flows into the
wadis
• Some farmers use the mixture of both
untreated wastewater and spring water in
irrigation specially in Nablus and AlFar’a
area

Status of WW management in
Palestine !?

Israeli Colonies effects on the
Environment
• Israel is controlling the Palestinians for 40 years
but they did nothing to protect the environment
• Israel moved most of internationally forbidden
industries to the West Bank and disposes all
toxic effluents into Palestinian land without
tratment
• 95% of the industry in the sraeli settlements is
considered toxic & dangerous industries
April 8, 2015
9
Israeli Colonies effects on the
Environment
 Total effluent seawage discharged to the
Wadis by Israeli Settlements is around 50
MCM
• Palestinian Agricultural lands around the
settlements were destroyed by untrated effluent
April 8, 2015
10
Israeli Colonies effects on the
Environment
the last 10 years, The Palestinians allocated
250Millin USD for WWT projects but the
Israelis stopped us by one way or
another
HOW!!!:
• Security Areas
• Connection of Illegal settlements
• High Standards & Specifications

Despite all what have been done, still
huge efforts are needed to properly
manage the wastewater in Palestine
April 8, 2015
23
Challenges1: Water Supply
Priorities
• Providing drinking water systems takes the
priority where still more than 220
thousands in around 220 communities
without networks
• Chaleenge2:
Raising huge amount of fund to improve
WW sector services more than billion US
Dollar are needed
April 8, 2015
24
Challenge2: Limitation of fund
and donor regulations and
requirements
• Challenge3: unsustainability & stability of
External Donation
Donor funds only to have sustainable &
sanitation infrastructures, PWA policy and
strategies should carefully considers the
affordability of beneficiaries to pay for this
service
April 8, 2015
25
Challenges
Israeli conditions through JWC that affect,
postponds, stop projects for unreasonable
aspects
• Connection of illegal Israeli Settlement
effluent to Palestinian Sewerage Systems
• Specifications and standars of effluents
and treated ww imposed by Israelis
• Security aspects
April 8, 2015
26
Challenges
• Challenges4: selection of Appropriate treatment
systems and technologies
that leads to WW management driving forces and
treatment technologies that achieve specific
criterias by utilizing all type of technologies that
help to minimize the running cost, example:
produce gas CH4, incineration of sludge and
available solid waste
April 8, 2015
27
Driving Forces for WW
Management
• Public health risks: waterborne diseases
• Environmental protection: water resources and
soil
• National and regional policies: standards and
guidelines
• Adequate sanitation services: life quality
standards
• Economical benefits: reuse and recreation
• Political issues: regional stability
April 8, 2015
28
Criteria for WWT selection
• Satisfactory treatment efficiency towards: COD/BOD, suspended
solids, N, P, etc.
• Robust technology: high stability towards power cut, peak loads,
toxicants, etc.
• Flexible with respect to future amendments (extensions,
improvement)
• Simple in operation maintenance and control
• Limited number of treatment steps
• Absence of disposal problems (e.g. sludge)
• No malodour nuisance
• Availability of local experience
• Designed for (by) product recovery
April 8, 2015
29
Challenges
Challenge 5: Upgrading of the West Bank
old urban sewage works
• Odor nuisance:
-Overloaded pond systems
-Misconception in design
• Land availability:
- No space for extension
April 8, 2015
30
Challenge 6: Final effluent
disposal
 Reuse in agriculture: where, this was one of the main
target of Master Plan started in 1996
• Treated ww recycling and reuse is considered a very
important option for generating additional water
resources to replace fresh water used for
agricultural and industrial purposes
 Artificail Recharge through Disposal final effluent in
Wadis: environmental impact; compliance with
political agreements
April 8, 2015
31
Challenge 7: Enforcement of
policy and laws
PWA policy:
• Based on “Polluter Pays Principle” and
envisages a full cost recovery based on
affordability basis, water-tariff models should be
developed to assure cost recovery
Palestinian Water Law:
• - Set of regulations and rules entailing pollution
fees for environmental pollution handlings
April 8, 2015
32
Challenge 8: Capacity building
• Building and maintaining a core staff for
managing and regulating the wastewater
projects: review of documents and
formulation of future plans
• Prepare for all training and capacity building
program that required to support sustainable
operation of the WWTP, and to achieve value
from reuse of the treated wastewater.
April 8, 2015
33
Look into the Future
Sustainable planning of WWTP
WW treatment facilities
• Realistic planning and management?
• Affordable CAPEX and OPEX?
Political issues
• Sovereignty?
• Political power?
• Commitment?
April 8, 2015
34
Look into the Future
Sustainable Operation Small
WWTP
Financial Resources
• Effective financial management
• Socio-cultural aspects
• Public awareness and cleaner production tools
Institutional issues
• Establishment of wastewater associations?
• Private sector involvement in sanitation services
• Pollution control & reuse guidelines?
• Water quality & public health protection?
