Water Crisis and Agricultural Development in Palestine
Palestine Technical University-KadoorieTulkarem, West Bank, Palestine
21-22 May, 2012
Role of Private Sector in wastewater reuse
projects
Global Wastewater Reuse
There is a global trend in
increasing dependence on the
reuse of wastewater as
sustainable non-conventional sustainable non-conventional
water resource for solving the
rising global water stress
especially in arid countries
Drivers for Wastewater Re use in
Palestine
• It converts wastewater that
potentially damages the
environment into a resources that
can improve the environment,can improve the environment,
• It is a sustainable and reliable
resource regardless of weather
patterns,
• It is available where the population
is, and grows with the population
increase, or long distance water
transport,
Drivers for Wastewater Re use in
Palestine
• It reduces pressure on other
raw water sources for potable
uses,
• It is a local solution to water• It is a local solution to water
scarcity where it is difficult to
find additional resources from
elsewhere
• The associated cost of
wastewater treatment and
reuse has proven to be feasible
in many countries worldwide
� The reuse of treated wastewater must be
established in all treatment projects.
� - Co-operation and coordination must be
established with all relevant stakeholders.
Principle of re use strategy in Palestine
established with all relevant stakeholders.
� - Flexible reuse plans should be developed to
enable the reuse and storage in winter season
and when the effluent quality drops below the
standards.
� - Establish planning tools (Regulations,
Standards, Guidelines, etc.) for reuse and
recharge
� Discharge to the surface water may be
considered as an interim action, or if reuse is
not feasible.
� - Irrigation of crops eaten raw is prohibited,
enforcement means should be applied.
Principles….
enforcement means should be applied.
� - For better water quality and reuse efficiency,
consider (i) mixing of treated effluent with
urban and surface runoff, (ii) artificial recharge
of groundwater with treated effluent
wherever possible, and (iii) establish surface
storage of treated effluent with or without
harvested runoff.
� Allow private sector and/or public to manage
or share the management of wastewater
reuse projects.
Principles…..
� - Develop a program for modifying use habits
to include reuse of treated effluent in urban
centers (greening, fountains, urban parks and
landscape irrigation forestation, and other
areas).
� Lack of adequately trained human resources;
current institutional bottlenecks in
WW reuse
� Unclear designation of responsibilities
between stakeholders with a tendency of
insufficient delegation;
� Low level of enforcement - due in particular to
the insufficient number of inspectors, the lack
of monitoring data and equipment, and
conflicts in allocation of regulatory conflicts in allocation of regulatory
responsibilities, plus a culture of producing
data without analysis Legislative change will
not have any effect if enforcement is not
improved;
� Insufficient awareness of issues related to
wastewater; and
� • Lack of a separation of governance functions
from service delivery.

increase population coverage,
� to expand sewage treatment in order to
reduce water pollution and public health, and
primary objectives of the public sector with respect to
private sector participation
reduce water pollution and public health, and
to provide better quality of service.
� to ensure higher operating efficiency and to
finance the system without public subsidies or
guarantees
� service and management contracts, in which
the government retains ownership and full
responsibility for financing, commercial risks
and other vital functions.
� On the other end of the spectrum the
contractual relationship possibilities
� On the other end of the spectrum the
government delegates some responsibility to
the private developers through a lease, a
concession, Build-Own Operate Transfer
(BOOT)/BOOS arrangements, or
� complete transfers of ownership through
divestiture.
Problems with PPP Projects
Many PPPs fail or never achieve
financial close -why?
• Change of policy or personnel by
GovernmentsGovernments
• Commitments required from
Governments prove to be more
than can be accepted
• Long delays mean that projects
become irrevocably stalled
• Change in circumstances or
appetite for bidders
Problems with PPP Projects
• Many PPPs fail after achieving
financial close
• Cost of construction exceeds
expectationsexpectations
• Revenues fall short of
expectations
• Economic factors (example:
currency devaluation)Problems
with PPP
Problems with PPP Projects
• Bidding for PPPs and financial closure of projects
(BOT) invariably time-consuming and expensive
• Costs of preparing bids
• Opportunity costs for senior managers
• Advisers fees and related expenses• Advisers fees and related expenses
• Low success rate / high risk of failure
• Often enabling legislation is not in place
• Few real operators (contractor dominated)
• Lack of discipline or commitment by
Governments
Problems with PPP Projects
Bidders/investors often frustrated by:
• Indecision from Governments
• Poor documentation
• Changes in the timetable or • Changes in the timetable or
process
• Slow decision-making or
inflexibility
• Lack of support at senior levels
• PPP projects compete for investors
time and money
How should Government be involved?
• Select proper and experienced
advisers to the Government
• Perform the feasibility study,
• Fund, and actively participate in• Fund, and actively participate in

documents
• Ensure truly commitment to the
project, and understands what
will be required of it
How should Government be involved?
• Close monitoring and follow-up is
probably best during the negotiation
of the project agreements
• Encourage Investors to make prompt• Encourage Investors to make prompt
decisions
• Close involvement in the review and
evaluation of bids, negotiation of
agreements, closing the financing
• Participate as needed on high levels
How and How much should Government
contribute?
Two methods can be used:
� A discounted cash flow analysis shall be performed to assess the projects’ ability to generate revenue to cover ability to generate revenue to cover costs without a grant
and specifically what percentage of capital costs can be covered. The grant represents the ‘financing gap’ between forecasted
revenue generation and required revenue generation.
• Calculation of the Internal Rate of Return if this is
below an acceptable level, then the grant contribution
should represent that amount required to raise the IRR
to an acceptable level
