AL-Ghadir Project Characteristics (priority project)
•
•
•
•
•
•
Listed as a pollution hot spot for the
Mediterranean sea stated in Lebanon NAP;
Responds directly to Med. Sea De-pollution
initiative;
Wastewater sector is a priority area of
intervention for Lebanon;
Existing plant provides inadequate level of
treatment (screening + Grit & Scum Removal);
Its upgrade was initiated some ten years ago (Feasibility Study,
Study in 2000,
2000
no investment followed);
Since 2000 the drainage area was subject to various changes (networks,
main collectors, and urban development);

“TECHNICAL” CONSIDERATIONS &
CHALLENGES
Location of the plant - Drainage area
•
Location of the plant
¾ Southern Beirut, by the Airport
•
Drainage area, basic features:
¾ P
Partt off 4 casas (districts)
(di t i t ) & 47
“Municipalities”
¾ Estimated population of the area approx.
1 million
¾ Mainly urban areas (no agricultural
land); some areas without urban plans
and with limited sanitaryy provisions;
p
;
¾ Sewer networks: mains constructed or
under construction or designed
¾ Limited data available on secondaryy and
tertiary sewer networks
¾ Limited data available on water supply

Potential for Wastewater Reuse

Potential areas for irrigation
Aquifers “known” to suffer from sea intrusion
•
Limitations:
×

×
×
Lack of national regulatory framework (at
preparation stage)
For irrigation: long distance, higher altitude
Æ cost! (distribution network and pumping
cost)
Aquifer recharge: cost (either for infiltration
basins or deep well injection); feasibility of
this potential reuse method would require
detailed hydrogeological survey
Limited motivation to promote wastewater
reuse (not the case for other areas but in
general true for coastal cities)
Solid Waste Management (sludge)

(2002), nott
officially adopted (Ghadir, incineration)
Sludge on a “case by case” basis
Discussions on “Waste to Energy” SWM Plans
initiated (MSW, WW sludge included)
Review of existing facilities on SWM, first
screening (presented in the figure); Naameh
landfill already close to its capacity
Also in the figure, areas (total per district)
available for land application of sludge
Limitations for land application (incl.
composting):
1.
2.
3.
Distance from Ghadir plant
Quality of sludge produced (high metals
concentrations anticipated)
Limited acceptability from competent authorities

Industry in the project area
•
•
Industrial areas (previous study, 1996)
Lack of data in assessing pollution loads:
¾ Production type, capacity
¾ Existence of sewers, connected or not
•
•
•
•
Compliance
p
of industrial discharges
g ((with
ELVs) reported to be limited (No
enforcement)
Pre-treatment
Pre
treatment on site, rarely applies
Sampling is scheduled, targeting the
identification of major polluters
Work on possible synergy with parallel
project (GTZ funded) to promote
pretreatment (pilot basis, priority areas
and polluters)
Legal Framework - overview and “gaps”
• A comprehensive list of relevant legal acts and ratified
treaties/agreements prepared
• ELVs (discharges) and Environmental Quality Standards
(e g bathing water criteria) are in place
(e.g.
• Legal “gaps”:
– Guidelines and/or standards for ww reuse and sludge
reuse and disposal (prepared, not yet adopted)
– Soil and sediment standards
– Framework Law on ICZM

Institutional Aspects & Shortcomings
• Closer coordination among key Stakeholders (e.g. MoEW,
MoE, WE, CDR)
• A new Strategy on Water Sector Reform drafted in 2010 by
MoEW (still to be endorsed)
• WW sector institutional responsibilities for networks,
treatment, post treatment still vague
• Limited
Li it d experience
i
on WWTP
WWTPs (especially
(
i ll off large
l
scale)
l )
• Operation and Maintenance of WWTPs in Lebanon, is
contracted out by either MoEW or the WE (and monitored)

Cost Recovery and Tariff Structure
• Currently no tariff on wastewater applies
• Water tariff applies per household per year (lack of metering);
average US $138 (assuming 1m3/household/day) (not covering
O&M in most cases)
• New Water Strategy suggests ww tariff to be introduced in 2011
(25% of water tariff
tariff, current water tariff US $0
$0,4/m
4/m3, suggested
ww tariff US$ 0,1/m3)
• WW tariff to apply on customers connected to sewer network
and WWTP

DEVELOPING ALTERNATIVE OPTIONS
Designing Alternative Options
• Inception report is under review; critical aspects highlighted
• Considerations in developing of alternative options:
– Limited land availability; off shore extension feasible but increases cost
(especially if to exceed a certain zone)
– Vicinity to the airport (height of buildings, safety, odours nuisance, birds
etc )
etc.)
– Sludge management (off site, volume – cost, industrial discharges)
– Feasibility of the reuse of the total flow of the treated effluent is
questionable
– Current system of outfalls, suggested to switch function (critical aspect
on site’s hydraulics)
– Limited experience in WWTPs operation (simplicity of the method)
• Comparison of alternatives from a technical, financial and
environmental point of view
