- Aim of the project
The project aims at establishing the collecting,
transferring and disposing of municipal solid waste as an efficient, regular and
economical service which follows the steps of preserving the environment. The
project covers 11 municipalities that provide services for 300 000 citizens in
the governorates of Khan Younis and Deir el Balah.
- Introduction
Prior to the establishment of the Palestinian Authority
in the Palestinian lands in Gaza Strip in 1994, the management of solid waste
was the last item on the list of priorities in the agenda of the Israeli
military rule in Gaza Strip. The bad practices in Gaza Strip with the absence of
legislation and inspection mechanisms during the Israeli occupation resulted in
inefficient and inconsistent collection services. On many occasions, waste was
being dumped in open areas, farms and valleys or in some non-hygienic places in
various places in Gaza Strip. This represented a looming danger to the public
health and the environment, and particularly to the ground water resources,
which are already poor.
The project of solid waste management including 11 municipalities in the two
governorates of Khan Younis and Deir el Balah started in 1994. The main problem
at that time was how to achieve the general aim of the project in every
municipality in the governorates, taking into consideration the financial limits
of the project, especially that some municipalities had a population not
exceeding 3000 citizens while others reached 90000 citizens.
The idea of privatizing cleaning services was unknown and impractical because
the standards, principles and cost of such services were unknown at that time.
In effect, the regional solution was adopted, i. e. enshrining the eleven
municipalities under one specialized institution (common services council). The
following steps were designed to acquire the goal of the project:
- Establishing a common or regional service council specialized in solid waste
management for the municipalities within the domain of the project in the
governorates of Khan Younis and Deir el Balah.
- Providing the service of waste collection regularly and efficiently for at
least 90% of the population within the boundaries of the projects. This required
the proper machinery and systems for garbage collection as well as constructing
garages and offices.
- Pursuing steps for solid waste disposal that preserved the environment, and
closing the random non-hygienic open dumps and erecting one central dumpsite
with environmentally accepted standards.
- Adopting an effective administrative system to manage solid waste within an
institution that functioned on the bases of cost recovery to guarantee
continuity in providing the services of garbage collection and disposal.
- Establishing the Institution
The Council for Solid Waste Management in the governorates of Khan Younis and
Deir el Balah was established in 1995 in collaboration with the German Agency
for Technical Cooperation GTZ, as a governmental company in charge of
implementing technical projects within the German governmental external aid.
The role of GTZ was to provide the infrastructure of the project such as the
garages, the waste dumps, the machinery and the technical support. The role of
the Council (the Owner of the project) was to provide the working force cadre
and the land, as well as implement the project and paying the full costs of
operation. The heads of the eleven municipalities were members of this council.
The Palestinian ministry of local administration has approved and endorsed
the council as an independent institution that works on commercial non-profit
basis with a special system unlike that of other government institutions, and
endorsed its ownership by the member municipalities. The reference of the
council was the ministry of local administration. The council composed of the
following departments:
- Administration, with 5 employees (1director, 2garage operators, 1 accountant
and 1 secretary)
- Garages, with 33 workers (12 drivers, 18 workers and 3 technicians)
- Waste yard, with 5 workers (2 observers and pump operators, 1 bulldozer
driver & 2 guards)
- Orientation Unit, with 7 female employees (2 in charge and 5 guides).
- Total: 50 employees and workers.
- The Services and systems used
The Council for Solid Waste Management carries out the secondary waste
collection process (by machines), namely, emptying garbage containers and
transferring garbage to the central waste dump. Those services are enjoyed by
more than 240 000 citizens divided on 11 areas, villages and cities. As for
sweeping the streets and door to door garbage collection, i.e. primary
collection; It is the responsibility of the local municipality.
4.1 Garbage containers
There are a total of 1770 garbage containers, with a capacity of 1000 Litres
each, distributed on all the areas. They are emptied, daily in highly populated
areas, twice or three times a week in villages and once a week in remote places.
Each container is given a position number. The garbage inside a container is
measured throughout the week, and the pace of emptying it per week is decided
accordingly. Air maps are used for determining the places and distribution of
the containers.
4.2 Garbage Collection Vehicles
Non compaction vehicles are used for garbage collection (a truck and a
crane), they collect waste from containers of a capacity of 1000 litres. Using
non-compaction vehicles was adopted because of the high density of waste
reaching 500-kilograms/cubic meter. The system of vehicles and containers was
designed and manufactured in Gaza, and is considered a unique system that is not
used elsewhere and has proven to be efficient.
4.3 The Central Waste dump site
The area of the whole dump site is 70 000 square meters, its first stage
which is currently in service occupies an area of 34 000 square meters. It
provides services for 11 areas and cities as well as five refugee camps in the
two governorates of Deir el Balah and Khan Younis, i.e. about 345 000 citizens.
This site is run by the Council for Solid Waste Management and services the
council's member municipalities. It also services other beneficiaries such as
the United Nation's Relief and Work Agency UNRWA, which collects wastes from the
refugee camps in the two governorates and uses this site according to annual
contracts. It receives about 240 tons of waste every day (88 852 tons for the
year 1998) according to the documents of the weight bridges in the dumpsite.
4.4 The Standards and Operation of the Dumpsite
- The total area of the floor of the dumpsite is liquid proof, it is coated
with a special tar in order to prevent the seepage of leachate into the ground
water (leachate are ten times more polluting than sewage water).
- Leachate is collected in a pond, which is then pumped out and re-circulated
by spraying on top of the waste to evaporate and keep the waste wet, which helps
in speeding up the waste decomposition process. Usually, in coated dumpsites,
the leachate is pumped to the sewage system and then to the water treatment
plant, but since in Gaza, there are no water treatment plants at the moment, the
technique of re-circulation is being used.
- The capacity of the first stage of the dumpsite is 440 000 cubic meters with
a lifetime of nine years. The capacity of the second stage is 400 000 cubic
meters with a lifetime of six years.
- The waste vehicles are weighed at the entrance of the site, and then are
directed to the designated place for dumping. A special bulldozer piles the
waste in layers 3-5 meters thick, where the density of the garbage reaches
1700-kilograms/cubic meter. This density is considered high if compared to
densities in other dumpsites.
