Water Sector in Gaza Strip is living a
Nightmare

General
background
Water is the most precious and valuable
natural resource in the Middle East in general and in Gaza Strip in particular.
It is vital for socio-economic growth and sustainability of the environment. Natural
water sources are divided into groundwater and surface water. Groundwater
includes water that seeps into the ground and is collected in an underground
aquifer but surface water flows is collected above ground, such as in
rivers, streams, and lakes.
Providing
a water supply for a community involves tapping the most suitable source of
water, ensuring that it is safe for domestic consumption and then supplying it
in adequate quantities. Enjoyment of sufficient water of suitable quality
should be classified as a human right. However, human rights documents do not expressly
relate to such a right. The problem of water scarcity in urban areas of
developing countries is of particular concern as the water quantity available
for supply is not sufficient to meet the demands of the population which forcing
people to collect water individually, by means of ground or roof tanks.
Although
it is impossible to set a standard and accepted quantity of water necessary to
meet basic needs, a few principal criteria exist. A person requires from three
to five liters of water a day to exist in the narrow meaning of the term
"human subsistence". The World Health Organization and the United
States Agency for International Development recommend one hundred liters of
water per person as the minimal quantity to meet basic urban needs.
Israel
and the Palestinians share two water systems, groundwater and the other surface
water. Since the beginning of Israeli occupation, in 1967, the demand for water
by Palestinians has increased significantly due to a high influx of refugees in
1948, when approximately 200 000 people fled to Gaza. The original
population of the Gaza Strip at that time was 80 000 people, thus this represented
an increase of some 250%.
The total population of the Gaza strip was estimated in the year 2002 at
1,299,403 inhabitants and the fertility rate was estimated at 3-3.5%.
This rate plays a big role in the planning and management of water resources.

However,
Israel's strict control of the water sector in the Occupied Territories,
unequal division of the shared ground water and exploitation of new water
sources has prevented development to meet the increasing demand for water,
causing a water shortage and crisis.
Despite
international water resources shared by Israelis and Palestinians, the right of
Palestinians to share these resources was not recognized in practice, and the
division gradually became discriminatory and unfair.
Israelis
benefit from advanced and reliable infrastructure for the supply of water for
domestic use, enabling them unlimited water consumption for all domestic and
urban uses. By contrast, Palestinians in the Occupied Territories suffer from
an underdeveloped and unreliable water-supply system for domestic use.
Water
resources availability in the two neighbors is far apart, with fresh water per
capita in Israel about four times that of West Bank and Gaza. Whereas Israel is
known for efficient water infrastructure, Palestinians are struggling to attain
the most basic level of infrastructure and services of a low income country.
Since
the second Intifada in 2000, Israel’s restrictions on movement and access of
goods both within West Bank and Gaza and through Israel to the rest of the
world have had dramatic impacts on the Palestinian livelihoods. The effects of
these restrictions are far-reaching, as they impair planned development,
private sector initiatives and livelihoods across all sectors.
Present
water supplies are neither adequate to provide acceptable standards of living
for the Palestinian people, nor sufficient to facilitate economic development
as a result of the limitation on supply and restrictions on developing new
water resources and supply infrastructure. The limited water resources in the
Palestinian governorates face the challenge not only to supply the various
water sectors with their water demand, but also has to secure water to meet the
increasing needs for people in the future.
Many environmental problems are accelerated and exacerbated by
Occupation practices, which prevent effective environmental management. The
one fact that is indisputable, however, is that the Palestinians have no
decision making power in their own water future. The present situation of
water sector in Gaza Strip and the challenges to be faced are:
·
Water
resources in the region are extremely scarce and disputable.
·
Water
demand is continuously growing.
·
Water
supply and sanitation services are inefficiently delivered and inadequate.
·
Tariffs
are generally inadequate.
·
Consumption
and water losses are excessive.
·
Insufficient
water harvest activities.
Current
situation
The Gaza Strip is a very small area of land -
with a total area of only 360 km2 - was considered of great
strategic importance as the first source of freshwater north of the Sinai
Desert. It is underlain by a shallow aquifer, which is contiguous with
the Israeli Coastal Aquifer to the north as shown in figure 2. Gaza is
the downstream user of the Coastal Aquifer system, and hence water abstraction
in Gaza does not affect Israeli water supplies the flow of Gaza aquifer is
illustrated in figure 3.
Depth
to water level of the coastal aquifer varies between few meters in the low land
area along the shoreline and about 70m along the eastern border. The coastal
aquifer holds approximately 5x109 m3 of groundwater of
different quality. However, only 1.4 x109 m3 of this is fresh
water, with chloride content of less than 500 mg/l. This fresh groundwater
typically occurs in the form of lenses that float on the top of the brackish
and/or saline ground water. That means that approximately 70% of the aquifer
are brackish or saline water and only 30% are fresh water.
The
major source of renewable groundwater in the aquifer is rainfall. Rainfall is
the main natural water source that replenishes the groundwater aquifer, but it
is no longer sufficient to refresh the groundwater system. Rainfall is sporadic
across Gaza and generally varies from 400mm/y in the North to about 200mm/y in the
south as shown in figure 5.
This
aquifer is essentially the only source of fresh water in the Gaza Strip that has
been continuously over-pumped to serve the high population resulting in falling
water levels and degrading water quality due to seawater infiltration, caused
by the over-pumping that had been taking place.

Rainfall sporadic over Gaza Strip
In
1994, water resources in the Gaza Strip placed under the control of the newly
formed Palestinian Authority and in 1995 the Palestinian Water Authority was
formed and given the mandate for managing water in the Palestinian
Territories. At this time it was widely recognized that there was a
serious environmental problem with the Gaza Aquifer and the water
infrastructure was in a very poor state, with 50 % of water being lost through
leaking pipes.
The coastal aquifer net balance is estimated by Palestinian Water Authority (PWA) in 2011 as follows.The total estimated inflow to Gaza aquifer of 96 – 101 MCM
per year is composed of:
·
Recharge
from precipitation 40-45 MCM per year.
·
Return
flows from leakages 16 MCM per
year.
. Return flows from irrigation 20 MCM per year .
·
Lateral
inflow from Egypt and Israel 15 MCM per year.
The
total estimated outflow of 171 MCM per year reflects:
. Municipal abstraction 89 MCM per year.
. Agricultural abstraction 82 MCM per year.
So the total aquifer deficit is about 70 MCM per
year
This
over abstraction has led to a deterioration of water quality including high levels
of salinization from sea water since the amount pumped from groundwater is much
higher than the natural replenishment of the groundwater aquifer.
If
uncontrolled pumping is allowed to continue the aquifer, which is the primary
source for the Gaza Strip, will become unusable as a source of fresh municipal
water and most agricultural extraction will be too saline for crop irrigation and
threatens the long term sustainability of important water resources which will
also impact upon future generations.
Moreover,
the natural means of water-table replenishment in Gaza has been prevented due
to Israel’s construction of an earthen berm between the Hebron Hills and Gaza
Strip which diverts runoff to its natural destination ( from east to west).
So Gaza
Strip is undergoing a humanitarian crisis which is violations of the human right
to water that have been caused or exacerbated by the sanctions and blockade. It
is in critical situation that requires immediate efforts to improve the water situation
in terms of quality and quantity and a serious water management strategy in the
Gaza Strip. There are only two additional sources of supply. The first is
rainfall collected individually by families on roofs of their houses. The second
source is water purchased from Mekorot four percent of total supply in the Gaza
Strip.
Unlike
the West Bank, the worst problem in the Gaza Strip's water sector is not the
shortage or irregular supply during the summer, but the poor quality of water
flowing through the pipes. The poor condition of the water seriously affects
the quality of life of the local residents and exposes them to severe health
risks.
Border
closures and conflict have now led to severe deterioration of water supply
reliability. Since 2005, water supply has become very intermittent and has
fallen to crisis levels, largely due to the deteriorating political and
security situation which curtails access to power, fuel and spare parts. The
private sector and households are coping through unlicensed wells and small
scale desalination. Following the December 2008/January 2009 military offensive
on Gaza, all conditions have worsened. Damage to infrastructure has had important
consequences for service delivery, and substantial rehabilitation is required.
To
overcome the water deficit in the future, many scenarios and solutions have
been proposed by or to the PWA such as reuse of treated wastewater for
agriculture, imported water from neighboring countries. Transportation of water
from Turkey through water tanker ships was another option. Local alternatives
such as brackish and/or seawater desalination has been focused on, but all of
these options are depending mainly on the socio-economic criteria.
Suggested
solution
Gaza cannot supply itself but must find new
or alternative sources of water, which could be derived from bulk
importation, desalination, and waste water reuse.
The Plan
based on increased supply from local aquifers together with desalination as the
two supply sources, construction of a water carrier from the West Bank and improving
wastewater treatment to allow it to be used for irrigation and managed aquifer
recharge.
The strategies proposed to overcome the problem of water crisis can
be summarized as following:
· Investigate the efficiencies of the existing water supply networks
and identify the existing water supply problems.
· Save water and reduce the rate of waste.
· Develop improved water supplies and cropping systems to better
utilize water resources.
· Develop a legislative system aimed at restricting water extraction.
· Improvements in the efficiency of the water supply distribution
system to lower the leakage.
· The Palestinian water rights should be secured.
· Establish water institutions that are able to govern and manage
water effectively and should be strengthen.
· Implement a combination of water supply and demand measures.
· Agriculture sector should be reform and modernize.
· Protect water quality and enhance the sanitation sector.
· Collect water in storage tanks to be used in non-supply hours.
· Manage water as an economic commodity to achieve efficient use,
encourage conservation and protect water resources.
· Improve wastewater treatment to allow it to be used for irrigation
and managed aquifer recharge.
· Identify illegal connections and convert to legal status.
· Launched public awareness programs about the importance of water
resources.
· Familiarize farmers with and facilitate the use of water saving
techniques.
