Executive Summary:
Jordan is an arid to semi-arid country with a land area of approximately 89,342 km2. The
capital of Jordan, Amman is a city of 1.6 million people located in the northwest portion
of the country.
More than 90% of Jordan receives less than 200 mm of rainfall per year Approximately
85% of the total average rainfall in Jordan are lost to evaporation. The remaining rainfall
recharges ground water and contributes to rivers, wadi flows, and reservoirs.
In many Jordanian cities, residents receive water only sporadically, and domestic water
consumption is among the lowest in the world, less than 100 liters/capita/ days.
The most feasible options for reducing the gap between water demand and supply are
improved management of existing water resources, treating wastewater for reuse, and the
rehabilitation of existing water sources.Moreover, Optimal development and utilization of water resources in Jordan and the
institution of associated Water Policy requires the establishment and Implementation of
several integrated resources, information and management systems. The Ministry of
Water and Irrigation is responsible at the national level for
Administering water policy, pollution control and managing water resources.
In fact, with the advent of industrialization and increasing populations, the range of
requirements for water have increased together with greater demands for higher quantity
and quality of water.
Water issues are linked to scarcity of water, which leads to a shift in water planning in
Jordan towards, the use of non-conventional water resources mainly reclaimed
wastewater.Reclaimed domestic wastewater means wastewater that has been used in the home
including toilets, clothes washers, showers and laundry.
Wastewater makes up 99.85% of sewage entering the treatment plants, this important
resource has been considered from the highest level of Jordan government that it has a
full value.
In this paper, I will present a summary about Jordan experience as a developing country
in quality aspects of reclaimed wastewater. The following subjects will be discussed:
wastewater definition, Reclaimed wastewater standard no.893/2002 Means & ways to
protect water resources from the effect of waste water quality deterioration, Physical,
Chemical & Biological properties of wastewater, monitoring activities, treatment plants
efficiencies, and cost of treatment.The paper will be finalized by conclusions and recommendations.

Introduction:
The directorate of Laboratories & Quality through the Division of
Environmental Monitoring and Assessment monitors wastewater all over the
country. Reclaimed wastewater discharged from domestic wastewater treatment
plants is an important component of Jordan water budget About 94.0mcm in the
year 2003 was treated and discharged into various water course or used directly
for irrigation and other intended uses.
Effective protection of the environment requires accurate and detailed
knowledge of existing environment conditions and the ability to detect and
measure the water quality trends.The monitoring of reclaimed wastewater quality involves many distinct activities
to give reliable and usable data.
A monitoring program for domestic wastewater is designed according to
standard no. 893/2002 to collect representative samples through QA and
laboratories accreditation process. In fact, sewage treatment is a multi-stage
process to renovate wastewater before it reenters a body of water, or it is reused.
The goal is to reduce or remove organic matter, Solids, nutrients, disease,
causing organisms and other pollutants from wastewater. Treatment plants
should reduce pollutants in wastewater to a level nature can handle.
What is waste water and why treat it?
Wastewater is not just sewage. All the water used in the home that goes down the
drains or into the sewage collection systems is wastewater. This includes water
from baths, Showers, sinks, dishwashers, washing machines, and toilets.
In combined municipal sewage systems, water from storm drains is also added to
the municipal wastewater sewer system.
The average Jordanian contributes < 100 liters of waste water each day.
Wastewater is about (99.85)% water by weight and is generally referred to
influent as it enters the treatment plant. Domestic wastewater is wastewater that
comes primarily from in dividuals, and doesnt generally include industrialwastewater. Moreover, domestic wastewater in Jordan includes industrial
wastewater from industries connected to the public sewer system.
Wastewater Treatment:
The existing public sector wastewater treatment plants in Jordan are 20 using
different type of treatment systems the systems are divided into trickling filters,
Activated sludge and waste stabilization ponds as shown in table# 1.

A common Set of processes that might be found at a municipal treatment plant
would be:
Preliminary treatment to remove large or hard solids that might clog or
damage other equipment.
Primary settling basins, where the water flows for up to a few hours, to
allow organic suspended matter to settle out or float to the surface andthese settling tank can be rectangular or circular.
Secondary treatment, a type of wastewater treatment used to convert
dissolved and suspended pollutants into a form that can be removed,
producing a relatively highly treated effluent. It utilizes biological
treatment processes follow by settling tanks and will remove
approximately 85% of the BOD and TSS in wastewater. Secondary
treatment for municipal wastewater is the minimum level of treatment
required.
Tertiary treatment: any level of treatment beyond secondary treatment,
which could include filtration, nutrient removal (removal of nitrogen and
phosphoras) and removal of toxic chemicals or metals.
This type of treatment will be used in the new Aqaba treatment plant under
construction.
Jordanian Waste water Quality Standards:
WAJ Follows national legislation that has been issued by the Jordanian
Institute of Standards and Metrology (JSIM) and regulations issued by
the Minister of Water and Irrigation.
The most important standards which wastewater Quality is governed bycan be summarized into:
1. JS 893/2002: This Jordanian standard addresses the standard
requirements and quality control for reclaimed water. It deals with
requirements and properties that domestic wastewater must meet before
being discharged to any receiving body or reused for agriculture or other
intended uses.
2. JS 202/91: This standard deals with the industrial wastewater, which is
produced after being used for industrial purposes. The aim ofimplementing Industrial wastewater monitoring program is to protect the
environment, Water resources, Safeguard health and human safety. In
case of discharging the industrial wastewater or reuse, it should meet and
comply with the above standard that has been renewed.
3. Regulations issued by the Ministry of Water and Irrigation according to
WAJ Law no 18/1988. These regulations deal with industries to be
connected to public sewer systems in order to control releases of
wastewater to sewer pipelines and treatment systems. Each industrial
establishment should get a permission to connect its effluent to sewersystem.

MONITORING ACTIVITIES:
Waste water Monitoring Programs at labs & Water Quality Control
department can be summarized as follows:
A) Domestic wastewater quality monitoring program:
1) This program focuses on monitoring the effluents & influents from the
public Treatment plants, which are operated by WAJ. These treatment
plants are all mainstream technologies that are in common use
throughout the world and would be classified into:
Activated sludge system: Jerash, Salt, Abunussier, Irbid, Douqara,
WadiHasan, Wadi Mousa, and Fuhes Madaba.
Biological contractors: Karak, Baqa, Tafila, and Ajlun.
Stabilization ponds system: As samra, Mafraq, Maan, Aqaba,
WadiEsseer &Ramtha.
2-This program focuses on monitoring the effluents of 20 Treatment plants that
are operated by private sector such as Muta T.P effluent Maeen T.P and
others.
The basic objective of the implementation of this program is to control the
pollution loads and minimize their effects on ground water and surface water,
which can be achieved by having a well design operational system so that its
effluent complies with the Jordan standards to be used for the recommended
application since the water strategy gives a high priority and a full value for the
reclaimed water in the water budget.
A. B) Streams, Wadis, Dams and reservoirs Monitoring Program:
The number of sites to be monitored is about (60).This program is designed to monitor selected sites Such as King Talal dam,
Wadi Arab Dam, and others, which receive direct flow from domestic
wastewater treatment plant. This will measure the pollution loads and effects
on water resources and the environment. The generated water quality data
will be evaluated and decided its suitability for irrigation.
D. Industrial Waste Water Monitoring Program :
This program focuses on monitoring the effluents of more than 175 industrial
establishments. These factories are classified as Follows:
1) Connected Industries to the sewer system: the evaluation is based
on WAJ regulations in order to protect the sewer pipelines and the
treatment plant system.
2) Non-connected industries to the sewer system: the evaluation of
the water quality is based on the Jordanian standard 202 witch is
specified for factories dumping their waste in to the environment.
The over all value of implementing this monitoring program is to protect the
water resources from the toxic materials and pollution loads resulting from the
industrial emissions.
New approach for monitoring mechanism:

6/20
The role of government in monitoring is being reevaluated in Jordan. The old
model government does every thing and pays for every thing, is being replaced
by private sector participation. The countries of USA, Canada and European
counties are using this mechanism. In fact, this means that Jordan government
will focus in setting and enforcing rules and standards.
Waste Water Analysis:
Various types of pollutants are present in domestic wastewater that can be
measured by many different parameters as shown in table (2,3).
The most important class of wastewater contaminants are compounds that react
with oxygen which are characterized by COD,BOD and the second class is
suspended solids .
Wastewater Evaluation:
The generated water quality data will be evaluated according to the reclaimed
wastewater standard no 893/2002.After the evaluation process the directorate issues monthly, quarterly, biannual,
annual reports that show treatment plants violating the standard. The objective
of issuing these reports is to address the problems and asking for correction to
protect and minimize their effects on resources and the anvironment more over,
the water quality differs from treatment to another depending on the operation
conditions and the treatment system.
For example the BOD5 measures the amount of oxygen microorganisms require
in five days to break down sewage. Untreated sewage has a BOD5 ranging from
(475mg/l at WadiArab T.P to 1137 mg/l Madaba T.P that means that it is a
strong sewage comparing it with raw sewage at USA, which ranges from (100-
300) mg/l. Table 4 no.# will show the difference of untreated wastewater
concentration from govern orate to another.
Treatment plants efficiency:
The efficiency of 20 treatment plants as shown in table # 5 measured by BOD5 as
an indicator of removing dissolved organic matter from treated sewage it ranges
from 71% for maan T.P to 99% for Wadi Arab T.P.
The efficiency for the wastewater treatment plants& the operation systems used
in Jordan is shown in figure NO(1,2) for the year2003. The above figures clarify
that the activated sludge is very effective in removing dissolved organic matterand WAJ can rely on it as a first choice and after that the trickling filter. The
historical data show that the wastewater stabilization ponds have a low efficiency
in removing dissolved organic matter. which is clear from figure no .1 reclaimed
wastewater standard 893/2002.
How well are we doing?
WAJ so far has provided the service on sewer and treatment systems.
20 treatment plants exist all over the country working 24 hours a day. The
number of carried out connections is (172133) at the end of the year 2003, 67%
of these connections flow to SAMRA T.P wastewater treatment plants operate at
a critical point of the water cycle, helping nature defend water from excessivepollution.

Treated wastewater quantity:
The wastewater quantity flows to treatment plant plants is about 94.1 MCM for
the year 2003 as shown in table # 6 and it was increased by (6.27%) from the
year 2002(88.6) MCM. More over, 72.5% of wastewater quantity was treated at
Sammra T.P. The quantity of reclaimed water is about (74) MCM for the year2003.In fact, WAJ has a goal of attaining total water reuse by having highly
treated effluent to be used in the required aspects according to Jordan Water
Strategy.
Cost of Treatment:
The treatment cost differs from treatment plant to another, the minimum cost
was (16.2) fils /m3 at Aqaba T.P and the maximum cost was (798.4) fils / m3 for
Wadi Musa table No.7 will show the cost of treatment for 19 T.P for the year
2003.
Conclusions:
1. Water reclamation and reuse water expanded so rapidly in recent year. It
is a clear indication that the highest level of government in Jordan
recognizes the full value of reclaimed water to the over all water resources
of the country.
2. Current reclaimed wastewater standard regulate water reuse and
environmental discharges to ensure optimal performance of the
wastewater treatmentplants.
3. Reclaimed water used for irrigation shall be used with use are controls
that protect the heath and safety of worker and the general public who
may be exposed to the water.
4. Planned reuse programs should be created to stop discharging
wastewater effluent to streams and catchments areas.
5. There is a need for active and collaborative involvement of another
ministries and agencies and public participation to make use of reclaimed
wastewater in different aspects.
6. Reclaimed wastewater monitoring program should be implemented
according to standard 893/2002 from both the regulatory body and theoperational agency.
7. There is a need to conduct research projects based on actual uses of
reclaimed water.
8. Public awareness program should be implemented all over the country to let
the people accept the reuse of reclaimed wastewater in irrigation and other uses.
