Integrated Management of Municipal Solid Wastes in Aleppo
The usually followed and uncontrolled method of wastes disposition poses a threat to human health since it causes groundwater contamination and air and soil pollution. Additionally, the population growth has contributed to further complicating this issue. The process of wastes dumping under irregular conditions has a very detrimental effect on the environment.
The first phase or the preliminary study is considered as one of the most important stages of work where a selection of treatment plants sites and landfills is made depending on on-site data and technical and environmental preconditions. The improper choice of sites will increase expenses in the process of transferring these wastes and may also be an obstacle in the future in expanding or developing the site. We have taken gradual programmed steps in selecting sites, taking into consideration the climate of the region, its heritage, its archeological sites, its economic and social circumstances and the demanding necessity for protecting all environmental aspects, especially that most areas of the region suffer from the pre-infection of environmental pollution. Throughout the study stages, treatment centers sites are determined and engineering designs are set for each of the treatment centers proposed.

Integrated Management of Domestic Solid Wastes in the City of Idlib
The project aims at setting a strategy for the disposal of domestic and municipal solid wastes of the city of Idlib from the relay stations, mechanical and biological treatment plants and landfills. The design studies of each of the following are implemented:
• Relay ٍStations:
Relay stations serve areas surrounding the municipal solid wastes treatment plant in the studied area, where municipal solid wastes are transferred from the area of collecting to the wastes treatment center and to the landfill.
• Mechanical Biological Treatment Plant:
The process of building and operating the mechanical treatment plant (the sorting plant) has been implemented in one stage. The process of building and operating the biological treatment plant which transforms organic wastes into organic fertilizers will be implemented through various stages in parallel with the development of the volume of organic wastes. Building the biological treatment plant will be during the first phase so that it is sufficient to fully operate the treatment plant, whereas, subsequent phases are for the expansion of the biological treatment plant so that it accounts for the additional quantities of organic wastes resulting from the increase in the volume of municipal solid wastes and thus the volume of the organic wastes.
• Wastes and Exhausts Landfill:
After being processed, domestic wastes are dumped in considered landfills. Emitted gazes are to be collected and treated in addition to collecting and treating the filtering water. Treatment processes will be carried out in technical, environmental, and, at the same time, economical methods.

Integrated Management of Domestic Solid Wastes in the Province of Quneitera
The project aims at developing a strategy for disposing domestic and municipal solid wastes in the province of Quneietra from the relay stations, the biological and mechanical treatment plants and landfills. The design studies of each of the following are implemented:
• Relay Stations.
• Mechanical Biological Treatment Plant.
• Wastes and Exhausts Landfill.

Integrated Management Study of the Industrial Wastes in the Industrial City of Hessia
The study of integrated management of industrial wastes in the industrial city of Hessia mainly concentrates on methods of mitigation of industrial and domestic wastes through setting the programs and the necessary plans. As a later stage, processes of the separate collection of the recycling materials are studied so that to mitigate the residual wastes which will be processed or disposed in the landfills.
The basic strategy followed in European countries with regard to the management of industrial and domestic wastes is used. This strategy relies on the following principle:
Mitigation of Wastes Amount.
- Separation and recycling of wastes: paper, glass, plastic, metals, wood and organic materials.
- Safe disposal of wastes: landfills or incineration.
- Disposal of hazardous wastes after the separate collecting inside the plant.

The Study of Debris and Rubble in the Province of Homs:
Rubble and debris are generally found in big cities where huge projects are implemented. In small towns and areas, by contrast, there is no information about their amount as they are disposed into the outskirts of public roads. The estimated quantity, generally speaking, is about 50 kg per person per year.
The amount and quality of the rubble is estimated through multiple global references, including the estimates of the studies presented by Trevalor and some of the studies already existing in Syria. In addition, there are the field experiments that have been done to analyze the quality and quantity of rubble in the city of Homs.

Reviewing, by Escorting, the Project of Preparing the Terms of Reference Necessary for the Treatment Plants (Turnkey) of Regional Hubs.
The public company of technical studies has studied the drainage of wastewater basins of the city of al Qsair with the route of Homs greater loop. Treated water is discharged from the treatment plant into the Orontes River within a transferring line of a length of approximately 4.5 km and a diameter of 1 m. The importance of the discharging line stems from the fact that it intersects with Homs greater loop.
The study submitted by the public company of technical studies has to provide appropriate solutions for the disposal of sewage basins of the city of al Qsair with the route of Homs greater loop, especially that Homs greater loop is currently under implementation ; the thing which demands the reviewing of the project and thus putting it into implementation .

Wastewater Master Plan in Homs:
A wastewater facility is responsible for contamination of more than 70% of the surface and groundwater in Homs, as is the situation in all Syrian governorates, in addition to the spread of many diseases such as Leishmaniasis, typhoid fever and hepatitis types, as a result of the use of untreated sewage in watering plants.
The study has shown that the plants implemented in the city are : a central plant serving Homs City which constitutes 40% of the population of the Governorate, four bitmap-plants serving five small population assemblies, of a population of no more than 15000 people, constituting 3% of the treatment plants required for the Governorates which are estimated as /143/ ones.
The study depended on international standards to reduce pollution through the implementation of the project of comprehensive structural studying of wastewater documented digitally according to geographic information system GIS at the Governorate level so that to cover the need to maintain a period of the next thirty years and include documentation, updating and developing of the current wastewater plant and the development of strategies commensurate with hot zones and priorities in sewage treatment. The study aims mainly at:
- Evaluating and documenting the current status in details using the GIS for all the wastewater projects implemented, those under implementation, the prepared studies and those which have not been set into implementation, including the main lines and treatment plants, pumping stations and major estuaries lines for cities and communities.
- Assessment of regional hubs implementation and those under implementation and the ones which have not been set into implementation provided that at least two proposals are presented of these hubs, technical and economic.
- Developing integrated structural study of wastewater projects in the province including:
- Identifying deviations and errors for all the projects that will be evaluated and documented and setting the directive solutions to correct these deviations and errors in the study and in implementation.
- Preparing studies and scheme guidelines for the lines and constructions of the main sewage facilities in areas not studied according to the organizational schemes of the housing assemblies.
- Installing or modifying predetermined treatment plants sites and major estuaries paths to determine the type of treatment and to provide apologetic note to modify or to install the site.
- Assessing the treatment plants implemented.
- Locating treatment plants and major estuaries tracks at the Province level to determine the type of treatment for sites that have not been identified before.

Reviewing the Study of Wastewater and Industrial Sewage Treatment Plant of Hessia
Wastewater and industrial sewage treatment plant of Hessia is studied by the advisory body, the study was reviewed and it was decided that the plant is a central joint plant (biochemical) where the technology of activated sludge / conventional ventilation is adopted. This requires that the sludge resulting from the plant is of two types:
• Chemical Sludge: it needs landfills as it contains heavy metals, a landfill has been selected for this type of sludge in Al Qaryatain.
• Biological Sludge: this can be used as afertilizer in agricultural soils after being treated biologically and reduced of its moisture

The treated water resulting from the plant can be used to irrigate green areas within the industrial city or for irrigating certain agricultural crops in accordance with the Syrian standard specifications adopted.
The study relied on the division of the central station into two stations:
1. The first station (emergency one): a net area of 46.2 acres, treating 5,500 cubic meters per day.
2. The second station (Principal ): a net area of 134.93 acres, and it is implemented in two phases. The avarage abundance of the plant is shown in the following table:

The Study of Water Transfer Line from the Euphrates to the Industrial City in Hessia
The proposed project scheme aims at supplying Forqlus oil refinery and the industrial city in Hessia with water by transferring it from the outlet at the site of Palmyra, along the line of water transfer from the Euphrates to Palmyra, with an abundance of 1.2 m 3 / s / to the out-let of oil refinery then to continue with an abundance of 1 m 3 / s / so that the project en-sures transferring lines and pumping stations from the outlet until the tank of the industrial city. The project consists of the following:
• Water outlet from the Euphrates.
• Water transfer lines.
• Supporting uploading plants along the track.

Implementation of a Treatment Plant for Laboratory Analyses in Aleppo Directorate of Environment
The idea of establishing a treatment plant for the wastewater resulting from the laboratory of environment is an excellent step. As water goes directly to sewage treatment plants, this untreated water which contains chemical, organic compounds and heavy metals will often cause the stop of treatment plants, when the proportion of hazardous materials is high, especially heavy metals. In addition, it will cause high operating costs at the treatment plant and high pollution rate in sediments resulting from the plant. This indicates that we can not use these sediments after treatment in agriculture or for other prposes.
The treatment plant is presented and installed so that it is able to deal with chemical contaminants (heavy metals and their compounds, inorganic and organic compounds) and other compounds that result from the analytical work in the laboratories of the chemical analyses.

Project of Drainage Water Disposal Network in Banias Reservoirs Area
The establishment of a network for drainage discharge in the reservoirs area in Banias is for discharging and separating this water from the channels discharging rainwater of the resrviors surfaces and their currently existing basins and collecting the contaminated water (drainage) in basins of separation and sedimentation and thus returning oil to one of the reservoirs and water to the treatment plant. As a result, clean water is disposed to the exisiting rainwater discharge network and the sediments to be treated in line with laws and regulations and instructions to protect the environment and to prevent pollution in the region and the leaking of oil residue and salt to the sea. This is one of the important environmental priorities to preserve the environment and reduce the high economic costs for treatment of the wastewater resulting from the reservoirs.

The Study Proposed to Solve the Problem of Rain Drainage in Areas of Immersion in Homs City:

The problem of rainwater discharge in areas of immersion in the city of Homs is one of the important and basic problems in rainwater and sewage management . This poses a technical problem during rainfall causing expected storms, especially at the beginning of the rain season, where rain water drainage may play a key role because of having the constraints inside, in addition to the lack of a sufficient number or proper linkage between these rain water drainages and the main sanitary sewer.

Providing Engineering Services for Studying the Relay Stations of Domestic Solid Wastes Resulting from Housing Assemblies in Tartus Province
Problems of domestic wastes disposal have increased in Tartus Province as a result of housing , industrial, and tourist development, so we should develop an integrated management and search for new methods to transfer the domestic wastes of the province.
As a strategy of transferring wastes, priority should be given to the CSS displacement of wastes for a sound environmental policy. In addition, methods of transferring wastes should be developed in some small communities because of the rugged areas of the province, especially in most of the mountainous areas.
