Urmia Lake Rehabilitation Headquarters Review: How to Manage Water Supply Needed for Lake Urmia Rehabilitation

Urmia Lake Rehabilitation Headquarters Review: How to Manage Water Supply Needed for Lake Urmia Rehabilitation

The first session of a series of specialized meetings to review the performance of Lake Urmia Rehabilitation Headquarters with the focus on how to manage the required water resources, on Tuesday, July 3, hosted by the Office of Sustainability of Amirkabir University and Sharif University of Technology and Lake Urmia Rehabilitation Headquarters was held at Amirkabir University. The panel members of this meeting were:

– Dr. Reza Maknoon (Chairman of the meeting and Chairman of the High Monitoring and Evaluation Committee of Lake Urmia Rehabilitation Headquarters),

– Dr. Mehdi Ahmadi (Secretary of the meeting),

– Dr. Masoud Tajrishi (Director of Planning and Integration Office of Urmia Lake Rehabilitation Headquarters),

– Eng. Mohammad Haj Rasouliha (CEO of Iran Water Resources Management Company),

– Dr. Jamshid Mousavi (Head of Water Resources Working Group of Urmia Lake Rehabilitation Headquarters)

– Eng. Arash Akhavan (Director of Operation Office of Water Supply Facilities of Iran Water Resources Management Company)

The main axes studied in this meeting include reviewing the implemented model of operation of dam reservoirs in the last 4 years, reviewing the status of resources and consumption of reservoirs in the catchment area of Lake Urmia and reviewing different models for predicting inflow and operation of dam reservoirs. At this meeting, Eng. Akhavan first presented a report on the planning process carried out to rehabilitate Lake Urmia, the forecasting model used and the measures taken. Then it was the turn of Dr. Mousavi to present a report on the research and activities carried out to provide an improved model for better management of water resources in the area. Engineer Haj Rasouliha then gave a general explanation about the performance of the headquarters. In the last part of the section related to the evaluation of the headquarters’ performance, Dr. Tajrishi explained the situation of Lake Urmia and then it was the turn of the question and answer section that Dr. Maknoon asked questions from the panel members about the future of the lake and the future plans of the headquarters.

Finally, the main points agreed upon by the panel members included the following sections:

  1. One of the most important factors influencing the revitalization of Lake Urmia are dams; Because among 16 important rivers supplying water to Lake Urmia, a national dam has been built on 8 of them. In addition, for example, studies on Buchan Dam, as the most important dam, show that the release of water from this dam has had a great effect on the level of the lake. Therefore, management and planning for dams in order to rehabilitate the lake is very important.
  2. It is necessary to use a suitable model in order to manage the water of the dams and annual planning for their operation; However, it should be noted that the basic information used in the model has as little error as possible and is based on continuous monitoring and the latest information to be in good agreement with the real situation.
  3. The proposed model should be well adapted to changing predicted conditions; Because the amount of rainfall in recent years has shown that the uncertainty in the forecasts has been high.
  4. To rehabilitate Lake Urmia, managing and improving the operation of dams alone is not enough and saving water consumption in the agricultural sector up to about 40% is essential. Otherwise, it is not possible to revive Lake Urmia.
  5. At present, it seems that there is enough water and knowledge to rehabilitate the lake, and by improving the planning models for the operation of the dams, as well as optimizing water consumption in the agricultural sector, it will be possible to rehabilitate Lake Urmia.
  6. There is no need to form other rehabilitation headquarters to manage other catchment areas and water resources in the country, and the experiences gained for the rehabilitation of Lake Urmia can be used as a suitable program and roadmap for other examples in the country.

Signs inserted in plastic containers

Have you ever wondered what these numbers are engraved on the bottom of plastic containers? If you are careful, letters or numbers, and sometimes both, are usually written in the middle of the recycling logo. If you have not seen it, do not worry, unfortunately, every moment you want, there is so much plastic container around you that you just have to reach out to pick one up.
But the story of these numbers: plastics are divided into 7 groups according to their type. With this knowledge, recyclable plastics, hazardous, low-risk, etc. will be identifiable.

Number 1: PETE or PET, which are the same bottles of mineral water that are relatively safe, but because of its porosity, bacteria can penetrate into the bottle, so I’m sorry to say that it is better not to reuse them. Leave them in the dry waste.

Number 2: HDPE or dense polyethylene. Plastic is safe. It is a dull color. Dishwashing liquid and other detergents are such plastics and are suitable for recycling dishes.

Number 3: PVC, which usually pipes are made of, as well as plastic raw materials that stick to food containers and liquid oil bottles. This type of plastic should never come close to heat when cooking because heat releases chemicals into the PVC and penetrates into the cooking food, causing hormonal disturbances, so use as much as you can. Avoid dishes with this material. Never put the material with the growing plastic in the microwave. In fact, these PVCs are bad and are not easily recycled.

Number 4: LDPE or low-density polyethylene. The same nylon shopping bags. These bags are safe but unfortunately usually non-recyclable.

Number 5: PP or polypropylene. Yogurt dishes and similar dishes that have wide openings. Also straw drinks. They are safe and easily recycled.

Number 6: PS or polystyrene. The same disposable tableware. These containers contain potentially toxic substances, especially when heated. Do not use these containers as much as possible. Most of the time they were non-recyclable.

Number 7: The same famous option of other cases. From computer cases and iPods to food containers. Using this plastic, especially for food, is always your last resort, and this number 7 is usually non-recyclable.

I do not know if you noticed or not, but the worst ones were the nylon bags and disposable containers that are both toxic and difficult to recycle. But unfortunately, these worst ones are also among the most.

Steps of implementing occupational safety and health management system in student dormitories

University and student are the main assets and axes of scientific, cultural and social development of the country and the student dormitory as the second home of the student is of special importance in promoting spiritual vitality, maintaining mental and physical peace, developing thought, character development and increasing the educational quality of students.

For the first time in Iran, design and implementation of safety and health management system under OHSAS18001: 2007 standard in dormitories of Amirkabir University of Technology in order to prevent accidents and protect students’ lives and property, facilitate and improve life in dormitories, develop and implement regulations guiding and transparent criteria were performed with the aim of observing individual and collective rights, strengthening the spirit of responsibility and self-confidence by using students’ opinions, providing health, health and safety.

OHSAS 18001: 2007 has been developed to respond to the urgent need of organizations for a standard of occupational health and safety management system by which they can evaluate and emphasize their management system. This standard is divided into two parts, the first part includes specifications Based on which a certificate is obtained and the second part which is a guide to implement an occupational health and safety management system.

The issues that were considered with the implementation of the dormitory standardization plan and the establishment of a safety and health management system are:

  1. Increasing the safety factor of dormitories
  2. Accident prevention
  3. Identify and evaluate safety and health risks and provide solutions
  4. Control of physical, chemical and biological harmful factors
  5. Measurement of ergonomic factors and reduction of stressors
  6. Noise measurement and control
  7. Lighting measurement and control
  8. Measurement of cold, heat and humidity
  9. Develop and implement emergency response plans (fire, earthquake, etc.) to prepare students for disasters, natural disasters, etc.
  10. Compilation and implementation of periodic safety and health audits in dormitories
  11. Periodic evaluation of the compliance of safety and health in dormitories with international standards
  12. Holding training courses in the field of safety and health and raising the level of information and awareness of students
  13. Promoting the reputation of the university in public and internationally
  14. Providing healthy and effective competition between universities and improving the level of safety and health in dormitories

Benefits of obtaining a safety and health management system certification

  1. Develop a planned and documented approach to health and safety.
  2. A clear safety management structure is created that defines the scope of responsibilities
  3. Awareness and knowledge about health and safety increases.
  4. A safer and healthier living environment is created for students.
  5. The risk of accidents and diseases is reduced.
  6. Time lost due to illness and injuries to students is reduced
  7. Costs to pay damages and possible fines will be reduced.

Implementation steps of safety and health management system based on OHSAS 18001: 2007 standard in Amirkabir University of Technology

Assessing the health-safety status: One of the best possible ways to assess the current situation in an organization is its compliance with one of the world standard models. In this regard, in checking the health-safety status of the dormitories, checklists in accordance with the requirements of OHSAS 18001: 2007, which can cover the relevant purposes, have been used.

System design: When designing a safety and health management system, relevant documentation is done. These documents are in the form of executive procedures, work instructions, regulations, safety and health policy.

Establishment of the system: After the documentation and implementation of the safety and health management system in the dormitories, according to the design, was done. At this stage, the records of the implementation of the system for preparing and measuring harmful pollutants in the dormitory environment were done. Internal audit of the safety and health management system was performed for self-assessment at this stage, and after eliminating the non-compliance of the internal audit, the preparations for certification were provided.

Obtaining certification: At this stage, reputable international certification companies were invited to issue certificates, and after the final audit stage by the certification company, the certification stage was performed and the dormitories of Amirkabir University of Technology in March 2008 succeeded in receiving International certificate OHSAS 18001: 2007.
