Experts claim that asbestos water pipes are not so harmful, but their replacement is primarily to protect human health and the environment. It is estimated that the investment requires at least 100 million euros, while the state still does not have 750 thousand for the project
Health protection of the population and huge technical and economic losses are officially the reasons why Montenegro has to follow the example of other European countries and replace about 620 kilometers of water pipes, made with a mixture of asbestos fibers and cement.
It is uncertain when the whole work will start because 100 million euros are needed, and currently, there is not even 750 thousand euros for the project development - the research of the Center for Investigative Journalism of Montenegro (CIN-CG) and the weekly Monitor has shown.
Currently, only the residents of Plužine and Petnjica have the privilege of not drinking water from asbestos-cement pipes. Others can only comfort themselves that there is no reliable evidence of the harmful effects of ingesting asbestos fibers. However, inhaling asbestos can cause cancer.
In Montenegro, the ban on placing on the market and use of asbestos fibers was introduced only by the 2016 Law on the Environment. Due to the possible carcinogenic effect, this material was banned in the European Union (EU) in 2005. This regulation allows the use of products containing asbestos fibers, installed or in service before 2005, in the EU until their disposal, i.e. the end of their service life, so many European cities still face the same problem.
Asbestos was widely used in construction between 1950 and the mid-1980s when pipes made of this material and cement were installed in water supply systems in all countries of the former Yugoslavia.
Inhalation of asbestos fibers proven dangerous: Hygiene specialist Dr. Ivana Joksimović from the Institute for Public Health (IPH), who conducts the sanitary analysis of drinking water, explains for CIN-CG/Monitor that asbestos is a naturally occurring fibrous silicate mineral, mostly magnesium and iron. Due to its characteristics - resistance to temperature, stretching, and chemicals, it was used for the production of water pipes during the last century.
Thus, these pipes are still part of the distribution networks of European and world capitals. It is estimated that there are more than 400 kilometers of them in the Belgrade water supply system, and it is similar in Budapest, Barcelona, Sofia, Vienna, Lisbon, Warsaw, Rotterdam…
Harmful health effects of inhaled asbestos particles, as Dr. Joksimović points out, are a consequence of the proven carcinogenic effect.
"However, not all the details regarding the health effects of asbestos intake through drinking water passing through asbestos-cement pipes have been clarified yet. Nevertheless, it is considered that ingesting is far less harmful from the health aspect than the inhalation of asbestos particles ", Joksimović states.
Hydrologist Mihailo Burić told CIN-CG/Monitor that due to erosion or physical damage to the pipes, there is a risk that asbestos fibers can be found in the water: “This is everywhere marked as a health risk and asbestos pipes are phased out from the residential, commercial and industrial piping. Asbestos does not dissolve in water, so there is no danger on that basis." It is not known to Burić if asbestos has been found in our waters.
He also states that chlorination of water carries certain health risks, and those modern systems for water purification use UV rays and ozonation. However, these techniques are still way too expensive for Montenegro.
"Our waters are at the top in the world in terms of primary quality, there is only a bacteriological risk", Buric explicitly stated.
The World Health Organization (WHO) has no guidelines: This is exactly the risk that the Nature and Environment Protection Agency (NEPA) states in its reports every year - the biggest sources of surface and groundwater pollution are municipal wastewater. The latest published report for 2018 states: "In the continental part, the natural water quality at almost all groundwater sources is worsened by predominantly anthropogenic influences and is the result of inadequate sanitary protection and inadequate sanitation of the catchment area." Groundwater in Montenegro provides about 92 percent of the total amount of water to supply settlements.
The World Health Organization has so far not determined the carcinogenicity of asbestos ingested by drinking water, so there are no guidelines on the permitted amount in water. A risk has been recognized for people working on the removal of asbestos pipes because they can inhale particles of this material.
"Asbestos exposure occurs through inhalation of fibers present in the air, most often in the work environment, near factories where asbestos is used, or indoors containing asbestos materials in poor condition. Prolonged exposure can cause lung cancer and other lung diseases ", is stated on the website of the Ministry of Health of Croatia.
The Institute of Public Health 'Batut' in Belgrade reacted to the frequent media reports in Serbia that drinking water flowing through asbestos pipes causes cancer, saying that epidemiological studies on experimental animals and the human population have shown that there are harmful effects on health if asbestos is inhaled, but that there are no harmful effects if ingested with drinking water.
The director of the Croatian Institute of Toxicology, Dr. Franjo Plavšić, also categorically claims that there is no harm to the health of the population, considering that asbestos particles do not dissolve in water. He has stated in the author's article that "asbestos is dangerous only if its fibers are inhaled, while they can’t cause health problems if swallowed."
TWO-THIRDS OF WATER ARE LOST: Pipes containing asbestos, on the other hand, showed shortcomings due to the large loss of water flowing through them. Burić states that the technical and economic motives for replacing these pipes are significant because up to two-thirds of water is lost.
"The question is how realistically the constant losses are shown – according to some the loss is 50 percent, and according to others 70 percent. It is certain that part of the losses is caused by asbestos pipes, because they often burst, unlike new plastic ones ", Burić says.
The Association of Waterworks of Montenegro (AWM), which brings together all Montenegrin water companies, began preparing the project "Replacement of asbestos-cement pipes in the water supply networks of Montenegro" in June 2018. Despite assurances from experts that asbestos pipes are safe, they also indicated in the project's objectives that its replacement "provides health protection to the population", then reduces water losses, increases water security, enormously increases business efficiency, and meets EU requirements, which is in line with the negotiating Chapter 27 – Environment and Climate Change.
The Ministry of Sustainable Development and Tourism (MSDT) explained to CIN-CG/Monitor that the replacement of these pipes is not one of the criteria for closing Chapter 27, in negotiations with the European Union, but that "our country is replacing the remaining asbestos-cement water pipes, primarily to protect human health and the environment”.
COALITION 27 IS WARNING OF WASTE: "The distribution water supply network in most cities consists of asbestos-cement pipes. Disposal of construction waste containing asbestos is not adequately regulated ", it is stated in the Shadow Report of the Coalition 27 (non-government organizations dealing with ecology). They also stated that it is necessary to raise public awareness about the harmfulness of chemicals, handling substances containing asbestos fibers, and handling asbestos waste.
Thanks to the support of the United Nations Development Program (UNDP), in 2019, project tasks were prepared for 21 municipalities, necessary for the development of major projects for the reconstruction of asbestos-cement pipes.
Within the local self-governments, there are 21 city companies for water supply and sewerage with a total of 2,124 employees. Most of them are in Podgorica - over 600.
"Every water supply system in Montenegro has technical and commercial losses. The technical losses are affected by the age and quality of the installed water supply network, and in developed countries, they range from 18 to 22 percent ", Bojan Lazović, the President of the Assembly of the Association of Waterworks of Montenegro, explains.
In addition to the losses recorded by developed countries as well, the specificity of Montenegro is the so-called commercial losses, which is a euphemism of illegal connections and theft.
"Based on the research, we came to the data that water theft accounts for close to 18 percent of total commercial losses, which mostly happens in suburban settlements," Filip Makrid, the executive director of Podgorica's Water and Sewerage Company, explains.
As the most common reason for this type of loss, he states the impossibility of access to the network, because most of it passes through private properties. The solution, according to Lazovic and Makrid, would be to relocate the pipeline under public space, which is a lengthy process that requires a lot of money.
In Herceg Novi, on the way to the consumers, close to 60 percent of water is lost in the summer and about 70 percent in the winter months. The losses are also a consequence of the fact that in Bijelo Polje, for example, the water supply and sewerage network dates from 1961. In Nikšić, the average age of pipes is 35 years, while some parts were installed in 1931.
According to Makrid, Podgorica has smaller losses compared to other municipalities. They managed to reduce them from 61.77 percent in 2010, to the current 48-49 percent.
Despite the reduction, only in Podgorica, due to losses on the network, there is an annual loss of water in the market value of about seven million euros. This calculation was made at the beginning of the year by Zoran Mikić, a member of the Civic Movement United Reform Action (URA) in the Assembly of the Capital, emphasizing that more than 40 million euros of water have been spilled in the last seven years.
Makrid announces that a pilot project to reduce network losses for the areas of Donja and Gornja Gorica, Donji Kokoti, as well as the settlements of Beri, Farmaci, Lekići, and Grbavci, will be completed in the second half of the year.
Asbestos-cement pipes were dominant in the capital's water supply system 15 years ago, but they managed to reduce it from 60 to 18 percent. There are still 136 kilometers of these pipes in Podgorica, and "greater progress is not possible without additional funds, earmarked for this type of work", Makrid says.
"The replacement of dilapidated asbestos-cement pipes is conditioned by the size of the pipeline that is changing. Pipelines with smaller diameters up to 100 millimeters are mostly replaced by polyethylene pipes, and larger diameters with ductile iron or steel pipes,” Markid explains.
The estimated average value for the construction of one meter of water pipe, when replaced, is between 80 and 200 euros. Makrid said that "according to experience, taking into account the urban conditions where the largest number has been located the costs for Podgorica will range from 120 to 180 euros per meter".
MSDT calculates that 170 thousand euros are needed for the preparation of the first phase of the main project, which would replace the 129-kilometer-long pipe.
"These funds need to be planned within the budget of local self-government units, with the support of the capital budget." The deadline for the development of the main projects for the reconstruction of asbestos-cement pipes will be defined after the provision of financial funds, after which the reconstruction will begin," the Ministry has stated.
Assessing that 750,000 euros are needed to make the complete main project for the replacement of about 620 kilometers of pipes, Lazović states that water supply systems are not a unique system like the Electric Power Industry of Montenegro, because the founders and owners are the municipalities.
"Therefore, all investments, including the replacement of dilapidated pipelines, depend on the financial situation of the water supply companies," Lazović explains.
Risky in buildings older than 20 years
At the parliamentary session in October last year, MP of Democratic Front (DF) Branko Radulović asked then Minister of Sustainable Development and Tourism Pavle Radulović if he knew how many asbestos-cement pipes through which water flows in Montenegro were there. "There are 3,000 people who officially get cancer. One thousand five hundred are cured, and one thousand five hundred die. These are IPH's data," Radulović said.
"We are grown people, we can tell fairy tales, but asbestos pipes, roofs, and facades still exist in certain parts of Montenegro. These citizens have been warned. I hope that the state will regulate it through the social program since the citizens cannot finance the replacements themselves. And it’s not just about asbestos. You’ve heard that 16 water companies don’t measure abstraction (water intended for human consumption is water abstracted from a spring and has the quality prescribed for raw water). So, we don't know quantities they abstract" former Minister Pavle Radulović said at the time.
The Nature and Environment Protection Agency issued a Manual on the Handling Materials Containing Asbestos Fibers three years ago. It states that, if the facility was built before 2000, it can be assumed that asbestos is present in it. It is also stated where asbestos was installed in households: in external or partition walls, old panels on roofs, as an insulator in ovens, water heaters, or steam heating boilers…
The media in the region published the statements of experts that in the former SFRY, asbestos was used during the construction of factories, halls, but also entire apartment blocks, health, and school facilities.
There is a well-known case of the asbestos settlement of Bele Vode, in Belgrade, in which apartment owners protested against the frequent occurrence of cancer. After ten years of protests, the entire settlement was relocated, and the demolition of the old one, which began in 2006, was completed in late 2011. Now the new buildings are there.
The cause of the most serious diseases
According to the website of the Croatian Ministry of Health, the main diseases caused by inhalation of asbestos fibers are mesothelioma (a rare type of aggressive and deadly form of cancer), lung cancer (high mortality), and other lung diseases: asbestosis (does not result in mortality, but it is a progressive disease) and diffuse pleural thickening (not life-threatening). It also states data from the World Health Organization that 125 million people worldwide are exposed to asbestos in the workplace: “During 2004, asbestos-related lung cancer, mesothelioma and asbestosis due to asbestos exposure at work caused the deaths of 107,000 people, at 1,523,000, the exposure resulted in health consequences that cause premature death”.
There is no cure for these often deadly diseases caused by asbestos. According to the Slovenian government's website: "Asbestos exposure remains a major problem in removal, demolition and maintenance procedures. Due to the long delay, the disease can appear even after 20 to 40 years after exposure. As asbestos use in Europe increased until the late 1970s, the annual number of malignancies will continue to increase even in those countries that first banned its use. In some Member States, the annual number of asbestos-related diseases will reach its peak only around 2030."
A little chlorine, cloudy and sometimes salty
Hygiene specialist Dr. Ivana Joksimović says that based on the results of analyzes from previous years, it can be said that the quality of drinking water in Montenegro is satisfactory, and that work should be done to preserve it by protecting the source and improving the supply system.
"If we analyze drinking water test results from the city water supply system, we can conclude that the cause of the malfunction was mostly the lack of residual chlorine and increased turbidity (during periods of heavy rainfall). In addition, on some water supply systems, especially in the period of low waters, salinization occurs on the coast ", Joksimović says.
According to the results of microbiological tests of the Institute of Public Health of Montenegro, during 2019, only 2.95 percent of chlorinated water samples did not meet the prescribed health standards, most often due to the increased total number of bacteria and the identification of coliform bacteria.
"A significantly higher percentage of defective samples was registered at measuring points in local, rural water supply systems, which indicates the need for more active monitoring in the coming period," Joksimović points out.
