Belarus' Water Sources: Natural Supply And Infrastructure

Belarus has a large supply of water resources, including around 20,800 rivers, 10,800 lakes, 153 water reservoirs, and 1,500 ponds. The country's total renewable water resources are estimated at 58.00 km3/year, with an average annual precipitation of 700 mm. While the majority of Belarusians have access to clean drinking water, there are still areas where residents lack access to safe water sources, relying on contaminated alternative sources. The government has made it a priority to improve access to safe drinking water and wastewater treatment facilities, with projects funded by the World Bank helping to bring clean water to thousands of people.

Belarus's water supply and sanitation project

Belarus has an extensive network of piped water and sanitation, yet 15% of the population still lacks access to them. Eight percent of the country's water supply networks and 5% of the sewerage networks need replacing, and 227 wastewater treatment plants need repairs. Groundwater contamination is a hazard, and drinking water quality is poor due to high iron content.

The World Bank has been funding the Belarus Water Supply and Sanitation Project since 2008, with the goal of providing safe drinking water to the population and constructing adequate wastewater treatment and sanitation facilities. The project has brought about several improvements in water and sanitation infrastructure in the country.

One example of the project's impact is the regional centre of Gorodok, which had wastewater treatment facilities built in the 1950s that were unable to handle the volume of wastewater, resulting in contaminated water being discharged into the Gorozhanka River and the system of lakes that feed the Western Dvina River, which flows into the Baltic Sea. A new wastewater treatment plant has doubled the treatment capacity, allowing the city to treat all its wastewater more effectively and in an environmentally friendly manner, while also reducing electricity consumption.

Another example is the township of Borovukha-3, located just 2 kilometres from Polotsk, the oldest city in Belarus. Prior to the project, residents of Borovukha-3 were unable to access clean water in their apartments and had to travel several kilometres to obtain water from friends or relatives. Now, the township's 3,500 residents are connected to a fully automated system that supplies clean water.

Other improvements funded by the project include the construction and rehabilitation of underground water intake points, pumping stations, water supply networks, treated water reservoirs, and iron removal stations in eleven residential areas. In nine towns, deteriorated sewerage systems and wastewater treatment facilities are being replaced, and monitoring stations and small laboratories to test treated wastewater are being established.

The country's river basins

Belarus is divided into four main river basins: the Dnepr, the Western Dvina, the Neman, and the Western Bug. The country's rivers are shared with its neighbours, with some forming the tributaries of these rivers.

The Dnepr basin covers about 81.5% of Belarus. The Dnepr River rises in the Russian Federation and enters Belarus in the northeast, flowing south and forming a border with Ukraine before entering Ukraine and eventually reaching the Black Sea. The Pripyat River is the largest tributary of the Dnepr within Belarus, rising in Ukraine and flowing east into Ukraine to join the Dnepr.

The Western Dvina basin covers about 10% of the country. The Western Dvina River also rises in Russia and flows into Belarus in the northeast, then heads west into Latvia, where it is called the Daugava and flows into the Baltic Sea.

The Neman basin covers about 6% of the country. Its main source is near the capital, Minsk, in the centre of the country. It flows west into Lithuania, where it is called the Nemunas River and flows into the Baltic Sea. The Vilija River, which rises in Belarus to the north of the Neman, becomes the Neris River when it flows into Lithuania and joins the Nemunas.

The Western Bug basin covers about 2.5% of the country in the southwest. The Bug River rises in Ukraine and forms a border between Ukraine and Poland, then between Belarus and Poland, before entering Poland.

The total renewable surface water resources of Belarus are estimated at 58.00 km3/year, of which 37.2 km3/year are generated within the country. The renewable groundwater resources are estimated at about 18.0 km3/year.

The impact of the Chernobyl nuclear accident

Belarus has an abundance of water resources, with around 20,800 rivers, 10,800 lakes, 153 water reservoirs, and 1,500 ponds. However, the country experienced a devastating impact on its water sources due to the Chernobyl nuclear accident in April 1986. Here are four to six paragraphs detailing the effects of this disaster on Belarus's water:

Radioactive Contamination: The Chernobyl accident released radioactive particles into the environment, and about 70% of the radiation fell on Belarus due to prevailing winds. This contamination affected water sources, including rivers, lakes, and groundwater. The Pripyat River, located near the Chernobyl plant, and the Dnieper River, which flows through Belarus, were particularly affected.

Agricultural Impact: About 20% of Belarus's agricultural land was contaminated by the radiation, including the southern and southeastern Polesye region, known for its marshy terrain. This contamination disrupted farming activities and affected water sources used for irrigation.

Evacuation and Resettlement: The Chernobyl accident led to the evacuation of thousands of people from the affected areas in Belarus, Ukraine, and Russia. Resettlement efforts have been ongoing, and some areas remain restricted due to radiation concerns.

Health Effects: The radiation exposure resulted in acute radiation syndrome among firefighters, plant workers, and those exposed to the initial radiation release. The long-term health effects included an increased incidence of thyroid cancer, particularly in children and adolescents. Other health issues, such as gastrointestinal problems, headaches, and radiation-induced cataracts, were also reported.

Environmental Impact: The radiation affected plant and animal life in and around the exclusion zone. Invertebrate populations decreased, and animals living in contaminated areas developed side effects due to initial radiation levels. The radiation also impacted lakes and rivers, increasing the levels of radioactive nuclides in the water bodies.

Water Management Challenges: The accident highlighted the importance of effective water management in Belarus. The country had to address issues related to water supply, quality, and distribution. There were concerns about the concentration of radio nuclides in watersheds in the Dnieper and Pripyat provinces, as well as the potential reduction in runoff during summers.

Water resources per capita

Belarus has a total renewable water resource of 128.3 billion cubic metres per year, which equates to 6,115 cubic metres per person per year. This is higher than the per capita water resources available in England, the Netherlands, and Ukraine, but lower than in Norway and Russia.

Belarus has a total area of 207,600 square kilometres and is bordered by Russia to the northeast and east, Ukraine to the southeast and south, Poland to the southwest, and Lithuania and Latvia to the northwest. The country can be divided into four main river basins: the Dnepr, Western Dvina, Neman, and Western Bug basins, which cover about 81.5%, 10%, 6%, and 2.5% of the country, respectively.

Belarus has approximately 20,800 rivers, 10,800 lakes, 153 water reservoirs, and 1,500 ponds. The total length of the rivers is 90,600 kilometres, and they collect, on average, 55% and 45% of the accumulated river runoff in the Black Sea and Baltic Sea basins, respectively. The longest rivers often collect a portion of their runoff outside the country, including in Russia, Ukraine, and Poland.

The average supply of locally generated water in Belarus is 3,600 cubic metres, including 1,400 cubic metres of groundwater. However, the distribution and quality of water resources are uneven across the country, with varying levels of agricultural and industrial production and water needs.

Belarus has an extensive network of piped water and sanitation, but about 15% of the population lacks access to them. The government has made it a priority to improve access to safe drinking water and to build and upgrade wastewater treatment and sanitation facilities.

Groundwater contamination

Belarus has a sufficient supply of water to meet its current and future consumption needs. The country has around 20,800 rivers, 10,800 lakes, 153 water reservoirs, and 1,500 ponds. The average supply of locally generated water in Belarus is 3,600 m3, including 1,400 m3 of groundwater.

However, one of the main challenges facing Belarus's water resources is groundwater contamination. The Chernobyl nuclear disaster, which occurred in April 1986, heavily affected Belarus. About 20% of the country's agricultural land is estimated to be contaminated, including almost all the drained area in the southern and southeastern Polesye region. The radioactive fallout from the accident resulted in the contamination of water sources, particularly in the areas close to the Pripyat River.

The impact of the Chernobyl accident on groundwater contamination was significant. Radioactive isotopes, such as iodine-131, caesium-134, caesium-137, and strontium-90, were released into the environment and affected water sources. These isotopes have varying half-lives, with iodine-131 having a short half-life of 8 days, while caesium-137 has a longer half-life of 30 years. The contamination of groundwater led to increased radiation levels in the affected areas.

To address the groundwater contamination, various measures have been implemented. The Belarusian government has invested in water treatment and purification technologies to remove radioactive contaminants from water sources. Additionally, the construction of underground water reservoirs in certain sections of the country has been proposed to regulate the water regime and ensure a stable water supply to the population.

The consequences of the Chernobyl accident on groundwater contamination in Belarus are long-lasting, and the full extent of its impact may not be fully understood for decades. However, the Belarusian government and international organizations continue to work towards mitigating the effects of groundwater contamination and ensuring safe and sustainable water resources for the country.
