What You'll Learn
The impact of Ulaanbaatar's sewage treatment plant
The Tuul River, also known as the Tula River or Queen Tuul, is an 882.8-kilometre-long river in central and northern Mongolia. It is sacred to the Mongols and is critical to the country, with 45% of the country's population living in its basin, which covers only 3.2% of Mongolia's territory. The river is also economically important, with about 68% of Mongolia's GDP produced in the Tuul River basin.
Ulaanbaatar, Mongolia's capital and home to 1.38 million people, is located on the Tuul River. The city's sewage treatment plant has been described as archaic and unable to handle the waste it receives, which has contributed to the river's pollution. The treatment plant was first established in 1964 and last renovated in 1986. It currently has a daily capacity of treating 230,000 cubic meters of sewage. However, due to the increasing population of Ulaanbaatar, the plant is not sufficient to handle the city's waste, leading to the river being polluted with sewage for miles.
To address this issue, a new wastewater treatment plant is being constructed in Ulaanbaatar with the support of the Millennium Challenge Corporation (MCC) and Tetra Tech. The new plant will treat 250,000 cubic meters of sewage in three stages and satisfy 53% of its electricity demand by producing biogas from sludge. It will also feature a biological waste gas treatment system to cleanse odors generated during the treatment process.
The construction of the new treatment plant is an important part of the cooperation between Mongolia and other countries, including China and Oman, which have exempt diplomatic, official, and service passport holders from visa requirements. The project aims to improve wastewater management and protect natural water resources by treating and reusing industrial and household wastewater for irrigation purposes.
In addition to the new treatment plant, Ulaanbaatar is also working to improve water services and upgrade the Ger areas, which currently lack basic infrastructure such as water supply and sanitation systems. These improvements are essential to reducing the pollution of the Tuul River and ensuring that the city's residents have access to clean water.

Effects of mining activity
The Tuul River is a sacred river in Mongolia, revered throughout Central Asian history. It covers a small percentage of the Mongolian territory but is critical to most Mongolians, with nearly half of the country's population living in its basin. The river is also important to the country's nomadic lifestyle and cultural heritage.
However, the Tuul River is facing significant threats due to human activities, particularly mining. Mining activities in Mongolia, especially gold and copper mining, have impacted the water quality in the Tuul River Basin. The river has suffered from increased consumption and pollution due to the growing population in Ulaanbaatar, the country's capital, which is located on the river. The city's outdated sewage treatment plant struggles to handle the increasing waste, leading to the river being polluted with untreated sewage.
Mining has had several detrimental effects on the Tuul River and its surrounding ecosystem:
- Water Quality Degradation: Mining activities introduce various pollutants into the river, including heavy metals, arsenic, and other toxic elements. These contaminants degrade the water quality and pose risks to both environmental and human health.
- Contamination of Sediments: Mining waste often contains high levels of toxic metals such as mercury, arsenic, copper, and lead. These contaminants can settle in the river sediments, leading to long-term pollution and ecological damage.
- Loss of Wildlife: The pollution and degradation of the Tuul River have led to a decline in aquatic wildlife. For example, species like sturgeon have all but disappeared due to the deteriorating water quality.
- Disruption of Macroinvertebrate Communities: Macroinvertebrates, such as insects and crustaceans, play a crucial role in river ecosystems. Mining pollution can disrupt these communities by affecting their diversity and tolerance to pollution, which, in turn, impacts the overall health of the river ecosystem.
- Increased Sedimentation: Mining activities can increase sedimentation rates in rivers, leading to the burial and smothering of aquatic habitats and altering the river's natural flow and ecosystem dynamics.
- Downstream Impacts: Contaminants released into the Tuul River can travel downstream, affecting not only the immediate area but also communities and ecosystems further along the river.

Climate change and grazing pressure
The Tuul River is a sacred river in Mongolia, covering only 3.2% of the country's territory but supporting nearly 45% of the population. The river is critical to most Mongolians, especially those who live a nomadic lifestyle outside the capital city of Ulaanbaatar, which is located on the river. The city relies almost entirely on the Tuul River for its supply of clean drinking water.
However, the river is facing significant threats due to climate change and human activities, including grazing pressure. The changing climate exacerbates the impacts of over-demand, consumption, and pollution from Ulaanbaatar's growing population. The city's sewage treatment plant is archaic and cannot handle the waste it receives, leading to water pollution and a decrease in water quality.
In addition to the impacts of urbanization, climate change is affecting the Tuul River's flow. Studies have shown that precipitation has a stronger influence on the Tuul River flow than temperature. The river's flow is positively correlated with precipitation, with dry periods resulting in decreased river flow due to increased water loss through evapotranspiration. Climate change is expected to increase evapotranspiration in the Tuul River Basin, leading to a projected decline in groundwater levels and water yield.
Grazing pressure is another factor impacting the Tuul River. High grazing pressure, along with heavy mining activity, contributes to the degradation of the river and intensifies the risks of water insecurity for the population dependent on it. The combination of climate change and grazing pressure is exacerbating the threats to the river's health and its ability to meet the needs of both people and nature.
Overall, the Tuul River is facing significant challenges due to climate change and grazing pressure, which are impacting the river's flow, water quality, and ability to support the people and ecosystems that depend on it. Without action, the river will fail to meet the needs of Mongolia and its citizens.

The river's importance to the nomadic lifestyle
The Tuul River, also known as the Tula River or Queen Tuul, is a vital lifeline for the nomadic people of Mongolia. With a length of 882.8 kilometres (549 miles), it winds its way through the country's central and northern regions, playing a pivotal role in sustaining the nomadic way of life.
Nomadic herders, who make up a significant part of Mongolia's population, rely heavily on the river for their livestock. The river provides drinking water for both people and their animals, ensuring the survival of nomadic communities in often harsh and remote environments. The Tuul River watershed is a grassland steppe, ideal for grazing livestock. The importance of the river to these herders cannot be overstated, as their very way of life depends on the availability of water and the health of the grasslands.
The river is also integral to the country's cultural heritage. Sacred to the Mongols, the Tuul River is mentioned in the Secret History of the Mongols (1240 AD) as the location of the "Black Forest of the Tuul River," where the palace of Ong Khan once stood. The river's sacred status is further enhanced by its association with Genghis Khan, who was born and is believed to be buried in the Khentii Mountains, the same mountain range where the Tuul River originates. This rich historical and cultural significance adds to the river's importance in the lives of nomadic Mongols.
Additionally, the Tuul River supports the nomadic lifestyle by facilitating recreation and economic activities. Outside of Ulaanbaatar, the river is a popular destination for tourist camps. It also enables gold and other mining operations, contributing to the economic well-being of the region. The river's economic impact is substantial, with about 68% of Mongolia's GDP produced in the Tuul River basin.
However, the very existence of the Tuul River, and by extension the nomadic lifestyle it supports, is under threat. As Mongolia develops, the river faces increasing pollution, primarily from the country's growing capital city, Ulaanbaatar. The city's outdated sewage treatment facilities struggle to handle the increasing waste, leading to the river being polluted and emitting a putrid smell for miles. Over-demand for water causes the river to run dry for part of the year, and heavy mining activity further damages water quality. Climate change exacerbates these issues, and without intervention, the river may fail to meet the needs of both people and nature.

The river's sacred origins and cultural significance
The Tuul River, also known as the Tula River, is sacred to the Mongols and is generally referred to as the Hatan Tuul or "Queen Tuul". The river is 882.8 kilometres or 549 miles long and covers an area of 49,840 square kilometres or 19,240 square miles. The river originates in the Khan Khentii Strictly Protected Area in the Khentii Mountains, which is located in the Erdene sum of Töv aimag. The Khentii Mountains are significant as they are the birthplace and final resting place of Genghis Khan. The Secret History of the Mongols (1240 AD) mentions a "Black Forest of the Tuul River" where the palace of Ong Khan was located.
The Tuul River has been revered throughout Central Asian history and plays an essential role in the nomadic lifestyle, which is an important part of the cultural heritage of Mongolia. The river is known for its beautiful landscapes and abundant wildlife. The river is typically frozen for almost half of the year and is home to endangered species such as the sturgeon.
The river flows through the southern part of Ulaanbaatar, the capital city of Mongolia, and continues in a western direction in large loops. Ulaanbaatar is home to 1.38 million people and is the largest consumer of water from the Tuul River Basin. The river is critical to most Mongolians, as the basin covers only 3.2% of Mongolia's territory but supports nearly 45% of the country's population.
Unfortunately, the Tuul River is currently facing significant environmental challenges due to pollution and over-consumption. The river suffers from sewage pollution as the city's treatment plant cannot handle the increasing waste, causing the river to turn grey and emit a foul odour for miles. In addition, heavy mining activity, high grazing pressure, and climate change are contributing to the degradation of water quality. The river runs dry for part of the year due to over-demand, and wildlife, including aquatic species, are disappearing.
