Water Pollution In Cities: Skylines: Why And How To Fix It

Water pollution is a common issue in the city-building game Cities: Skylines, often caused by sewage and industrial work. Players must balance their budget and city growth while addressing water pollution to prevent negative consequences such as sickness, complaints, and decreased land value. The game offers two primary strategies to mitigate water pollution: actively reducing pollution using waste-processing structures or removing pollution sources and allowing natural recovery. This introduction aims to explore the challenges and strategies associated with water pollution in Cities: Skylines, providing insights into managing water resources and ensuring the health and well-being of the citizens in the game.

Water pollution is caused by sewage and industrial work

Water pollution is a pressing issue in the popular city-building game Cities: Skylines. In the game, water pollution is primarily caused by sewage, and to a lesser extent, industrial work.

Sewage outlets positioned upstream from water pumping stations can cause water pollution. In the game, players typically use a water pumping station to draw water from a source like a river, cycle it through the city via water pipes, and discharge it back into the river in the form of sewage. If the sewage outlet is upstream from the water pumping station, the water drawn will be polluted, and this can lead to sickness and complaints from citizens, as well as a decrease in land value for nearby zones.

In reality, water pollution is a significant global issue, and it is predominantly caused by sewage and industrial waste. Sewage pollution is a serious problem, threatening both human health and biodiversity. According to the United Nations, more than 80% of the world's wastewater flows back into the environment without proper treatment, and this figure rises to over 95% in some less-developed countries. Sewage can contain harmful contaminants such as nutrients, pathogens, endocrine disruptors, heavy metals, and pharmaceuticals, which can have detrimental effects on both humans and the environment.

Industrial waste is another major contributor to water pollution. The increase in industrialization has led to a rise in industrial waste, which often contains hazardous materials such as heavy metals, pesticides, plastics, and toxic chemicals. When these substances are discharged into water bodies without proper treatment, they can have devastating consequences for the environment and human health. Industrial wastewater can be toxic, reactive, carcinogenic, or ignitable, and it can provide a breeding ground for waterborne pathogens that produce toxins.

To address water pollution in Cities: Skylines, players can either actively reduce pollution by using structures that process and clean waste or remove the sources of pollution and let nature take its course. Similarly, in the real world, effective strategies for combating water pollution include implementing proper wastewater treatment methods and adopting technologies that ensure cleaner production and reduced water consumption.

Water pumping stations should be upstream, with water draining pipes downstream

Water pollution in Cities: Skylines is a common issue that players face, often reaching critical levels before it is addressed. The primary cause of water pollution in the game is sewage, with industrial work being a secondary contributor. Water pumping stations play a crucial role in managing water pollution. These stations draw water from sources like rivers, distribute it through the city via water pipes, and eventually release it back into the water bodies in the form of sewage.

To prevent water pollution, it is essential to strategically place the water pumping stations and sewage outlets. The game itself provides clear guidance through tooltips and building descriptors, recommending that sewage outlets be positioned downstream from the water intake points. This ensures that the polluted water released by the sewage outlets does not mix with the clean water being drawn by the pumping stations.

By placing the water pumping stations upstream and the water draining pipes downstream, you can effectively manage the flow of clean and polluted water. Additionally, it is important to ensure that the water pipes are well-connected to all structures, allowing for proper water supply and sewage disposal. This setup will help prevent water pollution and its associated issues, such as sickness, complaints, and decreased land value in nearby zones.

If you're facing water pollution issues, it is recommended to first identify the source of pollution and address it. Repositioning your water drain pipes to a new area can be a cost-effective solution, as it costs less than constructing new buildings. However, keep in mind that simply moving the drain pipes will relocate the pollution without eliminating it. For a more comprehensive solution, consider investing in upgraded, eco-friendly versions of drain pipes or treatment plants, as they are more efficient and environmentally friendly.

Water towers should be away from polluted areas and industrial buildings

Water towers are an integral part of most municipal water systems, providing consistent and reliable water pressure to residents. They are tall structures that hold a pressurized potable water system, typically storing potable (drinkable) water. Water towers are usually located on high ground to provide enough pressure to send water into the municipal water supply with sufficient force to cater to the area's customers.

In the context of the game Cities: Skylines, water towers play a crucial role in ensuring a clean water supply for your growing city. Water pollution is a common issue in the game, often caused by sewage and industrial activities. To prevent water pollution, it is essential to strategically place water towers away from polluted areas and industrial buildings.

• Prevention of Water Contamination: Water towers should be situated away from polluted areas to prevent the risk of water contamination. Even if the water tower is placed on polluted ground for a short period, the entire tower's water can become polluted.
• Avoiding Health Hazards: In the game, water pollution can lead to sickness among your citizens, negatively impacting their well-being and causing complaints. By keeping water towers away from polluted areas, you can minimize the chances of contaminated drinking water, thereby promoting the health and safety of your citizens.
• Economic Considerations: Water pollution can result in decreased land value for zones near the pollution source. By positioning water towers away from industrial buildings and polluted areas, you can maintain the economic viability of surrounding areas.
• Long-term Cost Savings: While building and maintaining water towers may involve some costs, they are generally cheaper and simpler than water pumping systems in the long run. By investing in well-placed water towers, you can avoid the frequent expenses associated with pumping stations.
• Water Pressure Maintenance: Water towers are designed to maintain consistent water pressure in the public water system, which can be challenging to achieve otherwise. By placing water towers at a distance from polluted areas, you can ensure that water pressure remains stable, providing adequate water supply to your citizens.
• Flexibility in Electricity Supply: In areas with erratic electricity supplies, such as some regions in India, water towers become even more crucial. They can work for a limited time without electricity because they rely on gravity to distribute water through the pipes.
• Reduced Pollution Impact: By keeping water towers away from industrial buildings and polluted areas, you allow for the natural recovery of bodies of water over time. Once the pollution source is removed, clean water will gradually push the dirty water downstream, improving the overall water quality.

In conclusion, positioning water towers away from polluted areas and industrial buildings is a strategic decision that promotes public health, maintains reliable water pressure, and reduces the impact of pollution on the environment and the economy.

Water pipes should be separate from sewage pipes, but cross-contamination is possible

In the game Cities: Skylines, water pollution is a common issue that players face. The primary cause of water pollution in the game is sewage, which can contaminate water sources and lead to problems such as sickness, complaints, and decreased land value. While water pipes should ideally be separate from sewage pipes to prevent cross-contamination, it is possible for them to become cross-contaminated in certain scenarios.

In Cities: Skylines, players typically use a water pumping station to draw water from sources like rivers, cycle it through their city via water pipes, and then release it back into the water in the form of sewage. To avoid providing your citizens with polluted water, it is recommended to place sewage outlets downstream from the water intake points.

However, even with proper planning, cross-contamination between water and sewage pipes can still occur. This can happen due to various factors, such as unprotected piping, backflows, or issues with pumps. Unprotected piping can result from pipe bursts, mould or plant growth, or erosion, often due to poor maintenance. Backflows can also lead to contamination, as they can cause sewage or other contaminants to flow back into the water supply. Additionally, pumps can pull pollution towards them if there are enough of them or if the water isn't moving.

To address water pollution in Cities: Skylines, players have several options. One approach is to actively reduce water pollution by using structures that process and clean up waste, such as water treatment plants. These plants can be placed inland, allowing waste water to be drained back into the ground instead of directly into bodies of water. Another strategy is to remove the sources of pollution and let nature take its course, as water will eventually flow downstream, carrying the pollution with it. Players can also reposition their water drain pipes to less polluted areas or invest in upgraded, eco-friendly pipes or treatment plants when their city's budget allows.

In summary, while it is important to separate water pipes from sewage pipes to prevent cross-contamination, it is still possible for contamination to occur in Cities: Skylines. Proper planning, regular maintenance, and strategic use of water treatment structures can help players manage water pollution and provide their citizens with clean and safe drinking water.

Removing the pollution source will allow the water to clean itself over time

Water pollution in Cities: Skylines is a common issue that players face, often reaching critical levels before it is addressed. The primary cause of water pollution in the game is sewage, with industrial work contributing to a lesser degree.

Water pollution in the game can be addressed in two ways: actively reducing water pollution by using structures that process and clean up waste, or removing the sources of pollution and letting nature take its course. The latter option is more cost-effective and is a good strategy when funds are low or when waiting for the city to grow to a point where upgraded, eco-friendly drain pipes or treatment plants can be invested in.

When the pollution source is removed, the body of water will naturally recover over time. Fresh, clean water will slowly push the dirty water downstream, and the water will eventually flow off the map. This process can be sped up by using pumps to suck up the dirty water and connecting it to an outlet pipe.

It is important to note that water towers and pumps should be moved away from polluted areas and placed upstream, while sewage outlets and water drain pipes should be placed downstream. Additionally, water towers and water storage tanks should not be placed near ground pollution, industrial buildings, or oil resources.

By removing the pollution source and implementing these strategies, the water in Cities: Skylines will gradually clean itself over time.
