What You'll Learn
Place industrial areas away from residential areas
When it comes to reducing pollution in Cities: Skylines, one of the most important strategies is to separate industrial areas from residential areas. Here are some detailed tips to achieve this:
Firstly, it is crucial to follow the correct zoning of the city. Divide the city into distinct residential and industrial zones, with a considerable distance between them. This prevents industrial pollution from directly affecting residential neighbourhoods. However, be mindful that residents will commute to the industrial areas for work, so don't place them too far away to avoid long commutes, which can lead to decreased city income.
When designing the layout of your industrial zones, consider dispersing them into smaller clusters with forests or green spaces in between. This natural barrier can help minimize pollution spread and provide a more aesthetically pleasing environment. Additionally, you can draw a district around your industrial zone and specialize it in farming or forestry, further reducing pollution levels.
Another strategy is to utilize offices as a cleaner alternative to traditional industrial buildings. Offices provide pollution-free jobs for citizens with higher education levels. However, keep in mind that your shopping areas will need to import goods if you choose to go this route, as offices don't produce tangible goods.
Lastly, be mindful of wind direction when placing power plants, ensuring they are located away from the city and downwind so that pollution doesn't blow towards residential areas. This can help mitigate air pollution, which is a significant concern in industrialized areas.
By implementing these strategies, you can effectively reduce pollution levels in your city by separating industrial and residential areas while also maintaining a functional and prosperous urban environment.

Use renewable energy sources
To reduce pollution in Cities: Skylines, it is important to use renewable energy sources. Here are some strategies to do so:
Wind Power
Wind turbines are a popular choice for renewable energy in Cities: Skylines. They can be placed almost anywhere, making them easy to scale, and they are also quite efficient and resilient. Wind turbines can be built on maps with mountains or placed in open areas, providing aesthetic value to the city. Building wind turbines can also help unlock the Green Energy achievement in the game.
Solar Power
Solar power plants, including solar updraft towers, are another renewable energy source to consider. Solar power is a clean energy alternative that can contribute to reducing pollution levels in the city.
Geothermal Power
Geothermal power plants tap into the Earth's natural heat to generate electricity. They are considered a "green" energy source and can be used to achieve the Green Energy achievement in the game.
Water Conservation
Implementing water conservation policies can help reduce water pollution. Properly locating water and sewage pumps is crucial. Separating water intake and out-take to different rivers can also help minimize water pollution. Additionally, water recycling plants can be placed to treat sewage and improve water quality.
Industrial Zone Management
To reduce industrial pollution, it is essential to plan the layout of industrial zones carefully. Disperse the zones and place forests or parks between them to act as natural pollution absorbers. Ensure that industrial areas are not located too close to residential areas to prevent air pollution from affecting residents.

Properly locate water and sewage pumps
To properly locate water and sewage pumps in Cities: Skylines, it is important to understand how the water and sewage systems work in the game. Here are some tips to help you properly locate water and sewage pumps:
Understand the Basics
First, it is crucial to know that almost every building in the game requires a water supply to function. Water and sewage pipes are always built together, but separate structures are needed for intake and output. Water pumping stations and water towers draw freshwater from natural bodies of water like rivers and wells, while water drain pipes and water treatment plants handle sewage output.
Place the Water Pumping Station Strategically
When placing your water pumping station, ensure it draws freshwater and not contaminated water, as the latter will make your citizens sick. The pumping station must be connected to a water source at all times and have a water drain pipe. Place the pumping station within reach of the blue radius of the water pipe to ensure adequate water supply and sewage management for your buildings.
Manage Your Budget Efficiently
While you cannot control how much water a single pump or drain can handle, you can adjust your budget to optimize water flow and sewage management. Reducing any budget line to 50% will decrease the service to 25% capacity, so it is advisable to keep the water budget at 100% if possible. Regularly monitor your "Water Availability" and "Sewage Treatment" levels, and if they approach the yellow zone, either boost the budget or add more pipes and drains.
Plan Your Sewage Output
Sewage water is always polluted, so be mindful of where you place your output buildings. Ensure that your output buildings are downstream from the pumps to avoid contaminating the water source. Additionally, consider the land underneath the water pipes to prevent any unwanted interactions between the sewage and the surrounding environment.
By following these tips, you can properly locate water and sewage pumps in Cities: Skylines, ensuring a steady water supply and effective sewage management for your growing city.

Use water recycling plants
While it is not possible to completely eliminate pollution in Cities: Skylines, there are several strategies you can employ to mitigate it. One approach is to utilise water recycling plants, also known as water treatment plants, to reduce water pollution.
Water treatment plants serve as sewage dumping systems, purifying 85% of the pollution in sewage. They are unlocked after achieving the "Big City" milestone. By constructing these plants, you can minimise the environmental impact of your city, particularly when compared to dumping raw sewage into bodies of water.
To effectively utilise water treatment plants, it is recommended to replace drain pipes with these plants. While the animation for the pipes may remain unchanged, indicating pollution, the treatment plants significantly reduce the amount of pollution entering the water. This "go green" approach may cost a bit more, but it is beneficial for the environment.
However, some players have expressed that water treatment plants feel useless in the game. They argue that, unlike in SimCity 4, where these plants had a substantial impact on groundwater pollution and could be built anywhere, in Cities: Skylines, they are restricted to the shoreline and do not seem to affect pollution from water drain pipes. Additionally, water treatment plants cost more, require more energy, and take up more space compared to normal drain pipes.
Despite these sentiments, water treatment plants can still be beneficial. They emit significantly less pollution than straight drain pipes, processing 33% more waste. If the appearance of polluted water bothers you, water treatment plants can improve the aesthetics by reducing the amount of brown water visible in your city.

Plant trees
While some players of Cities: Skylines have noted that planting trees in polluted areas did not reduce pollution, others have found success with this method. One player reported that they managed to grow their city's population to 20,000 while shrinking pollution from 5% to 0% over the course of a game year.
To reduce ground pollution, players can try surrounding industrial zones with trees. This method may require some trial and error, as one player noted that they had to dezone half of a highly polluted area so that the trees could combat the ground pollution without the added pressure of incoming pollution.
Another player reported that they were able to turn an industrial zone into a residential area by first dezoning it, then filling it with trees, and finally, waiting a few months. This player found that, after this process, the zone was "as good as new".
Players can also draw a district around their industrial zone and specialize that district in forestry. This method has been found to minimize pollution. Additionally, players can create a garbage-breathing forest that cycles garbage from landfills to incinerators, with the forest absorbing pollution on every cycle where the incinerators are off.
While planting trees can be an effective strategy for combating ground pollution, it is important to note that the best way to get rid of pollution is to remove the polluting source. Players can do this by relocating industrial areas and power plants away from the city, considering the wind direction to ensure pollution does not blow toward residential areas, and separating water and sewage pumps to prevent sewage from contaminating the water supply.
