Geothermal power plants are a cost-efficient and resilient option for renewable energy. They have a steady output of power and are not influenced by weather conditions. Additionally, they are visually appealing and can blend in with other steam-based power generation methods.

Hydroelectric Power

Hydroelectric power plants are another renewable energy option to consider. While they may not be suitable for every map, they can provide a significant amount of energy if you have the necessary terrain.

Nuclear Power

Nuclear power plants offer a substantial amount of energy with no ground, water, or air pollution. However, they produce a lot of noise and require a significant amount of water for cooling, so be sure to build them away from residential areas.

By utilising these renewable energy sources, you can effectively reduce ground pollution in your city, improving the health and happiness of your citizens and creating a more sustainable future for your virtual community.

Build an Industrial Waste Processing Facility

To reduce ground pollution in Cities: Skylines 2, it is recommended to build an Industrial Waste Processing Facility. This facility is specifically designed to manage and reduce industrial waste, which is a major contributor to ground pollution. Here are some detailed instructions and considerations for building and utilising this facility:

Planning and Placement

When planning your city, it is crucial to divide it into distinct zones, separating residential and industrial areas. Ensure that the industrial area, which includes factories and power plants, is located at a reasonable distance from the residential zone. This separation will help prevent ground pollution from directly affecting your citizens' health and happiness. However, keep in mind the travel distance for workers commuting between these areas.

Building the Facility

The Industrial Waste Processing Facility can be unlocked by acquiring 8 development points in the garbage management development tree. It is a specialised facility dedicated to processing industrial waste. This facility is unique, as only one can be placed on a map. It is a substantial investment, with a monthly cost of $450,000 and a processing capacity of 55.1 tons per month.

Reducing Ground Pollution

The Industrial Waste Processing Facility effectively lowers ground pollution by 15% across your entire city. It collects and processes garbage generated by industrial buildings, reducing the overall pollution levels. This facility is particularly important for managing the environmental impact of industrial zones.

Complementary Strategies

In addition to the Industrial Waste Processing Facility, there are other strategies to further reduce ground pollution:

• Utilise renewable and clean energy sources, such as wind turbines and solar power plants, to minimise pollution from power generation.
• Implement district policies that promote environmentally friendly practices, such as combustion engine bans, heavy traffic bans, and speed bumps, to reduce pollution from traffic.
• Prioritise sewage management by placing sewage treatment plants downstream and water pumping stations upstream to prevent sewage from contaminating your water supply.
• Upgrade your sewage systems when possible to accommodate your expanding city and reduce the risk of groundwater contamination.
• Educate your citizens to promote better waste management practices and encourage recycling, which will reduce the overall amount of waste generated.

By following these guidelines and strategically utilising the Industrial Waste Processing Facility, you can effectively reduce ground pollution in Cities: Skylines 2, creating a healthier and more sustainable environment for your citizens.

Place sewage and water treatment plants downstream

To reduce ground pollution in Cities: Skylines 2, it is crucial to place sewage and water treatment plants downstream. This strategy ensures that the sewage output is directed away from the city's water sources, preventing water contamination and keeping your citizens healthy.

In the game, water pumping stations and sewage treatment plants play a vital role in maintaining a clean water supply for your city. The water pumping station draws water from sources like rivers, lakes, or groundwater, while the sewage treatment plant processes and treats wastewater before disposal.

When placing these structures, it is essential to consider the direction of water flow. By situating the water pumping station upstream and the sewage treatment plant downstream, you can prevent sewage from contaminating your water supply. This setup ensures that your citizens have access to fresh, clean water, which is essential for their health and well-being.

To identify the correct placement, you can refer to the water's surface, which features arrows that indicate the direction of water flow. By placing the water pumping station upstream, you can be confident that the water being drawn is clean and uncontaminated. Conversely, placing the sewage treatment plant downstream ensures that treated sewage is carried away from the water source, reducing the risk of pollution.

Additionally, investing in sewage upgrades is beneficial as your city expands. Upgrades such as the Advanced Filtering System or Chemical Purification can significantly reduce the amount of pollution in treated sewage, making it safer for disposal and minimising the impact on the environment.

In summary, placing sewage and water treatment plants downstream is a critical strategy in Cities: Skylines 2 to reduce ground pollution and maintain a healthy and happy city for your citizens.
