During firefighting, water will accumulate without evaporation and become heavily contaminated. Contaminated water after firefighting can harm water sources or seep into the soil, even contaminating groundwater sources. Therefore, contaminated water after firefighting should not be discharged into the environment without control of harmful components to the water source and natural environment. Scientific management and recycling of firefighting water helps reduce the amount of water used during firefighting and protects the environment from pollution.
