Sewage is wastewater that contains a mixture of human waste, food scraps, chemicals, and other pollutants, typically generated from households and industries. It can be harmful to humans by contaminating drinking water sources, leading to waterborne diseases like cholera and dysentery. Additionally, untreated sewage can damage ecosystems, harm aquatic life, and contribute to the spread of pathogens and harmful chemicals in the environment. Proper treatment and management of sewage are essential to mitigate these health and environmental risks.
There is usually a law against running sewage line just into the woods. The raw sewage that comes out into the woods could possible be harmful to animals and humans.
Sewage pipes can be harmful to soil if they leak or break, releasing untreated wastewater and chemicals into the soil. This can lead to contamination of the soil and groundwater, affecting plant growth and biodiversity. Additionally, sewage pipes can introduce pathogens and pollutants into the soil, posing a health risk to humans and wildlife.

Generally sewage is pumped out into the sea rather than a lake. Also a lake will recieve water due to rainfall.
The Mediterranean Sea is polluted because of raw sewage.
The water flows from various sewage systems towards the ocean.
Most water flows through rivers. Sewage is usually treated, by digestion of the organic matter by microorganisms, followed by allowing the sludge to settle before it is discharged to rivers or the sea. When the amount of water exceeds the capability of the sewage plant to treat it, raw sewage is discharged to sea. This can be done safely if a long enough pipe is used, and beaches are closed for a period after the discharge.
