Cheat sheet how to connect sewage related items in game.

Water and Sewage are optional features and are only available when Water Management is enabled in game settings.

Background

Sewerage refers to the infrastructure that conveys sewage. It encompasses components such as receiving drains, manholes, pumping stations, storm overflows, and screening chambers of the sanitary sewer. Sewerage ends at the entry to a sewage treatment plant or at the point of discharge into the environment. In loose American English usage, the terms "sewerage" and "sewage" are sometimes used interchangeably.

Gameplay

When Water management is enabled in the game settings, the player's republic will begin to generate wastewater. Wastewater must be collected and disposed of. The disposal of wastewater is possible by dumping it in a river or lake or by exporting it to a customs house at a certain fee.

General

Wastewater disposal

Wastewater can be dumped in a river or lake with the help of a sewage discharge. The sewage discharge has three input connections to connect with sewage pipes of any size. Another option is to export the wastewater to a customs house. At the customs house, the player has to pay a fee for exporting.

Wastewater quality

The quality of the wastewater is influenced by the building where the wastewater is being produced. The lower the '% Sewage pollution', the less polluted the wastewater is.

Before the player disposes the wastewater into a river or lake, the player has the ability to treat the wastewater in a sewage treatment plant and turn it into polluted water. The player can control the quality of the water in the sewage treatment plant. In this plant, the wastewater is treated with chemicals to become polluted water, with a maximum water quality of 85%.

Distribution

Wastewater must be collected throughout the republic for buildings to function. This can be done through small, medium, big sewage pipes or with a sewage truck. Big sewage pipes can transport more wastewater over longer distances. Medium sewage pipes can transport less wastewater, and small sewage pipes transport the least. The player can join sewage pipes using sewage switches. Contrary to the name, sewage switches cannot switch on or off wastewater, and are only an interconnection between sewage pipes.

When using a sewage truck, the player must use a sewage loading/unloading station to handle wastewater and the sewage truck must be stationed at the technical services building. The sewage loading/unloading station has multiple sewage connections for pipes of any size.

Wastewater can be collected from buildings by using a sewage tank. The player can connect one sewage pipe, of any size, to a sewage tank. How far away a sewage tank can be placed from a building depends on the terrain height in the environment. If the sewage tank is at a lower height than the building, the distance increases. The larger the difference in height between sewage tank and building the more the distance is increased.

With help of a sewage pump the player can pump wastewater from a lower height to a higher height.

Each worker produces a little under 1 m3 of sewage per day.

How to connect sewage

The image below shows an example of how the player can interconnect sewage-related buildings. This is not a complete overview, but only shows how things can be connected. It is up to the player's imagination and needs to connect everything so as to get a properly working sewer system.

The sewage pumps are optional and the placement of sewage pumps is related to the terrain height in the world. The player places sewage pumps to pump sewer over a hill. When the player daisy chains sewage pumps, very high heights can be overcome, but this comes with high costs.

Notes

• Normal wastewater dynamics apply, meaning gravity-fed disposal works: the wastewater flows downhill, not uphill.
• The sewage pipes in the game require a proper slope due to normal wastewater dynamics.

Buildings related to sewage

Sewage treatment

A sewage treatment plant is a destination where wastewater (water which is no longer fit for its current purpose) moves to once it leaves buildings. The wastewater flows to the treatment plant for processing through sewage pipes, or is delivered by a sewage truck. Ultraviolet lamps are used; they emit UV light that destroys the DNA of bacteria. In addition, chemicals such as chlorine are used to destroy microorganisms.

The default and maximum setting is 85%, this means that water leaving the Water treatment plant is still polluted. When there are no workers at the sewage treatment plant, the plant stops processing wastewater; wastewater collects in the sewage pipes, they clog, and the citizens can get sick.

How far away a sewage tank can be placed from a building depends on the terrain height in the environment. A sewage tank needs to be placed at the same height as a building, but it's better to place the sewage tank at a lower height. The larger the difference in height between sewage tank and building the more the distance is increased. If the sewage tank is at a higher height than the building, the sewage tank will NOT collect Wastewater.
