The Filtration Pump is an add-on to the [[Water Pumping Station]]. It allows you to filter contaminated water for use by the city. The downside is that it's very costly and will leave a very small amount of the pollution in the water, though not normally enough to cause complaints.

*If you are in a situation where you're forced to use Filtration Pumps then it would probably be wise to turn off the [[Basic Water Pump]] that comes pre-attached to [[Water Pumping Station]]s.
