Below the house built by my family is sewage passing through the sewage treatment station, but cement pipes are installed. Is feng shui good?

Superstitious, I don't know. From the perspective of environmental protection, I think it is not good, because there are many bacteria and other microorganisms in sewage. Even with cement pipes, microorganisms can still reproduce over time. And if it happens to be a bean curd residue project, the pipeline will break and microorganisms will be scattered into the atmosphere, which is naturally not good for nearby residents. But if the pipeline is under the soil, the impact will be relatively small.
