Question about foundation drains 3

[cliff234]

I am a structural engineer and I have a question about foundation drains behind basement walls. Where does the water in those drains flow to? As a structural engineer we require that the soil behind basement walls be drained, but I am not sure who designs and documents the drainage systems behind basement walls - and where does that water flow to?

Are there any good articles or information on the internet that would be useful in further understanding the fundamentals of basement wall foundation drains?

Thank you in advance for any insight you can share on this.

I would still design it for fully saturated to tke into account the possibility of pump failure or even a burst watermain causing the pump to not be able to cope with the flow of ground water.
