So I know that if I have a retaining wall, I have to provide proper drainage using weep holes or perforated pipes at the side with the higher fill to reduce the hydrostatic pressure acting against the wall.
But what if the grading is equal on both sides of the wall and there is no hydrostatic pressure buildup. Does drainage need to be taken into consideration or can I just let the water accumulate and soak away into the ground without much to worry about?
I'm working on a pump station where a water tank is situated at a high point in the middle of the site and the ground then slopes down all around it until it reaches the concrete boundary wall. The site is so packed with underground utilities that I can barely fit any catch basins or trench drains if required.
