How would you fix the grade of the cistern on the right side of the house so the water on the top if not channeling into the sill plate/foundation? Is removing the best option?

Buying a new house, and trying to figure out the best way to approach this problem with the cistern on the right side under the HVAC unit. It has allowed water intrusion, which is making it so we have to replace the sill plate. To prevent this in the future, what is the best option to fix the grade on the top? Remove the cistern? Jack it up? Grade the top with concrete? My concern with not removing it is that the crack between the cistern and the house will always allow water thru and trap it, but curious to see what you guys have to say. submitted by /u/slashroot102 [link] [comments]
