Hello,
I want to write a proposal about potable water pre cast concrete valve box, to show how advantageous over cast in-situ/ in-place/ valve box/ chamber/, and present it to my office as they are preferring cast in-situ valve box most of the time.
1-Do any one have that proposal or any that can help?
2-What is the best pre cast valve box or design?
2-How to protect ground water leakage to that valve box?
