Leakage Testing Standard for C-I-P Concrete Stormwater R/D Vaults
Leakage Testing Standard for C-I-P Concrete Stormwater R/D Vaults
(OP)
Does anyone test cast-in-place concrete stormwater retention/detention vaults for leakage?
Per our state department of transportation standard specifications, catch basins are to be "water tight". Placement of concrete for structures (e.g. large underground stormwater vault)"...shall leave a compact, dense and impervious concrete...".
Making a concrete structure water tight is no easy task and even AWWA standards for water reservoirs allow for some leakage. A stormwater vault is not the same as a water reservoir so those standards seem inappropriate.
