The South Detention Vault is the first of three regional stormwater facilities to be constructed in Overlake Village. It detains stormwater that has been treated locally within public rights-of-way and private development areas.

The vault has a total volume of 20 acre feet (about 6.6 million gallons). Park facilities will be constructed on top of the stormwater vault in the future. In the meantime, the property owner will use the area over the vault for parking.
