5/19/2013 | Bonanza Creek Energy Best Management Practices for Installation of Cement Water Vaults at locations Associated with Shallow Groundwater
The following procedure describes construction practices for setting a partially buried pre-cast cement water vault on locations characterized as containing shallow depth to groundwater.
1) The excavation will first be lined with 4” of clay or other low permeability soil.
2) A 30 mil liner will be installed on top of the low permeability soil. The 30 mil liner will be a contiguous liner which will underlay the entire tank battery.
3) The tank battery / water vault liner will be keyed into a galvanized steel containment ring installed surrounding the tank battery.
4) Sand bedding will be installed to protect the synthetic liner prior to placing equipment in the containment area.
