What Does Reserve Pit Mean?
Reserve pits are storage pits dug near drilling sites for the purpose of holding drilling mud and wastewater from drilling operations. This prevents the harmful additives in the waste water from seeping into the earth and contaminating groundwater. The reserve pits are lined with a special pit liner that prevents contaminants from seeping into the ground.
On completion of drilling activities the reserve pit is fenced to prevent access to wildlife or livestock till the pit is reclaimed.
