Waterleave

nounStandard termMining

A legal right allowing a miner to use a watercourse for drainage or water supply.

This historic legal easement grants a mining operation the right to discharge mine water into a local stream or draw from it for processing. Securing this access is critical for managing groundwater inflow and operating wash plants. Without it, a mine cannot legally manage its hydrological footprint.

We finally secured the waterleave, so we can start pumping the lower levels into the creek next week.

Insider tip

Historic deeds often bundle this right with airleave and mineral rights, reflecting the heavy reliance on gravity drainage in early mining.
