The document outlines the Integrated Water and Waste Management Plan for the Yzermyn Underground Coal Mine (YUCM), detailing the infrastructure for sewage treatment, water purification, and the overall water balance simulation to manage process water and discharge.

• The mine will implement a Bio-Mite waste water treatment plant (WWTP) using anaerobic and aerobic processes to treat sewage for up to 300 people onsite. The anaerobic stage reduces the Biochemical Oxygen Demand (BOD) load by up to 40%, and the resulting clarified effluent is discharged to the Pollution Control Dam (PCD).
• A modular water treatment plant will be installed to treat contaminated water and salinity using reverse osmosis, potentially preceded by defused air floatation or ultrafiltration. This plant is intended to remain operational after mine closure to treat decant water.
• The mine's water strategy relies on a Pollution Control Dam (PCD) system to collect all dirty water—including underground pumped water, dirty storm water, and treated sewage—for reuse. This system will be the primary water source during peak production until closure.
• Based on an Integrated Water Balance Simulation Model (IWBSM), the mine expects to treat and discharge approximately 8,900m³/a of excess water into a clean water filter drain to recharge the seep wetland (Wetland system 1).
• Sewage solids will not be stored on site; instead, they will be pumped into honey suckers and transported to a licensed site in Piet Retief every eight to 12 months.
