Among the many challenges of pigging our raw water system into actively operating facilities, dealing with diverted pigging water is the most challenging. When pigging, the receiving water loses all raw water and we are historically diverting to the ponds then off lease until the water is of an acceptable quality for the plant to treat. This drove Class Management and the river operations team to look for solutions in 2021 to both reduce the potential production impacts and improve upon our wasted water (ESG) during pigging activities.
The teams involved are working to understand how to apply Claytek across the full pigging program to drive LPA to zero. Claytek learnings will be applied to the next pig runs in September 2022.
