Over the years, AEL has spent significant amounts on source reduction projects, external monitoring of plumes, pre-treatment, diversion of effluent, clean and dirty water separation, upgrading the liming station, etc. To ensure compliance with the WUL, a specific compliance management project database has been developed. Key priority initiatives have been identified to facilitate compliance with the conditions of the WUL. The status of the implementation of these initiatives is monitored on a monthly basis by the AECI Executive Committee. Ongoing discussions take place with the Department of Water and Sanitation to ensure that initiatives for the achievement of compliance are acceptable to that Department.
