We must address the consequences of both present and future contaminant threats to water catchments if we are to provide action that provide solutions at all levels. The implementation of sensors for monitoring important biological and chemical parameters, through time and space, is the indispensable basis for accurate assessments whilst the deployment of state-of-the-art water treatment technologies for the removal of pollutants will enhance water protection and security. We will develop novel approaches to reduce or prevent pollution detected above at the source via; The development of novel off-grid treatment technologies, for rural and urban areas, to remove pollutants based on ultrafiltration membrane technology and bacterial remediation using bio-reactors.
