Guidelines for Source Water Control Options and the Impact of Selected Strategies on Direct Potable Reuse
The research project consisted of three integrated components – a literature compendium, utility case studies, and a Guideline for Source Control and Source Water Treatment Facility Design and Operation. Together, the three documents provide information that facilities can use to implement their own source control programs, especially in cases where a move to potable reuse is in progress or in their future. The Guidelines provide objectives for the development of these programs, as well as design considerations related to advanced water purification and source water treatment facility operational issues that impact IPR/DPR systems.
