Abstract:
Much of the pollution from land based activities are directly attributable to wastewater and stormwater. Sound environmental management of these systems is essential.
This document has been prepared by UNEP DTIE IETC as a contribution to the UNEP GPA and is based upon the "Recommendations for Decision-making on Municipal Wastewater: Practical Policy Guidance for Implementing the Global Programme of Action for the Protection of the Marine Environment from Land-based Activities (GPA) on Sewage" (Version 10 November 2000). It is recognized that this latter document is under review and will be replaced by "Guidance on Municipal Wastewater: Practical Guidance for Implementing the Global Programme of Action for the Protection of the Marine Environment from Land-based Activities (GPA) on Sewage" that is being prepared. Therefore, the UNEP DTIE IETC document will be subject to revision following adoption of this latter document by the UNEP GPA. Contents:
