Sanitation and Wastewater Treatment is very important for our environment and our world. These standards of guiding and managing water treatment is greatly beneficial to helping our environment stay as healthy as possible in regards to wastewater management.
Building on the previous edition of M5, which documented the fundamentals of managing a utility from managing operations and maintenance to customer service, from communication to emergency planning, and from safety regulation to financial management, the third edition focuses on the key contemporary topics of vital interest to waterûwastewater managers that go beyond basic books on waterûwastewater utility management. This update is designed to be a road map for navigating the array of resources that are already available in print, in electronic media, at conferences, and with peer utilities.

Comprehensive Transboundary Water Quality Management Agreement with Guidelines for Development of a Management Plan, Standards, and Criteria (ASCE/EWRI 33-09) contains the most current model for comprehensive water quality planning and management of shared water resources. This standard provides a framework which governments can adopt or modify with regard to riparian rights. Governments that seek to manage and preserve shared water resources will find this model and its appendices to be a practical guide. Various aspects of planning and management are analyzed in detail, including administration, water quality and allocation, financing, and dispute resolution. This book can be used on an international scale and in a variety of geopolitical settings. Environmental engineers, infrastructure engineers, and those involved in geopolitics will find this reference especially useful.
