Faecal Sludge Management

Faecal Sludge Management PDF Author: Linda Strande
Publisher: IWA Publishing
ISBN: 1780404735
Category : Technology & Engineering
Languages : en
Pages : 428

Book Description
It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Description
The Interesting History of Income Tax William J. Federer "The only things certain are death and taxes" - Benjamin Franklin Yet few know America's interesting history of Income Tax, such as: *1787 - U.S. Constitution prohibited a "direct" Federal tax *1862 - "Revenue Tax" on incomes went into effect to finance the Union during the Civil War *1895 - Supreme Court made Income Tax unconstitutional *Woodrow Wilson thought tariffs on imports caused wars, so he worked to replace them with an Income Tax. *1913 - Income Tax was only a 1% tax on the top 1% richest people in America. *1943 - Paycheck Withholding began as an emergency effort to get funds to finance WWII. John F. Kennedy - "Lower rates of taxation will stimulate economic activity and so raise the levels of personal and corporate income as to yield within a few years an increased flow of revenues to the Federal Government." (Annual Budget Message, Jan. 17, 1963) Thomas Jefferson - "It is an encouragement to proceed as we have begun in substituting economy for taxation" (2nd Annual Message, 1802) (176 pages, includes pictures)

How to Design Wastewater Systems for Local Conditions in Developing Countries

How to Design Wastewater Systems for Local Conditions in Developing Countries PDF Author: David M. Robbins
Publisher: IWA Publishing
ISBN: 178040476X
Category : Science
Languages : en
Pages : 148

Book Description
This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
