Book excerpt: Le diagnostic et la réhabilitation des réseaux d’assainissement urbain demandent une acquisition de données et une modélisation des systèmes et de leurs composants (tronçons de collecteurs et de conduites, etc., ...). Notre travail porte sur l’organisation de ce diagnostic, en étudiant un certain nombre de questions telles que celles-ci : *Quelles informations acquérir pour étudier l’état structurel et l’état fonctionnel d’un parc de collecteurs visitables ? *Comment définir des priorités dans la recherche des informations ? *Quels problèmes de fiabilité peut-on identifier dans le cadre d’une procédure hiérarchisée ? *etc. ... Le mémoire aborde ces différents aspects à travers trois grandes parties. Divisée en trois chapitres (1 à 3), la première partie traite de généralités et expose la problématique. Dans le premier chapitre, pour mieux comprendre l’évolution de leur maintenance à travers les années, nous avons tracé l’histoire des réseaux techniques urbains, en nous appuyant sur quelques résultats d’enquêtes pour illustrer le mauvais état de ces réseaux. Dans le deuxième chapitre, il nous a semblé important de prendre le temps de définir les termes clés qui seront utilisés dans notre travail, tout en proposant que ces définitions soient à la base d’une terminologie commune aux différents acteurs de ce domaine pluridisciplinaire. Dans le troisième chapitre nous présentons les résultats de l’étude bibliographique menée sur les différents outils de reconnaissance, et qui peuvent être utilisés au cours d’une étude diagnostic. Ces outils concernent les trois types de pré-diagnostic : géométrique, hydraulique et d’étanchéité, et géotechnique et hydrogéologique. Dans la deuxième partie nous présentons un schéma conceptuel du diagnostic, en partageant la présentation en quatre chapitres (4 à 7). Au chapitre quatre, nous passons en revue les différentes interactions entre un ouvrage d’assainissement et ses différents environnements, et exposons le comportement des ouvrages dans ces différents contextes. Nous nous intéressons surtout aux moyens de mise en forme des connaissances ainsi formulées, ceci à travers une proposition d’adaptation, au cas des réseaux d’assainissement urbain, du diagramme des causes-conséquences, élaboré dans le domaine de la sûreté industrielle. Pour mener à bien cette mise en forme, nous avons défini deux grandes familles de données : les données de base, nécessaires à un bon diagnostic, sont détaillées au chapitre 5 ; et les données d’orientation utiles pour guider le décideur dans sa démarche le sont au chapitre 6. Pour les unes comme pour les autres, nous avons exposé les différents moyens d’acquisition, suivant le niveau de finesse considéré. Pour mieux illustrer la proposition du schéma conceptuel, nous avons détaillé au chapitre 7 cinq exemples de mécanismes de dégradation relatifs aux ouvrages ovoïdes visitables : affaissement de voûte, ventre, divergence des piédroits, affaissement de radier, et éclatement de l’ouvrage. La troisième et dernière partie présente deux moyens d’application directe du schéma conceptuel proposé : une première à travers l’évaluation de l’état possible de l’ouvrage (chapitre 8), et le deuxième à travers l’étude de son historique et de la vulnérabilité de ses environnements, dans le cadre d’une démarche d’aide à la décision (chapitre 9). Suite à l’application de l’étape 1 de la méthodologie RERAU1 sur 206 tronçons de la Communauté Urbaine de Lyon, nous proposons au chapitre 8 la mise en place de deux types d’indices de présomptions : des "indices de présomptions a priori" évalués à partir de la recherche des facteurs de dégradation présents sur le tronçon considéré, et des "indices de présomptions d’après symptômes" évalués à partir des relevés de défauts réalisés sur le tronçon. Une première utilisation de ces indices est faite à travers l’exploitation des données disponibles sur un parc d’ouvrages de la Communauté Urbaine de Lyon, ainsi que sur un certain nombre d’ouvrage en Ile-de-France. Au chapitre 9 nous présentons les premiers éléments de la mise en place d’un Système de Gestion de la Maintenance des Réseaux d’Assainissement Urbain. Ce système est complété par la présentation des indices de criticité relatifs aux environnements naturels et urbains. Dans la conclusion générale nous dressons un bilan critique de notre travail. Il porte sur le schéma conceptuel proposé, sur les connaissances et les données disponibles, sur les indices de présomptions proposés et leurs premières applications. Des perspectives sont énoncées concernant la poursuite de ces recherches et la mise en oeuvre d’une aide au diagnostic chez les gestionnaires de réseaux d’assainissement urbain.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the advancements made in applied metrology in the field of Urban Drainage and Storm water Management over the past two decades in scientific research as well as in practical applications. Given the broadness of this subject (measuring principles, uncertainty in data, data validation, data storage and communication, design, maintenance and management of monitoring networks, technical details of sensor technology), the focus is on water quantity and a sound metrological basis. The book offers common ground for academics and practitioners when setting up monitoring projects in urban drainage and storm water management. This will enable an easier exchange of results so as to allow for a faster scientific progress in the field. A second, but equally important goal, is to allow practitioners access to scientific developments and gained experience when it comes to monitoring urban drainage and storm water systems. In-depth descriptions of international case studies covering all aspects discussed in the book are presented, along with self-training exercises and codes available for readers on a companion website.

Book excerpt: Roman Villas explores the social structures of the Roman world by analysing the plans of buildings of all sizes from slightly Romanized farms to palaces. The ways in which the rooms are grouped together; how they intercommunicate; and the ways in which individual rooms and the house are approached, reveal various social patterns, which question traditional ideas about the Roman family and household. J. T. Smith argues that virtually all houses were occupied by groups of varying composition, challenging the received wisdom that they were single family houses whose size reflected only the owner's wealth and number of servants. Roman Villas provides a meticulously documented and scholarly examination of the relationship between the living quarters of the Roman and their social and economic development which introduces a new area in Roman studies and a corpus of material for further analysis. The inclusion of almost 500 ground plans, drawn to a uniform scale, allows the reader to compare the similarities and differences between house structure as well as effectively illustrating the arguments.

Book excerpt: This Report presents information on the current state of knowledge of the origins, occurrence, nature and effects of sewer solids for use by engineers, scientists, administrators and water quality planners for the planning, design and operation of sewerage systems. The report addresses both sewer maintenance requirements and environmental protection issues. Increasing environmental standards, coupled with public expectations, have led to stringent water quality standards. In response to this, it has been necessary to develop new methodologies and computer based analytical techniques to model and understand the performance of all aspects of waste water systems. Fundamental to these techniques is the understanding of the way in which sewer solids contribute to the poor performance of wastewater systems and consequential environmental damage. The information presented in this Report about the origins, nature, movement, hydraulic and polluting effects of solids in sewers has enabled strategies and rules to be developed for the management of sewerage systems to minimise the deleterious effects of these solids and associated pollutants.
