On a 23 ha urban watershed, 10 km East of Paris, rainwater tanks have been installed on 1/3 of the private parcels to prevent stormwater sewer overflows. This paper investigates the macroscopic effect of rainwater harvesting on runoff, and thus the potential of this technique for stormwater source control. The analysis is performed using the SWMM 5 model, calibrated on rainfall- runoff measures from two measurement campaigns, before and after the equipment. The availability of two data-sets allows the authors to point out changes in the catchment's behaviour. The main findings are that: (1) catchment's evolution, mainly caused by individual land-cover modifications, produces non-stationarity of the hydrologic behaviour; (2) the rainwater tanks installed, although they affect the catchment hydrology for usual rain events, are too small and too few to prevent sewer overflows in the case of heavy rain events. © 2012 Copyright Taylor and Francis Group, LLC.

The Water, Environment and Urban Systems Lab (Leesu) has set up an observatory of urban pollutants-OPUR-for the île-de-France region (France) in 1994 This observatory was created in order to improve the knowledge of the sources, characteristics and processes governing the generation and transport of both pollutants and micropollutants in our sewer networks. Since its creation, it has been sponsored by the water sector key actors of the Greater Paris: the Seine-Normandie Water Board, the association for sewage disposal in the Paris conurbation (Siaap), the Hauts-de-Seine and Valde-Marne departments* and the City of Paris. This programme comprises four-year phases. The third phase of the OPUR research programme was launched in 2007 and will be completed within few months. The year 2011 will then be a pivotal year for finalizing the ultimate research efforts under way and reflecting together on the future trends for the OPUR research programme. This paper, which was drafted jointly by the programme partners, is fully in line with these objectives. On the one hand, it aims at taking stock of the functioning of this observatory and drawing lessons from the research efforts deployed within the scope of this scientific programme. On the other hand, it reviews the guidelines as contemplated by the partners for the next four-year phase of this programme.
Dévelopment and implementation of a alert plan 1910 type flood in Val de Marne by the direction des services de lenvironnement et de lassainissement [Elaboration et mise en œuvre dun plan dalerte crue de type 1910 en Val de Marne par la direction des services de lenvironnement et de lassainisssement (DSEA)]

The Val de Marne has an area of vulnerability because of its location at the confluence of the Seine and the Marne. For an exceptional flood of 1910 type, 20 % of its population (1.3 million) and 26 communes of the 47 areas would be impacted. Anticipating such a situation represents a major economic, social and environmental. In sanitation, the General Council of Val de Marne through its Directorate of Services for Environment and Sanitation (DSEA), operates in a regulated assets of nearly 900 km of sewers, 157 automated electromechanical stations managed from a central system (Valerie). This heritage of sanitation would be directly impacted in the event of major flooding, then a program of protection works on the banks and emergency plan to organize the protection of the assets has been achieved. This emergency plan is to organize human and material resources to implement in the alert phase to protect the equipment that they be operational as soon as possible to the recession. To create the reflex response, an annual exercise of formal protection of stations is organized and can thus maintain a level of knowledge and an awareness of risk. © Société Hydrotechnique de France, 2011.

The oral health of drug users is increasingly part of the medical universe of caregivers. For too long, the place of oral health in the good living was very thin. The mouth of a patient interests very few people, and still less the person himself who begins to worry that very late. His entourage has a lot of other reasons for concern and the dentist is infrequently associated to support teams in a global approach to public health, and a fortiori as caregiver.

This article reminds you that, whatever the psychoactive substance in question, it is not one that has repercussions on the oral health of its user. This affects both the tooth, the periodontal and oral mucosa. Drug addicts, especially those engaged in polydrug use, represent the population at the largest risk for oral cancer. Of all the factors, smoking is by far the largest risk. The alcohol has a synergistic effect with the tobacco, so that the combined effect is more than multiplied. Preventing risks of these products is possible through good oral hygiene and lifestyle, preventive care and followed by a regular dentist. Regaining self-esteem, however, should be one of the key dimensions of social reappropriation through his body.
