The social effects on health described in France on newborn and 5- to 6-year-old children suggest the existence of a social gradient among the youngest children. The favoured, though unequal, social situation of the department of the Hauts-de-Seine (France), makes it particularly adapted to this study. A survey, conducted in 2010 by the departmental service of maternal and infantile protection (PMI) on a representative sample of 1227 children, who received check-ups in their first or second year of nursery school, reveals a significant increase of overweight (from 4.6 to 16.5%), of language disorders (from 8.3 to 25.3%), of the orientations to specialized consultations (from 20.6 to 36.6%), according to the socioprofessional category of the father or the social affiliation of the children in the following subgroups: children speaking or understanding a foreign language (36.6% of the sample), children schooled in priority educational zones (equivalent to education achievement zones in UK, 13.6%), children with limited social health coverage (13.4%). In contrast, the BCG and hepatitis B vaccinal coverage is systematically higher in these various groups. The multivariate analysis investigates for each health problem its links with these various subgroups, and with previous child care experiences, and PMI medical consultations. This study suggests therefore further prospects for different actions according to health problems or regarding vaccinal strategy. The development of such routine indicators of disadvantage should allow territorial health services to target their actions towards the decrease of social disparities in health and to check a posteriori the efficiency of the public systems, which have been implemented. © 2013 Elsevier Masson SAS.

At the building scale, green roof has demonstrated a positive impact on urban runoff (decrease in the peak discharge and runoff volume). This work aims to study if similar impacts can be observed at a basin scale. It is particularly focused on the possibility to solve some operational issues caused by storm water. For this purpose, a methodology has been proposed. It combines: a method to estimate the maximum roof area that can be covered by green roof, called green roofing potential, and an urban rainfall-runoff model able to simulate the hydrological behaviour of green roof. This methodology was applied to two urban catchments, one affected by flooding and the other one by combined sewage overflow. The results show that green roof can reduce the frequency and the magnitude of such problems depending on the covered roof surface. Combined with other infrastructures, they represent an interesting solution for urban water management. © 2015 Taylor & Francis. Source

The Hauts-de-Seine county has initiated a combined sewer overflow reduction program. A set of static CSOs have been automated and regulated according to local upstream water level conditions. At the beginning, for safety reasons regarding the flooding risks, the regulation rules were set at the same levels as the preceding fixed CSOs. Thanks to recent improvements of the monitoring system and of the sewer model reliability, the level of fixed CSOs and the regulation rules of automated CSOs have been reviewed in order to reduce wet weather overflows to the River Seine and limit flooding risks. In the particular case of the CSOs along the city of Boulogne-Billancourt, important CSO reductions are expected with no significant increased flooding risk. New fixed CSO settings and automated CSO regulation rules have been defined and implemented. The effective sewer network behaviour is now monitored in order to validate theoretically expected results, before evaluating additional overflow reduction possibilities. Source

The use of turbidity measurement plays a major role in the management of the dry weather flows upstream from the Grand open channel in the historical park of the city of Sceaux. This technology suits particularly well since it allows reconciling good representativeness of the water quality and simplicity of process. Source

This paper takes into account the critics of endof-pipe systems for urban water control, under a technological approach, as well as sustainable development expectations. It starts with a presentation of the current means of control -whether public or private- in French cities, and the parts that both solutions play in urban pollution and flood management. Whatever the political and financial difficulties that are actually being faced by the private solutions for rain water drainage for private reuse and more specifically that of the storage/infiltration of runoffs, the aim of this article is to assess the restructuring -whether they are in progress or expected in the future- of the public services in their missions and mode of operation, in relation to all the players, users and inhabitants. urban stormwater management, source control, rainwater harvesting, citizen participation.
