The Concrete Village under the Smart Concrete Systems banner at the Carrefour des Gestions Locales de l'Eau

It will offer a space for discussion and collective reflection in favor of responsible water management, in particular through three conferences dedicated to the quality of sanitation networks and the efficient management of rainwater in a permeable city.

For this edition, the Concrete Village will bring together eight actors from the Concrete Industry: the companies Libaud Concrete, Blard, CRP, Sobemo, Stradal, Robert Thébault SAS, Urvoy and Urvoy Préfa, who will present their industrial concrete solutions for collecting, transporting and manage wastewater treatment and to infiltrate, collect, transport, manage the volumes and quality of rainwater discharges.

It will also host Ethic Environment (bio technology), a start-up specializing in the resolution of industrial and environmental issues CSI Cordes, producer and distributor of sealing systems for concrete pipes, and Trelleborg, one of the main global suppliers of sealing systems for connecting pipes.

Smart Concrete Systems: efficiency and intelligence for water management

By their capacity to embed intelligence, these industrial concrete solutions make it possible to preserve water resources and the natural environment, to optimize designs, to rationalize the production of rainwater and wastewater networks, to control the risks of flooding and runoff, to fight against the waterproofing of urban areas…

Manufactured in an eco-design approach, they make it possible to respond to all the environmental problems of collection, transport, treatment, collection, infiltration, storage, evacuation of water… All projects find their solutions thanks to the technical adaptability to each construction site and the multiplicity of applications, high-tech products and systems: pipes, manholes, segmented collectors, sludge collectors, screens, reservoir pavements, draining coatings, porous pavers, retention basins, ditches-downspouts, retention basins, storage pipes and tunnels, storm and depollution basins, gutters, control structures ...

Smart Concrete Systems are fully in line with the principle of the circular economy, favoring short loops, limiting the production of waste in factories and on site, anticipating the separation capacity of components, recycling and reusing ( Eco-urban drainage pavers made of shell concrete, use of recycled concrete aggregates ...).

As part of the National Recybéton Project, their solutions make it possible to promote the use of materials from deconstructed concrete as constituting new concrete or to use the materials from deconstruction of concrete as a raw material in the production of recycled cements.

The use of BIM, in a collaborative approach, also makes it possible to better rationalize the stages of design, execution and maintenance throughout the life of the works, with generic models registered in the database of products and systems of the Concrete industry.

Highlights of the Concrete Village: three conferences on Wednesday January 30 from 14 p.m. to 16:30 p.m.

Recent normative and regulatory developments concerning the controls of sewerage networks

The decree of July 21, 2015, relating in particular to collective sanitation systems, requires that the work be subject to, before commissioning, a acceptance procedure pronounced by the contracting authority. He specifies that tests aim at ensuring the good execution of the works. In connection with the European standard NF EN 1610 of 2015, the ASTEE guide on the control of new networks, and the revision work of Fascicle 70 title I of the CCTG, this conference will be an opportunity to take stock of the tests to be carried out in terms of compaction, television inspection and tightness.

Rainwater collection and regulation in the permeable city

Town planning and sanitation stakeholders are aware of the imperative need for effective management of the rainwater cycle, which makes it possible to limit water runoff in rainy weather, to control urban pollution and to safeguard water quality. Precast concrete contributes to the implementation of this rainwater management approach within the “permeable city”, by providing solutions for infiltration, storage, regulation, restitution, but also for water use rain. These solutions adapted to the specifics of the projects also make it possible to optimize the phasing of the site and the deadlines, and to meet the requirements of the communities in terms of sustainability.

Waterproof city, feedback from a contracting authority:

Rainwater infiltrates less and less as cities become waterproofed and the volumes of water that run or are collected increase. Faced with these challenges, the place of water, in particular rainwater, in the city is changing and requires specific sanitation solutions to control the risks of flooding and runoff. A client will present feedback, integrating its permeability and waterproofing objectives into the town's development, and the results obtained.
