High quality and affordable water, waste reduction and waste-to-resource strategy are key challenges of the circular economy. Singapore has long proven its capacity to use technology to overcome its physical constraints in this area. With more than hundred years of expertise in being partners to cities in environmental management, French companies can deliver innovative services tailor made to Asian cities, with the capacity to bridge water, waste and energy challenges.

Solutions for Energy-Efficient Treatment Facilities
Degrés Bleus: innovative technologies that recover heat from urban wastewater systems to heat buildings economically and ecologically. The use of a heat pump allows the system to be reversible: it can be used for heating or cooling.
Water Network Management and Monitoring
Water Management Systems
RiverBoard®: a complete hydrologic solution combining video long-range cameras and an image processing software, to remotely monitor, forecast and manage water resources (4 in 1: water level, surface velocity, discharge, visual control). Images are captured by a surface-based device which is not submerged, meaning that it continues to function during extreme events such as flooding. This solution is used by Météo-France, the main French producer of meteorological data.
Intelligent water management system that enhances capability to integrate realtime information on water resources and to manage water operations across the entire water supply. It includes geospatial asset management system maps to display location of water incidents, and enhanced situational awareness via voice and video transmission.
OASyS DNA SCADA system: a platform that measures, collects and analyses network data to help operators manage water and wastewater infrastructure. It enables automated control and optimisation of network performance.
Control and management tools that continuously monitor and improve water network performance in real time, through general view of network performance with a user-friendly dashboard, event management and analytics to rapidly detect anomalies and identify risks of failure.
Global decision-making system that ensures optimal and transparent management of storm water and wastewater systems at a glance: weather forecasting, water quality, detailed real-time overview of the collection and treatment infrastructure, rainfall forecasts and real-time calculation of its impact, definition of management strategies.
Water Quality Monitoring
KAPTA™: in-line multiparameter water sensor that monitors the drinking water distribution network in real-time (24/7), with early and rapid warning detection of bacteria and chemical pollutants (sample to results time up to 80% faster than traditional methods).
Online and real-time monitoring systems, coupling hardware and software, to allow immediate detection and action for drinking water treatment plants and distribution networks.
District Cooling Systems
Design/modelling, finance, build, operation and maintenance of cooling networks; know-how in linking the system with waste water for heat exchange.
District systems using local and renewable energy, and generating savings from cogeneration or trigeneration system (cooling, heat, and electricity).
SAMPLE OF OUR KNOW-HOW
- Cooling systems in Paris
Cofely operates the Paris energy district network, the 3rd largest in the world, with the use of 49% of energy generated from household waste to energy recovery and a chilled water network serving 400 consumers; Bachy Soletanche realised special foundations and retaining structures for the construction of an air-conditioning plant under the Palais de Tokyo in Paris, lowering the floor of the existing basement by four metres and building pipes to draw water out of the Seine, while taking account of existing networks in a restricted space.
- Drinking water in Singapore
Veolia designed, built and operated the NEWater plant at Kranji with a capacity of 40,000 m3/day. Steria, Saft Batteries, and Endetec-Veolia provide Public Utilities Board (PUB) respectively with an intelligent water management system, Ni-Cd based batteries for substations, and monitoring sensors for early detection of E. Coli and Total coliforms.
- Hong Kong
Veolia designed, constructed and operates a sewage sludge recovery plant that processes up to 2,000 metric tonnes per day. The site is independent in terms of electricity as the energy produced by the plant exceeds its own needs. A sea water desalination unit produces up to 600 m3 of drinking water per day for the site’s needs. Th e building is integrated into the landscape, with its shape inspired by the sea.
- Cannes, France
Suez Environnement operates the Aquaviva wastewater treatment plant with a capacity of 300,000 inhabitant equivalents. Designed in line with high-quality environmental (HQE) standards, the plant represents a genuine technological and environmental achievement. It is carbon neutral as its own greenhouse gas emissions (i.e. 90% less than the previous facility) are off set using various techniques such as solar panels, wastewater sludge dried onsite and used as natural fertiliser for farming, and water reuse.
Solid Waste Collection and Sorting
Pneumatic Waste Systems
They convey waste by air suction through an underground network of concealed pipes to a central vacuum station. They reduce odours, pest infestations, truck traffic and associated emissions. The fully automated process also reduces manpower requirements and increases productivity. For users, the system is simple, practical and available 24 hours a day.
Operation of a pneumatic waste system that includes collection points with one terminal for household waste and another one for recyclable multi-materials.
Operation of a pneumatic waste system that segregates and transports waste at a speed of 70km/hour to a treatment plant.
Smart and Productive Surface-Based Collection
Market-ready solutions to create smart systems comprising sensing, processing (microcontrollers), wireless connectivity, and energy management. Such systems can be used to connect garbage containers in order to automatically trigger collection only when necessary, thus avoiding overfi lled containers and improving garbage fleet management.
Solution for wireless data collection and transmission at voluntary drop-off points with near real-time remote monitoring of container levels and optimised management and emptying by collection services.
Mobile equipment and onboard computer for waste operators (planning, route optimisation, level of hazard). Management of incentive schemes for residents based on recycling bins equipped with RFID chips.
Traditional refuse collection consists in daily removal of local compactors using a lifting truck and transportation to a central treatment facility. To increase productivity and reduce collection fees, an equipment called Minimatics enables the transfer of compacted waste from small collection trucks to a rear-end loader vehicle, using the power of the grid rather the truck’s engine. With Minimatics a single driver in Singapore collects the waste from up to 20,000 households in a single day, instead of 5,000 with the traditional collection.
Remotely operated sorting is an industrial prototype that improves sorting performance and quality. At the Amiens (France) sorting centre, an additional 6% of household packaging is recovered for recycling compared with manual sorting. Two Veolia patented technologies are combined to sort plastic packaging: TSA2 (auto-adaptive sequential sorting) automatically sorts packaging according to its material and colour; then a sorting operator, sitting in front of a screen showing the image of the sorted waste, touches on the screen the unwanted items that are automatically ejected by a compressed air system (semi-automatic sorting process called I-SORT3RTM). The concept of remote operation could be adapted to suit a range of solutions, from packaging to fibers, industrial waste, hazardous waste and contaminated waste.
Facilities for Waste Treatment and Valorisation
Design, built and operation of biomass plants with direct combustion (heat, electricity or cogeneration) or gasifi cation (for direct substitution of natural gas for industrial applications and for biogas production through methanation process). R&D projects are conducted to improve combustion and to use other resources than wood (e.g. vegetable oils, coffee grounds, sewage sludge).
Operation of waste treatment facilities enabling agronomic, material, energy recovery as well as hazardous waste stabilisation.
