The sanitation system
today and tomorrow

SERAMM ensures the
operation and maintenance
Km of waste water and
rain water sewer network.
This network was built in the 19th century and kept being extended throughout the years. It comprises a historic ‘’combined’’ main sewer line which collects and transports the waste and rain water in the town center. A so-called "separate" networks collects and transports the waste and rain water in the peripheral districts by means of specific lines.

Moreover SERAMM monitors 53km of urban rivers (Jarret, Huveaune, Aygalades) and streams that run through 15,000 ha of the territory, as well as 21km of coastline, which are all natural collection points of the rain water not collected by the sewer networks. The characteristics of the territory raises several challenges fot the management, maintenance and modernisation of the networks: high population density, extreme climate conditions such as summer heat waves, violent rainfall events in automn, strong gusts of mistral wind in winter…

All these climatic events induce risks and
have impacts on the operation of the network and on
the urban and coastal environment

Heavy rains degrade the assets due to the sudden increase of the quantities of water to be evacuated, with possible overspills that lead to street floods and untreated water discharge to the sea.
As to the Mistral wind, it drags solid waste and debris likely to encumber the gullies and to end into the sea.
The air and water temperature increases inside the networks and the decrease of the water volume collected by the sanitation system leads to olfactory nuisances in public areas.


professions on the surface and underground.
SERAMM endeavours to operate and maintain this sanitation network in as invisible a way as possible for its users. This necessitates constant monitoring and maintenance to ensure uninterrupted operation (line cleaning, inspections, tightness tests, flow rate control, sand removal…), and on-site repairing actions to ensure constant operation of the systems.

Network
management 3.0?
To improve the network cleaning methods, SERAMM is developing gullies fitted wiht real-time measurement sensors that detect the level of solid wastes trapped. This information is highly valuable for the operators who can more easily detect the locations blocked, target their actions, increase productivity and reduce the arduousness of work.
