Sewage Sludge Treatment Tender: Communauté de Communes des Deux Rives

The Communauté de Communes des Deux Rives has initiated a formal procurement process to manage sewage sludge treatment across its territory in Valence, France. This public health infrastructure project aims to establish a comprehensive system for the collection, transport, and valorization of waste materials.

A Comprehensive Approach to Waste Management

The initiative is divided into five distinct lots to ensure specialized handling of different stages of the treatment process. These include the collection and transport of liquid sludge from various communal stations to a drying unit in Valence d’Agen, as well as the transport of dehydrated sludge to composting sites.

Beyond logistics, the project emphasizes the recovery of materials through co-composting and valorization. The contract includes the essential supply of chemical agents, specifically ferric chloride and polymers, which are critical for the treatment process.

Did You Know? The procurement process is structured into five separate lots, allowing for individual attribution to ensure that each specialized phase of sludge treatment—from chemical supply to composting—is handled efficiently.

Financial and Operational Scope

The total estimated value for these services is 400,000 Euro, excluding VAT. The largest single portion of the budget is allocated to the collection and transport of liquid sludge, estimated at 160,000 Euro.

Operational timelines are set for a start date of September 1, 2026, with an initial duration of 12 months. The agreement allows for up to three renewals, potentially extending the operational framework for several years.

Expert Insight: Samantha Carter notes that the integration of co-composting and the use of flocculating agents like polymers suggest a focus on reducing waste volume and returning nutrients to the environment. Such systemic management is vital for preventing the accumulation of untreated waste in municipal areas.

Future Implications and Next Steps

With the deadline for receiving offers set for July 6, 2026, the community is likely to move toward a selection process based on unit prices. Once the contracts are notified, the execution of these health-critical services may begin immediately.

Following the initial year of implementation, the Communauté de Communes des Deux Rives could choose to renew the contracts up to three times, provided the conditions of the administrative clauses are met. This could lead to a long-term stabilized waste management strategy for the region.
