Project Description
If provided by the financial institution, the Early Warning System Team writes a short summary describing the purported development objective of the project and project components. Review the complete project documentation for a detailed description.

According to the Bank’s website, the project will finance water supply and wastewater schemes from the Promoter's investment programme over the period 2025-2029. The underlying schemes aim to improve the operation of systems and the quality of services provided to municipalities and customers. These include optimising water resource allocation through improved reservoir management and connections between conveyors, investing in energy efficiency to reduce ACOSOL's carbon footprint, advancing digitalisation, rehabilitating ageing wastewater collection and treatment infrastructure, and promoting wastewater reuse.

Water supply investments will focus on the upgrade of interconnections within ACOSOL’s water sources of supply (Ramal Este and Ramal Oeste). It will also improve the operation of the system through the construction of new regulatory storage reservoirs (Cabecera and Ramal Oeste reservoirs), together with the water production capacity increase of Rio Verde Water Treatment Plant. Part of the loan will be also allocated to improve the energy efficiency of Marbella desalination plant, including photovoltaic panels and the preliminary study for a new desalination plant.

Investments in sanitation will focus on the upgrading of aged trunk sewers, currently facing sea water intrusion and preventing the potential use of reclaimed water for the irrigation of golf courses due to high levels of salinity. ACOSOL’s investment plan will also upgrade its WWTPs to align with the requirements of the recast Urban Wastewater Treatment Directive 2024/3019/EU, including energy cogeneration and deodorisation in wastewater and sludge treatment infrastructure. Both components will contribute to alleviate the overexploitation of the aquifers in the Costa del Sol area of Malaga.

Early Warning System Project Analysis
For a project with severe or irreversible impacts to local community and natural resources, the Early Warning System Team may conduct a thorough analysis regarding its potential impacts to human and environmental rights.

According to the Environmental and Social Data Sheet, large parts of the underlying investment programme consist of the upgrade and expansion of networks and facilities in urban and residential areas, with the main environmental impacts being those during construction (noise, dust, traffic, etc) and not normally requiring a full EIA, which is the case of the components to be financed by the Project. The resolution of the competent authority on the need for a simplified environmental impact assessment for the upgrade of wastewater treatment plants and the extension of tertiary treatment is still pending.

Some water conveyors will cross riverbeds protected by the Natura 2000 network, which will be considered when designing the component. It must receive the confirmation from the competent authority that there are no significant effects.

Potential social impacts include the possible disruption of services and traffic, noise and temporary occupation of public and private space, and safety hazards during construction only, common for this type of projects in urban environments, and will be addressed as part of the planning for each sub-operation.

Some components might require the acquisition of private property for public purpose. Once identified, ACOSOL will launch the expropriation procedure according to the national legal framework.

Contact Information
This section aims to support the local communities and local CSO to get to know which stakeholders are involved in a project with their roles and responsibilities. If available, there may be a complaint office for the respective bank which operates independently to receive and determine violations in policy and practice. Independent Accountability Mechanisms receive and respond to complaints. Most Independent Accountability Mechanisms offer two functions for addressing complaints: dispute resolution and compliance review.

No contacts available at the time of disclosure.

ACCOUNTABILITY MECHANISM OF EIB

The EIB Complaints Mechanism is designed to facilitate and handle complaints against the EIB by individuals, organizations or corporations affected by EIB activities. When exercising the right to lodge a complaint against the EIB, any member of the public has access to a two-tier procedure, one internal - the Complaints Mechanism Office - and one external - the European Ombudsman. A complaint can be lodged via a written communication addressed to the Secretary General of the EIB, via email to the dedicated email address: complaints@eib.org, by completing the online complaint form available at the following address: http://www.eib.org/complaints/form via fax or delivered directly to the EIB Complaints Mechanism Division, any EIB local representation office or any EIB staff. For further details, check: http://www.eib.org/attachments/strategies/complaints_mechanism_policy_en.pdf

When dissatisfied with a complaint to the EIB Complaints Mechanism, citizens can then turn towards the European Ombudsman. A memorandum of Understanding has been signed between the EIB and the European Ombudsman establishes that citizens (even outside of the EU if the Ombudsman finds their complaint justified) can turn towards the Ombudsman on issues related to 'maladministration' by the EIB. Note that before going to the Ombudsman, an attempt must be made to resolve the case by contacting the EIB. In addition, the complaint must be made within two years of the date when the facts on which your complaint is based became known to you. You can write to the Ombudsman in any of the languages of the European Union. Additional details, including filing requirements and complaint forms, are available at: http://www.ombudsman.europa.eu/atyourservice/interactiveguide.faces
