Abstract

Purpose – In Mexico, only 19.3 per cent of industrial water is treated (Green-Peace, 2014, pp. 3-4), whereas municipal treatment levels are approximately 50 per cent (CONAGUA, 2014a). This paper aims to focus on how the wastewater treatment plant policy, from a circular economy perspective, is affected by the governance context at the Presa Guadalupe sub-basin. Circular economy can contribute to water innovations that help in improving water quality. However, such benefits are not easily achieved. This case provides an example of the complexity and challenges that the implementation of a circular economy model can face. Design/methodology/approach – Data are collected via semi-structured in-depth interviews with the stakeholders that are members of the Presa Guadalupe Commission. The contextual interaction theory (CIT) is the theoretical basis for this analysis (Boer de and Bressers, 2011; Bressers, 2009). Findings – The findings show that the wastewater treatment plant policy plays an important role in a circular economy model. Some incentives towards a circular economy model are already in place; however, the hurdles of a top-down implementation perspective, low availability of resources, prioritisation of short-term results, lack of enforcement of the “polluter pays”” principle and a linear model of water systems need to be overcome. If Mexico wants to move towards a circular economy model and if the government wants to enforce sustainable development principles, wastewater treatment is a challenge that must be addressed. Originality/value – There are few studies in the circular economy literature that have analysed its implementation under a governance arrangement perspective.

6. Discussion and conclusions

When summarizing the five governance elements of the wastewater treatment plant policy, we can state that the multi-level arrangement is top-down, and the driver of the policy is CONAGUA through its programs and it is followed by the state and municipal government. Even though, all stakeholder should participate in the policy implementation due to the CCPG, the participation is limited to the actors of the CORESE. The CCPG has helped to align multiple perspectives, but the impact has not gone further because they have not been given sufficient legal and financial resources. The only considered perspectives for the wastewater treatment plant policy are the ones from the state and federal government. The instruments to support this policy emphasize infrastructure building over inspections and there is not an integrated perspective that can support water management innovations within a circular economy model. The resources are scarce and those are not well aligned with the responsibilities, for example, the tariffs are sensitive to political interests and politicians prefer short-term results due to their short term in office
