  • Proof factsheet 1Aguas del Norte and Caesb decided to start a Water Operators´ Partnership, a not-for-profit peer exchange to support the capacity development in the mentee operators (Aguas del Norte). The initial focus for the WOP was energy efficiency however building on this success, the operators decided to extend their partnership and focus on metering, tariffs, IT systems and wastewater treatment. 

    Representatives from the Compañía Salteña de Agua y Saneamiento (Aguas del Norte) in Argentina and the Companhia de Saneamento Ambiental do Distrito Federal (Caesb) in Brazil met for the first time in 2010 during a workshop organized in Colombia to identify strengths and weaknesses of utilities in the region and look for ways for them to help one another. At the time, the Argentinian utility, in a dry mountainous sector of the country, was struggling to reduce its energy bills, while the Brazilians had some recent good experience in the area.

    Over the initial years, the Argentinian operator saved over 100,000 USD owing to energy efficiency measures and is working on introducing more effective metering and billing methods. The total cost of the initial phase of the partnership was just over 47,000 USD, with 32,000 USD provided by the Inter-American Development Bank and the remaining third covered by the operators themselves.

    Wildener Rodovalho, IT Project leader at Caesb said, "The WOP is very important for our company because we learn other processes, working methods, ways to save money...and for us, it is very nice to be able to talk about our work, to share how we are growing, to help other utilities.¨
    Although the WOP helped Aguas del Norte make important operational changes and cost savings, it also helped the team make the most of existing resources to improve their service. Today, the two operators continue working together.

    BEWOP (Boosting the effectiveness of Water Operators´ Partnerships) is a 5-year research, operational support and outreach initiative aimed at boosting the effectiveness of Water Operators' Partnerships around the world. Launched in September 2013, BEWOP is a collaboration between leading water sector capacity development instituted, UNESCO-IHE, and GWOPA, the organization leading the global WOPs movement. This factsheet is part of a series summarizing WOPs cases being studied in order to draw lessons and guide better practice.

  • Proof factsheet 2The WOP is aimed to strengthen technical and organizational capacity of ONEE through knowledge sharing with SIAAP, besides technical support and training, mostly for water sanitation purposes. Self-facilitated and financed, the WOP progresses at its own pace, in response to the needs of the partners, being the knowledge sharing currently through direct interaction between the respective technical departments.

  • Proof Factsheet 3Partners focused on six priority areas following a dynamic and participatory diagnosis, which resulted in an ambitious one-year work plan. The management of the WOP was informal however followed the initial plan. Classroom and on the job training, frequent remote exchanges and operational assistance visits allowed for the expected objectives to be achieved. This inclusive and novel approach was conductive to rapid change and progress.

The publication explains the demand and markets for sanitation, supply chains for sustainable sanitation, looking back at history, case studies (India, Europe, Bangladesh, Bolivia, Burkina Faso, West Africa), and conclusions for action.

  • imgbatch5 60A rapid response assessment of the central role of wastewater management in sustainable development, addressing wastewater challenges (sewage, industrial and agricultural waste discharge), providing key messages on wastewater production and sanitation, and realizing the opportunities of wastewater (wastewater as a resource, and how to manage wastewater effectively), also through policy recommendations.

  • Employing over 7 600 people in its water department and with 624 treatment centres, the Office National de l’Electricité et de l’Eau Potable (ONEE) provides water to over 13 million people and sanitation services to over 3 million.

    This WOP evolved in two phases, with direct financing by the partners involved. The main activities of the first phase entailed four or five yearly site visits by Moroccan delegations to SIAAP’s operational sites. Experts from the Paris-based operator also travelled to Morocco on several occasions.

    After six years of cooperation, the partners decided to restructure their action around more targeted thematic objectives. Flexible governance of the partnership allowed for informal reorientation from as early as 2008, leading to a new formal agreement being signed in 2009.

    Avec près de 7 600 employés pour sa division Eau et 624 centres opérationnels, l’Office National de l’Electricité et de l’Eau Potable (ONEE) fournit l'eau potable à plus de 13 millions d'habitants et une couverture en assainissement à plus de 3 millions de personnes.

    Ce WOP a évolué en deux phases distinctes, avec un financement direct des partenaires impliqués. Les activités principales de la première période se résument à quatre ou cinq visites par an de délégations marocaines d'une quinzaine de personnes dans les sites d’exploitation du Siaap. Des visites d'experts parisiens au Maroc furent également organisées.

    À la suite des six premières années de coopération, les partenaires ont senti le besoin de restructurer leur action autour d'objectifs thématiques plus ciblés. La flexibilité de la gouvernance a permis une réorientation informelle et spontanée dès 2008 avec une interaction directe entre pairs des laboratoires du Siaap et de l’Onee autour du contrôle de la qualité de l'eau. La signature de la deuxième convention de partenariat a eu lieu en 2009.
