All of the city's untreated wastewater were being discharged into the Bogotá river and ultimately the reservoir behind the Muña dam. The community of Muña brought a lawsuit against EAAB, CAR, EMGESA, and the district government for negligence. The Tribunal of the Department of Cundinamarca ultimately decided for the community of Muña and further required the parties to create a review process and action plan to address the grievances brought forth by Muña. The Tribunal reserved the right to force a decision by the defendants if they did not make suitable progress on the mandate. The defendants appealed and the process went under review again. Upon further review, a judge ruled again in favor of Muña and delegated shared responsibilities to CAR, EAAB, and the District. The defendants agreed to the terms set by the court ruling and the prevailing legal document was called ''Convenio 171'' and was signed by all parties in 2007. Convenio 171 calls for CAR to finance and construct the upgrade and expansion of the Salitre WWTP. CAR did this by creating a special account for the Bogotá wastewater program called ''Fondos Para Inversiones Ambientales en Bogotá (FIAB)'' (Funds for environmental investment in Bogotá). EAAB agreed to construct the new interceptors to the forthcoming Canoas WWTP. Multi-stakeholder assistance The World Bank is working with CAR, EAAB, and the Government District to help refine the Sanitation Plan (Plan de Saneamiento) and establish the basis for a long-term program to improve the water ecosystem in the basin. Project cost is US$487 million and the objectives are to transform 68-km of Bogota River into an environmental asset for the Bogota metropolitan region by improving water quality, reducing flood risk, restoring riparian habitats, and creating multifunctional areas along the river that provide an ecological habitat, as well as opportunities for the public use and enjoyment of this urban river. Additionally, the World Bank is offering assistance with an integrated urban water management strategy. The goal is to enable Bogotá to move towards a sustainable approach to improving the Bogotá river and creating an urban environmental asset. Objectives include a model project for urban river recuperation that incorporates water quality improvements, flood control, wetlands, and multifunctional parks. The Inter-American Development Bank (IDB) is planning a US$50 million loan to support CAR in its Bogotá River cleanup efforts. The IDB also contributed a US$1.5 million grant to CAR's environmental control program. An additional US$643,000 was put up by CAR itself. The projects for the basin's protection are to be carried out in multiple stages, the first of which implements an institutional, managerial, financial and operational framework to carry out the cleanup project. With the loan, CAR plans on building aqueducts and increasing potable water supply, drainage systems and wastewater treatment for all 41 municipalities located in the Bogotá river basin. The money may also finance the design, construction and operation of wastewater treatment plants for municipalities that do have them. Category:Geography of Bogotá

Much of the wetlands have been degraded by poor water quality. In response to the degradation of the wetlands, a strong environmental movement has emerged in Bogotá that actively promotes the protection and expansion of wetland areas. In 2006, the Bogotá district government passed a comprehensive wetlands management policy where the district government, EAAB, and CAR work together to protect rivers and wetlands utilizing new regulations and environmental management programs. The basin plan for the Río Bogotá (POMCA) established water quality standards for the river basin until the year 2020, and designates water uses through river segments and sets ambient water quality criteria of approximately 25 pollutants in order to meet the designated uses. Flooding and river restoration Prior to 1950, the Bogotá River meandered through the middle of the basin with wide riparian areas, extensive flood plains, and thriving ecosystmes such as the La Conejera, Juan Amarillo, and Jaboque wetlands. Rapid urbanization has resulted in the channelization of the river, destruction of wetlands and settlements along the river making the river increasingly prone to flooding. In response, CAR has incorporated a flood works program to widen and protect riparian zones, restore the natural meander of the river, and hydraulically connect the river to its flood plains. In one particular component of a World Bank loan (see Multi-stakeholder assistance below) to CAR, EAAB, and the District Government; the Flood Control and Environmental Works project finances a comprehensive river recuperation program that incorporates best practice in urban river restoration. This component consists of improving flood control from an existing 10-25-year return period to a 100-year period, restoring part of the river flood plain, creating and enhancing wetlands and multifunctional parks, and complementing wastewater infrastructure with existing wastewater treatment when possible.

Urban water management in Bogotá, Colombia

Water management in Bogotá, Colombia, a metro area of more than 8 million inhabitants, faces three main challenges: improving the quality of the highly polluted Bogotá River, controlling floods and revitalizing riparian areas along the river. The main public entities in charge of water resources management in Bogotá are the district government, the regional environmental agency Corporación Autónoma Regional (CAR) of the department of Cundinamarca (Cundinamarca Department), and the water and sanitation utility Empresa de Acueducto y Alcantarillado de Bogotá (EAAB). In a rare move, a court mandated that these entities cooperate to improve the river’s quality, a ruling that translated into an agreement signed in 2007 that defined the responsibilities of each entity and forced them to approach the water management challenges in an integrated way. The agreement prepared the ground for the expansion of the Salitre wastewater treatment plant, construction of a new one, widening and protecting riparian zones, restoring the natural meander of the river, and hydraulically connecting the river to its flood plains. These measures are supported by the World Bank and the Inter-American Development Bank.
