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, and the water and sanitation utility Empresa de Acueducto y Alcantarillado de Bogotá (EAAB).
Tributary rivers form valleys where villages lie and whose economy is based on agriculture, livestock, and artisan production.
Throughout the year, the days are mild and cool while nights can get moderately cold due to calm winds blowing in the evening.
[3] These systems were viewed as separate and the management strategy did not account for treatment facilities, local streams, and overall water quality within them.
These developments in the Bogotá water management system offer multiple opportunities to incorporate integrated methodologies both now and in the future.
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.
Objectives include a model project for urban river recuperation that incorporates water quality improvements, flood control, wetlands, and multifunctional parks.
[6] The Inter-American Development Bank (IDB) is planning a US$50 million loan to support CAR in its Bogotá River cleanup efforts.
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.
Approximately 26,000,000,000 cubic metres (9.2×1011 cu ft) (BCM) is contained in the Guadalupe aquifer representing about 30 times the amount of water stored in all the reservoirs of the city.
[10] The population of Bogotá consumes 100 to 200 litres per day (0.25 to 0.51 imp gal/ks) per capita which is generally accepted to be an adequate amount for drinking, bathing, sanitation, and cooking.
In the early 1990s, however, the municipal government changed course and decided to pursue 3 medium-sized wastewater treatment plants, one for each of the three sub-catchments (introduced in the previous section) in Bogotá.
In 1994, the city entered into a build-operate-transfer (BOT) concession contract with a French consortium for a 4 m3/s primary WWTP called Salitre, which is located in the northern part of Bogotá.
Bogotá is a center for printing and publishing, the national telecommunications network, the largest industrial facilities in the country.
Bogotá also houses the central governmental institutions and military headquarters, which represent another major component of the city's economy.
[16] A separate UN-HABITAT report from 2003 describes three types of slums in Bogotá: inner-city, those lying on the perimeter, and squatter settlements.
[17] Additional data by UN-HABITAT shows that wealth is very unevenly distributed and that pockets of poverty exist in Bogotá that are poorer than the poorest regions of the country as a whole.
In December 2004, the Department of Planning (Departamento Nacional de Planeación, DNP) issued a strategic planning document for the Bogotá River calling for an upgrade and expansion of the Salitre WWTP to a capacity of 8 cubic metres per second (280 cu ft/s) to address a portion of the remaining 80% of untreated wastewater.
The plan also calls for the construction of a larger primary plant with a 14 cubic metres per second (490 cu ft/s) treatment capacity to be located downstream of Bogotá.
[3] In the lower basin of the city, more untreated wastewater is flushed into the Bogotá River just a few kilometers upstream of the Tequendama Falls before it is then transferred to the Muña Reservoir for hydroelectric generation.
EAAB is financing a project to include the construction of new interceptors on the Salitre and Fucha rivers to transport wastewater to a new WWTP with capacity of 8 m3/s.
These two national policies have been instrumental to support the recent increase of wastewater programs in large cities in Colombia.
This predicted urbanization will continue to exert pressure on the infrastructures, institutions, and water resource management mechanisms that are in place.
All of the housing built by new residents and the subsequent water infrastructure to support a growing population has the effect of reducing impermeable surfaces, thus adding to another one the challenges Bogotá is facing, flood and stormwater control.
[3] Prior to 1950, the Bogotá River meandered through the middle of the basin with wide riparian areas, extensive flood plains, and thriving ecosystems such as the La Conejera, Juan Amarillo, and Jaboque wetlands.
[5] The water company EAAB is actively involved in a participatory program of ecological recovery of the wetlands alongside the river.
These goals are to be met through the development of new lines of action and support from working in collaboration with the District Secretary of Environment, environmental organizations, and other government players.
Specific ecosystem services provided by the wetlands that will be attained include; flood control, stabilization of biogeochemical cycles, carbon sequestration and diversification of aquatic habitats and wildlife.
These two institutions agreed to terms of responsibility with the overall goal of recuperating the Bogotá River and improving flood control.
