Problem statement: Historically, water had been extracted from some of Cuba’s major aquifers at a higher rate than they were recharged, but in recent years the pace of water extraction appears to have intensifi ed. Surface waters diverted into man-made reservoirs can interfere with the natural recharge of aquifers. High evaporation rates from tropical region reservoirs can have adverse environmental impacts by increasing the concentration of minerals in irrigation water. Surface waters have been contaminated by industrial wastes and by the chemical runoff associated with the use of increasing amounts of chemical pesticides and herbicides.

Scant water distribution management, alarming condition of infrastructure together with high contamination of water resources constitute a scenario, where the need of establishing elementary infrastructure for water treatment opens possibilities to reformulate the image of infrastructure as a by-product of settlement and to relate it to its public role and use, as well as to the whole ecological process. The area of Puentes Grandes district in character calls for fully specifi ed design; suffi ciently open to integrate recreational dynamics of natural ecosystems.

Goal: The intention is to design beyond the polarized situation where architecture and landscape can be included as systems in an urban design. In the city scale the design solution should aggregate the development of neighbourhood of river Almendares banks and enforce its natural ecosystems. In the more local scale, design intention is to develop a formula capable of fusing previously separated morphologies of industrial production, hydrological infrastructure and public, green, recreation area.

Method description: Finding self-referential accommodation in a landscape that has lost its coherence; examining the site in order to discover possible rules for intervention; rediscover the landscape with its critical properties. Use landscape as both structuring element and medium for rethinking urban conditions, to produce everyday urban spaces and architectural solutions.

Relevance: Take the fl oor in discussion concerning the issue of how dense urban forms emerge from landscape and how urban ecologies support performance spaces. Search for new basis for emergence of form geared to the technological and ecological realities of the contemporary city.

The project in its large scope deals with the conditions of butting edges of Metropolitan Parque de la Habana covering the valley of and two districts on its Eastern and Western

border. The analysis unfolds that both topographical conditions and infrastructural elements limit the access to the green areas. On the urban level the project intends to create pedestrian connection between and districts; at the same time it facilitates access of citizens into park area. The old railway embankment will be given a role of a spine of the project. Along the pedestrian green line various interventions will be situated. New circumstances will constitute a programmatic infi ll in variable patchwork of present land development. Recreational programme of the park will be replenished. On one hand, proposed

elements will support and propel establishment of amusement infrastructure and on the other hand contribute to improvement of environmental conditions of discussed area.

An attempt was made to examine the park as an object in the city. The water contamination threat problem revealed in the research on agricultural regions leads to the analysis of the drinking water resourses.

The objectives of the park’s existence are to reverse deforestation; create opportunities for urban agriculture; clean up the territory, the river and industrial polluters; explore alternative technologies for sewage treatment; introduce integrated solid waste management practices; restore and create housing; improve recreational facilities and services; improve accessibility to the park; promote

The Metropolitan Park of Havana covers to the big extend economic self-suffi ciency and introduce participatory and environmental education processes. the end of watershed of Almedares river - main drinking water source. This fact became a main reason to deal with the analisis of the park area.

The site occupied by the PMH project is approximately 700 ha. It is one of four major parks along the river’s basin, conceived by the 1963 Master Plan. As such, it is an intrinsic part of the capital city’s greenbelt system. There is a signifi cant diversity of operations within this area both in the use of soil and buildings and in green spaces and social components. This is demonstrated by the diff erences between the mansions inhabited by the middle and upper classes in the Miramar and Nuevo areas and the modest houses of the working-class neighbourhoods of Pogolotti nurceries private farms dwelling areas topography conditions inner partitions pollution interconnections and El Cerro.

Leakage In Havana in order to channel the required amount of water for each person, it is necessary to provide more than 600 litres/person/day. It is believed that more than 55% of such volume is lost because of leaks in the water supply

In Havana, it is suspected that the intensive agricultural activity in the recharge area of Havana South is polluting the karstic aquifer that is the main source of water for the city of Havana and surrounding areas. Carbonate aquifers are very sensitive to anthropogenic interference and careful management is necessary for their continued use.
