Here some links to a wastewater pyramid planed and built in the early 90s in Kolding, Denmark. Waste water is collected from the whole district (11000 m3 of sewage per year) and cleaned through a system of light, algae, and reed beds, before being released to feed a stream

Essay
Tirana Development
Tirana is a City which, after the fall of Enver Hoxha's regime in the early 90s, has experienced huge flows of immigrants from the poorer parts of the country into the city. As a result Tiranas population has tripled in only 18 Years. The administrative zone of Tirana, however, is bound to the boundaries of the early 90s, and all newer developments (summarizing more than half of the total land area) are outside this administrative zone, making plannings for the complete city politically challenging.
If one analyses the population density of Tirana, it can be seen that further densification of the town center is not viable, and therefore, the city needs space to grow, and a series of satalite centers need to be developed. If we then analyse the topography of the Tirana region we can see that the area to which Tirana can expand is very limited as it lies in a river basin, and the authorities to not want to build on the hillsides, as this would mar the face of the city, and might introduce climatic problems.
Thus the only way for Tirana to expand would be along the river axis, leading from Tirana to the sea. To prevent a blanket coverage of the whole river area we propose a system of stripes to array the various uses along the river, and order the development along this axis.
District Identities
A series of centers along the River presently already exist, however the uncontroled development in Paskuqan, Bathore, and Kamza has created many problems for these areas. One is the massive lack of infrastructure, and social institutions. Kamza, with a population of 100,000 has only a hand full of schools, a recent health center, no sports facilities, no public spaces, and no community facilities. It is completely dependent on the Tirana city center for most services.
The whole area is several kilometres long, swamped with detached houses, not showing any significant structural changes whilst travelling through the area. Thus a certain disorientation results, as one part of the city cannot be distinguished from the next.
Stripe Concept
Thus we propose a system of layering the river with perpendicular stripes of varying uses. By dissecting the recent developments along the river from paskuqan to the airport into a system of stripes, a zoning of the various districts is achieved and certain points of orientation created.
By analysing the typical characteristics of certain zones (however small these may be) such as street patterns, density, frequency of public phone boxes, and other public amenities, size of private gardens etc. and amplifying these features in their respective areas, a new sense of orientation can be achieved as each district becomes its own unique Identity.
River transport
To emphasise the importance of the river as an axis for fu´ture development connecting the various districts, and to take up the theme of rivers being the traditional modes of transport connecting various towns, a system of public transport is to be arrayed along the river, connecting tirana with the various districts and the airport. With small interventions, and by planing places along the riverside, we hope to achieve catalizers which will initiate further develop in the respective districts.
Green Corridors
Areas of low density and large open places are to be developed as a system of regular green corridors segmenting the city, thus creating borders between the various districts and creating points of orientation.
These stripes can be developed as CPUL's (continious productive urban landscapes). A series of layers are imposed over the open areas representing different usages; such as recreational, agricultural (community and privat gardens), playgrounds, sport fields, and public parks. There will be a strand, a green footpath, connecting the different usages and features, allowing for the various widths, shapes and forms that the green stripes presently have. The connecting element between the various green corridors will be the river, and the axis of public transport alongside it. Old industrial complexes can be reused for recreational or sports purposes.
Ecological aspects include providing clean air corridors letting the cold night air flow down from the hillsides into the city centres, minimizing the amount of sealed ground, thus preventing the occurance of floods along the river, and providing various spaces/habitats throughout the city.
Conclusion.
Hereby steps can be taken to ensure that further development along the river will be orientated, and integrate ecological and energetic aspects at an early stage. We see this as a method of relieving the pressures of city growth on the Tirana center, and reorganising the present unplanned developments along the River.
We also see a large potential in the river and the river valley to be developed into a funktional new series of towns, which will alleviate pressure, whilst improving living conditions for immigrants.
