CAT SITE

Vilvoorde    <   Cat site    > Machelen  

Location, location, location …

Cat site is the name of a 55ha area owned by Renault, in the territory of Vilvoorde et Machelen, it is located near Brussels Airport, the E19 and next the Vilvoorde Station. Due to former industrial activity and use as a landfill for household waste, the surface is heavily contaminated, a large number of actors are concerned with this site, and many projects have been thought for the futur of this area.

CAT SITE & OPPORTUNITIES

Cat site represents a big opportunity of developement for for Vilvoorde and Machelen, that today are not well connected between them, A 55ha parking plot can become a place to be, creating relationships , activities,,and a new area for differents economies to be developed.

The Rain, the topography , and the lack of impermeable soil, causes flood on the site, the amount of water could be recollected in a more efficient way and reuse on site.
Almost 1/3 of the site was used for landfill activity, about 90 000 m2 of landfill but today it is underground, and it’s cover by the parking for Renault. The landfill on site has household waste, so the decomposition of the organic waste génerate gases, one of the reasons why every landfill is rich on methane gas. This landfill gas can be collected and become electricity and heat, for industrial uses, commercial uses and for housing.

LANDFILL GAS COLLECTION & STRATEGIES

Landfill gas (LFG) is generated through the degradation of municipal solid waste (MSW) by microorganisms,landfill gas collection is typically accomplished through the installation of wells installed vertically and/ or horizontally in the waste mass. The gas is extracted and piped to a main collection header, where it is sent to be treated or flared. If the landfill gas extraction rate is large enough, a gas turbine or internal combustion engine could be used to produce electricity to sell commercially or use on site.

For developping the project we needed to have some data about the amount of gas wells, and to know how many M3 of landfill becomes wastes, how many tonnes of waste becomes biogas, and the amount of biogas to have electricity, this research will allow to know if the project it’s possible.

Also a landfill cap will allow to create from the landfill a landscape, with some vegetation on top of it, but it’s necessary a soil barrier layer, a drainage layr, a granular o geotextil filter, a protection layer, and finally a top soil so we can have vegetation .

A NEW CAT SITE

The new site, has had differents master plans, not yet one definitif but there are fixed projects, and one of them is the hospital for Vilvoorde. The goal it’s to creat a new master plan for CAT site, respecting the project of the new hospital.

First by creating blocks, for the hospital, the hospital facilities, Bright park ( also a project for industries), adding offices, commercial areas, leisure , activities, we could normally find next a train station .Other important point it’s to provide more open spaces, creating a green corridor, and for last, open the underground river , for depolution, water treatment, and to recollect rain water .

The project for the site to be developped it’s a Natural Swimming pool and a Sport center , in the middle of a park in CAT SITE, it’s between mixing leisure and sportive activities, trying to take advantage of the opportunities of the site, the location , the flood, and the landfill.

CAT Swimmig Pool

How it works?

The distribution of flows and activities on site … the gas recollected from the landfill area, will go to a gas tratment facilitie in between the two landfill,  and the gas treated will go directly to a facility that will transform it into energy and heat near a existing electric tower  , and the heat that has been recovered could be used, in the new swimming pool.

Natural Swimming Pool

A natural swimming pool is a chemical-free pool that uses the same principles as nature to filter out harmful microorganisms. This is how the system works: The pool has two distinct parts: the swimming area and a regeneration zone that features all types of plants that feed hydroponically on the water.

The project

The project has in one side a natural swimming pool, with two pond, and 1/3 of the pond it’s the regeneration area for the swimming pool, and has direct contact with the users, and the landscape around, also for the cold days, it’s important to have an inside swimming pool, with an olympic swimming pool and a learning swimming pool.

In the ground floor the prject has a building for the inside swimming pool, and another that connects the natural swimming pool and the inside swimming pool, with changing rooms, precleanse spaces, toilets and the plant for the swimming pool , with the idea of allowing the inside swimming pool to be around natur in almost the 4 facades.

The first floor of the project have a sport hall , and most of the program from the building connecting the two swimming pools, respecting the dry and wet zones, and having a cafeteria as an important part of the program.The day and night int the CAT swimming pool
