Site 5 Proposition_Lift and Separate
Warakas acts as an island within the city of Jakarta. It is bordered by the Tanjung Priok Port to the west and north with rail and highway corridors encasing it’s southern and eastern borders. The northern and eastern boundary line will continue to be physically reinforced by the imminent construction of a highway network which will circumvent Warakas, physically cutting off the neighborhood from its surroundings.
Warakas’ island nature continues to be emphasized by the sole water system running through the site, the Kota River, with a dead-end, connecting river, the Buntu River. It runs south from the port to a reservoir southwest of the site which also take water from nearby systems. Warakas is low lying having been built on a swamp, but when inundation does occur it mostly happens from precipitation during the rainy season and only lasts for a few days. The higher elevated port located between Jakarta bay and Warakas acts as a buffer preventing tidal flooding.
Our design proposal for Warakas seeks to react to the rainwater and its inundating effects in the area, although temporary. Finding clean usable water for drinking or household uses in Jakarta is a constant struggle and this is especially true in Warakas, where most residents are priced out of bottled water leaving the only viable safe option to be buying the water from Bogor that is brought in twice a week and filtered on site. This clean water is scarce though and frequently runs out. Our design proposal seeks to react to the scarcity of water by adding a new water economy on-site. Using the dense urban fabric of the neigbourhood as an advantage, the design stiches together the roof scapes of different houses within the same block. the stitching process includes an elevated walk way containing pipes to move the water in the rainy season into retention tanks located in each block.
The retention tanks are located in structures of the same building typology that is currently existing. The intent is to not introduce a foreign aesthetic within the site that is readibly apparent, for the island nature of the site is typified by systems of defense within individual neighborhoods and close-knit ties to community peoples. The collected water will then be cleaned and sold to the community similar to other bottling and water cleaning operations that are on-site.
The drainage network on the roofs will also serve as a walkway network connecting segregated neighborhoods to each other. Walkways are the primary public space in Jakarta, thus the elevated network seeks to capitalize on this drainage network to produce more communal connections and moments of interaction. It will further the cleaning operations on the rivers as well. Bridging over the rivers will allow space for workers with rubbish baskets to lift trash flowing in the river. As a part of this occupation, trash is often reused especially plastic bottles and jugs. The bottles and jugs are cleaned and then used for refilling. The trash economy will only further assist the operation of selling rainwater as it will provide containers.
The intent of this system is to provide another water source economy into the area while alleviating sidewalk congestion, link spaces, and continue to enhance water quality operations that are already existing on-site.
