Site 2 Proposition_Water Economies: Re-Distribution through Rainwater Harvesting
Large mega-complexes, which are commercial and economic hubs for the city, and residential communities, which are directly adjacent, receive water in two distinct ways in Glodok; tap water, and water delivered in jugs via trolley. However, both sources ultimately stem from PAM JAYA. As this monopoly precludes any notion of redundancy, and therefore security in water delivery for the large scale complexes and small scale communities in Glodok, we believe this risk is where the designer can add value by recognizing and harnessing another water source. Utilizing the rainwater run-off from the large complexes, filtering out acidity, and collecting it for use in the event of PAM JAYA’s deficiency, presents the dual immediate benefits of reduced pumping loads out of the drainage canals, and of financial returns by selling this excess water. This source of water frees the trolley operators from their current tether to a single water source, and by putting the power in the hands of the distributors, the social network of often geographically sparse delivery points is much more effectively accommodated. Rainwater nodes and the existing water tank nodes amplify the power of the distribution network, adding redundancy, greater efficiency, and providing a platform for interaction between the very distinct scales and interests of the commercial and residential.
