Above is the plan of Xi'an which highlights the river and the different zones of the city.
As mentioned in the previous post, the solutions will be divided into three phases.
The first phase master plan will focus on residential zones.
Preliminary mapping and zoning analysis showed that there are 6 zones within Xi’an of which 2 were residential. The regions in blue are the zones which still have traditional courtyards within the houses. This solution will be transformed into gardens on the periphery of houses in the other residential zones. Each garden is designed with structural soil to work in a way that part of the rain water gets stored in cisterns to be used by the residences and the rest of the water is used to recharge the aquifers.
The traditional courtyards have an area of 4.5'x9'.0'. With this small area, the courtyards may not recharge much or any of the aquifers, but as a collective solution, they will not only help reduce surface run-off but also provide better quality water to the residents of the city.
The map shows the infrastructure of Xi’an. As you can see, the city has a lot of roadways highways and expressways. In addition to this it also has new hubs for public transportation being constructed within in the city. It is within these public transportation hubs that we are proposing new toilet systems that will help collect and filter the water further.
Two toilet systems will be proposed. The first system will be a set of split system toilets. These toilets will first provide an educational experience to the users as well as provide organic means of fertilizing the soils thereby reducing the pollution.
