**1)** The majority of water used in the city is stored in reservoirs (large stocks of water) out side the city in the hinterland, from here it flows into the city were it is used, for drinking, cleaning, gardens and various other uses. Another source of water is rainfall, all most all new homes in the city have water tanks (smaller water stocks) which collect storm water from the roofs. These tanks are plumbed to the toilets washing machines and garden outlets. This way less water from the reservoirs are used, this helps to slow water levels from dropping in times of minimal rain. After being used the water flows out thru the sewerage system where it is treated and piped out to sea. Excess stormwater run off from streets, land, and from tank over flows flows into a separate system which makes its way into rivers, the harbour, or sea. ![Newcastle's Water Reservoirs, shown as blue circles][1] Newcastle's Water Reservoirs, shown as blue circles. ![Sewerage Plant][2] Newcastle's main sewerage treatment plant, from here it is piped 1.4klms out to sea **2)** Coal is one of the regions main exports, the coal is shipped to various places around the world from the port in Newcastle. Most coal arrives by train (flows in) , where is is stock piled before being loaded on a ship and sent off to it's final destination (flows out). This is also one of the major economic earnings for the city. ![Coal Trains][3] Coal Trains ![Coal loader and stock piles][4] Coal loader and stock piles ![Coal ship getting loaded][5] Coal ship getting loaded **3)** Public space is another from of stock for a city. Whilst some public spaces are official designated spaces that are designed as such, others are just left over spaces that evolve into a used space for the public. As with buildings over time, public spaces are removed and others added. Usually they are replaced by buildings, sometimes when the city sells them off to private developers (or with the non official spaces when the actually owner figures out what to do with the space). With the removing and adding of the space this is the flow. ![Newcastle Mall][6] Newcastle Mall, has declined in popularity since large indoor shopping centres have taken the market. Now looking at redevelopment. Changes in the future. The best change we could hope for water is more efficient use and less wastage, also with new technologies better treatment of the sewerage. With the movement towards sustainable energy, the market for coal will decline over time, and therefore the jobs and economy that goes with it. To counter act this more investment into the industries of the future (hopefully the sustainable ones) is needed, so as one industry winds down another takes it's place. A positive will be cleaner air with out the coal dust. With the change of public spaces over time the goal would be to create better, more enjoyable and successful space, with in the form of new ones and revamping the older less successful ones.
