- Henri Lefebvre, The Right to the City — In brief, the right to the city is the right to the production of a city. The labor of a worker is the source of most of the value of a commodity that is expropriated by the owner. The worker, therefore, has a right to benefit from that value denied to them. In the same way, the urban citizen produces and reproduces the city through their own daily actions. However, the the city is expropriated from the urbanite by the rich and the state. The right to the city is therefore the right to appropriate the city by and for those who make and remake it.

@SteveKLord ' Tests, carried out as part of its work, have shown that water can be absorbed at a rate of 10,000 litres per square metre, per hour. '
1 square meter of surface area at 1 cm is 10 litres, so a square metre would have to pass 10 metres (1000 cm) deep of water per hour, or a velocity of 2.78 centimetres per second, unless I did the math wrong.
That seems like a very high number for a ceramic to filter, even considering the gaps.
The ceramic tiles might have that rate of water flow, but the ground beneath it probably doesn't.
