Inspection (without excavation) of impluvia in Paestum, Pompeii and Rome indicated that the pavement surface in the impluvia was porous, or that the non-porous stone tiles were separated by gaps significant enough to allow a substantial quantity of water caught in the basin of the impluvium to filter through the cracks ...
The velodrome of the London Olympic Park is designed to harvest rainwater. In recent years, rainwater harvesting has become more common due to increasing water prices. While rainwater harvesting has been employed in high-profile facilities like the velodrome of the London Olympic Park, the UK's ongoing revival has lagged behind other countries such as Germany (the present world leader in ...
