Older installations, known as "high suite combinations", used a high-level cistern (tank), fitted above head height, activated by a pull chain connected to a flush lever on the cistern. When more modern close-coupled cistern and bowl combinations were first introduced, these were first referred to as "low suite combinations".
Often old toilets still have high-level cisterns in the service ducts. On the outside, the toilet is flushed by a handle (just like an ordinary low-level cistern toilet) although behind the wall this handle activates a chain. Sometimes a long flushing trough is used to allow closets to be flushed repeatedly without waiting for the cistern to ...
These cisterns are easily spotted at street level with manholes labeled CISTERN S.F.F.D surrounded by red brick circles or rectangles. The cisterns are completely separate from the rest of the city’s water supply, ensuring that in the event of an earthquake, additional backup is available regardless of the condition of the city's mainline ...
It is designed to allow a shorter interval between flushes than individual cisterns.

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 ...
A low-flush toilet (or low-flow toilet or high-efficiency toilet) is a flush toilet that uses significantly less water than traditional high-flow toilets. Before the early 1990s in the United States, standard flush toilets typically required at least 3.5 gallons (13.2 litres) per flush and they used float valves that often leaked, increasing their total water use.
Both schemes were superseded by a new system, proposed by William Yarnold in 1697. He negotiated with the Common Council of Newcastle to allow him to lay pipes and build storage cisterns, but also took the precaution of obtaining an act of Parliament to authorise the works, with the Newcastle upon Tyne Water Supply Act 1697 (9 Will. 3. c.
