A cistern (Middle English cisterne, from Latin cisterna, from cista, "box", from Greek κίστη kistê, "basket") is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few litres to thousands of cubic metres, effectively forming covered reservoirs.

Plug-in disinfection method

A method of disinfecting a fluid system having a reservoir containing a first fluid and a flow path in fluid communication with the reservoir, wherein the first fluid is selectively released from the reservoir to the flow path. A receptacle containing a second fluid, which comprises a disinfectant, is fluidly connected to the fluid system, the internal pressure of the receptacle is higher than the pressure in the flow path. The disinfectant may comprise a peroxide. The fluid system is configured such that the second fluid is retained in the receptacle when the first fluid is not released from the reservoir, and such that the second fluid is drawn into the fluid system from the receptacle when the first fluid is released from the reservoir. The receptacle is fluidly connected to the fluid system via a non-return valve 3. The system may be a plumbing system with the flow path defined by pipes 8 connecting the reservoir 9 to a shower 4, a sink 5, and a toilet with a cistern 6. Flushing the toilet releases water from the cistern into the flow path, generating a pressure differential which activates disinfectant flow from the receptacle 2 into the pipes.
