London sinks were originally shallower than Belfast sinks. [4] One plumbing guide in 1921 suggested that the Belfast sink was 38 centimetres (15 in) deep.) [ 6 ] Some believe this was because London had less access to fresh water (and thus a greater need to conserve water), but this theory is now contested.
George Jennings (10 November 1810 – 17 April 1882) was an English sanitary engineer and plumber who invented the first public flush toilets. Josiah George Jennings was born on 10 November 1810 in Eling, at the edge of the New Forest in Hampshire. He was the eldest of seven children of Jonas Joseph Jennings and Mary Dimmock.
At first, the heavier solids were channeled into ditches on the side of the farm and were covered over when full, but soon flat-bottomed tanks were employed as reservoirs for the sewage; the earliest patent was taken out by William Higgs in 1846 for "tanks or reservoirs in which the contents of sewers and drains from cities, towns and villages ...

In some homes, there were upwards of three kitchens. The kitchens were divided based on the types of food prepared in them. [4] The kitchen might be separate from the great hall due to the smoke from cooking fires and the chance the fires may get out of control. [5] Few medieval kitchens survive as they were "notoriously ephemeral structures". [6]
Calculations were performed on these objects, as opposed to a range of cells, so adding two-time series automatically aligns them in calendar time, or in a user-defined time frame. Data were independent of worksheets—variables, and therefore data, could not be destroyed by deleting a row, column, or entire worksheet.
The Metropolitan Commission of Sewers was formed at the same time, water filtration was adopted throughout the country, and new water intakes on the Thames were established above Teddington Lock. Automatic pressure filters, where the water is forced under pressure through the filtration system, were innovated in 1899 in England. [9]
