Construction of the interceptor system required 318 million bricks, 2.7 million cubic metres of excavated earth and 670,000 cubic metres of concrete. [93] Gravity allowed the sewage to flow eastwards, but in places such as Chelsea , Deptford and Abbey Mills , pumping stations were built to raise the water and provide sufficient flow.
Construction of the interceptor system required 318 million bricks, 2.7 × 10 6 cubic metres (9.5 × 10 7 cu ft) of excavated earth and 670,000 cubic metres (24,000,000 cu ft) of concrete. [5] The innovative use of Portland cement strengthened the tunnels, which were in good order 150 years later.
In total, five interceptor sewers were constructed north of the Thames. Three were built by Bazalgette, and two were added 30 years later: The northernmost (Northern High Level Sewer) begins on Hampstead Hill and is routed past Kentish Town and Stoke Newington and under Victoria Park to the start of the Northern Outfall Sewer at Wick Lane.

There are two main types of gravity sewers, sanitary and combined. Sanitary sewers only treat the ...
Schematic of a simplified sewer: Smaller diameter pipes are laid at a shallower depth and at a flatter gradient than for conventional sewers. [1]Simplified sewerage, also called small-bore sewerage, is a sewer system that collects all household wastewater (blackwater and greywater) in small-diameter pipes laid at fairly flat gradients.
