Good morning,
Plastics were the result of the war time shortage of metals. The first pressurised water pipes were used in the Netherlands in the 50s. Guttering and downpipes followed in the 60s and soon after, soil pipes came in.
In Victorian times virtually every house had cast iron guttering and down pipes. Many older larger houses and mansions retained their lead systems. Still to be seen today on many a NT property etc.

PS, scribble may have been referring to the rightmove photo when she/he mentioned bins. I think there is one to the right hand side.
