A detective from Humberside police says that currently they don't know how long the baby's remains were left in garden drain at a property on Scartho Road, Grimsby.
Det Insp Christine Calvert said both the plumber who found the body and the occupants of the house were in "extreme shock" following the discovery.
It's hoped the post-mortem on Monday will reveal more about the death, which is currently being treated as unexplained.
