Halloween, it’s the spookiest time of the year, when our streets swarm with gruesome zombies, fearsome vampires and ghoulish ghosts. A time when myth and legend collide, and this year, staff at Anglian Water have had their own spooky encounter as a rare species of bat is has been discovered on one of its sites in Lincolnshire.

The Blow Wells in Tetney, North Lincolnshire have been found to house both the male and female species of the rare Nathusius Pipistrelle bat – a spook-tacular surprise for any visitors to the site this month.

The Blow Wells themselves are a natural phenomenon. They are a series of pools in which water rises from underground through weak spots in the earth’s clay to bubble to the surface, and form a special and valuable habitat.

However, according to local folklore the Blow Wells are said to have had a much darker past.

Legend has it that the dark depths of the Blow Wells contain a direct passage the underworld, and if anyone dare to swim in their torrid depths, they will immediately be dragged under to meet a gruesome end.

It is thought that the legend began to stop children from swimming in the water. They were told that the sensation from the constant water flow at the bottom of the 40ft blow well, similar to the bubbling of a natural spring, was actually a gateway to the afterlife trying to pull them under.

In keeping with its spooky tale, the rare and striking Nathusius Pipistrelle bat has been officially confirmed via DNA analysis, to be present at the site. It is the rarest of all the Pipistrelle bat species and has only been breeding in the UK since 1990.

The company now hopes to be part of the National Nathusius’ Pipistrelle Project which was launched in 2014 with to improve the understanding of the ecology, current status and conservation threats for Nathusius’ Pipistrelles in Great Britain.

As well as the close monitoring of these bats, Anglian continues to work on enhancing the biodiversity at the site. As a Site of Special Scientific Interest (SSSI), it has been under special protection by Natural England, working with Anglian Water in partnership with Lincolnshire Wildlife Trust.  It has been found to house six different species of bat, along with water voles, European otters, and a rare aquatic plant known as a water violet.

Having originated as a watercress farm that was used to supply watercress, including to The Ritz in London, these important blow wells were purchased by Anglian Water in 1962 to supply drinking water to North Lincolnshire.
