We used to go down this place quite regularly as young'uns, and everyone called it Turtle Tunnel back then. Anyways, on Friday night, myself and GAMBINO armed ourselves once again with lights and cameras, and went down to have another look, and to take some pics.

Esholt Water Treatment works can be seen here....
