Description: The large building on the right is the Corporation waterworks pumping station. Immediately in front of this is its reservoir. Trent Bridge can just be seen on the right. The new Trent Waterworks Company opened its works near to the present Town Arms at Trent Bridge in 1831 (The gothic roof of the Town Arms can be seen in the centre of the picture). This remarkable system, the first in the country to provide a supply at constant high pressure so preventing contamination from entering the mains, was constructed under supervision of its designer, the Company Engineer, Thomas Hawksley, then 25 years old. Water flowed through brick filter tunnels laid in the gravel beds on the north side of the river into a reservoir adjoining the pumping station. From there it was pumped by a 40 HP rotative beam engine to a new reservoir built on the corner of Park Row and the Ropewalk. Parts of this 15 inch cast-iron water main between the pumping station and the reservoir remain in service today, although the pumping station itself no longer exists (demolished c 1900).
