Tees Cottage Pumping Station is a Victorian pumping station complex at Broken Scar on the A67 near Low Coniscliffe just west of Darlington. The site dates from 1849, and was built to provide drinking water for Darlington and the surrounding area. It is a scheduled monument housing two completely original pumping engines in fully working order: a 1904 beam engine, built by Teasdale Brothers of Darlington, which is still steamed using its original 1902 Lancashire boilers; and a rare 1914 two-cylinder gas internal-combustion engine, the largest such engine surviving in Europe. Both engines can be seen in operation on certain weekends through the year, using their original pumps to pump water from the River Tees.
