Outside is a round monument which was installed when it opened. The plaque on the front reads ‘Yorkshire Derwent Scheme - This plaque commemorates the inauguration of stage I of the Yorkshire Derwent Scheme by Sir William Goode G.C.M.G. Chairman of the Water Resources Board, 10th September 1965’. Panning shots of the completed works and exterior site. Water is shown in the treatment mechanisms of the reaction tanks. Inside, a large control panel is shown. The river outside is shown. A diagram appears showing the different components of the treatment works, including ‘river intake, low-lift pumps, reaction tanks, flash mixer contact tank and filters, clear water tank, high-lift pumps, central control room’. The River Derwent is shown at the tidal sluice gates. Landscape shots of the river, tidal sluice gates and a bridge are shown. A man walks down some steps and looks over into the water. The screens which the initial water goes through before treatment are shown. The treatment works diagram appears and shows how the water goes through the low-lift pumps. The low-lift pumps in the treatment works are shown. The treatment works diagram appears and shows how the water goes then through to the reaction tanks. A man is seen walking around the exterior of the treatment works and up some steps to the reaction tanks. The reaction tanks in action are shown. The man walks over to the flash mixer. The treatment works diagram appears and shows how the water then goes to the flash mixer contact tank and filters. Flowing water is shown being mixed with chemicals in the flash mixer. It is then shown flowing onto the contact tank, and further on to the filters. A gauge that reads ‘Loss of Head, Feet of Water’ is shown. Water bubbling with compressed air is shown, which is then seen flowing away to recovery tanks. Recovery tanks are shown. Water pumping out of a pipe is shown.
