The work of Norwich City Council, City Engineering Department.
1) Experimental Sewage Disposal Plant at Whitlingham. A small, specially constructed, experimental sewage treatment works at Whitlingham is shown. The process is explained in detail and the various features demonstrated by an operator. The contrast in the quality of sewerage is shown at the end. An operator holds up tWO test tubes, each containing a sample of water. City Engineers' Work.
2) Skid Tests, Newmarket Road. There are sots taken from a moving car as it proceeds through Eaton to Norwich. The Red Lion Public House is on the right hand side of the picture. The motor car continues towards Norwich. Later shots show the road as one is leaving Norwich. After these shots, the road is watered and skid tests are carried out using an adapted motor cycle and side car, carrying measuring equipment. There are also tests to measure the surface for breaking carried out by a van.
3) Tar Spraying. A road is sprayed with tar and chippings are applied. The surface is flattened by a steam roller.
4) South Park Avenue Housing Site. A caterpillar scraper and other heavy earth moving equipment prepare roads and sewers for a new housing estate in South Earlham. A heavy crane is seen working with a scoop.
5) Re-piling Of The River Wensum. The old concrete pillars are removed and the new ones placed in situ by the use of a heavy weight. There are many pieces of heavy plant in the picture.
6) Colman Road Resurfacing. Gravel asphalt is tipped into the Barber-Greene resurfacing machine. Parts of the machine are demonstrated during the sequence. The sequence concludes with the steamroller rolling the surface.
7) Yare Valley Sewer. There are views of the construction of an underground tunnel and of the ceiling runners being fixed into place. Most of the sequence concentrates on the engineering problems of constructing the sewer so close to the River. Above ground shots show the sewer passing between the river and the Cock public house at Lakenham. There are shots of the steel piles being driven into the ground and of the drag line excavator at work. Concrete is mixed, poured into place and then levelled by hand. The concrete pipes are placed in situ and the joint devised. At one stage there is a close up shot of foot pedals being used to control the crane.
8) Newmarket Road Works. This section shows the concrete being prepared and taken by lorry to the site where it is spread by hand and levelled by machine.
