This paper describes the application of uPVC pipe on a large irrigation contract. The project is known as the Sadova Corabia Irrigation System and is located in south-west Romania. It is the largest technically advanced irrigation scheme to be undertaken anywhere in the world. Taylor Woodrow International Limited are...

My task in this paper is to convey my experience in the use of uPVC in soil drainage schemes at Port Talbot. I began incorporating plastics drains in building projects in 1966, and owing to experience gained I have continued to specify its use in schemes under my control since that date. One might ask me why I began...

This paper briefly describes the development of a sealed access uPVC drainage system and techniques that have been introduced to improve the testing and cleansing of buried pipework. An example of the system in use is then given. The case &udy deals with the application of the Rodding Point drainage system, assessed...

During the years 1966 and 1967, early ones in the preparation of the Verwood Sewerage Scheme, it would be fair to say that visits to the offices of the Wimborne & Cranborne Rural District Council from representatives of the PVC pipe industry were few The representatives that called quite regularly to enquire of...

In the Nordic countries common research work concerning buried sewer plastics pipes has been followed by an independent evaluation group led by the authors. This group was founded in 1968 by the Nordic plastic industries in order to create a forum for independent evaluation of all the various research programmes so...

The first pipes made from PVC were pressure pipes and came into ye, on a small scale, shortly before the second world war. It was not until the early 1950s that the big growth in this application really began, and it took a further ten years or so for the excellent experience gained in pressure-pipe applications to...

Plastics pipes have been used for a variety of applications since the mid-1950s, but they have not been considered very seriously by the Gas Industry until fairly recently. Until 1965, the majority of fuel gas in the UK was 'towns gas' with a high content of liquid aromatic hydrocarbons. This 'wet' gas attacked pipes...

Paper 9 presented at the Symposium in 1970' was an attempt to provide simplified design data for uPVC sewer pipes as had been previously done for rigid (esentially brittle) pipes by the Building Research Station2> 3. The calculations were made in Imperial units and the charts prepared in respect< of inch series...

When a pipe network is designed it is usual to estimate firstly what flows are required at its various outlets, what pipe sizes are needed in the net, and then what type and number of pumps are necessary to deliver the flow under the static and frictional heads imposed by the ground topology and the overall system...

The business of ASL is in providing aeration equipment for the biological oxidation of domestic sewage and suitable trade wastes. Very briefly we provide equipment to aerate tanks from, say, a 2 m cube up to those at major sewage works, the largest of which is 41.0 m wide and 223.0 m long, operating at a water depth...

Chairman: Speakers have often mentioned the purpose and use of the products, and if I was speaking only from the building side I would say that perhaps in this day and age one needs to think of more than just current use. The environment, and the building environment particularly, is a complex thing. There are...

I propose to deal with this very wide subject in two stages: firstly, to discuss the ways in which it is possible to gain an education in plastics, and then to spend a short time considering whether or not this provides the right type of person for the plastics industry in general, and for those who make and use...

There is nothing new about sanitation — it was discovered at ‘Skara Brae’ in the Orkneys that Neolithic stone huts were provided with crude drains leading from the recesses in the walls that are supposed to be latrines. One of the earliest known baths came from Crete and is dated about 1700 BC, some 3600 years old,...

Plastics materials are now being extensively used to provide pipelines for effluent conveyance, both by industry and by numerous Public Authorities. Intensive efforts to control pollution have led to stringent examination of conventional drainage methods and materials, and has highlighted the need for continuous...

Flexibility in drainage systems has been recognised by most engineers as essential where ground movement may occur; for this reason flexible joints were introduced and are now cheaper than fully rigid lines Fully flexible pipes was the next development and they are now much more common. For a long time plastics pipes...

I should perhaps begin by explaining that the medical and surgical plastics in the context of this paper have nothing to do with plastic surgery. Plastics pipes and fittings have found ready acceptance in the field of medicine and surgery. The wide choice of plastics available enable many of the traditional...

The discovery of the Groningen gas field - now the largest in the world - has wrought great changes in the pattern of the energy supply1 in the Netherlands (Fig. 1). Not only has the share of coal declined, but the increase in energy demand has to a large part been covered by natural gas, thanks partly to the...

This Paper outlines the practical background within gas dis- tribution against which the introduction and use of plastics pipes may be considered. It concentrates on the practical and economic aspects of plastics pipes applied to distribu- tion activities, and in particular the most common and widely...

Since the last International Symposium, held two years ago, there have been a number of important developments in the use of plastics pipework and associated fittings in plumbing and drainage. Most notable are the acceptance and approval by the BSI, with the issue of BS 4660: 1971,4576: 1970, 4344: 1969 and 70, and...

The West Wilts Water Board was set up in 1960, and among the many problems facing the Board were the following: Large areas of subsoil composed of aggressive Kimmeridge and Oxford clays whch were causing repeated corrosion failures of spun iron mains laid only 100 years before, aggravated by seasonal ground movements...

In addition to the processes of substitution in the fields of drinking water supply and drain and waste pipes for domestic and industrial application, other fields of application have been considered during the past years. Application of plastics pipes seems advantageous in those fields where the specific...

Those materials such as plastics pipes and plastics articles which have a relatively low labour content must inevitably become more economical relative to their conventional rivals as inflation continues, and certainly this is a process which has been shown to be true over the past two years. The trend must continue,...

It is a well known fact that plastics have advanced into fields of application that have hitherto been open only to conventional materials. This is a development that is making steady progress, from which the question arises as to what places, and under what conditions, plastics pipes can be suitably used for...

The last year has seen one of the most depressing periods since the war in the history of the plastics industry. This has applied to both the manufacturers of the polymeric materials and also to the fabricator. Not only has the general level of business activity been very much lower than forecast, but new capital...

We are all brought up to believe that 'Necessity is the mother of invention' but, as Brian Locke has recently pointed out 'In a developed society invention is the father of necessity. If it were simply the other way round then r & d would not involve real planning. A need would merely arise as in primitive societies,...
