Water, sanitary and waste services represent a substantial proportion of the cost of construction, averaging 10% of the capital costs of building and with continuing costs in operation and maintenance. Nevertheless, they are often regarded as a 'Cinderella' within the building process. Parts of many different codes and regulations impact on these services, making an overall viewpoint more difficult to get. This new edition of this classic text draws together material from a variety of sources to provide the comprehensive coverage not available elsewhere. It is a resource for the sound design, operation and maintenance of these services and should be on the bookshelf of every building services engineer and architect. more...

What is loosely described as ‘acid rain’ is not a new phenomenon. The burning of coal and other fossil fuels must have always resulted in the production of sulphur dioxide, and, where the combustion temperatures are high, of oxides of nitrogen. These may be present in various stages of oxidation and are often referred to as simply SOx and NOx. The Clean Air Act 1956 with its limitations on the burning of raw coal in urban areas has virtually eliminated ‘smog’ in British cities but has not directly reduced the SOx emissions. It is only during the last decade or so that Acid Rain has become a topic of discussion vying with nuclear energy in its emotive power. Initially attention was mainly concerned with the alleged effect of these gases and the acids formed therefrom on lakes and rivers in Scandinavia. This concern was soon followed by reports of serious damage to, for instance, the Black Forest, and, more locally, to lakes in the Galloway area and damage in other parts of Scotland. In the case of these and many other examples, suggestions, still to be verified, have been made about the probable origin of the pollutants. more...
