Mapping the Underworld (MTU)
Many of the UK's existing buried assets were laid in Victorian times when the need to record accurate details of location and depth was not a priority. Even if such records were made, the reference points for measurements will probably have been lost - kerb lines have probably moved and buildings might well have been knocked down and replaced. Since then, many more pipes and cables have been laid and now records occur in many different formats including paper, microfiche, and digital, but very few of these are compatible as there has never been a single common standard for this data.

ThermoLiner plus - the highly flexible liner for negotiating sharp bends and dimension variations in house connections
The use of flexible tube liners in the rehabilitation of house connection pipes has taken hold as a technically mature alternative to costly "dig-out" repairs. Frequently, those house connection pipes that are in need of repair have not been installed in a professional manner. They commonly have sharp bends that are impassable for many of the liner systems prevalent in the industry. Frequently, a substitute is used that fails to produce satisfactory results.

Master plan for a sustainable supply and disposal infrastructure of mega cities - Part I
This is the first contribution of a three-part series that deals with the following approach: "Master plan for a sustainable supply and disposal infrastructure of mega cities". It is motivated by the fact that, due to the immense growth of the congested urban areas, the quality and sustainability of the underground supply and disposal infrastructure is gaining more and more importance, which, however, hardly effects the way of their planning. The single installation of sewers and pipelines with all its disadvantages is still predominantly applied. The aim of the technical paper series at hand is to present alternatives which do not only meet the requirements of sustainable construction but which may also be of high economic benefit.

Methodology for leak detection
New pipelines and in particular existing mains and service lines can start to leak due to bad joints, deterioration, stress in the soil and corrosion. This could lead to more extensive damage and loss of precious water, and therefore revenue. Finding a leak and pin-pointing the location will have an impact on the extent of rectification works, environmental burden and investment.
