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.

Valves play key role in cleaning and maintaining aqueduct pipes

When the Jordan Valley Water Conservancy District in Utah decided to clean its water aqueducts, a new series of large-scale valves were needed to allow the cleaning device to pass through as well as reliably hold back the water during manual inspections. Assisting the water district in this task were 72” knife-gate valves from ITT Engineered Valves Group.

Trenchless Australasia

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.

Milestone in the Gotthard Base Tunnel - first breakthrough by a tunnel boring machine

The first tunnel boring machine (TBM) in the Gotthard Base Tunnel started out in the east tunnel from Bodio in November 2002. Two months later, the second TBM started driving in the west tunnel. A number of different geological zones had to be overcome along the approximately 15 km route to the multifunction station at Faido. The highly diverse geology impaired driving progress. Modifications to both TBMs brought sharp improvements. In December 2005, with 38 metres, the TBM in the east tunnel attained the highest daily advance rate of any TBM in the Gotthard Base Tunnel to date.

Evaluation of membrane pre-treatment to further wastewater reuse

CDM recently completed an in-depth, two-phase study to assess the potential for membrane technologies to expand the reuse of secondary effluent. Commissioned by the Water Environment Research Foundation, CDM, in collaboration with the University of North Carolina at Chapel Hill, conducted research that will guide utilities and regulatory agencies in expanding wastewater reuse. Since rapid urbanization and severe regional droughts make it clear that fresh water supplies cannot continue to indefinitely meet water demands, wastewater reuse will be needed to ensure water sustainability.
