In spring 2011 this area of comfortable-looking contemporary houses surrounded by tidy landscapi...

This paper gives an example of how predictive models of the deterioration of reinforced concrete pipes and the consequences of failure can be used to develop risk-based replacement strategies for redundant reinforced concrete pipe networks. It also shows how an accurate deterioration prediction can lead to a reduction of agency costs, and illustrates the limitation of the incremental interventi...

Raising of problem. A significant part wastewater in Ukrainian cities is discharged using sewer collectors with a diameter 300 to 1 400 mm, the depth which within 3…8 m. them destroyed due corrosion processes that take place surface space. Today, problem repair and restoration sewerage networks becoming especially relevant connection increased requirements for environmental protection. Failure ...

When inspecting sewers, it is required that discovered objects like damages or previously unknown laterals are entered into the existing sewer map at the correct metric position. On the other hand, odometry conditions in sewers can be very poor, and they may vary greatly with slip, slope, and sewage current. The paper describes a simple reasoning method for correcting the odometry error accordi...

Sustainable Urban Drainage Systems (SuDS) constitute an alternative to conventional drainage when managing stormwater in cities, reducing the impact of urbanization by decreasing the amount of runoff generated by a rainfall event. This paper shows the potential benefits of installing different types of SuDS in preventing flooding in comparison with the common urban drainage strategies consistin...
