The Selection of Priority Pipe Sections for Sewer Network Renovation

Orlov, Vladimir / Andrianov, Alexey

Operative and planned rehabilitation of old pipe networks, including water disposal systems, is a relevant objective of modern city. It is especially difficult to make pipeline reconstruction works in large cities with high construction area density, transport moving intensity, also full of multifunctional both underground and above-ground infrastructure. All these factors set a lot of restrictions for open excavation methods of pipelines repair and reconstruction. That is the reason why trenchless technologies are becoming more popular among the engineers. A wide range of trenchless techniques provides people with convenient method of fast and effective reconstruction processes in comparison with durable and inconvenient open excavation. This fact leads to a necessity of creating a strategic planning of pipeline rehabilitation. This article presents how to operate the first step of such strategic planning – choosing the priority pipe section for sewer network renovation. The most convenient way for choosing one specific section from a great range is to use a program package based on mathematical algorithm that takes into account a quantity of different factors. This paper presents such a program created by authors and describes its interface, date input and processing.
