Guideline 064: Design of an Automated Flushing Siphon System

Articles, UC QuakeStudies

A guideline to inform designers on the design of an Automated Flushing Siphon System as a means to reduce the frequency of blockages on the wastewater network caused by pipe dips and flat grades.

Motivation This poster aims to present fragility functions for pipelines buried in liquefaction-prone soils. Existing fragility models used to quantify losses can be based on old data or use complex metrics. Addressing these issues, the proposed functions are based on the Christchurch network and soil and utilizes the Canterbury earthquake sequence (CES) data, partially represented in Figure 1. Figure 1 (a) presents the pipe failure dataset, which describes the date, location and pipe on which failures occurred. Figure 1 (b) shows the simulated ground motion intensity median of the 22nd February 2011 earthquake. To develop the model, the network and soil characteristics have also been utilized.
