Development and performance of a parsimonious model to estimate temperature in sewer networks

This paper presents a model (inspired by another model) to calculate water temperature in free-surface flow with two main innovations: the convective heat transfer occurs only at the wetted perimeter of pipes, and the model was integrated to commercial software used for hydraulic calculations in drainage systems. Given these innovations, we...

Effects of Climate Change on Drinking Water Distribution Network Integrity: Predicting Pipe Failure Resulting from Differential Soil Settlement

Climate change may result in lowering of ground water levels and consolidation of the soil. The resulting (differential) settlements, associated with soil property transitions, may damage underground pipe infrastructure, such as drinking water distribution sys- tems. The work presented here offers an approach for the prediction of pipe failure...

Predicting The Impact Of Climate Change On Pipe Failure In Drinking Water Distribution Systems

Underground water infrastructure can be vulnerable towards climate change. In previous research, correlations between weather parameters and pipe failure rates in the drinking water distribution systems (DWDS) of the Netherlands were found. Using the statistical relations between pipe failure frequencies and weather conditions, a methodology is...

CFD in drinking water treatment

Hydrodynamic processes largely determine the efficacy of drinking water treatment systems, in particular disinfection systems. A lack of understanding of the hydrodynamics has resulted in suboptimal designs of these systems. The formation of unwanted disinfection-by-products and the energy consumption or use of chemicals is therefore higher than...
