Rehabilitation Priority Determination of Water Pipes Based on Hydraulic Importance
This paper describes a study conducted to develop a method to facilitate more reliable determination of the rehabilitation priority order for water pipes by taking into account the pipes’ hydraulic importance. Existing methods use only the pipeline deterioration rate to determine the rehabilitation priority order. Accordingly, the deterioration rate under normal conditions and the hydraulic imp...
متن کاملSmart Pipes—Instrumented Water Pipes, Can This Be Made a Reality?
Several millions of kilometres of pipes and cables are buried beneath our streets in the UK. As they are not visible and easily accessible, the monitoring of their integrity as well as the quality of their contents is a challenge. Any information of these properties aids the utility owners in their planning and management of their maintenance regime. Traditionally, expensive and very localised ...
متن کاملPrioritising Water Pipes for Condition Assessment with Data Analytics
This work proposes a method for prioritising critical water mains (CWMs) with high risk, in terms of both failure probability and consequence costs. The proposed method can improve the prioritisation of high-risk CWMs requiring condition assessment in the near future and will further optimise the operational maintenance of water utilities. Due to the improved prioritisation, water utilities can...
متن کاملA Joint Model for Water Scarcity Evaluation
To make a real difference for our thirsty planet, we establish the water demand-supply model and the Advanced Water Poverty Index (AWPI). First, we develop a dynamic demand-supply model to measure the ability of a region to satisfy its water consumption. On the demand side, we fit agricultural and industrial water needs by the Grey Verhulst prediction model, then we consider domestic needs thro...
متن کاملDistal interphalangeal joint arthrodesis with Herbert screw
Fifteen patients underwent arthrodesis of finger distal interphalangeal joint (DIP) and/or thumb interphalangeal joint (IP). Only Herbert screw intramedullary compression fixation was used. There was one faulty proximal thread placement with some pain, but the patient refused further surgery. Full union was achieved in 14 of the cases, with prominent hardware in one and intolerance to cold in two.
