Basin plans have become a core element of water management in the 21st century. Systematic analytical scrutiny of the contents of basin plans is nonetheless scant. This paper develops a framework for assessing basin plans and systematically applies it to understand how contents of basin plans vary. The paper synthesizes a definition of ‘basin plan’, generates a classification system for basin plans, and proceeds to classify a regionally diverse set of 23 basin plans. Major findings are that basin plans typically contain the components and sub-components suggested in best-practice guidelines. Focus on some issues that are presumably central to water management such as water quality and quantity is nonetheless comparatively low. Disaggregating basin plans suggests that developing-country transboundary plans are more geared towards hydropower development, navigation and coping with uncertainty, while developed-country and national plans appear to focus more on issues such as water quality and fish management. It is hoped that findings contained in this paper support future basin plan development by informing those crafting basin plans of the options available to them.
Assessing buried infrastructure deep under buried infrastructure
In preparing for its water future, the Region of Peel (Peel) adopts a unique assessment strategy for a newly constructed potable water transmission main that extends deep underground through the heart of Peel Region. The effort is paying off, with Peel decision makers gaining a better understanding of this pipeline as it comes into service.
An assessment of static and dynamic models to predict water treatment works performance
The relative accuracy of static and dynamic water treatment works (WTWs) models was examined. Case study data from an operational works were used to calibrate and verify these models. It was found that dynamic clarification, filtration and disinfection models were more accurate than static models at predicting the final water quality of an operational site but that the root mean square errors of the models were within 5% of each other for key performance criteria. A range of abstraction rates at which the WTWs...
Numbers Speak Volumes: Water Distribution Assessment Increases System Operability To 84 Percent
This large Midwest utility maintains and operates water collection, treatment, and distribution systems, as well as wastewater collection and treatment systems and stormwater management systems for its residential, business and wholesale customers in the region. To ensure the accessibility and quality of water services to meet the growing needs of the region, the Utility needed to conduct a complete assessment of their water distribution system. The limited internal resources and need for quick results were more...
How to Assess Fall Hazards
Fall hazards are an ongoing concern in most workplaces and include both falls from heights as well as falls from the same level. Slips, trip and falls from both categories consistently rank among the top causes of both disabling injuries and deaths in all types of workplaces, from construction sites, to manufacturing operations to warehouses to offices. In fact, the only other category of fatalities in the workplace that has higher numbers is motor vehicle accidents. As with all hazards, the first step in...
New indices for reliability assessment of water distribution networks
This paper presents new indices to evaluate the reliability of water distribution networks (WDNs) usable in the design, planning and management of these networks. Since the pressure-driven analysis (PDA) of WDNs produces more accurate results than the demand-driven analysis, the new indices are proposed based on the PDA. In the proposed measures, nodal pressures, nodal available discharges and the energy loss per unit length of pipes are considered as the main factors influencing the reliability of WDNs. The...
