Crisis Situations

<div> <p>Due to the fact that water systems belong to critical infrastructure, diverse methods of its management assessment during crisis situations are applied. In these methods both technical aspects and human factors, that have an impact on safety of water supply to the recipient, are considered. Also assessment tools for water supply were applied for failure assessment in the water supply system (WSS) management. The safety functioning of WSS is associated with analysis of relations between threats, reducing the frequency of their appearing, and, if threats appear, with the identification of their causes and reducing their negative consequences. Undesirable events are the result of phenomena independent from the human will, as well as those related to human activity, that in a significant way influence the WSS functioning. Crisis situations that are affected by such undesirable events having nonrandom (rare events do not have the statistical stability), but also not-determined character, demand specific and interdisciplinary research methods.&nbsp;</p> </div> <p>&nbsp;</p>

Crisis Situations

The approaching prospect of obligatory implementation and pursuit of Water Safety Plans forces water companies to reflect on supplies in crisis situations that, for example, relate to the closure of a basic intake, or scarcity of water due to climates changes (droughts). Where supplies are diversified, there can be greater certainty as to the continuity of good quality supply, even in an emergency. As one of each country’s systems of critical infrastructure, the collective water supply system (CWSS) should be protected, with the diversification of supply treated as a basic tool to raise levels of security among consumers. This article, therefore, presents a method from the authors’ by which diversification may be assessed, including by reference to basic and key elements of the CWSS capable of affecting the continuity of water supply. Sample calculations using the proposed method are also presented here for selected Polish cities. In the event, as only one Polish CWSS can be assigned to the category representing excellent diversification, the suggestion is clearly that Poland’s systems must still progress with the diversification of water supply, in order to further reduce the risk of water shortages.

Operational Data

Initiated by a case study to assess the effectiveness of the modernisation actions undertaken in a water supply system, some R&D activities were conducted to construct a global predictive model, based on the available operational failure and recovery data. The available operational data, regarding the water supply system, are the pipes’ diameter, failure modes, materials, functional conditions, seasonality, and the number of failures and time-to-recover intervals. The operational data are provided by the water company responsible of the supply system. A predictive global model is proposed based on the output of the operational data statistical assessment. It should assess the expected effectiveness of decisions taken in support of the modernisation and the extension plan.

Risk in Water Supply System Crisis Management Water supply system belongs to the so called critical infrastructure of cities, and it should be a priority task for waterworks and even for the local authorities to ensure the suitable level of its safety. This system is characterised by its continuous work and requires high reliability level for its operating as well as for its safety, it is unique and its particular elements have different functions and simultaneously they interact forming an integral whole. The main aim of this paper is to present problems associated with water supply system safety management in a crisis situation.

Centre of registry and cadaster provides with the developed DSS information support for management of the Moscow River water supply system since 2009. Information support includes hydrological and water resources analysis, inflow predictions, evaluation of the current state of MRWSS and development of recommendations for water reservoirs management pattern for a next operation term. The developed recommendations are regularly presented at the sessions of interdepartmental working group of the Moscow-Oka river basin authorities. Analysis of current hydrological state is provided on the base of GIS-technologies. Water inflow is calculated by ECOMAG hydrological model describing the full hydrological cycle of the Moscow River watershed. The technique for prediction of water inflow to reservoirs, based on use of a set of weather scenarios, is presented. Water regimes for 5 water reservoirs and downstream branches of the Moscow, Ruza, Ozerna and Istra rivers for a next planning term, are developed with use of VOLPOW water resources system simulation model. Finally the ways of improvement of the discussed DSS for Moscow River water supply system management are proposed.
