Background: Better water quality, improved sanitation and sound water resource management will improve public health and economic development in low-income countries. Water safety plan-based risk assessment and risk management from catchment to consumers are the modern and efficient approaches to safe drinking water supply established by World Health Organization. Thus, this paper aimed to assess risk from catchment level to consumers in the community of Brikama. Methods: This study report assessments of risk or hazards from catchment to consumers in Brikama Water Treatment Plant (BWTP), West Coast Region, The Gambia. The various means of data collection used include water quality monitoring, visual field inspection and questionnaire survey to explore data on where the water supply system goes wrong from catchment to consumers, so as to provide an improvement plan. Results: Overall, the day-to-day administration of services at BWTP was very impressive. The fencing of all the 17 boreholes at catchment sites has drastically reduced the risk of contamination including treatment systems and distribution lines. There are less risks observed and constant monitoring of the system was ensured. However, at the consumer end, there are some risks with poor practices associated with water handling, storage and hygiene measures at the household level. Some still use some unclean 20-liter containers to store water and indiscriminately kept drinking cups on the floor and unclean surfaces, and 50% lacked WASH knowledge related to water treatment, such as boiling and filtration at households. The overall perception of water storage, sanitation and hygiene practices could be rated moderately good. Conclusion: The overall findings of this study have shown tremendous achievement in the government's commitment to providing potable water to the people in Brikama Local Government Area. WASH education in the study area is recommended to avoid waterborne disease infections.

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 Diagnosis

Water supply systems represent one of the main components of municipal infrastructure. The operation of these systems is a complex task due to the several variables that interfere with the water distribution dynamics. The objective of the work was to obtain a diagnosis of the operation of part of the water supply system of Campina Grande and to find the main limitations and potentialities of the system infrastructure. The system supplies water to several municipalities, serving an urban and a rural population of more than 500,000 inhabitants. For the operational diagnosis, hydraulic modeling was done using the Epanet 2 simulator. The operation was modeled from the water treatment plant to the pressure zone 2 of the Campina Grande system. Cadastral surveys of the water network were carried out, field surveys and interviews with the operators. Based on the scenarios analyzed it was possible to conclude that zone 2 of the supply system has little margin for increase demand , around 10%, that the system can not work outside the peak hours and the energy cost is mainly generated by the station of water treatment. In order to improve the vulnerability reduction operation, investments are required in the physical structure of the system and in monitoring and automation.

AbstractTo elaborate efficient and economical water supply systems is one of the main objectives in the sanitation companies water system projects. In order to address the challenges faced in reaching this objective, this study aims to identify, first, the relation between the percentage of non-conformed samples in treated water and the inefficiency of the filtering units installed in the water treatment plant, and second, if, by drawing the consumption variation curve it is the most efficient way to predict the storage tanks volume—comparing necessary capacity, determined by the consumption curve, and installed capacity, predict by the outdated Brazilian normative. In order to reach answers for these two questions, this study measured the operating efficiency of the treatment plant as well as have set a quantitative comparison between the two dimensioning criteria for storage tanks volume present in the literature. As a result, the analysis provided the authors to detect a focus of contamination in the single-layered filtering units, limited by the filtering capacity of 2–6 m3/(m2 day), whilst operating at 333.13 m3/(m2 day). As well as to detect by the drawing of the consumption variation curve an oversize of 68% and 60% in the dimensioning of the studied storage tanks. With the results provided by this analysis approach, it was possible to efficiently detect and correct critical impairments in the treatment phase and to conclude that a long-term analysis should be drawn in order to affirm if the consumption variation curve is the best design methodology for the reservoirs.

Biological Nitrification

The implementation and evaluation of biological nitrification as a possible treatment option for the small-scale drinking water supply of a rural Upper Austrian community was investigated. The drinking water supply of this community (average system input volume: 20 m3/d) is based on the use of deep anaerobic groundwater with a high ammonium content of geogenic origin (up to 5 mg/l) which must be treated to prevent the formation of nitrites in the drinking water supply system. This paper describes the implementation and operation of biological nitrification despite several constraints including space availability, location and financial and manpower resources. A pilot drinking water treatment plant, including biological nitrification implemented in sand filters, was designed and constructed for a maximum treatment capacity of 1.2 m3/h. Online monitoring of selected physicochemical parameters has provided continuous treatment performance data. Treatment performance of the plant was evaluated under standard operation as well as in the case of selected malfunction events.
