The data used in this work were collected between the month of January and February of the year 2016 in the Lukaya River, located in the commune of Mont-ngafula, in the city province of Kinshasa. The DRC does not have a specific law or a water code and a clear national policy on integrated water resources management. Several projects exist and are underway with the support of German cooperation. The framework for the application of the laws of the related sectors is hardly applied this favors pollution, the irrational exploitation of fishery resources, inappropriate use of chemicals raising hygienic and environmental concerns. The objective of this work is to assess the environmental impact of the microbiological pollution of the water in the Lukaya River. The water samples were taken from the different sites in 600 ml plastic Canadian bottles and their analysis was performed at the INRB laboratory and the approach adopted in this work is that of membrane filtration which led to the following results: a high bacteriological concentration and numerous pathogens such as Escherichia coli, Proteus vulgaris, Enterobacter, Proteus penneri, Citrabacter and many other bacteria which testify to faecal contamination such as coliforms and faecal streptococci.

Abstract. Al-Ain is the second largest city in the Emirate of Abu Dhabi and the third in the UAE. Currently, desalination plants are the only source of drinking water in the city with an average daily supply of 170 MIG. Recently, Abu Dhabi Urban Planning Council (UPC) released Al-Ain 2030 Plan. Projects suggested in this plan, over and above the expected natural population growth, will certainly put additional stress on the water resources in the city. Therefore, Al-Ain city seems to be in urgent need for an integrated water resources management strategy towards achieving sustainable development. This strategy will contain three main components; namely, a Water Demand Forecasting Model (WDFM), a Water Budget Model (WBM), and a Water Resources Optimization Model (WROM). The main aim of this paper is to present the WBM that estimates all inflows and outflows to assess water resources sustainability in the city.

This paper discusses certain issues related to groundwater management within the context of the Brazilian national policy for water resources management. In order to investigate the importance of this water supply source, we interviewed groundwater users in the city of São Paulo, where some 57% of the total water supply comes from this source, and surveyed some of the factors affecting the use of this alternative. These include the existence of a good supply of groundwater, an inadequate public water supply system unable to meet user demands, the degradation of fresh water sources and the reduction in costs involved. Preliminary conclusions suggest the inadequacy of the present system of water resources management, which has not yet integrated the use of groundwater reserves into an overall national program for water resources management.

The City Blueprint of Amsterdam: an assessment of integrated water resources management in the capital of the Netherlands

The City

In this study the sustainability of integrated water resources management in Amsterdam has been reviewed using the City Blueprint approach. The City Blueprint® is a set of 24 dedicated indicators divided over eight categories, i.e., water security, water quality, drinking water, sanitation, infrastructure, climate robustness, biodiversity and attractiveness, and governance including public participation. In 2006 the various urban water-related services in Amsterdam were brought under one roof, culminating in the country's first water cycle company called Waternet. Waternet is responsible for surface water (rivers, canals, ditches and lakes), groundwater, stormwater, drinking water supply and waste water treatment. The city's unique water cycle approach has proved highly beneficial. Currently Amsterdam is the best performing city of the 30 cities assessed so far. This can be explained by: (1) a long-term vision and a multi-level water governance approach, (2) integration of water, energy and material flows (e.g., struvite production), (3) the entanglement between urban quality and water management, and (4) the transparent communication to and feed-back from customers, i.e., farmers and citizens. Surface water quality and biodiversity remain future challenges.

Legislative Framework

Environmental Impact Assessment (EIA) plays an important role in the framework of the efforts aiming at the formulation of a complete water resources management. In our paper this issue is examined in an integrated way. The following issues are particularly examined : the notion of the EIA in general, the assessment methods and techniques on the basis of the suitability of their use, the economic aspects, the Greek legislative framework, case-law positions in general as well as the action and the steering pattern of the Greek Public Administration concerning this issue. This paper presents some conclusions and proposals which are drawn by the aforementioned integrated approach.

The City

The City of Baltimore, Maryland is one of many US cities faced with challenges related to increasing potable water demands, diminishing fresh water supplies, and aging infrastructure. To address these challenges, the City recently undertook a $7M study to evaluate water supply and treatment alternatives and develop the conceptual design for a new 120 million gallon per day (MGD) water treatment plant. As part of this study, an innovative raw water management tool was constructed to help model source water availability and predicted water quality based on integration of a new and more challenging surface water supply. A rigorous decision-making approach was then used to screen and select appropriate treatment processes. Short-listed treatment strategies were demonstrated through a year-long pilot study, and process design criteria were collected in order to assess capital and operational costs for the full-scale plant. Ultimately the City chose a treatment scheme that includes low-pressure membrane filtration and post-filter GAC adsorption, allowing for consistent finished water quality irrespective of which raw water supply is being used. The conceptual design includes several progressive concepts, which will: 1) alleviate treatment limitations at the City's existing plants by providing additional pre-clarification facilities at the new plant; and 2) take advantage of site conditions to design and operate the submerged membrane system by gravity-induced siphon, saving the City significant capital and operations and maintenance (O&M) costs. Once completed, the new Fullerton Water Filtration Plant (WFP) will be the largest low-pressure membrane plant in North America, and the largest gravity-siphon design in the world.
