This is a full set of PowerPoint lectures for a course in Water Technology currently given at Trinity College, University of Dublin by professor N.F. Gray. The lectures cover all aspects of water and wastewater treatment and are available for use to lecturers or those interested in the subject. The lecture series is to be used in conjunction with the new textbook ?Water Science and Technology? (4th edition) published by CRC Press in 2017. Lecture 1 is an introduction to the water industry and covers the structure of the water industry, the water services cycle, water governance and the Drinking Water Directive. Water pricing, consumption, reuse and conservation are covered as is water demand management, the water poverty threshold and water stress threshold. The lecture include active links and structured reading. ; 1

ABSTRACTTaken in conjunction with the clauses added to the Water (Scotland) Act 1980 by the Water Act 1989 in respect of quality, as opposed to organizational terms, the introduction of the EC drinking water Directive1 and the proposed water quality Regulations2 represents the most fundamental change to Scottish water supply legislation since the Water (Scotland) Act 1946.The drinking water Directive1 was passed by the European Council on 15 July 1980, with the requirement for full compliance by Member States by 18 July 1985.Water Supply (Water Quality) Regulations for Scotland were circulated in draft form by the Scottish Development Department for informal consultation during September 1989. This had been preceded by informal consultation through the Convention of Scottish local authorities during the discussion stage of the UK Advisory Group on Drinking Water Regulations.This paper attempts to provide a simplified interpretation of the proposed Scottish Regulations on drinking water quality. It comments briefly on those requirements likely to have a significant impact on Scottish water authorities, including public communications, laboratory facilities, water treatment operational practices, and capital funding.

Abstract Background This article develop analyses water security in Mexico, a country where global environmental change requires social, political and economic actors to protect natural resources and ecosystem services in order to reduce the tension between anthropogenic demands and natural availability. The paper asks: How can overexploitation and inequality in the access and control of water be assessed using an integrated model of water management and how could the existing water resources in each river basin and aquifer be sustainably distributed by a new National Water Law that would encourage participation in order to overcome the conflicts over access to and control of water? Methods With a model of integrated water management the article reviews the current use of water among different social and production sectors. Results Agriculture still consumes 77 per cent of the water, especially in the arid north, an area greatly affected by climate change (CC). Industry uses ten per cent and domestic users thirteen per cent of water. The growing megacities are also overexploiting their aquifers, producing subsidence and water pollution together with changes in land use, thus reducing water infiltration into the aquifers during the monsoon. Regional and temporal water stress is further aggravated by unsustainable production processes, where mining and agribusiness hog the water needed by indigenous people and small farmers, forcing them to migrate to the urban centres or illegally to the US. Conclusions Within this arena of conflict in the field of water management, the article offers several guidelines for a sustainable and participative National Water Law. Food security, including dignified life conditions for the small-scale farmers in rain-fed regions affected by CC, could be achieved with small scale irrigation system in the Southeast of Mexico, where water is available for a second crop. Their sustainable agriculture and preventive management of water pollution by organic agriculture are central activity for conserving and restoring the natural condition of water infiltration. Without an integrated water management, reduction of soil erosion, early warning and resilience-building among the exposed people, Mexico will not reduce the existing and future threats related to global environmental change and particularly to CC.
