    Notes: Article 14 of the Water Framework Directive requires member states to demonstrate that they are enabling increased public participation in water governance issues at the river basin level. Yet little research has been conducted to understand in what regard water governance bodies are held by the public. In particular, few studies have concentrated on which water resource management issues concern consumers at the catchment and sub-catchment scale within England and Wales. A household study was conducted in 2003 along the River Nene catchment in the east of England to understand in more detail the range of these consumer perceptions and attitudes at different spatial scales, focusing on water resource management issues such as flooding, sector performance and policy making. The results of the survey demonstrate that formulating policy at the catchment scale does not always capture the diversity of opinion or the range of legitimacy issues which concern consumers at the sub-catchment level. The paper concludes that public participation initiatives may be improved by paying closer attention to the various legitimacy concerns at the catchment and sub-catchment scales.

    Notes: The effect of controlling the pre-coagulation regime on downstream ultrafiltration of raw upland waters has been investigated. It has been shown that zeta potential can be used to detect changes in the coagulation process and hence to determine appropriate dosage levels. This is important, as incomplete coagulation has a detrimental effect on ultrafiltration membrane performance, particularly in terms of fouling caused by excess iron. Submerged hollow-fibre membrane units yield superior performance with pre-coagulation and sufficient slow mixing of coagulant guarantees high permeate flow recovery after backwashing. Fouling by natural organic matter can be remedied by conventional cleaning techniques. However, fouling due to excess iron can only be removed by heating the cleaning solution. The associated costs are thus two-fold; that of excess coagulant and that of cleaning.

    Notes: Llangefni WwTW receives discharge from the rural town of Llangefni and the local industrial estate and to date this is the first and only BNR plant in Wales. The consents from March 2003 included a reduction in ammonia (NH4_N) to 1.5 mg/l, suspended solids to 20 mg/l (SS) and Biological Oxygen Demand (BOD) to 7 mg/l and included a new Phosphate (PO4_P) standard of 2 mg/l. The process selected to meet the new consents was Biological Nutrient Removal (BNR) and was unusual as it was for a small, rural wastewater treatment plant that receives about 26% of its flow from an industrial estate.During commissioning, the plant produced an average phosphate concentration of 1.0 mg/l and an ammonia concentration of 0.7 mg/l. It was confirmed that to achieve consistent phosphate removal a BOD:P ratio greater than 20:1 is required along with a high VFA (Volatile Fatty Acids) concentration of 200–300 mg/l.

    NUMERICAL SIMULATION OF SALINE UPCONING IN THE PLEISTOCENE AQUIFER OF JERICHO AREA (2005)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The existence of fresh groundwater overlaying saline water in groundwater systems is widespread in many inland aquifers and most coastal aquifers. The Jericho district suffers from the phenomenon of saline upconing. The Pleistocene aquifer, which is the main source of water supply for irrigation in the Jericho district, comprises a layer of salt water covered with lenses of fresh water. It appears that drought and heavy exploitation from Jericho wells are the main reasons for the saline upconing problem in the Pleistocene aquifer. The objectives of this research were to (a) investigate the saline upconing phenomena and (b) provide recommendations for control of the fresh and salt-water mixing in the Jericho aquifer underneath a skimming well. A model, which coupled density-dependent flow and solute transport, was used to simulate movement of the salt water under different hydrogeological and operational conditions. Results from the simulations showed that location of the screen has a strong impact on salt-water movement in the well. Reasonable control of saline upconing was observed when the screen was placed against the gravel layers.

    Notes: A computer model was developed to evaluate the impact of various technologies for water conservation in domestic households, in terms of the Impact on the operation of downstream infrastructure. These technologies, which include (a) low-flush toilets, (b) greywater re-use, and (c) re-use of rainwater from roof runoff for toilet flushing, were compared using indicators of sustainability to measure water consumption, sewerage-system operational performance and process treatment efficiency. The results demonstrated that rainwater re-use is potentially the most sustainable strategy in terms of the benefits associated with water conservation and reduction in sewage discharges from combined-sewer overflows (CSOs). The benefits were observed without the problems associated with increased sedimentation in sewers during dry weather, associated with other water-conservation strategies such as reduced-flush toilets, greywater re-use and the resultant increase in pollutants from CSOs during wet weather.

    Notes: The east and south-east of England has the lowest rainfall in the UK, water resources are limited and under pressure through increased demand and population growth. In the late 1990’s AW Innovation (the AW R&D group) developed a process that could produce high purity water from sewage effluent using membrane technology. In late 1999 Texas Utilities (TXU) signed a contract with Alpheus Environmental for the supply of high purity water for Peterborough Power Station. The novel treatment plant was built in 1999 - 2000 and opened in July 2000 by the Mayor of Peterborough. This paper is a review of the plant design, the technology used for the treatment process and a summary of the first four years of operation.Changing from potable water to high purity water produced from sewage effluent has brought significant benefits for the power station resulting in higher purity steam generation while reducing chemical, power and effluent discharge costs. In addition Anglian Water is now saving 1,000 m3/day of potable water.

    DIFFUSE POLLUTION - WHAT IS THE NATURE OF THE PROBLEM? (2005)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This paper considers recent developments in the understanding of diffuse pollution, its generation, transport and impacts. The relative importance of diffuse sources to total pollutant loading must be identified in order to develop appropriate strategies for management.Research has indicated that individual diffuse pollutants respond differently to changing flow conditions and that there is a widespread misconception that higher flows are associated with lower pollutant concentrations. Evidence is presented to highlight this discrepancy and a rationale for load assessment is presented. The implications of this for monitoring within the context of the EU Water Framework Directive are discussed as are the implications for the mitigation of diffuse pollution.

    Notes: Some landfill site operators use wastewater treatment plants for the discharge of complex leachate waste. However, for the water company involved in managing the wastewater plant, leachates can pose a problem to the quality of the effluent, due to the high levels of Chemical Oxygen Demand (COD), ammonia and inorganic metal constituents. Electrochemical oxidation of landfill leachate has been successfully used by researchers(1,2,3,4) with current densities of 5 to 100 mA/cm2. A new laboratory system has been developed which utilises a low current density of 2.42 mA/cm2 and the performance has been evaluated with synthetic and ’real’ landfill leachates from 2 wastewater sites.This system reduces COD of synthetic mixtures by 58%, with complete removal of ammonia. For real leachates, 5 out of 8 samples resulted in ammonia reduction, with 2 samples experiencing approximately. 60% COD reduction. Power costs for treatment have been determined and the potential for a full-scale installation considered.

    Notes: The implementation of the EU Landfill Directive in the UK demands high rates of recycling by local councils and regional waste authorities. Currently recycling is either carried out at cost intensive materials recycling facilities (MRF) or through separate collection services. Collection of separate materials is undertaken in inner-city boroughs of London mainly through bring-banks, which are often severely contaminated, and by kerbside collections from street properties. However, the provision of door-to-door collections in inner-city estates has not been widely used yet, because of the lack of data to assess the potential and costs of such recycling services. In this paper a detailed assessment of a pilot door-to-door recycling service is presented. This pilot was carried out for a year by a local not-for-profit company in two inner-city estates in the London Borough of Tower Hamlets (LBTH).
