Private water supplies provide ~3% of the Scottish population with their main source of drinking water. Many more people encounter private supplies when they stay in holiday accommodation and visit the more remote parts of Scotland, although PWS can be found in urban areas. The quality of these supplies is variable; many have adequate treatment and are well managed, but others present a risk to health due to the quality of the raw water and inadequate, or absent, treatment. For many communities relying on water supplies outwith the public distribution network it may be difficult to afford the capital costs required for improvement.
Restoration of river habitats by restoring physical habitats offers significant opportunities for improvements to biodiversity. To date in the UK and Republic of Ireland (RoI) there have been many different examples and types of restoration work undertaken. Despite this progress there remain issues relating to the quality of the evidence base for restoration, its implementation and its promotion as a viable strategy to improve river biodiversity, ecosystem status and maintain the key services that we rely on.
To help promote river restoration throughout the UK and RoI, a three-phase project is being carried out with the support of the International Union for Conservation of Nature (IUCN) National Committee UK (NCUK). Phase 1 reviewed the literature on river restoration (Ecus Ltd., in press). As part of the second phase of the project, a workshop featuring the combined expertise of specialists in river restoration was held. The findings from the Phase 1 report and the workshop will feed into an accessible report that will review the state of river restoration and its role in supporting biodiversity and ecosystem services and make recommendations for its future implementation.
CREW Annual Report 2013-14
CREW’s role is to support staff in SG, SEPA and Scottish Water (our end users) in their work to develop and implement water related policy in Scotland. As policy needs evolve, CREW also continues to evolve.
Spatially distributed modelling in support of the 2013 review of the Nitrates Directive
This report summarises the work undertaken at the James Hutton Institute of a modelling analysis of nitrate loads across Scotland as one stream of evidence to help underpin the NVZ review being undertaken by SEPA for the Scottish Government. This modelling work formed part of the core RESAS funded research.
This report responds to a CREW call down request submitted by Scottish Water to support the establishment of a pilot Water Restoration Park at a waste water treatment works (wwtw) to reclaim, recycle and market the waste water. The research sought to investigate potential locations to pilot a Water Restoration Park, regulatory frameworks and potential markets for the recycled water.
CREW Annual Report 2012-13
Scotland's Centre of Expertise for Waters, CREW, delivers objective and robust research and expert opinion to support the development and implementation of water policy in Scotland. During 2012-13 CREW has supported policy teams working on Hydro Nation, flood risk management, catchment management and the Water Framework Directive, drinking water and waste water services, as well as wider policy.

Surface water flood forecasting for urban communities: A Review
In urban areas, the impacts of surface water flooding can be very severe as such environments are generally densely populated and contain vital infrastructure. In recent years there have been regular occurrences of urban flooding in many parts of the UK with surface water flooding accounting for approximately one-third of flood risk from all sources (Houston et al., 2011). Within Scotland, the National Flood Risk Assessment (SEPA, 2011) estimates that around 125,000 properties are at risk of flooding from all sources and that surface water accounts for approximately 38% of the predicted impacts. Modelling, and real-time forecasting, of urban flood inundation is therefore increasingly relevant given the magnitude of potential loss and disruption.
This project aimed to assist SEPA in increasing its capabilities through developing an appropriate modelling methodology for surface water flood forecasting that could be operated in real-time. The Commonwealth Games in Glasgow (July 2014) offered a suitable opportunity to test the methodology. It provided a real situation where the risk of flooding was considered a major concern to strategic operations and where a forecasting system could be highly beneficial for the emergency response community.
Optimising Water Framework Directive River Basin Management Planning Using an Ecosystem Services Approach
This project was undertaken for the Scottish Environment Protection Agency, via a request to the CREW call down service as part of a range of SEPA initiatives under their Embedding Ecosystem Services work stream. The objective of this report is to review the process of River Basin Management Planning and identify how and where an Ecosystem Services Approach might assist SEPA in improving their delivery of the Water Framework Directive.
Natural Flood Management in the context of UK reservoir legislation
A short policy paper has been requested by Scottish Government via the call down service, detailing the issues managers come up against when implementing NFM in relation to UK reservior legislation. Information is sought on whether these issues still apply under the new Reservoirs Act.
