At the same time, the existing Fenny Bentley […]

Kelda Water Services Grampian (KWS Grampian) has a 28 year design, build, finance and operate contract with Scottish Water to operate and maintain four wastewater treatment plants serving the north east of Scotland; two sites in Aberdeen (Nigg and Persley) and two sites to the north (Peterhead and Fraserburgh). In addition to treating wastewater, KWS […]

The new intake works on the River Clodiagh near Holycross, County Tipperary is part of Phase 1 of the Thurles Regional Water Supply Scheme for Irish Water and will replace existing water supply sources that are vulnerable to contamination. The site is within a Special Area of Conservation with unusually high numbers of otters, crayfish […]

During two decades of working to legislated levels of security for physical access, the UK water industry has ushered a revolution in certified physical protection. While meeting this critical and immovable benchmark of resilience, solutions in AMP6 are pushing the envelope in design and functionality as never before. Security performance, of course, remains king, but […]

Trickling filters provide a reliable, efficient and cost-effective solution to almost any municipal or industrial wastewater treatment requirement – BOD removal, nitrification and denitrification. However, a trickling filter installation is only as good as the quality and reliability of each component part, particularly those which form the filter’s basic infrastructure such as the rotary distributor. […]

Scottish Water Horizons Ltd has created Scotland’s first ever full-scale test facilities for testing water and wastewater technologies in the Highlands and Central Belt.

UK water companies currently face many challenges, including the drive for improved phosphorus removal from a number of directives, in particular the Urban Wastewater Treatment Directive. There is also a growing requirement for increased nutrient removal, requiring low levels of ammonia, total nitrogen, BOD and suspended solids. In addition, there is the ongoing challenge to […]

When it comes to designing underground structures such as shafts, tanks and pipework infrastructure, it is essential that permanent works designers understand groundwater related issues. Their design typically includes measures to counteract buoyancy, to deal with lateral and vertical stresses imposed by groundwater, to provide waterproofing etc. However, the many risks caused by the presence […]

The physical security of assets on infrastructure sites is reaching new levels of sophistication and technical challenge. Utilities and other critical industries are systemically ‘hardening’ their operations, above and below ground, against identified risks of attack or infiltration by the criminal, saboteur or terrorist. Not only are the challenges growing in scale, clients are also […]

By 2050, total water demand in England and Wales is expected to increase by 35%. Per predictions by the Office for National Statistics, the UK population will reach 71.4 million by 2030, and 78.4 million by 2050. Climate change projections suggest summer temperatures will increase while rainfall will decrease leading to an 80% reduction in […]
