Refurbishment
Bath Spa station Oxford Architects completed a refurbishment of Bath Spa in 2012 for Network Rail, which encompassed refurbishment of waiting rooms, front canopy and stonework, stairwells and lighting. In addition, it undertook a refurbishment of washrooms (including male/ female and disabled facilities) on platforms 1 and 2 for First Great Western. This involved replacement of all sanitaryware, as well as refurbishment of wall/ floor tiles and cubicles. Green Building Store supplied ES4
WC’s a siphon flush system with a low flush of 4 litres per flush, and with public ‘palm push’ button, and the Airflush urinal system for the project. Alistair Jackson at Oxford Architects
a week. For some offices and buildings, this could mean that up to 76 per cent of flushing could occur when the building is unoccupied. Flush control technologies are now
available for urinals including: timer controls, infra-red or ultrasound sensors. Some flushing systems respond to variations in water pressure or flow, for example when taps are used. However, to maximise water-savings,
specifiers often opt for waterless urinal systems. Waterless urinals also offer the advantages of being more vandal and frost- proof and less prone to blockage. However, instead of using water, many use disposable cartridges or oils, which themselves can involve significant environmental and maintenance costs. With such products, according to the Water Regulations Advisory Scheme, ‘It is necessary to evaluate the cost of cleaning chemicals and
manpower against the savings from fewer water fittings and the use of water.’ A recent development has been the Airflush urinal system which uses neither water nor consumables. Instead, the system combines the use of a low energy electric fan which removes odour by maintaining a flow of air down hygienically designed urinal bowls.
Taps Taps can be fitted with spray inserts and aerators, which help reduce water use while providing sufficient flow for hand washing - a 1.7 litre spray is ideal for washrooms. To save water without having to replace taps, in-line flow regulators limit flow instead in the supply pipe and can limit the maximum flow to four litres per minute.
Electronic sensor taps and timed turn-
off push taps can also prevent wastage and flooding from taps being left running.
said: ‘We chose the ES4 WC and Airflush system because of their robustness and ability to work well in high usage situations. Our clients First Great Western were very keen on reducing water consumption and both products offered significant water savings. Feedback on the products has been positive and we are planning to use the ES4 WC’s at a forthcoming refurbishment of Bristol Temple Meads station.’
Ormskirk Station The Grade II listed Ormskirk was neglected and under-utilised, with inadequate toilet facilities, comprising just one shared male/female toilet in poor condition. SBS Architects undertook a complete refurbishment and internal remodelling of the station building on behalf of MerseyRail and Lancashire County Council, completed in summer 2009. The refurbishment won a National Railway Heritage Award in 2011 and a Station Development Award in 2010. The station’s new toilet facilities
comprise five toilets, including disabled facilities. SBS Architects specified water- efficient ES4 WC’s from Green Building Store for use in the washrooms. Lancashire County Council and MerseyRail were very supportive of the eco features at Ormskirk and endorsed all measures that would help reduce long-term operational and maintenance costs.
