NEWS | PUMP, VALVES AND PIPEWORK Wavins solution cuts noise for luxury apartments SCOTTISH PIPERS CONNECT HOMES TO DISTRICT HEATING Rehau pipework distributes hot water from a biomass boiler Wavins AS+ range has been specified as a low-noise soil system for a block of luxury apartments in a mixed-use development in Hove, East Sussex. As well as apartments, the Tate Residences includes a bar-restaurant on the ground floor and a communal terrace overlooking Sussex County Cricket Club. In this mixed-use context, developer Roffey Homes had to overcome a key water management challenge dealing with drainage acoustics in a high-end development, keeping pipework noise to a minimum. Plumbing and heating specialist Woods Heating was brought in to advise and recommended Wavins solution. The AS+ range is designed to reduce the sound emitted from pipework significantly, according to Wavin. For example, airborne sound is lessened because of its high mass and wall thickness, while structure-borne sound is minimised by the low elasticmodulus of its flexible material. Wavins high-density polyethylene range was used in the buildings parking space, as the pipes and fittings are lightweight, durable and easy to install, according to the manufacturer. The products are fully welded, providing a system highly resilient to any unexpected knocks from HGVs, said Wavin, which added that it is easy to integrate with the AS+ low-noise system used elsewhere in the development. Rehaus Rauvitherm pre-insulated pipe has been specified for the district heating system at North Ayrshire Councils Flatt Road low-carbon housing development, in Largs, western Scotland. The flagship scheme of 122 new homes was connected to a nearby biomass plant for its heat and hot water using the pipework, which Rehau says offers minimal thermal losses and swift and safe installation. The Rauvitherm pipe was cut to length in the factory and shipped, with fitting and shroud kits, from Rehaus warehouse in Manchester. The company said its Everloc jointing meant the network could be pressure tested and operated at 70C straight after joint completion. Low-noise drainage was a key requirement for the Hove apartments C40 Cities confirms water-stewardship plan C40 Cities a network of mayors, of nearly 100 world-leading cities, collaborating to deliver the urgent action needed to confront the climate crisis has confirmed plans to support urban areas in improving water stewardship in the coming years. The initiative has provided details for the next phase of its Water Safe Cities work, which includes the creation of a Water Accelerator a platform through which cities can improve their pledges to safeguard water supplies and protect residents from flooding. The platform will also support cities to embed these pledges into their climate and urban planning approaches. The overarching aim is to help cities develop, implement and achieve targets based in science regarding water-related risks.
