Kingspan Water Provides Rainwater Harvesting Solution for Defra Offices in Northumberland

Lion House is an ultra low-emissions office building, designed and built for Defra in Alnwick, Northumberland. The aim was to construct a building with the highest possible BREEAM rating. Kingspan Water was asked to design a suitable rainwater harvesting solution for the building.

Aston Clinton, United Kingdom, May 28, 2009 --(PR.com)-- Lion House is an ultra low-emissions office building, designed and built for the Department of Environment, Food and Rural Affairs (Defra), in Alnwick, Northumberland.

From the outset, the aim was to construct a building with the highest possible BREEAM rating. That included incorporating low energy technologies, responsibly sourced materials and reduced carbon emissions.

There was also the aim of minimising mains water consumption through low-water use fittings and rainwater harvesting systems.

The project’s M&E contractors Haden Young approached one of the UK’s leading supplier of rainwater harvesting equipment, Kingspan Water, to design a suitable solution for the building.

The Kingspan Water team worked closely with Haden Young to configure its Envireau equipment to meet the water consumption requirements for toilet flushing for Lion House’s 100 employees.

The agreed system comprises of a pre-tank filtration system, a 12,000 litre underground storage tank, an electronic control system and pump. The pump in the main holding tank delivers the water to a high level header tank in the building from where the water will gravity-flow to the serviced appliances.

The team calculated that the annual water consumption at Lion House will be around 469m3. Given the roof area of the new building, and the annual rainfall statistics for the region, it is estimated that the annual water harvest will be around 563m3.

In theory, therefore, all of the annual toilet flushing water is expected come from the rainwater harvesting system.

Gerry Quinn, product manager for Kingspan Water says: “Reusing rainwater presents savings not just for the environment, but also in terms of reduced water rates. At today’s water cost, we expect to see Lion House saving in the region of £800 per annum, so we would anticipate payback on capital investment in around 4 to 5 years.”

A spokesperson from Haden Young says: “We chose Envireau because, having worked with their team on a number of other projects, we have confidence in their harvesting system.”
