WRAS (Water Regulations Advisory Scheme) contributes to the protection of public health by preventing contamination of public water supplies and encouraging the efficient use of water. The company recently has issued to Isoil Industria the WRAS Material Approval for the Rilsan lining. This material complies with the high standards set out by water regulations promulgated in 1999 in the United Kingdom: they set the rules and the test methods to evaluate the materials in order to assess their effect on organoleptic (such as taste, odour and colour) and chemical characteristics of waters intended for human consumption.
Here you can find the WRAS Material Approval for the Rilsan lining.
For other linings, Isoil Industria has got the NSF-61 Approval, required in the USA market. Visit the website www.isoil.it.
