Filter Sand

Irwins are Irelands Number 1 supplier of water filtration sands. We currently hold the tenders for supply of filtration sand for Irish Water and NI Water.

Our sands are high silica and are washed, hydrosized and dry screened to ensure that they meet the exacting standards as laid out by the Water Authorities and Regulators throughout Ireland. Irwins are proud to have been the premier supplier into this market for the last 30 years.

We supply sand for traditional slow sand filters plus a large range of filtration sand which can be used in potable water applications. Our sands are also widely used in filters in swimming pools, in the food and drinks industry and the pharmaceutical industry. We also supply filtration sand for use in Wastewater Treatment Plants and for Sand Polishing Filters. Our standard list of filtration sands are as listed below.
