Hydr8 will be sold in 500ml screw-cap and 500ml sports bottles, as well as in six-packs and five-litre formats.
It will be sold primarily through specialist food service distributors and cash-and-carry outlets, and is geared towards cash-conscious customers.
Highland Spring said Hydr8 is a naturally sourced British water, produced in Glasgow, which promots the eight-glasses-a-day regime.
The launch of Hydro8 will broaden Highland Spring's portfolio, which also includes the upmarket Gleneagles mineral water brand, and its core Highland Spring brand.
