A pilot project conducted in Saldus, Latvia, aims to collect surface runoff and treat it to make it usable for various municipal purposes – including watering municipal greenery and operating a public fountain currently under construction that may also be used by children as a play area. Before being collected in an underground storage tank, the stormwater is treated in multiple stages in order to purify it for these purposes: after flowing through an oil and sand separator, it is disinfected using UV light and conducted through a water treatment system (chlorination).
Moreover, educational elements will be furnished at the public fountain on Kalpak Square, which is to be supplied with this water. These are intended to inform people about the consequences of climate change and the need for new water management.
