Resolis Primary School

Constructed Wetlands: Groundwater Treatment Plants (GWT)

Created at: 25 Aug 2016

Description

NeedThe Highland Councilconstructed a school on the Black Isle near Cullicudden known as ResolisPrimary School. Sewage effluent from the school was to pass through a septic tankand secondary treatment system prior to discharging back into the environmentvia a water course. The discharge consents for the secondary treatment elementwere not excessive and the council were keen to use as sustainable treatmentsolution as they could. There was some land available towards the south ofthe school beyond the playing field where the septic tank was to be situated.<br><br><br>Solution<br>The discharge permit did not specify an ammoniaconsent and so a two horizontal subsurface flow wetland treatment system wasselected as the most technically and economically effective solution atResolis. The available land dictated that the beds should lie end to end butoperate in parallel. A connection was made to the septic tank discharge and asplitter chamber was constructed to divide the flow from the septic tanksequally between the two reed beds. Each bed was 200 m2 totalling 400m2. The reed bed was to also be an educational resource for theschool highlighting the use of sustainable technologies. It was, however,important to provide fencing around the system due to the proximity of theplayground to the treatment system. Access to the reed beds was only allowedunder close adult supervision.
