To do a replace-in-kind of our existing Evoqua OSEC P unit with the current model Evoqua OSEC L System. The current OSEC unit is failing and is not anticipated to last reliabily for another year of operation. The replacement is intended to be an interim hypo solution at Water Station 15 - anticipated to last approximately 3-4 years until a larger treatment upgrade project (new deeper production wells, Iron/Managense treatment vessels) is started. Rather than invest in a signficant onsite hypochlorite generation system overhaul now, water engineering recommends installing a quicker, cheaper replacement now to address failing disinfection capabilities and include a full hypo system overhaul in the future treatment upgrades project.
