Recent studies have shown that several structures and equipment are in need of upgrades, rehabilitation, or replacement. Major improvements needed include: anew headwork structure; new fixed film reactor; modernization of the electrical distribution system; new primary clarifier; modification to various structures; implementation of a flow equalization system to manage high flow events; and enlargement and modernization of the administration/control building.
