Chute rooms drive odour through the whole tower
A chute room on each level shares a shaft with every other, and odour generated at any point travels. Residue on a hopper door, spillage on a room floor and material caught at the hopper opening all contribute continuously. Because each room is small and rarely visited by management, the accumulation is easy to miss until it becomes noticeable in a corridor.
Frequent short attendances hold these rooms far better than occasional detailed ones. Wiping the hopper and its door, washing the floor, and clearing anything caught at the opening takes a few minutes per level and prevents the condition that generates complaints. The scope should state the frequency per level rather than describing the rooms collectively. Recording the per-level frequency in the schedule, rather than describing the rooms as a group, is what ensures every level is actually attended.
