This invention relates to a wall mountable drip tray (1) of the type comprising a mounting plate (5) for mounting the drip tray to a wall, a liquid reservoir (7) extending forwardly from the mounting plate and in which the wall mountable drip tray further comprises monitoring equipment (9) including a proximity sensor (8) for detecting an individual or equipment in the vicinity of the drip tray. The monitoring equipment further comprises a transceiver for communicating with one or more of a remote control unit (23), a fixed network unit (35) and a mobile network unit (37) of a monitoring system (21). By providing such a wall mountable drip tray, existing hand hygiene infrastructure, specifically wall mounted antibacterial liquid dispensers, in an installation can be incorporated into a new monitoring system and will not become obsolete.
