A nozzle for spraying deicing liquid onto surfaces lies flush with surfaces to prevent obstruction of surface treatment. The nozzles may be integral nozzles formed with the surface and may have relief channels designed to spread spray into a stream or a flatter pattern by adsorption of the streaming spray to the relief channel. The nozzles may be adapted for mounting and have an alignment base. An integral check valve and a flow switch are provided in the system. Additionally, either combined with the movement of the nozzle assembly or independently, a pump is regulated to vary the substance flow and pressure to get the desired spray distance and droplet size. Different programs may drive the nozzle and pump assembly depending on the target surface and rheology of the substance under the conditions to be sprayed. The nozzle may be of composite material, stainless or other metal, cast or molded. A groove at the base of the nozzle accommodates epoxy used during installation and aids in forming a tight bond between the nozzle, epoxy, and pavement. An inlet permits supply of anti-icing liquid to the nozzle, which is suited for varied applications. A flat surface installation guide protects the installation gig from debris, glue, epoxy, etc. The gig is temporarily affixed to the device to be mounted flush with the pavement. A streaming or fan-shaped spray nozzle is aimed in such a manner that the deicing liquid covers entire targeted surfaces. The device includes sensors and instruments to measure surface conditions and events. Wear indicators permit easy identification of worn out nozzles.
