Abstract: A downpipe valve control system has a main body having an inlet and an in-line outlet configurable for fluidly connective installation as part of a downpipe. The main valve also has a main valve handle therefor operative between the inlet and the outlet. The system also has an attachable spigot having a removeable proximal cap interfacing a proximal port of the main body. The proximal has a diameter greater than 7 cm and a distal inlet port for a water hose can be connected to the proximal cap. The present arrangement can be used for cleaning gutters, flushing rainwater tanks and/or mitigating against ember attack.

Abstract: Methods and systems for clean-up of hazardous spills are provided. In some aspects, there is provided a system for burning an water-oil emulsion that includes an enclosure configured to hold a water-oil emulsion; one or more conductive rods disposed throughout the enclosure, each rod of the one or more roads having a heater portion to be submerged in the water-oil emulsion and a collector portion to project above the water-oil emulsion, wherein the collector portion is longer than the heater portion; and a delivery system for supplying an water-oil emulsion to the enclosure, the delivery system is configured to maintain a constant level of the water-oil emulsion in the enclosure as the water-oil emulsion is burned. The enclosure may further include one or more adjustable air inlets.
