Debris disks, the tenuous rocky and icy remnants of planet formation, arebelieved to be evidence for planetary systems around other stars. TheJCMT/SCUBA-2 debris disk legacy survey 'SCUBA-2 Observations of Nearby Stars'(SONS) observed 100 nearby stars, amongst them HD~76582, for evidence of suchmaterial. Here we present imaging observations by JCMT/SCUBA-2 and\textit{Herschel}/PACS at sub-millimetre and far-infrared wavelengths,respectively. We simultaneously model the ensemble of photometric and imagingdata, spanning optical to sub-millimetre wavelengths, in a self-consistentmanner. At far-infrared wavelengths, we find extended emission from thecircumstellar disk providing a strong constraint on the dust spatial locationin the outer system, although the angular resolution is too poor to constrainthe interior of the system. In the sub-millimetre, photometry at 450 and850~$\mu$m reveal a steep fall-off that we interpret as a disk dominated bymoderately-sized dust grains ($a_{\rm min}~=~36~\mu$m), perhaps indicative of anon-steady-state collisional cascade within the disk. A disk architecture ofthree distinct annuli, comprising an unresolved component at $\sim$ 20 au andouter components at 80 and 270 au, along with a very steep particle sizedistribution ($\gamma~=~5$), is proposed to match the observations.
