The Last Word: don’t just take our word for it “Compass Group has been providing facility management to numerous mine sites across the state for  over 30 years now and has, as a consequence dealt with many suppliers. One supplier stands out providing us with more products and widening their scope to us every day and that is Sigma Chemicals also known as Sigma Pool & Spa Supplies, with their head office based in Balcatta WA.   Sigma’s core line was initially everything to maintain the pool and spas, from chemicals to equipment, cleaners and now literally everything required in / around the pool / backyard, including compliance signage, bunding, chemical neutralisation and much more. Their inventory line today is very vast and now includes water treatment chemicals, testing equipment meters, reagents and RO consumables.  Some of our enquiries have been for pre-fab saunas to windsocks and they never cease to amaze us by sourcing, supplying and with their professionalism and far superior service.   One of their main strengths is understanding our complex business which evolves around  logistics and their appreciation of the issues on  sites, in particular those in remotes areas as this  sets them apart from other suppliers. Sigma’s customer service  and their technical support  is of the highest standard.”   Priyantha Perera Supply Chain Manager   – Non Food & Beverage Categories COMPASS GROUP (Australia) PTY LIMITED
