The wastewater extractor pump noise ongoing since Thursday finally stopped at noon today. Geoff Cunningham from Harvey's Marine is very helpful on the phone, and seems intent on finding some solution. He reports that the noise comes from one particular Pardy pumper truck, their biggest and noisiest, which was used for some extra deep cleaning of a supply vessel. Normally they use smaller pumper trucks for regular extraction; this one is employed from time to time. He has apparently received various complaints from residents' in the past days, and knows that it makes an objectionable racket. He parked a couple of containers around it Sunday hoping to block the sound, but it made no difference. He's hoping to find a way to minimise it in future. Good luck to him.
