Aquarius Watermaster supplies the German designed Graf Li-Lo Underground tanks. These tanks are now manufactured in Australia to the highest standards. Their low profile means less digging than alternative tanks, and they do not require concrete ballast. The tank is available with a PE childproof pedestrian lid as standard or an extension riser and a trafficable lid as an optional extra. Link tanks together with the Graf proprietary seals to increase capacity. The telescopic extension riser adjusts from 220 to 700mm in height and is required for the cast trafficable lid.
