Aquatech Solutions has introduced Aquaseal, a waterstop sealant designed to seal leaking structures and stop leaks instantly. The product expands 2000 percent in four to five seconds sealing leaks in flowing water.
Aquatech Solutions is a specialist engineering company offering pipe network rehabilitation systems. Aquaseal is commonly carried and used by first response teams for stopping toxic leaks into the environment. It is designed to permanently plug high-infiltration sources in all structures and will stop leaks in excess of 200 litres per minute.
Aquatech Solutions says one manhole leaking 10 litres per minute will leak 15 cubic metres per day. If the cost of treating wastewater is $2 per cubic metre, this single manhole with a 10 litre per minute leak will cost more than $10,000 per year. In Wellington, construction, maintenance and management firm City Care is already using Aquaseal on all of its first response vehicles to stop sewage leaks into waterways.
Other local government bodies using the product for their drainage networks include Wellington Water, Marlborough District Council, Auckland Council and Porirua City Council.
