The LittaTrap™, made of plastic, is lighter, more flexible and costs less than the Enviropod®. The LittaTrap™ fits underneath the grate in the catchpit, and a mesh screening bag attached to brackets collects and retains the litter while letting water flow through. The LittaTrap™, which has a flow diverter seal and overflow bypass, can easily be lifted out by hand and emptied by anyone, and has wider market appeal.
During an 11 month trial – when a LittaTrap™ was inserted into a catchpit on the corner of Beresford St and Hopetoun St in Auckland – Stormwater360 captured 10.72kg of gross pollutants. These included 2000 cigarette butts, glass shards, wine corks, bottle caps, straws, wrappers, cans and plastic – some of them entering the catchpit via the large kerb entry slot rather than through the grate.
The LittaTrap™ earned Stormwater360 a New Zealand Innovation award in 2016, winning the Innovation in Sustainability and Cleantech category. The evaluator said: ``Great idea. The product is light, cheap and easily transportable which are all the key attributes as you develop your export market. LittaTrap™ protects our pristine oceans from waste, meaning consideration could be given to offshore licensing manufacturing agreements.’’
Stormwater360 listened. The Auckland company is negotiating a licence agreement with leading American firm, Contech Engineered Solutions to distribute the LittaTrap™ through United States, Canada and possibly Mexico. Stormwater360 also has an agreement to distribute Contech products in New Zealand.
"We are looking at up to 20,000 (LittaTrap™) units a year to United States and Canada – Contech is one of the largest stormwater treatment providers in the world,’’ says Hannah.
