The IWS Group (Industrial Waters Solutions) is your business partner for environmental sustainability in the land and water spheres at industrial sites. Now into our third decade, our professionals pride themselves in their ability to provide comprehensive environmental solutions to industry throughout New Zealand.
The IWS Group comprises of three entities that work in a complementary way, with each entity based around the interests and skills of the owners with significant experience in assisting NZ industry to meet and exceed its environmental obligations.
At the start of the business in 1994, the focus was on waste/wastewater. Due to the changing environmental focus in NZ, our work involves the protection or improvement of the ‘waters’ (a term that is becoming widely used in regulatory circles) - stormwater, wastewater and to some degree potable/recycled water.
We have good working relationships with NZ’s Councils and Water Authorities. We are familiar with the various rules, regulations and Council plans that relate to the protection of natural resources. These are all parts of the practical application of the Resource Management Act (RMA) and its downstream plans and regulations. Our service is personal - the owners of IWS are the ‘workers’ and you will find us and our staff to be professional, personable and pragmatic in solving your issues.
There's a perfect solution to your trade waste or stormwater management needs. We're here to help you find it.
