To Tatou Vai is the company set up to run the new, multi-million dollar, water system on Rarotonga in the Cook Islands.
It has recently initiated an environmental impact assessment (EIA) on the use of poly-aluminium chloride, which it wants to use to help remove solids and sediment from the system's settlement tanks.
This work is being undertaken by environmental engineers, Tonkin and Taylor.
Environmentalists are pleased an EIA is being done but concerned the company's brief is not to look beyond the use of poly-aluminium chloride.
The environmentalists have also long been concerned at government plans to use chlorine to purify the water system itself, when they say there are other, more benign, options available.
Don Wiseman spoke To Tatou Vai chief executive Brent Manning and began by asking about the EIA on poly-aluminium chloride.
