Waterless Composting Toilets New Zealand.
Nature, at its best.

Every day, New Zealanders flush millions of litres of pristine drinking water away — along with valuable nutrients that could enrich our soil — down the drain.

WCTNZ® specialises in practical water, sanitation and wastewater systems — from waterless composting toilets and water-free urinals to greywater reuse, wastewater treatment, grease management, pump stations and public and commercial infrastructure.

We help homeowners, businesses, councils and project teams choose systems that conserve water, recover value where practical, protect downstream infrastructure and keep essential services working where conventional plumbing is unavailable, impractical or simply not the best fit.
