Regulatory Compliance Guarantee
Every service visit is conducted with regulatory compliance front of mind. FILTEC ensures your water treatment assets meet all relevant standards across New Zealand and Australia, including DWSNZ, HSNO, and regional discharge consents in New Zealand, as well as applicable Australian state and federal water quality regulations.
