Auckland Council's water and wastewater provider Watercare says it has reviewed its processes relating to new developments and connections to its network, to enable qualified contractors and consultants to self-certify their work.

Complaince statements will be introduced to provide a consistent system for ensuring all work carried out on Watercare's network meets its engineering standards.

Watercare says use of the statements will become mandatory from 1 July 2017. The four different types of compliance statements are available on the Watercare website.

“This review is about protecting our customers and enabling competent contractors and consultants to self-certify their work, which will largely remove the need for inspections from Watercare staff," strategy and general planning manager Martin Smith says.

“Accepted compliance statements will also give Watercare a legal avenue to claim costs from the responsible party when negligence is discovered, so that ultimately it’s not our customers who will bear the burden of this cost.”
