Watercare Services has hit back at a developer who accused it of charging too much for Auckland residential subdivisions.
John Redwood, Watercare spokesman, said the charges were fair and helped fund the network which faced huge costs.
"Watercare's asset management plan forecasts $5 billion in capital investment over the next 10 years. Capital investment has three main drivers: investment to renew or replace existing assets, investment to improve service levels, and investment to service expected growth in demand.
"Watercare has three sources of funding for this investment: charges on existing customers, new borrowings - essentially a charge on future customers - and infrastructure growth charges."
The organisation's financial strategy sought to balance the contribution from each of these sources so the costs were aligned with the benefits, he said.
