Kura Moeahu at Waiwhetu Stream.
A top water official in the capital is warning of the consequences if another major wastewater treatment plant in the city critically fails.
The Seaview plant in Lower Hutt has been plagued by stench issues in recent years, and its 18-kilometre-long sewage pipe into Cook Strait is leaking.
The pipe replacement could cost up to $1 billion.
Wellington Water admits the situation is unacceptable as it's forced to spill treated sewage into a stream that's sacred to local iwi - though it's adamant the plant can't fail in the same way as Moa Point did.
