Further investigation of the smelly green fluid problem in Whanganui has revealed the pipe is from the Landguard Bluff army barracks.
The smell was from wastewater discharge.
Whanganui District Council spokeswoman Cass Alexander said the council's building team "has been in contact with the army about this. The army has undertaken to maintain the current system and have its septic tanks emptied to prevent any further discharge, until a more permanent result can be achieved."
On February 25 the Chronicle reported that a putrid, green fluid was discharging into the Whanganui River.
The pipe runs under the unsealed road between the army huts and South Beach, and flows into the river.
