An Oamaru couple disgusted by the ''putrid'' smell of effluent they say is being spilt by stock trucks on an access way to a service station next to their property wants the issue addressed.
Gordon and Valma Johnson have lived in Regina Lane, directly behind the Caltex station in Thames Highway, since they retired to Oamaru in 2001.
The couple said more than a decade of no issues related to the operation of the service station changed when redevelopment at the site, owned by Oamaru-based McKeown Group, started in 2017 and was completed earlier this year.
Part of the redevelopment involved the construction of a driveway bordering the fence line of the Johnsons' property, which is accessed around the clock by heavy vehicles.
Mrs Johnson said some stock trucks that used the access way had spilled effluent, which had caused a ''dreadful'' stench and posed a health risk.
