The employee, who asked not to be named, said a tanker truck made between one and five trips a day to the pit that serves the city and is adjacent to the sewage lagoon.

"There was a treatment plant out there, but the gate was locked," the worker said.

The dumping continued until Christmas, when the tanker truck broke down. From then on the 1,000 litres of cow manure excreted each day was pushed out the back door of the barn, where it froze into a giant block.

The buildup was disposed at the dump earlier this summer. Under the agreement -- yet to be finalized -- between the dairy and the city, the city agrees to co-operate with the dairy in establishing a site for the disposal of manure.

City public works director Neil Jamieson said he could recall Tuaro being given permission to dump at Fiddler's Lake after a manhole they used on the site clogged.

Jamieson noted materials from other city businesses are deposited at the site, along Highway 3 past the golf course. He noted the territorial government is responsible for establishing and enforcing discharge guidelines.
