Nelson含羞草研究社檚 public works director says the volume of a sewage leak into the Kootenay River on March 27 was 含羞草研究社渘egligible.含羞草研究社�

In an April 4 news release, Charlie Henderson said the leak occurred in a pipe that transports sewage from the city to the sewage treatment plant at Grohman Narrows. The pipe is located about 30 metres below the surface of the Kootenay River.

About one million litres of sewage per day leaked into the Kootenay River between March 27 and April 3.

含羞草研究社淔or context, the Kootenay River flow in this location is 36 million cubic metres per day,含羞草研究社� Henderson said. 含羞草研究社淓ven though the leak was minor, the City of Nelson, along with the co-ordination team, took this event very seriously.含羞草研究社�
