The City of Humboldt's lagoon system is nearing it's capacity to serve residents.

Last night at council's lone July meeting consultants from Catterall and Wright made an hour long presentation detailing the current and future state of the sometimes smelly infrastructure.

But what about the cleaning of the lagoon that took place a couple years ago, Director of Planning and Engineering Peter Bergquist explains more.

"You clean it out, you give it more capacity so it can treat faster and better and have more holding time in the cell. We just primarily did the first cell that year which did have a lot of debris. It's subjective if it improved it or not, I would like to think it did because there was a lot of sludge in there."

"Basically the report came out with that we are nearing our capacity with the lagoon," Bergquist continued. "We're going to have to seriously start thinking about how we are going to expand it and/or replace it in the near future."

Bergquist says they will now begin a pre-design phase that will help outline a cost but the area of $10-$15 million was spoken Monday night.

Bergquist adds they would like a new system within five years.

The current lagoon system was constructed in 1961 just southeast of the city.
