City Council members were given more information about the desludging project they approved last year for the wastewater treatment facility lagoons.
Council already approved a budget of $3-million, however it was noted there will be additional costs for the removal and reinstallation/replacement of the current aeration diffusers.
However, these extra costs are expected to still be within budget.
“There is going to be some work to be done, but the good news is it will be broken up to two contracts, and we will hopefully be able to stay within the original budgeted amount,” said Mayor Gerald Aalbers. 
The lagoons have not been desludged since the 1990s and are in need of the work.
“It does need it,” said Aalbers. “We know our retention time in our lagoon system is much below what we would like to see, and that results in some of the reasons we are having questions raised by the Water Security Agency, around our licensing that leads into the wastewater treatment plant. It’s all connected.”
Coun. Aaron Buckingham also brought up the discussion during the meeting on Monday about how long it’s been and questioned why it had not come up sooner.
“It’s interesting to note it was last done in 1990 with a shelf life of 10 to 15 years, maybe 20. We have 27 years, so I guess we have got some really good value out of that plant,” he said.
The $3-million needed for the lagoons is not part of the $80-million price tag for a new mechanical wastewater treatment facility. 
The city was granted a three-year extension from the Saskatchewan Water Security Agency and currently has been waiting for provincial funding to help with the costs of the wastewater treatment facility.
