What’s Happening Tonight?

The Region of Waterloo is developing a

Biosolids Strategy. At this event you will have an opportunity to: • Review what we are doing with biosolids today • Learn about alternatives for managing this material • Understand how we will be making a decision • Fill out a survey • Provide feedback

Tonight’s Agenda Open House • Have a look at the project information on display and chat with the Project Team. • Provide input on the strategy alternatives • Provide input on the criteria used at each of the two steps in the decision making process

Work will be completed to meet the requirements of the Environmental Assessment Act as outlined by the Municipal Engineers Association Municipal Class Environmental Assessment (Oct 2000, as amended in 2007, 2011 and 2015) process.

Biosolids in Waterloo Region Today When you finish doing your business, that’s when the Region of Waterloo gets busy doing its business. The diagram below describes how biosolids are managed in the Region today. Over 180,000m3 of wastewater is processed every day...

13 Wastewater Treatment Plants Clean water is discharged to the river

...equivalent to

535,000 Residents... and growing!

72 Olympic-sized swimming pools! Over 1,550 tonnes of liquid biosolids are generated daily. This means a lot of processing, transport, and management throughout the year (equivalent to the weight of approximately 80 loaded trucks every day!)

Thankfully a large volume of the biosolids produced is dewatered by spinning it through a centrifuge, so that for

approximately every 12 trucks we used to need, we now only need 1 truck!

SOIL AMENDMENT

Soil amendment involves applying biosolids to land to add nutrients and can be used on agricultural lands or on non-agricultural lands.

DISPOSAL

The remainder of biosolids produced in the Region’s treatment plants is disposed of in approved landfills outside the Region of Waterloo.

How are Biosolids Trucked in the Region Today? Trucking is an important part of biosolids management in the Region today. There are two types of trips, both infrequent: trips between wastewater treatment plants for further processing of biosolids, and trips out of the Region for end use or disposal of processed biosolids.
