FAQs About the Secondary Treatment Upgrade Project

Where can I find project updates?

To receive project updates you can:

What level of treatment does GNPCC currently provide?

The GNPCC currently provides chemically-enhanced primary treatment which uses settling tanks and gravity to treat wastewater.

What is Secondary Treatment?

Secondary Treatment uses micro-organisms to consume suspended solids in the wastewater as their food supply. It will be used in addition to primary treatment to produce a higher quality effluent.

Why is GNPCC being upgraded to secondary treatment?

The project will provide additional capacity for planned growth and will meet a commitment in the RDN's Liquid Waste Management Plan. It will also meet provincial and federal regulations which require that all municipal wastewater treatment facilities provide secondary treatment or better. Secondary treatment will improve the quality of effluent discharged to the Strait of Georgia.

How much does the project cost and how will it be funded?

The project budget is $82 million including contingency. The project will be paid for through a combination of reserves, development cost charges, borrowing and grant funding.

What kinds of construction activity can I expect?

Construction activities will last from Spring 2017 to Fall 2019 and will include:

Blasting and Drilling: May to October 2017 and early 2018
Ground Densification: Spring 2017 to Spring 2018
Earthworks: Throughout project
Concrete Works: Throughout project
Equipment and material import and installation: Throughout project
Pile Driving: Mid-October 2018 to mid-November 2018

What are the expected hours of construction?

Typical construction activity will conform to the City of Nanaimo Noise Bylaw which states that noise due to construction shall not be caused before 7:00 am and after 9:00 pm Monday to Saturday and before 9:00 am and after 9:00 pm on Sundays and Statutory holidays.

Many concrete pours are scheduled throughout 2018. Large pours may require that work continue outside of standard construction noise bylaw hours. Additionally, critical process modifications will occur several times throughout 2018 and 2019. Such work must be done at night when flows to the plant are lowest and plant flows can be shut down for a significant length of time. Note that rain has a large impact on plant flows so shutdown schedules may change based on weather conditions.
