(visit link)

Originally constructed in 1957, and upgraded in the mid '70s and early '90s, and the most recent upgrades below completed in 2009.

The facility upgrades include:

Modifications to the existing screening, degritting, and primary settling facilities to improve performance and enhance plant automation.

New primary effluent pumping station to pump the primary effluent to a new secondary treatment process.

New 11-cell Biological Aerated Filter (BAF) facility for secondary treatment.

New primary digester operating at 55C (thermophilic) and an enclosed digester gallery to service the digester complex.

New cogeneration facility which will utilize biogas to produce electricity and heat.

New sludge dewatering facility with two new large-capacity centrifuges.

New indoor sludge storage facility operating under negative pressure and equipped with an odour treatment system.

Modifications to the existing administration building to incorporate a new control centre, boiler room and related facilities.

New 44 kV high-voltage feed to site and site wide electrical upgrades.

Various upgrades to the plant's automation and control system to improve operation interface and facilitate process optimization.

What is the capacity of the facility?: The upgraded facility will have an average treatment capacity of 95,000 m3/d Describe the biological treatment technology used.: The liquid treatment process consists of mechanical screening, aerated grit tanks with grit removal using a clamshell bucket system, chemically enhanced primary treatment through seven rectangular clarifiers, disinfection (chlorination/dechlorination), and discharge to the St. Lawrence River through a 14-port outfall located some 150 m from shore at a 20 m depth. The solids treatment process consists of anaerobic digestion operating at 37C (mesophilic), liquid hauling of biosolids from May 15 to November 15, biosolids sludge dewatering through a single centrifuge, and on-site biosolids storage for the rest of the year. Biogas (rich in methane) produced through the digestion process is currently fired in boilers to produce heat for the plant or "wasted" to a flare when the biogas production exceeds the plant's heating load. How are biosolids (sludge) managed?: Liquid hauling of biosolids from May 15 to November 15, and on-site biosolids storage for the rest of the year. What technology is used for disinfection prior to dicharge of treated water?: Chlorination/dechlorination Who is the owner/operator fo the facility?: Utilities Kingston How is the facility governed?: City of Kingston What is the website of the WWTP?: [Web Link]

Please post at least 2 original photographs of the site. We would much rather see photos of the plant itself as opposed to the front office, but we also understand that security and site layout may limit your opportunities.
