Bioenergy - 2021 Project Updates
See the Bioenergy project at Piscataway Water Resource Recovery Facility take shape starting in 2021.
December 2021 Update
At the bottom of the photo on the backside of the Solids Building, those long yellow metal pieces are major parts of the bridge crane rails which will be constructed inside the building.
This photo is taken inside the Solids Building. This is part of the conveyor system that will move the biosolids from the Solids Building to the Storage Facility.
A closer view of the Cake Receiving Facility with the hopper in place. Also you can see the truck approach slab, or driveway, is nearing completion.
In the center of this picture, the excavated area where the pipeline construction is underway will be where the Heat Exchanger goes. The Heat Exchanger is used in the Thermal Hydrolysis Process.
Overhead view of the Anaerobic Digesters and the Cake Receiving Facility. At the bottom of the Digesters you can see work ongoing for the overflow trench.
Some of the pipework construction getting started inside the new Digester Control Building.
Aerial view of the Combined Heat & Power project area. Concrete pads are in place for the boilers and generators. The structure at the bottom center of the photo is the new Power Distribution Center (PDC) for this area.
This is the slab being prepared for construction at the Sidestream Treatment Facility Power Distribution Center.
November 2021 Update
This is one of the existing Gravity Thickeners. It’s a big tank where the solids settle to the bottom and are removed. The Contractor has installed new mechanical equipment and a railing on the perimeter.
The new Solids Building from the backside view. The roof construction is complete and you can see the downspouts are working – but not finished yet.
This is the slab for the Electrical Building next to the Cake Receiving Area. The pipes sticking up through the steel rebar are conduits that will be housing the electrical wiring which will be connected to motor controls and other electrical equipment i
That pyramid-looking structure on the right is the receiving hopper (it’s upside down) that will be installed over that concrete box in the middle of the pit on the left. Everything will be dumped into the hopper then transferred to the silos.
This slab is for a Power Distribution Center next to the Cambi Thermal Hydrolysis Process Equipment.
The prefabricated walls have been put in place on the Digester Control Building.
All of this conduit is coming from the main Power Distribution Center vault on the Combined Heat & Power area of the project.

September 2021 Update
At the bottom left corner is the slab that will house the Gas Treatment equipment. To the right of that you can see the walls of the Electrical Vault in place. Across the road from there they are starting construction on the Digester Control Building.
The installation of the precast wall panels at the Solids Building. This is the building that houses all the dewatering equipment, including the belt filter presses.
This is a closer view of the Gas Treatment Area. The round foundation at the top of the photo will support the Gas Storage Bubble. Below that is the slab for the Gas Treatment Facility.
Aerial view looking down on the top of the Digesters. The one on the left has had the final finish coating
This is the Chemical Building for the Sidestream Treatment Process. The mechanical work is being done inside. Through the door openings on the right side you can see the chemical storage tank in place.
This is the Sidestream Treatment Tank. Sludge material goes to the Solids Building and all the liquids are squeezed out in the Belt Filter presses then it is piped to this facility to be treated.
August 2021 Progress
Aerial photo taken August 2, 2021. The Cake Storage Facility with it’s signature blue canopy is at the lower left. Our new Cambi Thermal Hydrolysis Process equipment (steel vertical tanks) which will allow us to produce Class A biosolids.
A slightly different view here. On the right, work is ongoing for the concrete slab that will support the Cake Silos. These silos will store the sludge material that is delivered from the other WRRFs and feed into the Cambi process.
This is a little bit closer view of the Storage Silo slab construction
Cambi equipment delivered and set up
The Anaerobic Digesters, the two tall, round, concrete tanks in the middle of this picture are being prepared for their final coating. To the left slabs are prepped for the Digester Control Building.
This fine example of finished concrete work is the Side Stream Treatment Tank. Here the nitrogen will be removed from the liquids that are squeezed out of the biosolids through the belt filter presses in the Solids Building.
Lower right is the Combined Heat & Power area where excavation and the slabs being poured to support the gas treatment equipment, the boilers and the generators.
This is a close-up view of the slab construction for the electrical vault at the Gas Treatment Facility.
July 2021 Progress
On the left you can see the new concrete walls on the Sidestream Treatment Building. The Digesters are in the background. Over on the right the blue canopy has been completed on the Final Cake Storage area.
The Cake Receiving pit is in the middle of this photo with the concrete walls and two dark areas above it are stone blankets being prepared for concrete slabs. There are a couple dozen piles poking up out of the ground on the slabs.
These piles will support 2 large silos that will store the sludge cake as it waits for processing. To the right of the silos is another stone area being prepared for the Cambi Thermal Hydrolysis Processing equipment.
A close up shot of the Final Cake Storage facility adorned with its new blue canopy.
The Anaerobic Digesters with their dome roofs now completed. They also have their final steel reinforcement and are waiting for their final shotcrete finish. Above the Digesters are the 4 round clarifiers. The empty one on the top right has new mechani
On the left is a better shot of the Sidestream Treatment Facility with the new walls in place. The rectangular building across the road is the Sidestream Chemical Storage Building with its new roof.
Below the Chemical Building is a better look at the new clarifier mechanical equipment.
This is the western side of the site. At the bottom of the photo is the slab for the Gas Storage Facility with the concrete walls going up on the perimeter. To the left of it is the Blower Building.
The two rectangular concrete pads on the left of this photo will support the Boilers. The excavation to the right of the pads is preparation work for the Generators.
The fresh concrete slab at the bottom right is the foundation pad for the Gas Flare Facility, which will be used to burn off excess gas that is not converted to electricity.
