Spray Dredging / Broadcasting

The IMS Bi-Directional Broadcaster Discharge Attachment can be used for side casting material onto a canal bank, maintaining a port channel and discharging back into the normal water current, or restoring wetland habitats. Many studies have proven the beneficial use of spray dredging, and sediment additions represent one of the most promising long term actions to restore and protect wetland areas.

IMS Versi-Dredges Using Spray Dredging Around The World

A 5012 LP Versi-Dredge uses an IMS Broadcaster discharge attachment in place of the discharge pipeline configuration to spray dredge silt and sound outside of a channel in Port of Spain, Trinidad.

An IMS 7012 HP Versi-Dredge uses the Bi-Directional Broadcaster discharge attachment to spray the dredged material on both banks of a river in Iowa. The project was funded by FEMA.

An IMS 5012 LP Versi-Dredge uses an IMS Broadcaster discharge attachment to desilt a river in the Caribbean.

An IMS 5012 LP Versi-Dredge uses a Bi-Directional Broadcaster discharge attachment to spray nutrient rich dredged material from a canal onto mangroves at a U.S. National Park canoe trail.

A city government in Florida uses an IMS Broadcaster discharge attachment to placed dredged material on shore without dealing with a pipeline.

A boat passes by the cable free self-propelled IMS 5012 LP Versi-Dredge operating at a marina in Illinois. The self-propelled feature of the Versi-Dredge allows for a safer operating environment in marinas since no cables or shore anchors are required.

An IMS 5012 HP Versi-Dredge sprays dredged material onto wetlands.

An irrigation district in the U.S. uses their IMS Bi-Directional Broadcaster to spray dredged material on both shorlines.

Bay Island Drainage District uses their IMS 5012 LP Versi-Dredge to clean out their irrigation canals and uses the IMS Bi-Directional Broadcaster to deposit material on both sides of the canal. This is Bay Island’s second IMS 5012 LP Versi-Dredge.

Versi-Dredge Capabilities

Attaching the IMS Bi-Directional Broadcaster gives you the ultimate freedom without anchor cables or pipelines. The self-propelled Versi-Dredge with the attachment can spray up to 24m (80 ft.) away. This allows for continuous uninterrupted dredging at peak production levels. The material is returned in gradual layers and settles in the grasses and vegetation onshore instead of in large piles that must be moved to a landfill.

By utilizing the IMS Bi-Directional Broadcaster Discharge Attachment on your Versi-Dredge system you will be able to use the Versi-Dredge for beneficial spray dredging of nutrients on marshes and wetlands adjacent to the waterway in the dredging area.

Spreading dredged material out on the marsh surface is one of the methods proposed for supplying mineral matter to sediment starved marshes. In addition, dredged material is being used in marshes to mitigate for the impacts of canal dredging. Plants in the sediment affected areas positively respond to increasing depths of added sediment, and plant height and cover were great with increasing sediment deposition from spray pipe dredging.

A birds eye view of Bay Island Drainage Districts IMS Model 5012 LP Versi-Dredge shows how the district uses spray dredging to quickly desilt their canal network and reducing discharge costs

Nutrient rich material sprayed from a Versi-Dredge settles on farmland and the water returns to the canal. No discharge sites or dewatering costs are associated with this methodology.

A 5012 LP Versi-Dredge sprays nutrient rich material on both sides of a drainage canal. The Broadcaster attachment is available on all Versi-Dredge models.
