Wetland and Bog Filters
Wetland filters, also known as bog filters, improve water quality and cleanliness by removing toxins and excess nutrients from pond water.
Understanding Wetland Filtration
Aquascape Wetland Filter System
Aquascape incorporates our patented Snorkel® Vault and Large Centipede® Module, along with a layer of AquaBlox® Water Storage Modules to provide an effective bog filter for a variety of water features. Wetland filtration is highly effective at removing sediment (suspended solids) from ponds, improves water clarity, and reduces the need for costly and invasive dredging on larger water features. The wetland filtration system works on earth bottom and liner membrane ponds and is easily retrofitted onto existing ponds. It also reduces the physical and chemical maintenance that goes along with removing algae.

1
Snorkel® Vault
Allows pump to be dropped in for easy cleaning and has four ports for Large Centipede Module attachment (Large Snorkel Vault Extensions can be used when creating deeper basins or using the AquascapePRO 10,0000 or 12-PN pump)
2
Large Centipede® Module
Sits at the lowest point in the filter and ensures maximum water distribution. Slows water velocity and provides efficient sediment removal during cleaning
3
AquaBlox®
Provides water storage area and helps slow velocity of water
4
Rubber Coupling
Creates a water-tight seal
5
Flex PVC Piping
Directs water to Centipede Module
6
Rocks and Gravel
Provides surface area for bacteria to grow and naturalizes the wetland area
7
Aquatic Plants
Absorb excess nutrients and helps to beautify and naturalize the wetland area
Wetland/Bog Filter Applications
Boerner Botanical Garden
A large, stormwater management system captures excess run-off and guides the water through a large, constructed wetland filter.
Children’s Museum of Sonoma County
A sustainable and interactive stream is recirculated through a large wetland filtration system, showcasing the importance of native wetlands to the health of local aquatic ecosystems.
Freshwater Plaza
The Freshwater Plaza in the heart of Milwaukee features the Aquascape Rainwater Harvesting System combined with a unique wetland filter.
Phipps Conservatory
A bog filter and large rainwater collection system were installed at the Center for Sustainable Landscapes at Phipps Conservatory in Pittsburgh.
Reed Street Yards
An Aquascape wetland filter replicates a river and delta system with a waterfall course that empties into a 10,000 gallon sub-surface reservoir.
Aqualand
A 250’ x 90’ ecosystem pond with a pair of large waterfalls replicates the Illinois watershed. A bog filter is included in the water feature to aid in the health and cleanliness of the pond water.
Wetland Filtration Components
Large Snorkel® Vault and Cap
Attaches to the Centipede® Module and provides an easy way to clean a wetland filtration system
Large Centipede® Module
Sits at the bottom of the wetland filter and helps to remove sediment and improve water quality
AquaBlox® Water Storage Modules
Placed directly above the Centipede® Module; helps to remove sediment and improve water quality
Large Snorkel® Vault Extension
Can be used to extend the Large Snorkel® Vault and Cap for systems with deeper basins
Half Centipede® Module
Sits at the bottom of the wetland filter and helps to remove sediment and improve water quality
