Filter Bag for Catch Baskets – Effective Filtration for Road Drainage

Reliable Protection for Soakaways and Infiltration Systems

Effective road drainage is essential for protecting infrastructure and the environment. Our WINKLER filter bag for catch baskets was developed specifically to clean wastewater of solids right at the inlet point (gully). This prevents plastic litter, suspended solids, tyre wear and microplastics from reaching downstream soakaways, infiltration systems or treatment plants.

You'll find further solutions for municipal drainage systems in our Filtration for Transport & Logistics – road drainage & rainwater category.

A Professional Solution for Municipalities and Industry

Numerous municipalities, cities and industrial companies already rely on WINKLER's high quality. The polypropylene needle-felt filter bag delivers reliable filtration down to 100 µm, making an active contribution to environmental protection while reducing the maintenance costs of your drainage systems.

Targeted particle retention also plays a central role in our Filtration for Energy & the Environment – rainwater & microplastic filtration range.

Your Benefits at a Glance

  • High filtration performance: Reliably separates particles down to 100 µm as well as coarse debris.
  • Cost-efficiency: Extends the service life of soakaways and infiltration shafts.
  • Simple handling: Fast fitting and straightforward replacement in the catch basket.
  • High water permeability: Ensures safe drainage even during heavy rainfall (135 l/s/m²).
  • Custom sizes: Alongside standard sizes, we manufacture bespoke dimensions for special shaft systems.

Easy Cleaning and Replacement

The gully filter bag is designed to be removed and cleaned in a few simple steps. The hard-wearing PP material withstands mechanical stress and delivers consistent drainage performance over a long period.

FAQ – Filter Bag for Catch Baskets and Road Drains

Common Questions About Filter Bags for Catch Baskets and Gullies Filter bags for catch baskets are used in road drains to retain solids right at the inlet point. This effectively protects soakaways, infiltration systems and the sewer network. Here you'll find answers to common questions about using, the filtration performance of, and maintaining filter bags for road drainage.

What is a filter bag used for in a catch basket?

+
The filter bag is used in catch baskets in road drains or gullies to retain solids such as leaves, sand, plastic debris or tyre wear from rainwater. This means significantly fewer dirt particles reach the sewer network or infiltration systems.

What particles does the filter bag retain?

+
The filter bag reliably filters particles down to around 100 µm from the water. This includes sand, suspended solids, organic residue and fine plastic particles from tyre wear or road contamination. Water permeability is maintained, so safe drainage remains possible even during heavy rainfall.

How is the filter bag fitted in the catch basket?

+
The filter bag is placed directly into the catch basket and its flexible material adapts to the bucket's shape. Once fitted, the catch basket can be inserted into the road drain as usual. No additional installation work is normally required.

How often does a filter bag in a road drain need changing?

+
Replacement intervals depend on how contaminated the area is and how much rain falls. In heavily loaded areas such as industrial sites or busy roads, more frequent changes may make sense. In many applications, a check as part of regular shaft maintenance is enough.

What benefits does a filter bag offer for soakaways and infiltration systems?

+
Pre-filtration in the catch basket means far less sediment reaches soakaways or infiltration systems. This keeps infiltration performance intact for longer and reduces maintenance work. Filtration also helps reduce environmental impact from suspended solids and microplastics.
