The filter fits over the end of the pump discharge hose, allowing water to pass through the 100µm non-woven geotextile media while trapping sediment inside. Once 20kg of sediment has accumulated or the filter becomes difficult to pump through, it is replaced. No reuse, no cleaning, no additional equipment required.
Unfiltered excavation water carries suspended silt, clay particles, and fine aggregate in quantities sufficient to block drains, contaminate watercourses, and trigger Environment Agency enforcement action. A sediment filter bag intercepts that suspended load at the discharge end of the pump before the water reaches the drain or outfall. Water passes through the 100µm geotextile mesh. Particles above 100 micrometres are trapped inside the bag. The cleaned water exits directly to the surface water drain or watercourse. The cost of a replacement filter bag is a fraction of the cost of a vacuum tanker, a blocked drain clearance call-out, or an EA pollution incident fine.
100µm non-woven geotextile filter media: Removes suspended sediment particles above 100 micrometres from excavation discharge water. Suitable for compliant discharge to surface water drains and watercourses on low-risk sites.
Single-use design: No cleaning, no storage of dirty filter media between jobs. When the bag is full (20kg capacity) or pumping becomes difficult, remove and dispose of in standard waste and fit a replacement.
Fits 2-inch discharge hose: Ties directly over the end of a standard 2-inch pump outlet or layflat hose with the integral cord. No adaptors or additional fittings required.
450 L/min flow rate: Compatible with the flow output of a standard 110V site submersible pump at typical working head heights.
Lightweight: One-person deployment and removal. No lifting equipment required.
150 x 35cm: Compact enough to store multiples in a site van or store for ready deployment.
More cost-effective than alternatives: A vacuum tanker call-out to remove contaminated dewatering water costs significantly more than a replacement filter bag.

Groundworkers, drainage contractors, and site managers on occasional or low-volume dewatering tasks where a simple, single-use sediment filter is the correct specification. Suitable for one-off jobs, small excavations, and minor dewatering tasks where the volume of water and sediment does not justify the purchase of a reusable filter. Also appropriate for utility operatives and highway maintenance teams working on short-duration excavations where basic compliant discharge is required without complex equipment setup.
Filtering sediment-laden water from a small foundation or trench excavation before discharging to a roadside surface water drain.
Providing basic dewatering compliance on a one-off job where a single-use filter is more cost-effective than purchasing a reusable product.
Supplying one or two filters per operative for short-duration utility excavation work where each filter covers a single site visit.
Enabling compliant dewatering discharge on minor groundwork tasks where no specialist environmental equipment is otherwise required on site.
Step 1: Before fitting the filter, test the excavation water with a hydrocarbon detection strip. This filter removes sediment only. If hydrocarbons are detected, use the Green Rhino Oil and Sediment Filter instead.
Step 2: Slide the open end of the filter bag over the end of the 2-inch discharge hose. Ensure it sits fully over the hose end with a secure overlap.
Step 3: Tie the integral cord tightly around the hose to secure the bag in place. The bag must not be able to pull off under pump pressure.
Step 4: Position the filter where the discharge will exit onto a permeable surface, surface water drain, or watercourse. The filter should lie flat and allow water to exit freely through the geotextile media.
Step 5: Start the pump. Water passes through the geotextile, depositing sediment inside the bag. Monitor the filter periodically during pumping.
Step 6: When pumping becomes noticeably harder or stops, the filter is nearing full capacity. Stop the pump, remove the filter, and dispose of it with the trapped sediment in site waste. Fit a replacement before continuing.
Not testing for hydrocarbons before fitting the filter: the Economy filter has no hydrocarbon detector and does not remove oil or fuel from the water. If the water contains hydrocarbons and you discharge through this filter, the oil passes straight through to the drain. Always test with a hydrocarbon detection strip first.
Continuing to pump when the filter is clogged: if pumping becomes very difficult and the pump is working against resistance, the filter is full. Running the pump against a blocked filter risks motor overload. Replace immediately.
Using this filter for high-volume or repeated dewatering: the Economy is a single-use product rated to 20kg sediment capacity. For sites where dewatering is a regular activity, the reusable 150µm Sediment Filter is more cost-effective over multiple uses.
Not securing the cord tightly enough: a loose connection will allow the filter to be forced off the hose end under pump pressure. Tie firmly before starting the pump.
This filter removes suspended sediment only. It does not remove hydrocarbons, chemicals, heavy metals, or other contaminants. Always confirm the water contains no hydrocarbon contamination before using this filter for surface water discharge. The Water Resources Act 1991 places a legal duty on site operators to prevent polluting matter entering controlled waters. A sediment-only filter does not provide compliance cover for contaminated water. Dispose of used filters and captured sediment in accordance with site waste procedures.
This is a single-use product. This may equate to a single job or a small number of low usage jobs. No maintenance or cleaning is required. Replace when the filter reaches 20kg sediment capacity or when pumping through it becomes difficult or impossible. Store unused filters in a dry location away from direct sunlight to prevent degradation of the geotextile media.
Q: What does this filter actually do to the water?
A: The Economy Sediment Filter Bag traps suspended sediment particles above 100 micrometres in the non-woven geotextile media as water passes through it under pump pressure. The cleaned water exits through the geotextile and can be discharged to a surface water drain or watercourse. It removes suspended solids only. It does not remove oil, fuel, dissolved chemicals, or other contaminants.
Q: Does this filter remove oil or hydrocarbons from the water?
A: No. This filter has no oil retention capability and no integrated hydrocarbon detector. If the excavation water contains oil or fuel contamination, this filter will not remove it. Hydrocarbons will pass straight through the geotextile into the drain. Always test excavation water with a Green Rhino Hydrocarbon Detection Strip before fitting any sediment-only filter. If contamination is detected, use the Green Rhino Oil and Sediment Filter instead.
Q: How do I know when the filter needs replacing?
A: The filter is full when pumping becomes noticeably harder than normal or stops entirely. The geotextile pores become blocked with accumulated sediment, increasing resistance to flow until the pump can no longer push water through. At this point, stop the pump, remove and dispose of the filter, and fit a replacement before continuing. Do not force the pump to continue against a blocked filter.
Q: Why choose the Economy filter rather than the reusable Sediment Filter?
A: The Economy is the correct choice when the total volume of sediment to be removed is small, the job is a one-off, or the site does not justify the purchase of a reusable product. For regular dewatering where the same filter will be used across multiple sessions or multiple sites, the reusable Green Rhino Sediment Filter (150µm) is more cost-effective across its 20 uses. For a single low-volume job, the Economy is the practical choice.
Q: Can I reuse this filter after it fills up?
A: No. The Economy filter is designed to be replaced rather than cleaned and reused. Once 20kg of sediment has accumulated or the filter becomes difficult to pump through, remove and dispose of it in site waste and fit a new one. Attempting to empty and reuse the filter is not recommended as the geotextile media will have become compacted and its filtration performance will be compromised.
Q: What hose size does this filter fit?
A: This filter is designed for use with a 2-inch (50mm) discharge hose. It is not compatible with a 3-inch hose. If you are using the MAX 110V 750W submersible pump (PL080002) which has a 3-inch outlet, use the XL Sediment Filter which accommodates higher flow rates.
