Sediment traps - a simple and effective solution to sediment in waterways

The CAREX team at University of Canterbury and Living Water have partnered to investigate how sediment traps, a simple and effective tool to capture excessive sedimentation, could be implemented across many waterways throughout New Zealand. This video describes why sediment is an issue, what a sediment trap is and how it works. It also provides guidance on how big to make a suitable sediment trap for ecological and financial benefits.

Wanderfull master ☺

Will use this concept for drip irrigation to settle water well sediment before the pressure pump. Maybe from 1 1/4" inlet before the micron sediment filter connected to 6" pvc diameter sediment "waterway" with y-tee drain back to 1 1/4" pvc to micron filter then to pressure tank. Not sure how long to make the 6" pvc, maybe 3' feet? Hopefully this keeps me from cleaning micron filter daily

Yeah, a settling tank can reduce the amount of particulate you get in your pipes/through your pump, but it can be a tricky install if it’s between the pump and the well, because it needs to hold the vacuum head created by the pump, and so it’ll probably be opaque, which leads to difficulty knowing when it’s full. My settling tank is after my pump and before my filter, so it needs to be proof of positive pressure, which lets me use translucent material and see when it needs to be unmounted and cleaned out. Dunno about your size guess, it depends on your grain size, grain density, and flow rate.

Thank you for sharing. I am looking at sediment traps for reasons of preventing sand / sediment reaching an intake pump station and being transferred to a water treatment plant. Not to mention the wear effect on the pumps themselves. Di you produce any kind of table for sediment density, diameter, velocity to determine the length of the trap needed to remove say 95% of all but the colloidal component?

[@dinornis]

Wouldn't restoring it to a wider floodplain allow sediment to be naturally trapped & reworked (lengthening the stream before it reaches outlets), preventing the need to reduce flows (and risk creating a low oxygen environment affecting invertebrate species and possibly fish passage/health) - along with reducing the risk of the river compensating by increasing bank erosion or downwards incision? That, and moving stock further away from stream banks (4:49 they might not be able to get into the stream, but the nitrogen they're leaching & microbial life certainly will - and it reduces risk of losing stock during floods by having them further away from an active floodplain)?

[@anomalyevolution40]

yeah but who wants to do that to their farmland?

[@koholohan3478]

Straight streams are bad.

[@polocrunch]

Wouldn't it be just as effective to let the stream form meanders? That would require zero maintenance and would naturally slow the water and encourage better biodiversity.

[@iwanabana]

Tractors that like straight lines no likey. Probably!

[@vivalaleta]

Good soil allows massive amounts of water to soak in. Regenerative farming is the answer.

[@Chancethecapper]

Anybody watching this because they got homework? 😭

[@Wagonrider89]

As a U.S. Citizen, I am completely ignorant of Cinnamon traps.

[@AlfioS]

@wagonrider89 A little snarky (and marginally intolerant) but hilarious all the same LOL

[@pwnz9999]

Wrong bucket on digger - it has a screening bucket on which left fine sand & silt behind while removing cobbles & pebbles - exactly wrong.

[@anthonylandrum63]

that's what I thought, maybe they should explain their reasoning. Being a year ago, doesn't look they follow up.

[@andrewparry1474]

I know nothing about it, but that was my first thought

[@dinornis]

I assume they're doing that for building the trap & misusing the footage? If not... yeah 😬

We are developing a concept on sediment as fertiliser. We r targeting small earth dam reservoirs.

[@davidstakston1950]

I always ask everyone, "What would happen to the food chain of whales if every stream was dammed and NO debris, timber, branches, leaves and seeds would ever get into the Arctic Ocean?" Yes, you would have a dead zone and no food chain for the zooplankton which is at the bottom of the whale's food chain. You are preventing the necessary nutrients from going downstream into the ocean. A quote from Senator Gaylord Nelson from Wisconsin, "Which causes society to always ask the question, if we intrude on this work of nature, what will the consequences be?"

zero chance this is effective lol
