Hi Seán,
This is off-list. 1. My understanding is that in the Irish case, such litter shouldn't end up in the ocean. Both at the street gully and sewage treatment plant levels, screens, grit chambers and baffles should remove large objects (twigs, leaves, plastic bottles), heavier-than-water objects (grit and gravel) and lighter-than-water objects (cigarette butts), even if biological treatment doesn't take place. http://www.appropedia.org/images/9/9a/Primary_Picture.jpg Of course, in a storm situation, pumping stations and sewage treatment plant can over flow. Certainly in Dublin, there is a move to separate sewage and surface water drains, although that won't improve the specific cigarette butt issue. It might be useful to approach Irish Water, Office of Public Works and individual councils to see what ends up in each main outflow - theoretically and in practice. In rural areas, road run-off will tend to end up in ditches, but I suspect there would be relatively few cigarette butts. 2. I used one of the coves on the south side of Howth Head a few years ago and found it quite littered. It was almost all larger waste - 500ml bottles, polystyrene, etc. I suspect a lot of this was either thrown or was windblown into a waterway. 3. Just on language - "gutter" conjures up the image of something associated with a roof. Here: https://www.google.ie/search?q=gutter&rlz=1C1CHBF_enIE704IE704&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjxxtvj_vvTAhUqDcAKHYdoCH8Q_AUICigB&biw=1152&bih=758#imgrc=_ all but one image is a roof. Road drains tend to be referred to as gulleys / gullies. 4. Something popular in the USA, but not Ireland are gutter guards: https://www.familyhandyman.com/roof/gutter-repair/the-best-gutter-guards-for-your-home/view-all which keep leaves, moss, etc. out of the drainage system. I wonder if road gulleys should have finer grilles.

If you are interested, following todays update, you can now log and collect information on - individual gutters - long gutters - small kerb holes and - larger kerb holes eg https://www.instagram.com/p/BToLhAHjYI_/ <https://openlittermap.com/assets/cigbutts.jpg> https://www.instagram.com/p/BTfC9-BjQxJ/ <https://openlittermap.com/assets/cigbutts.jpg> https://openlittermap.com/assets/cigbutts.jpg via OpenLitterMap.com which will be verified and made available to download anywhere in the world Feel free to add this in and consume the data via geotagged images which is free to download by anyone Kind regards, Seán -- https://openlittermap.com @OpenLitterMap (Fb, Tw, Ig) Open Litter Map<https://openlittermap.com/> openlittermap.com Involve.
