Join Frankfurt's water-saving pledge, one habit at a time
Join Frankfurt's water-saving pledge, one habit at a time The city's "Frankfurt spart Wasser!" campaign, now running its fourth-plus warm season, asks residents to treat drinking water as the precious resource it is as heat and drought periods stretch longer. Posters, tram wraps, and postcards carry pledges like "Ich dreh ab", "Ich spar's mir", and "Ich fang dich auf": turn it off, skip it, catch it. What you can do - Shower instead of bathing: five minutes under the shower uses roughly a third of a full bath (about 50 versus 150 litres), and a water-saving showerhead or flow restrictor cuts it further - Turn off the tap while brushing your teeth or lathering up: saving hot water saves energy too - Run washing machines and dishwashers only when full, on eco programmes, and look for water-efficient models when buying new - Water the garden or balcony pots in the morning or evening, collect rainwater in a barrel, and choose drought-tolerant plants How it works The city renews the campaign each warm season with posters on Litfaßsäulen, tram and digital ads, U-Bahn messaging, and postcards stocked at neighbourhood libraries, restaurants, and cafés. It is part of Frankfurt's municipal water concept for securing long-term supply, and even children get a turn, with a button-making station at the GrünGürtel-Tier's birthday festival. Why it matters Longer heat and dry spells are lowering groundwater levels in and around Frankfurt. None of these habits cost much, but multiplied across a city they ease pressure on a resource everyone assumes will keep flowing from the tap.
Clean up a square with friends and make it feel in Frankfurt
Clean up a square with friends and make it feel in Frankfurt Frankfurt has a small public square near almost every home: a market corner in Höchst, a quiet Platz in Nordend, a bench area in Ostend, a spot in Bockenheim or Westend. Most just need people to show up. Gather a few friends, spend an hour picking up litter together, then stay a while and enjoy the place you just cleaned. That is the whole idea, and it works because you repeat it. What you can do - Pick a square near where you live. Browse Wikimedia Commons: Squares in Frankfurt am Main for names and photos, or explore a district first on Visit Frankfurt: Frankfurter Stadtviertel (Bockenheim and Westend, the Brückenviertel in Sachsenhausen, Höchst's old town, Nordend and Bornheim, or Ostend along the Main). Well-known squares like Opernplatz, Konstablerwache, or Höchster Markt work too, but any square near you is just as good a start. - Message two to six friends who live close by and agree on a time. A Saturday morning works well. - Sign up once as a Sauberkeitspatin or Sauberkeitspate on the FES page Bürgerinnen und Bürger helfen mit. You choose the square or street, FES gives you grabbers, gloves, and bags and keeps restocking them, and you get one fixed contact person for questions. You clear small litter yourself and report anything larger, like dumped furniture, by phone or email. - Or plan a one-time group clean-up through FES Bürger-Sammeltage. Pick an upcoming date, such as the Main Cleanup on 12 September 2026 or World Cleanup Day on 20 September 2026. FES supplies the equipment and collects the waste afterward. For parks, playgrounds, or the city forest, contact the Grünflächenamt first (gruenflaechenamt@stadt-frankfurt.de), as the FES page explains. - Or join the citywide Frankfurt Cleanup weekend, run together by cleanffm and FES Frankfurt. The last edition, in March 2026, brought together more than 7,000 people across around 200 pickup points. The next one is set for 12 and 13 March 2027; registration opens closer to the date. - Add a reuse table once the litter is gone, the way Klimaschutz-Initiative Riedberg does it: lay out tools, toys, and household items nobody needs anymore so a neighbour can take them home instead of them being thrown away. - Finish by staying. Bring coffee, sit on a bench, talk to whoever passes by. That last part is what turns a cleaned square into a square people actually want to be in. How it works The Sauberkeitspate programme has run since 2000 and keeps adding people: 416 patrons by 2022, 476 by 2023, plus schools and kindergartens that care for an area as a group. You decide how large your patch is and how often you show up; there is no minimum. Bürger-Sammeltage work the same way for a single day: register, pick up gloves and bags at a collection point, clean, and FES takes the waste away afterward. Frankfurt Cleanup scales that same pattern to one weekend a year, city-wide. None of this changes who owns the square. It stays public land; you are simply the person, or group of friends, who looks after a small part of it. Why it matters Showing up for the same square more than once turns strangers into people you recognise and greet. It is a low-effort way to meet neighbours, and there is no guilt attached: you are not fixing a crisis, you are just making one place a little nicer to be in. A handful of small groups doing this across Frankfurt adds up to a city where public squares get used and looked after instead of avoided.
Walk the Lincoln sponge quarter
Visit a climate-adapted neighbourhood The Lincoln-Siedlung in Darmstadt is a lived example of sponge-city thinking. Built on a former US Army base in 2016, the quarter mixes modernist apartments, decentralized rainwater storage, and planted open spaces. The centrepiece is the Quartierspark, which will soon add 19 native trees and unsealed pathways to cool the microclimate by up to 5 °C on hot days. What you can do - Walk through the neighbourhood and rest in the Quartierspark shade and seating - See how unsealed surfaces and clustering trees beat the heat without gentrification - Talk to residents about what it means to live in a quarter that listens to its people How it works Darmstadt's planning started with a neighbour survey in 2025. Residents asked for more green, shade, and gathering space. The city acted on those wishes directly in the rebuild plan. Participation was design input, not decoration. Why it matters This is how equitable cooling works: hear people, plan together, build for health and joy. The Lincoln quarter shows climate adaptation can mean shared outdoor life and neighbourhood identity, not just infrastructure.
Apply for Darmstadt green and water grants
Fund your own cooling and water projects Darmstadt offers grants (Förderprogramme) for residents and businesses to plant trees, install rainwater cisterns, set up greywater recycling, and add green roofs. The city pays for up to five high-stem fruit trees per household within city limits. Solar panel subsidies, drip irrigation, and water-storage retrofits are also supported. These tools make climate adaptation an action anyone can start. What you can do - Check which grants apply to your garden or yard (trees, cisterns, greywater systems) - Apply for city funding to cover part or all of the cost - Plant native species that tolerate drought and feed bees - Store rainfall where it lands so it feeds soil, not the sewer How it works Contact the Umweltamt or Grünflächenamt with your project idea. The city reviews and approves applications that meet climate adaptation criteria. Funding covers installation; you commit to maintenance and a 5-year tenure. Why it matters Individual properties add up. When hundreds of households unseal parking, plant trees, and hold rainwater, the neighbourhood cools faster and stormwater no longer overwhelms drains. Micro-actions become macro resilience.
Explore Ludwigshöhviertel as sponge district
Walk through another climate-smart quarter The Ludwigshöhviertel, like Lincoln, was redesigned as a sponge district: rainwater versickert into sand beds, big trees are placed to lower surface temps, roofs are green where possible. Residents can see native plants and birds return to what was sealed ground. The city's freiraumplanung (public space strategy) treats both quarters as replicable patterns, not one-off projects. What you can do - Visit the neighbourhood and notice where water is held, where shade grows, where kids can play - Compare sealed vs unsealed streets and feel the temperature difference - Ask your neighbourhood Ortsbeirat if similar patterns could apply locally How it works Both quarters use the same toolkit: entsiegelung (unsealing), water-optimized tree spacing, green roofs, and stormwater that feeds the soil rather than the sewer. The city tests ideas at scale before rolling out guidance to private owners. Why it matters Once you see and feel the difference between a sponge plaza and a heat-island car park, you can't unsee it. These neighbourhoods show the shift is possible within a single city.
Follow Darmstadt's sponge-city climate plan
Join the city's climate adaptation pathway Darmstadt adopted a Klimaanpassungsplan (climate adaptation plan) in late 2025, funded by the German federal ministry. The plan sets sponge-city principles as the core response to heat waves, floods, and droughts. Residents can join summer Klimaspaziergänge (climate walks) to see projects first-hand and voice ideas for their own streets. What you can do - Attend a Klimarundgang (climate walk) in your neighbourhood (Heimstätte series starts in August 2026) - Read the Klimaanpassungsplan to understand the city's vision - Tell the Amt für Klimaschutz und Klimaanpassung which streets most need cooling or water management How it works The city runs thematic walks that show how cooling, water, and green connect. Participants learn why certain trees were chosen, how mulch holds moisture, why curb greening works. The walks are part of how the city builds shared literacy around climate action. Why it matters A plan is only as strong as the people who understand it and hold the city to it. These walks turn climate science into lived experience and community feedback loops.
Join Darmbach e.V. for stream daylighting
Advocate for living water in the city Darmbach e.V. is a 160-member civic group founded in 2008 to uncover and restore the Darmbach stream, which has flowed underground since 1970. The group argues that visible, flowing water cools the city, supports ecology, cuts stormwater costs, and reconnects residents to hydrology. Membership costs €5/year and joins a landscape-scale advocacy effort. What you can do - Join Darmbach e.V. (€5/year) and attend planning meetings and site walks - Learn why daylit streams are cheaper and cooler than hidden pipes - Advocate to your Ortsbeirat for a Darmbach section in your ward - Support the group's dialogue with city planners about Masterplan 2030+ How it works The group documents the stream's path, teaches residents about its history and ecology, and pushes municipal decision-makers to prioritize water visibility in climate plans. Each win (unsealing a section, adding a cascade) changes how a place feels and what people expect. Why it matters Hidden water is invisible infrastructure. Daylit streams are gathering places, cooling corridors, and signs that the city listens to residents who know their watershed. This is how urban hydrology shifts from pipes to commons.
Turn organic waste into Maggot-Compost with soldier flies
Turn organic waste into Maggot-Compost with soldier flies In Tori-Bossito, southern Benin, the cooperative Agro-Eco Services turns animal waste and agro-industrial leftovers into Maggot-Compost. Black soldier fly larvae cut a process that can take months down to about 12 days, then the team blends the result with biochar from agricultural waste. Farmers get a nutrient-rich organic fertiliser that feeds soil life without chemical burn. What you can do - Buy or trial Maggot-Compost if you farm or garden in Benin or neighbouring countries (Agro-Eco Services) - Visit the production site in Tori-Bossito to see larvae, biochar, and bagging in one loop - Adapt the pattern: collect local organic waste, partner with a youth coop, and sell compost instead of burning residues - Read how the model scaled from a Master's research project into a regional supplier (discovery: Africa Eye) How it works Larvae rapidly break down organic matter. After harvest, the residue is mixed with biochar and sold as Maggot-Compost to market gardeners, development partners, and research projects. The coop reports serving over 2,500 clients across Benin and neighbouring countries. Contact them via the website to purchase or partner; do not treat this page as a booking form. Why it matters More than a third of farmland in Benin faces degradation. Closing the waste-to-fertility loop keeps nutrients local, cuts dependence on expensive chemical inputs, and gives young agronomists a builder pathway that restores soil.New initiatives this month
