We help the municipality cut water use in residents' homes. Lower bills for people, less pressure on local sources, and the public communication ready to go — modelled on programmes proven in Germany.
Shower regulators and tap aerators for residents. People fit them themselves in a few minutes — no plumber, no work on the pipes.
A voucher in the local bulletin; collection at the town hall, the library or through social services. No installation contractor, no asset register.
Texts for the bulletin, a press release and a calculation of what the municipality and the households actually saved. Material for adaptation and ESG reporting.
From the number of households and the type of housing we set the quantity, the mix of components and the budget.
The offer and the voucher run in the local bulletin. Residents know what they get, where and by when.
Town hall, library, social services. We recommend a limit per household and splitting it into two rounds.
Residents do it themselves, in minutes. Simple instructions are included — nothing is drilled or dismantled.
From the number handed out we calculate the water and energy saved and give the municipality the material to communicate it.
Two rounds have a practical reason: the first shows the real level of interest, and only then is the rest ordered. In Freiburg, 5,500 of the first 7,500 units went in a matter of days — the second round was then 12,500.
According to the city, an average household saves roughly 8,000 litres of hot water a 300 kWh of energy — in Freiburg that came to €100–120 a year. The shower regulator there cut the flow from 16 to 9 l/min.
Source: the City of Freiburg's official bulletin (Amtsblatt no. 835, 18 March 2023). The city assumed conservatively that 75 % of the units handed out would actually be fitted. These are German figures at German prices — we will recalculate for your municipality using local water and energy prices.
They differ in who runs the programme and what triggers it. That also determines how it is argued to residents.
Model B is interesting wherever the water utility joins in — lower household draw is in its interest too. In Czechia it can build on the initiative Zachraň modrou (rewater as operator) and on the partner project Energo-Chudoba for households at risk of energy poverty — both are Czech programmes.
The programme helps residents, meets drought-adaptation goals and gives the municipality a positive story for communication and ESG.
From the scope through the components to the communication with residents.
