TEST BENCH FOR WATER-SAVING PRODUCTS

Year of implementation: 2014-2015

 

Development of works

The Test bench for water-saving products is based on the launching of an Open Innovation Space focused on the innovation of products linked to the efficient use of water, based on the Living Lab researching concept. This methodology is based on the performance of innovation activities led by the needs and restrictions from the communities benefitting from the results.

In the ZINNAE Test bench for water-saving products the following actors have been considered: public entities, plumbers, manufacturers, research entities and consumers.

The pilot phase of the project has consisted of the selection of a sample of dwellings for the evaluation of this product: water-saving toilets.

For continuous monitoring a clever water consumption meter has been designed. This device can store flow data and analyse consumer standards.

These data, together with surveys of the dwelling shave enabled the collection of valuable information for the participating companies (installer and manufacturer) such as:

  • Installed products assessment.
  • Information about the pattern of use of devices and water saving (and associated energy) reached with the introduction of saving devices.
  • Information about the return on equity for the homes of the saving products introduction, including an assessment of the associated costs and benefits.

 

Toilet’s test bench results

The data obtained in the Toilet’s test bench during the year 2014-15 have enabled a comparison of the performance of toilets with discharging capacities up to 10 l (the great majority of toilets in stalled nowadays) against ecological toilets with a discharging capacity of 2,6-4 litres (independent dual-flush depending on the kind of use). From this comparison it can be seen that the toilet’s replacement for the sample dwellings enables a reduction of the daily consumption per home, consumption per person and so the annual consumption.
