  Have you considered adding trends to the gap filling routine?

     No, we did not perform that. We took into account drivers and their potential impact on water demand per sector.

  Comment from AUSTRIA

  Agriculture 1990–2018 (demand for irrigation? Demand for animal husbandry is not included): from 100 Mio to about 14.3 Mio. M³. Data 2010 depend on Agricultural Structure Survey (ASS) 2010, from there on a decline is estimated.
  In Austria only a small proportion of the agricultural area is irrigated. Water demand for irrigation mainly depends on the yearly weather conditions. 2010 (the reporting year of ASS) was a year with more than average precipitation therefore the need for irrigation water was very small. In the following years Austria faced different weather conditions including several dry periods. On the contrary to the stipulated decline of irrigation demand irrigable areas have increased in Austria. The extent of irrigated areas and the irrigation volume are not monitored on a yearly basis. Data from the ASS 2020 will hopefully provide more information and also will show the use of surface waters for irrigation.
  

  Public water supply 1990–2018 (including supply of households, industry and services): from 608 Mio m³ from GW and 4,4 SW to 611 GW in 2019. According to Wasserschatz this would be between 705 Mio. m³ in 2014 and 744 Mio. m³ in 2018 for the public water supply (excluding 27,6 Mio. m³ for private households with self supply – 126 l/day for 600.000 inhabitants). In 2016 we reported around 660 Mio. m³.

     Dear Andreas, thanks for this valuable feedback. I will check with the data and try to best accomodate the values you mentioned.
