It looks like the “FY2023 Ashiya City Sewerage Festa” will be held at the “Minami-Ashiyahama Sewage Treatment Plant” in Yokōchō, in the Minami-Ashiyahama area, on Sunday, September 10, from 10:00 to 16:00. ※Will be held in light rain
Quoted from the official Ashiya City website
The Sewerage Festa is an event aimed at elementary school children, held “to help residents learn about the role and structure of the sewerage system and to deepen their interest in it.” （※Preschool children can also enjoy the event together with a parent or guardian.）
There will apparently be a target-shooting game using PVC pipe water guns, tours of the sewage treatment plant, experiments and hands-on games related to sewerage, manhole cover coloring, can badge making, a stamp rally, and more!
↑On the day of the event, you can also enjoy playing in the water at “Minami-Ashiyahama Water Park,” located in front of the sewage treatment plant!

Also, at “Ashiya City General Park” across from the sewage treatment plant, food trucks are scheduled to appear, including “Miyuki Delica” serving Glover Pork and “An Com Chua” serving banh mi!（※Canceled in case of rain）
It sounds like a wonderful event where you can play in the water with your kids, learn about sewage treatment, and then enjoy tasty food from the food trucks afterward!
