Watershare presented at the 11th International Symposium on Water Supply Technology in Yokohama

During July 9 to 11 Watershare member Japan Water Research Center (JWRC) co-hosted the 11th International Symposium on Water Supply Technology, with Yokohama Waterworks Bureau, with Prof. Shinichiro Ohgaki of JWRC as Chairman. This tri-annual conference was organized this year in Yokohama, supported by Watershare and other organisations. This conference was organized adjacent to the Watershare annual meeting on July 12, which enabled the Watershare members present in Japan to also visit and participate in the conference and the exhibition showcasing the latest developments in smart water solutions and cutting-edge technologies for water supply.

This year the conference had a strong focus on novel information and communication technologies supporting facility renovation, public-private partnerships and disaster control measures, with the main theme ‘Water supply services and their future: reliable, sustainable, and smart’. The main research topics presented and discussed during the three day conference were water treatment, network management and utility management, with both Japanese and international keynotes and presenters. Dr. Emile Cornelissen of KWR, as guest speaker, presented his research on ‘controlling RO fouling after minimal pre-treatment’.

On 11 July a technical tour to the Kawai Purification Plant (CERAROCCA) of the Yokohama Waterworks Bureau was organized. This plant is Japan’s largest membrane filtration facility, which has been in place since 2014. This renewed plant, with a capacity of 172.800 m3/day, has introduced a ceramic membrane filtration system that utilizes the energy of water falling under gravity, solar power and small-scale hydropower systems. The plant is constructed in such a way that it meets the earthquake resistance standard. The construction, operation & maintenance of the plant was organized through a private finance initiative, which makes this a unique example for managing public facilities.
