跡地 群馬東部水道企業団 板倉東浄水場 配水塔 ・管理設備
The water tower has been already cut down around middle of 2017. You can see only the sign trace mark of the building. There is a control room and its facility aside remaining, but this may be soon decommissioned.
Nothing is standing here any more.
This is from the google street view preserving the past.
