What Does On-line Tank Mean?
An On-line tank is defined as a huge storage tank that stores excess water from sewer overflow in times of heavy storms and floods. This overflow would otherwise empty directly into rivers or onto the streets. The tank fills up during overflow periods until the sewerage system is back to normal when it then slowly empty's back into the system. These tanks are located at a depth to allow gravity to fill them. Trenchless technology enables a cost effective approach to repairing old pipelines situated below ground and repairing or connecting an on-line tank.
