| The Intrusion Calculator indicates valves used to isolate an intruded pipe. |
A location or area where intrusion takes place is defined by the user. The Intrusion Calculator indicates valves used to isolated an intruded pipe. These are highlighted on the system Map. Volume, number of customers and total demand are reported for both the area that experiences intrusion and the areas that are isolated from a source by the closed valves. Intrusion Area is the affected area which is contained by the closed valves. Water in the Intrusion area could potentially drain out of the compromised pipe, and may not be under pressure due to the closed valves. Isolated Areas are areas not directly affected by intrusion but which are no longer connected to a source (tank, water plant) due to the closed valves. |
