The City of White Salmon is about to embark on an effort to find illegal connections to the municipal water system.  An analysis of the City’s water loss percentage in recent years shows an increase in the percentage of water lost from the system in the summer months, when the reverse should be true.  Mayor David Poucher says they plan to use ground penetrating radar to find the unknown and unmetered connections.  The City plans to offer a one-month amnesty program to allow people with unauthorized connection to come forward and have the issue corrected without penalties.  Poucher says it costs the City one dollar per thousand gallons to produce water.  He added an expected crunch on summer water supplies have added some urgency to eliminating the unmetered connections.
