The City of Pleasanton delivered 5,632,000,000 gallons of water to approximately 73,000 customers within the City of Pleasanton during 2013. It was necessary that the City throw away 2,700,000 gallons or 0.05% of that total amount supplied to Pleasanton customers.

The city threw away that 2.7 million gallons by flushing it into the arroyos and canals in order to meet regulatory standards for health and safety. The flushing the City must do from its different storage sites is necessary because of the high counts of nitrification in the drinking water. It is anticipated that that flushed drinking water will make its way back into the Cities ground water.

The water Pleasanton purchases from Zone 7 is not of very good quality. Although Zone 7 treats the water prior to releasing it to Pleasanton, it remains salty. The ground water Pleasanton pumps and blends with the Zone 7 water is a very hard water.

From January 01, 2014 through April 2014 Pleasanton has flushed its storage
systems 25 times, because of the ongoing nitrification problem, putting 430,620 gallons Into the arroyos and canals.

I tend to believe that with the advent of water conservation in Pleasanton the water storage systems nitrification problem would tend to intensify, due to less demand which could result in higher frequencies to flush more drinking water. The City says no, that is not likely to be the case. It may just require a combination of more chlorination and/or flushing.

The number of gallons the City of Pleasanton delivered to customers should read 5,632,000. Not the 5,632,000,000 number as written above.
