Livingston, California
On September 03, 2013, City Engineer Nanda Gottiparthy gave a presentation to the City Council about the progress being made to get Well #16 back online.
(There had been several discussions about the Well and what needed to be done in order to get the Well back online. These discussions took place at Utility Rate Stakeholders Committee Meetings and at City Council Meetings.)
This is a partial Word-for-Word Transcription of what was said that evening: except for the “Um’s”, “Uh’s” and a few other Verbal Ticks.
As of the date of this posting, 10/12/2013, Draft Meeting Minutes have not yet been prepared by the City. A Video Record of the Meeting is available on the City’s website.

(And please let me know if I have made any significant errors in the transcription so I can fix them)
This Transcription begins about 8 minutes in (times are approximate) with the City Engineer stating:
As you know, the well was installed by the developer for Sunvalley Estates, designed and installed with the development and dedicated to the City. It was constructed in 2008. After the City operated the well between 2008-2010, during that time the Media was not manufactured anymore. and the City also found out that it was not a very efficient media…around 2010 they had to shut down the well because of problems with the Media performance: the breakthrough was happening.
The City’s operations crew tried their best to continue operating the well. But, the Media, because of its qualities, also because of its being very expensive, it was decided the City should start looking at other alternatives.
In 2011, City Staff, Public Works Staff, started exploring other Media and looked at several Media that were readily available in the Market. We started with about 4 or 5 Media that are widely used and a Pilot Study was conducted. Based on the results, UC Davis was contracted to perform what you call a Rapid Small Scale Test to compare the performance of all the Medial.
Of the Media that were tested, only two were selected as the top candidates for further evaluation that was done. Based on the results, the City requested proposals from the two Suppliers: providers of the media. Staff obtained data and compared the costs. These proposals from both the suppliers were presented to the Stakeholders and analysis of their costs were presented.
(12:21) During this process, these were presented in May of 2012 to the Stakeholders. The Proposals were in June and August: June, July and August when both the Media Suppliers improved on their proposals and guarantees that the City Required.
In September 2012, Staff made a recommendation for Filtronics…to be the preferred: based on their guarantee. Which was much superior compared to everyone else.
(12:45) In October of 2012, the City Council awarded a contract to Filtronics. After the award there were some time taken to evaluate the City’s other alternatives. For example: because of the cost, the City wanted to evaluate the possibility of bringing on another well into production.
Some well tests were done. Well 17 being one of them and also well 10. There were some evaluations of the costs that were performed. the City decided to proceed with the Filtronics Media change. Right now we are at the very end of installation. All of the Media change and associated work has been completed.
(Then, after explaining the Suppliers guarantee that the Media life would be 184 Million Gallons, and that how long the Media would last, in terms of time, would depend on how much water was run through it on a daily basis, (15:51) Jeff Black talked about the various pieces of equipment that were installed and why they were needed. At (19:01) Mr. black went over the list of Remaining Steps needed to return Well #16 to Service)
At (20:07) The City Engineer continued by stating:
Just wanted to (discuss) the steps that are remaining to get the well online: We’ve been discussing that with Public Works staff. Jeff Black has been assisting us. We are getting that scheduled in the next week. We also have been in touch with CDPH so that once the Calibrations process is done, they can come and take a look at the operations.
The Operations Plan: the draft has been prepared. CDPH has indicated to us that they are going to, after the field inspections, they will be able to review the Operations Plan quickly and work with the City to get the Plant on line.
At that point, the City Engineer asked if there were any questions.
