Major City Water Flush to Begin in SW quadrant, August 14 @ 8 am. Please flush lines if discoloration occurs.

The City of Ponchatoula has at last been given the go-ahead on the thorough flushing of its water lines and Mayor Bob Zabbia would like to inform residents what to expect.

Barring any unforeseen circumstances, the flushing is to begin at 8:00 a.m., August 14th in the southwest section of the city, where some areas are known as “worst offending” with brown water. It is anticipated the first flushing may take three to four days. The city has been divided into three sections and the Southwest section encompasses from Highway 22 to Southwest Railroad Avenue to Tower Road to the Service Road.

During the process, no one should be without water but may experience low water pressure and possibly short-duration discoloration. If discoloration does occur, residents are advised to run their garden hoses. This is not a matter of simply opening a hydrant and draining pipes. As explained in the past, any time a hydrant is open or a pipe breaks, it allows water flow from any direction, stirring natural sediment, making the matter worse.

Adding to that, with the Federal government’s requiring more chemicals added, more manganese has formed causing discolored water in certain areas of the city.

Since the first reports of brown water, the city has sought help from experts in the field, applying all measures suggested. Over the past two years, the city’s entire water system has been studied and every pipe and valve and their varying sizes verified and mapped to determine which valves can be opened in an orderly fashion to bring about a unidirectional flow.

The study is named the Ponchatoula Water Distribution System Flushing Program and along with the many maps, each of the three sections of the city has its own detailed large book detailing the project and step-by-step work, custom developed for its phase. The plan is based on the proper function of each valve and because this is the first time for such a massive undertaking, only the opening of each valve will tell what to expect.

Bill Travis and Thorton Bellamy and Muso had first analyzed the water and found the manganese problem. That led to the discovery that despite regular flushing, there had never been a unidirectional flushing probably in some fifty years, adding to the normal sediment buildup. Bill Travis has attended numerous national conferences on manganese and brown water this year and says the problem is nationwide, stating that while unidirectional flushing is the “best way to do it”, there will probably always be traces of brown water.

Working with Owen-White Utility Engineers in Baton Rouge, the city has access to its expertise and computer software. This company oversees not only Baton Rouge but multiple municipalities.

Sewerage and Water Department Director, David Opdenhoff, highly certified in his field, says the flushing process will be very slow, a matter of opening a specified valve at a time until a hydrant can be opened, working from south to north. All his city workers will be on hand as well as representatives from the companies who have put the project together.

He anticipates beginning Section Two in Spring of 2019 and Section three in Fall of 2019.
