Major City Water Flush to Begin in NW quadrant, February 27 @ 8 am. Please flush lines if discoloration occurs.

Barring any unforeseen circumstances, the flushing is to begin at 8:00 a.m., February 27th in the northwest section of the city. It is anticipated this flushing will take one, possibly two days. The city has been divided into three sections and the Northwest section encompasses from Northwest Railroad Avenue to Highway 22 to Highway 51 North to South Park Circle.

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 three 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 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 three in early summer of 2019.
