Design and Permit to Install (PTI) for Water Use Metering – Industrial Client – Columbus, Ohio

As part of an effort to reduce sewage fees being charged to the facility, STONE prepared the design drawings and Permit to Install (PTI) for required water and sewage flow meters. The Powder Activated Carbon regeneration conducted at the plant requires a large amount of water, but does not release the equivalent amount of fluid to the sewer (as measured at the water inflow meter). The City of Columbus gave direction that the most effective method of measuring water inflow and industrial outflow and domestic/ residential outflow would be to install meters at various points of supply and discharge to provide clarity and reduce the charges for the sewer services. STONE assisted the client by reviewing existing piping, meter locations, waterline feeds, sampling points, and flow sensors. STONE then provided a basic schematic of the inflow and outflow and existing and proposed meters and prepared the general site schematic of water and sewer piping. STONE then prepared the final Design Report with Construction Drawings and the associated City of Columbus PTI.

I just wanted to reach out to both of you & all of Stone for your outstanding effort, due diligence & professionalism on this project.

I’m certainly no ESA expert, but I was blown away by the detail contained in your report, especially given the tight timeframe that was required for delivery.

Please know that your work at Walnut Grove is very much appreciated by everyone here at POAH.

For the record, I am now a huge fan of Stone Environmental, and I hope we will continue our working relationship well into the future.
