Wright-Pierce engineers were among the presenters at the annual winter New England Water Environment Association (NEWEA) conference held in Boston.
Michael Giggey addressed the recent changes in the Massachusetts state revolving loan program which provides for zero interest loans for qualifying nutrient control projects. To qualify for the favorable loans, an applicant must demonstrate that the project is "flow neutral", that it will generate no more wastewater flow than would have occurred under current zoning and onsite disposal rules. His presentation, Tools for Ensuring That Your Wastewater Project is Growth Neutral, summarizes the options available to meet that flow neutrality requirement.
Plant Operations - Phosophorus Removal, presented by Jason Jancaitis, used the Hudson, MA WWTF upgrade project as a case study for an innovative tertiary phosphorus removal process which achieved the NPDES permit level of 0.1 mg/TP.
Wastewater engineer Doug Hankins presented Tailored Approaches to Minimize Nutrient Removal Costs, which discussed how maximizing existing infrastructure, through tailored upgrades, can minimize the economic impacts of meeting increasingly stringent discharge standards.
The Ogunquit, Maine Sewer District's second largest pump station was hydraulically limited by a 50 year old, 8-inch cast iron forcemain. The forcemain runs through the historic downtown area and under several existing structures and a bridge, effectively precluding a conventional open-cut construction. Innovative Reuse of Existing Wastewater Forcemain, presented by wastewater project manager Tim Vadney, explained how capacity was increased by directionally drilling the supplemental forcemain and sliplining the existing forcemain resulting in additional capacity and redundancy.
The EPA, Climate Change, and Public Works was the topic presented by Ray Sirois, IT Director at Wright-Pierce. This session reviewed specific action steps which the EPA is taking to respond to climate change science, and the associated regulations that pertain to water, wastewater and utility management. The presentation focused on strategies which are being advocated for public works planners and engineers to prepare for changes in regulations which are likely to be coming, and changes in climate which are already here.
