Description: Implementation of a Private Lateral Inflow and Infiltration Pilot Study
Implementation of a Private Lateral Inflow and Infiltration Pilot Study
Abstract
In 2015 and 2016 the City of St. Petersburg, Florida (City) experienced extreme wet weather resulting with unauthorized discharges due to capacity limitations in the sewer collection system, water reclamation facility (WRF) effluent filters, injection wells and impacts from inflow and infiltration (I/I). The City engaged a team of professional engineers to evaluate the wastewater collection system and WRFs to identify the most cost-effective solution to mitigate potential similar overflows during future storm events. The City advanced development of a Wet Weather Overflow Mitigation Program (WWOMP). The WWOMP Phase I Study recommended improvements to the WRFs and I/I removal from the collection system to reduce flows to the WRFs and increase capacity in the sewer network to reduce the likelihood of future overflows. Preliminary recommendations from the WWOMP included an I/I pilot program be performed to assess the effectiveness of various I/I removal approaches to determine which work best for the City. As the WWOMP was being finalized, the City initiated an I/I pilot study in the Maximo Moorings neighborhood within the Southwest WRF (SWWRF) collection system. The initial phases of the Maximo Moorings Pilot Study focused on inspection and rehabilitation of the City’s public infrastructure. Work included lining of gravity mains and the public portion of laterals, defect repair in manholes and sewers, and the installation of manhole inflow dishes. Pre-construction and post-construction flow monitoring was performed to estimate the potential I/I reduction associated with rehabilitation of the public infrastructure. Although data limitations made comprehensive analysis of the Maximo Moorings Study challenging, it was generally concluded that rehabilitation of public infrastructure alone did not achieve the desired I/I reductions. Private sources of I/I are often also significant contributors to wet weather flow. A Water Environment Research Foundation (WERF) Study reported a range of private sector I/I contributions of 7% to 80%, with a mean of 40% based on a survey of 26 utilities (WERF, 2006). The City subsequently implemented a Private Lateral I/I Pilot Study (Pilot Study) expanding inspection and rehabilitation to the private laterals in the Maximo Moorings neighborhood. Because I/I is highly dependent on the characteristics of the targeted collection system, rehabilitation programs focused on removing private sources of I/I often have wide-ranging results. This same variability in I/I from system to system and from basin to basin is expected in St. Petersburg and will be incorporated as the City plans for the future implementation of a City-Wide Private Lateral I/I Program. This paper presents a step-by-step process to successfully implement a private lateral inflow and infiltration pilot study and discusses the preliminary results of the impacts of performing private lateral rehabilitation to mitigate I/I on a coastal community's wastewater collection system.
This paper is intended to present engineers with a step-by-step process that will successfully mitigate wet weather impacts for a coastal community's wastewater collection system through private property inflow and infiltration (I/I) mitigation. The process builds upon work performed within the City of St. Petersburg, Florida (City) to date and incorporates the City’s understanding of its own infrastructure for the implementation of a pilot study focusing on the inspection and rehabilitation of private laterals to further eliminate I/I. The process implemented, lessons learned, and results of the study will guide the next steps for the implementation of a City-wide Private Lateral I/I Program.
