Full report
Springfield has moved to strengthen its evidence base for sewer-system planning, approving a $200,000 agreement with Crawford, Murphy & Tilly (CMT) for continued rainfall and sewer-flow monitoring and collection-system modelling.
The two-year, time-and-expense agreement covers the Northeast, Town Branch and Oak Knolls areas of Springfield’s sewer network. It responds to recommendations in EPA-approved revised sanitary sewer alternatives under administrative order Docket V-W-12-AO-23, which called for monthly rain and sewer-flow monitoring and modelling.
CMT will review monitoring data weekly, address data interruptions and quality issues, maintain equipment and issue monthly flow and rainfall reports. The scope specifically requires reports for every event in which the Indian Hills sanitary sewer overflow meter is active.
The monitoring network comprises nine Teledyne ISCO flow meters, five ADS Environmental Services flow meters and three rain gauges. The city remains responsible for incidental costs and repairs needed to keep the existing monitoring sites operational.
Alongside the field programme, the agreement allows Springfield to direct a portion of the $200,000 budget to development of a master collection-system model. Potential work includes defining model boundaries, reviewing sewer, rainfall, flow, pump-station, GIS and record-drawing data; conducting surveys; identifying additional monitoring locations; and combining existing models into a single InfoWorks ICM model.
The contract also includes project management and quality assurance functions, including coordination with the city over the allocation of effort between monitoring and model development.
The council separately approved a submersible non-clog wastewater pump procurement capped at $55,672 and an amendment covering engineering design, plan preparation and construction services for sanitary sewer rehabilitation along Second, Fifth and Sixth streets. Those actions sit alongside the monitoring contract as Springfield advances work on its wastewater collection system.
