PDG was hired by Northwestern Water and Sewer District to provided professional engineering and bidding services for the design and construction of the Colony Area Inflow & Infiltration Reduction Improvements in Rossford, Ohio. This project consisted of pipe bursting of approximately 9,000 LF of 8” and 10” Vitrified Clay Sanitary Sewers with new 8” and 10” Certa-Flo Green Line PVC pipe. Sewer service laterals were also burst and replaced to the R/W. Pipe Bursting was specified for the replacement of this aging sewer system for several reasons. Due to the existing pipe being in such poor condition lining was ruled out. This system is also located within a historical neighborhood in the City of Rossford. The Colony sub-division has many mature trees, landscaped islands and a variety of architectural monuments which are locally sensitive. Pipe bursting allowed the re-construction of the sewers to be significantly less of a disturbance to the neighborhood then would have been experienced in a traditional open-cut method. It also proved to be more cost effective when evaluated against open cut-replacement. For these reasons, pipe bursting was chosen for the replacement of the sewers and has been well received by residents. This project was funded wholly through EPA’s WPCLF.

The final phase of the City of Bowling Green Master Plan Improvements was the replacement of the existing 500,000 gallon elevated tank with a new 1.5 million gallon tank located in the City’s north side industrial and commercial corridor. This area was identified as the optimal location for a new tank due to it’s proximity to the 20” and 36” transmission mains that are the main feeds from the City water treatment plant. As a supplement to the original master plan, PDG performed water age analysis and the effects of the recommended improvements to optimize the system and enable the City to maintain current and future compliance with the Ohio EPA disinfection byproducts rules and regulations. This analysis will help the City maintain a healthy water supply to their customers.
