Project 92 and 93 Sewer Improvement Projects
Garden Grove Sanitary District | 2016
JIG contracted with Garden Grove Sanitary District for the preparation of construction plans and specifications for two sewer replacement projects. Both projects required upsizing of capacity deficient sewer mains.
Project 92 was located in a residential area while Project 93 was in a busy arterial street. Both projects required extensive utility research and potholing to confirm the viability of the recommended sewer alignments.
Project 92 replaced 1,478 lineal feet of 8-inch VCP sewer with 12-inch VCP sewer. For this project, a sewer segment was located inside private property, behind commercial buildings and an apartment complex. GGSD was interested in trenchless methods to replace the sewer segment or relocate the segment into the public right-of-way.
For preliminary design, JIG prepared a report which identified different construction methods to address the issue. One alternative was to pipe burst the existing 8-inch VCP sewer while inserting a new 12-inch HDPE sewer. This alternative was eliminated because of the potential damage to adjacent structures due to vibrations from the pipe bursting operations. The second alternative was to install cured-in-place pipe inside the existing 8-inch VCP. This alternative was also eliminated as it would not have increased the capacity of the existing sewer. The third alternative was to relocate the alignment on Bushard Street and tie-in to the existing 33-inch trunk sewer at the Bolsa Avenue intersection.
The proposed sewer replacement began at the intersection of Donegal Drive and Madison Circle, and continued through the residential streets to Bushard Street. From Bushard Street, the alignment proceeded south to the Bolsa Avenue intersection.
Project 93 replaced 620 lineal feet of 12-inch VCP sewer with 15-inch VCP sewer. The proposed sewer replacement started at the intersection of Anita Place and Westminster Avenue, and continued west along the north side of Westminster Avenue, up to the Euclid Street.
Traffic control plans were prepared for Project 93 on Westminster Avenue, which is a heavily traveled arterial street. The traffic control plans were processed through the cities of Garden Grove and Santa Ana.
