Huitt-Zollars provided design for the replacement of approximately 12,000 linear feet of sewer, 12,000 linear feet of new sewer main, and 15,000 linear feet of new side sewers for the sewer collection system in a 250-house neighborhood. The existing system ran through backyards and under houses, and had extensive maintenance and inflow and infiltration problems. The project involved coordination of survey and geotechnical services, steep slope and challenging topography issues, public involvement including open houses and mailers, and construction of new sewer mains and existing side sewers while keeping the existing system on-line in a fully-developed neighborhood.
