Project Highlights:
- Evaluation of the hydraulic adequacy of the existing sewer system
- Alternatives study to weigh advantages and disadvantages of different design strategies
- Management and oversight during contruction phase
Project Description:
The internal sewer system
at Polynesian Cultural Center (PCC) consisted of a variety of gravity and
pressure systems that collected wastewater generated within the
complex, and then conveyed it to the municipal sewer system. Although
functional, the system required more maintenance than PCC's management
wanted. It had also deteriorated and was falling below compliance levels.
Environet was asked to redesign the system such that it lessened the
maintenance burden, brought it up to the City's wastewater standards, and
would run more efficiently.
Practical modifications and upgrades were designed. Environet managed the construction of the new system featuring a 12-inch PVC main gravity sewer line that met minimum slope requirements (according to City and County of Honolulu Design Standards). In the end, PCC was left with a reliable internal sewer collection and conveyance system, which allowed PCC's management to focus their resources on serving the volume of tourists who visit the center year-round.
