FIRM OVERVIEW AND BACKGROUND <br /> - Decentralized Wastewater System <br /> Pilot Demonstration Project <br /> �;>. ,r.� • UNIVERSITY OF NEW MEXICO,ENVIRONMENTAL FINANCE CENTER,ALBUQUERQUE,NEW MEXICO <br /> Client Reference: <br />_ = Dawn Nall,Project Manager <br /> Environmental Finance Center,The University of New Mexico <br /> _ 505.277.0644 / dnall@unm.edu <br /> Carollo is working closely with the Community of Puako located <br /> north of Kailua-Kona on Hawaii Island on a Decentralized Wastewater Project Highlights <br /> System Pilot Demonstration Project.There are approximately • Evaluating decentralized systems to provide <br /> 130 cesspools in the Puako community that must be upgraded or an example of how they may be applied to <br /> connected to a sewer system by 2050.The Puako-Mauna Lani coral <br /> reefs are located just offshore,and recent studies showed that the cesspool conversions. <br /> coral cover was reduced by 50 percent between 1970 and 2010.The • Developing an RFP for demonstration plant. <br /> likely cause of this reduction is wastewater generated and discharged • Providing community outreach and education <br /> from nearby cesspools.The project is an EPA grant-funded,national <br /> study and Carollo is a subconsultant to the University of New Mexico, on decentralized systems. <br /> Environmental Finance Center(UNM EFC). • Providing a range of training to help implement <br /> decentralized systems. <br /> Summary of Scope <br /> Carollo performed a planning level evaluation of a 50,000 gallons <br /> per day decentralized or satellite wastewater collection,treatment, <br /> and effluent management system for Puako's cesspool conversions. wcinity Map <br /> Wastewater collection options explored include gravity and low <br /> pressure sewer systems.The satellite plant will include membrane 1 o <br /> U <br /> bioreactors and UV disinfection to produce R-1 quality effluent. H.3Na:Effluent management options include water reuse and an alternate WAMY NEPROF!!1 AREA effluent disposal method by injection well.Carollo also providedcommunity outreach and education by presenting a summary of the . r%INIYw# ko Ndecentralized system to Puako residents and other stakeholders.
