Rural, Small and Tribal Grant
Building Capacity for Decentralized Wastewater Solutions in Hawaiʻi
The goal of this project is to launch Hawaii's inaugural Decentralized Wastewater Responsible Management Entity (HiRME) program by fostering partnerships across industry, academia, and government sectors, aimed at revolutionizing decentralized wastewater management and achieving the replacement of all 83,000 cesspools by 2050 through targeted training, the establishment of RMEs in key counties, and comprehensive community outreach and education to address pressing financial, operational, and technical capacity needs for decentralized systems infrastructure and long-term management.
This project, supported through the EPA’s Rural, Small, and Tribal (RST) grant program, focuses on strengthening Hawaiʻi’s capacity to manage decentralized wastewater systems through workforce training, responsible management entities (RMEs), and community education focusing particularly in rural and high cesspool density areas.
Interdisciplinary coordination will support the development of RME and organizations made up of diverse stakeholders with the technical, managerial, and financial capacity to operate and maintain decentralized wastewater systems. Through this effort, the project will launch Hawaiʻi’s first Decentralized Wastewater Responsible Management Entity (HiRME) program to ensure wastewater is managed safely and sustainably for generations to come.

The Piko Governance Model (PGM) is a collaborative structure rooted in the Hawaiian concept of piko, which signifies a central point of connection, energy, and origin (it is the naval, fontanel, or apex of a land division). The piko represents our connection to past, present and future and decisions for “ola i ka wai”, health of our shared waters are best informed from a center point that acknowledges and elevates a continuum of shared kuleana in caring for our wai.
This model ensures that decision-making is grounded in a strong, informed core and radiates outward to engage the entire community as collective stakeholders, fostering responsibility and stewardship. Information and data is transmitted multi-directionally between piko, allowing for inter-dialogue, feedback, adaptability and transparency.
The PGM framework is grounded in Hawaiʻi approaches to community planning and organization. This structure reflects the idea that knowledge, leadership, and responsibility begin at a center and radiate outward, maintaining connection to place while engaging the broader community and network. At each iteration of the piko are opportunities for multi-directional dialogue, feedback and adaptation.

The Advisory Council ensures that project activities are informed by real-world expertise and that training, technical assistance, and outreach efforts meet the needs of communities, agencies, and service providers responsible for decentralized wastewater systems. The Advisory Council provides strategic guidance to:
Inform the development of curriculum based on the Work-4-Water training model, customized for Responsible Management Entity formation
Advise the structure and instructional design of stakeholder trainings and technical assistance workshops
Identify resources, funding opportunities, and technical expertise to support RME development
Support the design of workshops that prepare leaders, agencies, and communities to manage decentralized wastewater systems
Help build statewide capacity for cesspool conversions, regionalization, and long-term system management
Provide volunteer expertise, consulting support, and technical input during project implementation
The Advisory Council works in coordination with subcommittees to ensure project activities reflect the needs of Hawaiʻi’s communities and the wastewater sector.
Subcommittee Structure - Provides focused expertise, Advisory Council members participate in one of several subcommittees based on their background and capacity.
Subcommittees include:
Financial
Operations
Ecology
Technical
Cultural / Community
Each subcommittee:
Provides subject-matter guidance
Recommends resources and training topics
Supports technical assistance activities
Identifies opportunities for collaboration
Each subcommittee will select approximately 2–3 representatives to participate in the Advisory Council. The decision-making and Communication Structure between between the Advisory Council and subcommittees will be iterative and collaborative.
Subcommittees develop recommendations, the Advisory Council reviews and provides direction
Information flows back to subcommittees for refinement
WAI will act as the convener who coordinates communication and implementation
Subcommittee assignments may evolve over time to ensure members are contributing where their expertise best supports the RST project and the formation of Responsible Management Entities.

Community engagement, involvement and trust are essential to successful wastewater solutions and this project emphasizes public education and engagement through:
Community meetings and listening sessions
Educational workshops on cesspools and decentralized wastewater systems
Clear, accessible information on replacement pathways as well as funding and management options
These efforts empower residents, property owners, and local leaders to make informed decisions and actively participate in wastewater planning. As this project progresses, community outreach and public education activities will continue to evolve, responding to community needs, feedback, and emerging opportunities for engagement. Outreach strategies, materials will be found housed on WAI’s website, and events will be refined to ensure they remain relevant, culturally responsive, and impactful.

What is the Rural, Small, and Tribal (RST) Wastewater Initiative?
The RST initiative is a program focused on improving wastewater solutions in Hawaiʻi’s rural and underserved communities. It supports workforce development, community-based management, and education around decentralized wastewater systems.
What is a decentralized wastewater system?
Decentralized systems treat wastewater at or near its source rather than sending it to a centralized sewer system. These systems are commonly used in rural areas and include technologies such as septic systems, package plants and other advanced treatment units.
What are Responsible Management Entities (RMEs)?
RMEs are organizations responsible for managing and maintaining decentralized wastewater systems within a community or region. They ensure systems are properly operated, maintained, and compliant with regulations over time.
What is the HiRME program?
The HiRME (Hawaiʻi Decentralized Wastewater Responsible Management Entity) program is a workforce training initiative designed to prepare individuals for careers in managing decentralized wastewater systems.
Who does this program serve?
This initiative focuses on supporting:
Native Hawaiian communities
Rural and underserved areas
Communities impacted by cesspools and limited wastewater infrastructure
Why is this work important?
Hawaiʻi has over 80,000 cesspools that can impact water quality and public health. Many communities lack access to centralized sewer systems, making decentralized solutions and trained professionals critical for long-term sustainability.
How can I get involved?
You can get involved by:
Partnering with the program
Participating in training opportunities
Attending community outreach events
