New Builds

Start small. Grow Intentionally.

When you’re building from scratch, wastewater shouldn’t dictate your vision. Traditional septic systems systems assume you already know the final size of your home. Five bedrooms? Three bathrooms? Future ADU? They demand demand excavation, permits, and high upfront costs. Composting or dry systems compromise comfort and convenience.

The Mata system bridges that gap — providing a flush-ready, aboveground solution that’s easy to install, modular by design, and built for Hawai‘i’s terrain.

✓ Above-ground management first.
✓ Scalable liquid dispersal second.
✓ Eco-friendly expansions on your time.

Planning Process

Building out agroforestry? Growing bananas? Planting breadfruit? We think about how water moves through your property — not just how to get rid of it. Your wastewater becomes part of your land planning, not separate from it.

01 | Install Concrete Pad

A 3" concrete pad is installed to provide a stable foundation for your Mata.

02 | Install Mata on Household Sewer

The Mata receives your 3" wastewater pipe at a minimum height of 16" above grade.

03 | Install Vent and Gravity Backup

The Mata is vented above your roofline while a gravity flow path to your leachfield is added in the event of a power failure.

04 | Install Low Pressure Liquid Discharge

The pumped liquid outlet is connected to additional treatment or directly to WaiHome's at-grade leachfield product.

01 | Talk story with WaiHome

We walk your land, listen to your plans, and determine how WaiHome technologies can support your build today without limiting tomorrow.

03 | Solid Management

Establish sanitation first. Mata manages solids above ground, allowing you to have a flush toilet and indoor plumbing without overbuilding underground infrastructure.

02 | System Design + Deployment

Install what you need - we design for your current phase and deploy quickly with minimal excavation and minimal disruption to your land.

04 | Liquid Disposal

With solids handled, we integrate enhanced liquid treatment and dispersal strategies — including reuse opportunities — so your wastewater supports your growing property instead of limiting it.

Liquid Disposal

With the solids safely treated, liquid disposal now becomes a point of focus; liquid effluent disposal or additional treatment can be defined by what bests suits your properties needs. Modularity is our strong suit: curious about water reuse, agricultural options, or have another technology in mind? Reach out, we’d love to discuss it.

Mata Maintenance

Mata separates solids from raw sewage and then dehydrates and steralizes them for disposal. The inclusion of two solids bins allows one bin to be filling while the second is drying. Solids are removed and the bins swapped once every 4-12 weeks depending on your usage.

Mata and the Mandate

Currently, Mata is a UPC 1009 compliant solids separator, meaning it just needs an over-the-counter plumbing permit and install by a licensed plumber.

However, our work doesn’t stop with Mata. We’re also developing Patu and Sawa — excavation free liquid treatment and disposal systems that work with Mata to complete your cesspool replacement before the 2050 deadline. We are currently working with regulators to make this a fully permitted solution and are gearing up for statewide use.
