Cesspool Improvement | Install Process

01 | Install Concrete Pad

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

02  |  Install Mata on Sewer  Before Cesspool

After the concrete is dry we can come back to complete your install. This starts by routing your sewer line through the Mata.

03  |  Install Vent

The Mata is vented to your roof line via a new vent stack.

04  |  Restart Cesspool 

We recommend a pump out and sulphuric acid treatment to restart your cesspool on the right foot from day one.

Community Developments

As Hawaiʻi grows, many developments face the same sewerage challenges:
‍
- Sewer systems facilities may be overloaded
- Excavation for septic systems will drive up costs
- Archaeological findings will delay construction
‍
Mata can be deployed like a STEP system in a low pressure sewer configuration minus the excavation.

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.
