What an improved septic tank is
A septic tank followed by an upflow anaerobic filter. The tank separates solids; the filter, packed with media where bacteria grow, keeps treating the water as it flows upward. The water then goes to the drain field or the next treatment stage.
What we do
- New system design for homes and lots without public sewer, sized for the number of people and the soil.
- Redesign of existing systems that overflow, smell or do not meet current regulations.
- Drawings and documents for the building permit.
The drain field is half the system
A poorly sized drain field is one of the most common causes of overflows. The design starts with a percolation test. Subsurface disposal of treated wastewater is regulated by Decree 42075-S-MINAE.
