Working under the direct supervision of a Registered Onsite Wastewater Practitioner (ROWP) we designed and constructed this Dosed Gravity Septic System. This system serves a one bedroom home which is located in a forested area where power outages are not uncommon.
In our planning phase we identified this site to be capable of gravity feed due to the favorable soil conditions and elevation differential t in the area that became the dispersal field.
We installed a "Flout" which is pre set to dose the dispersal field with individual 190 Liter (50 gallon) doses.  This ensures all areas of the dispersal field get used every dose rather than the traditional trickling gravity system where only a small part of the field is used.  This Flout does not require  electricity so is not affected by power outages.  A mechanical counter is installed to count all doses to the dispersal field.  This counter also requires no electricity for operation.
The laterals are connected as a circuit to ensure equal dispersal of effluent
Insulated Pressure Treated enclosures protect the Flout and Counter and also the D-box from the cold temperatures and from damage.
This is an ideal minimal maintenance septic system for any  remote, seasonal or grid tied residence. 

 


  • Distribution Box (1-2) Distribution Box (1-2) This D-box is connected to 3-4 inch laterals. An insulated Pressure Treated enclosure was built to provide protection.
  • Distribution Box (2-2) Distribution Box (2-2) This D-box is connected to 3-4 inch laterals. An insulated Pressure Treated enclosure was built to provide protection.
  • Distribution Box Video Distribution Box Video A preset amount of effluent is distributed to the laterals from the flout
  • Flout Flout This Flout is pre set to dose the disersal field with a 190 liter dose (50 gallons) each cycle. It's basic and durable design with no reliance on electricity ensure many years of trouble free operation.
  • Flout and mechanical counter Flout and mechanical counter An insulated Pressure Treated enclosure surrounds the Flout and protects the mechanical dose counter.
  • Laterals connected in circuit Laterals connected in circuit The laterals in the dispersal field are connected together ensuring equal distribution
  • Final Landscaping Final Landscaping The final grade has been graded to allow for runoff. Client can finish with grass seed or other topping.
