Our Process

Once we receive a set of plans, we start designing up the effluent disposal system best suited the property based on specific information including local health department requirements, soil condition and its effectiveness to drain treated wastewater, the ground water height and the specific use of the building including and number people attending or residing in the building.
Only with all the specific information can a system be designed to comply with regulation and work effectively and efficiently.

Once we identify what type of system and disposal method is required for the property, we then make the application to the relevant local health department on behalf of our client. This will include a plan showing location of the system and contours of the of the ground.

The health department will access the application and grant approval based on our design and current regulations and standards. Once we have this approval, we then start the installation. During the installation we set up a meeting with the health department representative to inspect the installation to ensure its installed as per the approval. Providing everything is compliant the health department will issue a permit to use.

Throughout the application process we will issue the owner of the property with a maintenance contract that must be put in place to secure a permit to use form the health department. This contract will stipulate how often and when the unit should be serviced. Plumbco employs service technicians and in most cases, we return to service units biannually or annually at a fixed cost.
