Same Destination – Different Paths

With every project being considered for an Aqua Tech System, planners must consider many factors in the selection of an appropriate site specific wastewater collection system.

Such as:

Housing density and road frontage
Size of the project and wastewater volume to be conveyed
Topography and sensitive natural resources
Depth to bedrock or groundwater
Distance to the wastewater treatment and dispersal site

The Settling Tank getting a final inspection

During the design process of your system the following methods should be considered:

Conventional gravity systems (with lift stations as required)
Septic Tank Effluent Gravity (STEG) system (AKA small diameter gravity sewers)
Septic Tank Effluent Pump (STEP) pressure system
Grinder pump pressure sewer system
Vacuum

These collection or conveyance systems often represent the major portion of the total capital cost associated with any wastewater system, so careful consideration should be made to avoid extraneous expense while also ensuring reliability and environmental compliance.

Let us help you design a system that takes everything into account.

“STEP” stands for Septic Tank Effluent Pump

We put this Effluent Pump…

…into this Septic Tank (not to scale).

Technical schematics for STEP collection

Here’s how it looks when we’re done.

Our STEP system creates a pressurized, small pipe influent delivery structure to the treatment plant which eliminates the need for the expensive piping and lift stations that gravity systems require. This means that developers can cut their cost as well as defer some of that reduced cost of the community wastewater system until lots are sold. Since each home shoulders some of the load associated with wastewater treatment, the initial cost and maintenance can be distributed to the homeowners as well.

Beyond reducing development cost, STEP technology further enhances effluent water quality by leaving the majority of the solids at the point of origin where they can degrade through anaerobic processes. The effluent leaving the tank at the home then becomes the influent which the next component in the Aqua Tech system will treat through aerobic processes.
