DESIGNER TRAINING SUMMARY OF TOPICS

1 Intro 1 – Intro and soils 29 Slides

Advanced Treatment System Design Course 1 – 16

This section in the first five slides summarizes the purpose and objectives, lists the instructors and sets out the Agenda for the course. The MDE intro slide is a place-holder for the local code presentation. The remainder of the slides presents a brief history of onsite wastewater treatment.

Soils as a Wastewater Treatment Medium 17 – 29

This section reviews soil structure, texture and water movement through the soil in preparation for the next section.

1 Intro 2 - Making Decisions 37 Slides

Making Design Decisions 1 - 37

This section covers making decisions from soil evaluations and explains the derivation of loading rates for boundary conditions plus estimating of hydraulic and organic loading.

1 Intro 3 - Infiltration and Contours 39 Slides

Infiltration system Design 1 – 26

This section covers concentrations and volumes of pollutants and their loading rates on the soil including some necessary wastewater math.

Slopes and Contour 27 – 39

This section discusses slope considerations for onsite design including Darcey’s Law.

1 Intro 4 - Treatment Technologies 9 Slides

These slides show different treatment technologies and how they are layed out with the soil based components. This section is expected to be expanded with detail on all treatment systems used in the region.

1 Intro 5 - Design Examples 6 Slides

The brief section discusses the decisions make for a specific soil and siting situation and the selection of the design concept. This section may be expanded to other specific soil evaluations as examples.

1 2 Hydraulics 66 Slides

The distribution systems for Mound, At grade and LPD are very similar and require the same math manipulations. This section consolidates the hydraulics design knowledge training for these systems and includes pump video and pump design and selection plus the technical needs to know for the more modern drip dispersal design.

2.1 Time Dosing - Pumping 19 Slides

This section shows how to design time dose pump stations and there different configurations as used in the selected treatment technologies.

3 Soil dispersal System Comparisons 78 slides

This section discusses the similarities and differences of the selected technologies, Mounds, At- Grade, LPD and Drip. Each technology is presented with a discussion of its unique characteristics and desired applications.

3.1 Soil Loading Rates 45 slides

This section discusses the similarities and differences of soil loading rates across the country for Mounds, At-Grade, LPD and Drip. Boundary design is presented with a discussion of rate comparisons and mass loadings.

4 Mounds 70 slides

A detailed presentation of Mound design is provided including a design example with an accompanying example plan handout.

5 At-Grade 39 Slides

A detailed presentation of At-Grade design is provided including a design example with an accompanying example plan handout.

6 Drip Dispersal 84 Slides

A detailed presentation of Drip design is provided including a design example with an accompanying example plan handout.

7 LPD 28 Slides

A detailed presentation of LPD design is provided including a design example with an accompanying example plan handout.
