Regulator Round Table Events
At least 25% of the US population relies on onsite systems to safely treat their wastewater.
Many of these systems serve clusters of homes through a shared 'community' system which requires additional management. The delivery of proper system management is a key issue to ensure cost-effective and long-term wastewater treatment for both new development and existing communities.
The University of Minnesota's Onsite Sewage Treatment Program and its national partners, including us, received a grant to bridge the gap between septic system professionals, regulators, and owners by developing a customizable Community System Owner's Guide (CSOG).
The CSOG will help community members and leaders understand how their system works, what management tasks need to occur on a regular basis, and how they can protect their infrastructure from premature failure.
A CSOG can be developed using a web-interface tool that will allow an individual to produce an expert-driven and locally-customized manual (electronic or hard-copy) CSOG for any cluster septic system in America.
Using this tool, an engineer, septic professional, community facilitator, or educated community member will be able to develop a guide to effective management by entering basic information on the users, system, rate structures and any regional, state, or local differences in regulations that affect the management of community systems.
This tool will enable thousands of communities across the US to properly manage their septic systems; therefore protecting our ground and surface waters.
Basic Introduction:Wastewater Treatment and Microbiology

Phosphorus and Nitrogen often need to be reduced in wastewater effluents to protect the receiving water. Ammonia is toxic to many aquatic life and phosphorus can lead to algae growth, which can cause impact aquatic life.
An interactive live introduction to the absolute basics of the history, purpose and how biological wastewater treatment systems and microorganisms operate.
This class is both for those at the very start of their careers as well as those who would just like to know more about the hidden world of microbes!
It's been since 1911 since we had a major cholera epidemic in the US. We have good health in this country because we train professionals to understand how biology and chemistry make wastewater treatment systems work. If this appeals to you, this is the basic 'how biology works' class to get you started!
Online Event: Scottish Water septic tank services.
When: Tuesday 17 March 2015, 01:45 PM - 03:30 PM

Scottish Water maintains and improves over 30,000 miles of sewer pipes which take waste water away from homes and business premises across Scotland. They then treat this at over 1,800 waste water treatment works before returning it to the environment.
Scottish Water offers a range of septic tank de-sludging services. These services are available to household and business customers who own a private septic tank which takes standard waste, such as sewage and waste water. We continually aim to deliver a high service level to all our customers. Read on to find out more about our service as well as tips on how to look after your tank and trouble shooting those problems that sometimes come up.
In 2012, Washington State Department of Health Wastewater Management Section partnered with the University of Washington's Department of Civil and Environmental Engineering to install 3 public domain, cost-effective septic treatment technologies.
A recording of this presentation is available on our YouTube For NonProfits Channel.
A US Environmental Protection Agency National Estuary Program’s (NEP) Toxics and nutrients reduction and prevention grant allocated $630,000 to evaluate the denitrification performance of these technologies. The goal of the project is to expand the list of affordable treatment options available for use in areas where nitrogen is identified as a contaminant of concern. Sewage typically contains high levels of nitrogen. Even with new technologies, on-site sewage (septic) treatment systems generally have limited ability for removing nitrogen in wastewater. This can result in increased nitrate concentrations, or "nitrogen loading" in ground and surface water. And high nitrate levels in drinking water can affect human health. Nitrogen loading is an environmental concern fueling the growth of algae. As algae dies and decays, it consumes oxygen. This process contributes to depleted dissolved oxygen conditions and can harm aquatic life.
The technologies installed have been successful in other parts of the United States in removing high amounts of nitrogen from sewage. Because denitrification processes are temperature dependent, they were chosen to evaluate their effectiveness in Washington’s climate.
The systems evaluated are:
1. A vegetated recirculating gravel filter (VGRF) that is comparable to a recirculating vertical flow constructed wetland.

2. A recirculating gravel filter followed by a vegetated denitrifying woodchip bed (RGF+WB).

3. An enhanced recirculating gravel filter (ERGF) that is also designed to maximize nitrogen removal efficiencies.

The systems were evaluated for 12 months, using the EPA/ETV Protocol for the Verification of Residential Wastewater Treatment Technologies for Nutrient Reduction (http://www.epa.gov/etv/pubs/04_vp_nutrient.pdf). Results show both the vegetated recirculating gravel filter and the recirculating gravel filter with the woodchip bed systems are reliable and effective in removing nitrogen from wastewater.
WA is developing standards and guidance for the use of these two treatment technologies. Lynn Schneider will discuss the grant process, the results and the development of standards and guidance.

Regulatory Round Table Review Series - First Event
On January 15, 2014 WasteWater Education 501(c)3 invited Environmental Health Regulatory Staff to participate in the first online hosted Regulatory Round Table Review session. (There is no charge for EH personnel)
"Understanding Microbial Induced Corrosion in precast concrete."
This in-depth 2 hour discussion is designed for those in EH Departments who inspect concrete wastewater components: those who may want more information about what to look for and those who have experience of "MICC" to share.
To Register, or confirm a prior registration, for the Regulatory Round Table Review Series please email to firstname.lastname@example.org
Recordings available here for September 11,12,13, 2012:
