Our nation’s aging infrastructure is a common theme in the news. We hear about deteriorating roads, high-risk dams, and old and undersized treatment plants. Wastewater infrastructure is critical to society’s daily functions, health, and safety, yet it is one of the lowest-rated aspects of our country’s framework. Improving wastewater infrastructure involves billions of dollars of repair, rehabilitation, and new construction work. A key to long-term success is to select quality and resilient construction solutions.

During this session we will investigate resilient concrete wastewater solutions. We will discuss what resilience is and why resilient construction has become a focal point in both centralized and decentralized wastewater projects across the country.

We will discuss what factors contribute to resilience and how resilient solutions can improve safety, reduce construction time, reduce costs,
and extend service life. Finally, we will investigate options for bolstering concrete’s durability while also reducing concrete’s carbon footprint.

Kayla graduated from Purdue University in 2013 with a B.S. in Civil Engineering and an emphasis in structures. Kayla is a
licensed Professional Engineer in Indiana, who joined Concrete Sealants in March 2022 as a Technical Resource Engineer.

Kayla provides technical consultation and product implementation
assistance to customers, engineers, and end-users of all ConSeal
products; she works closely with state DOTs and municipalities;
and she serves as a liaison to the specifying community.
Prior to joining Concrete Sealants, Kayla worked for the National
Precast Concrete Association for over eight years where she most
recently served as the Director of Technical Services. During her
time with NPCA, Kayla worked with various product-specific
committees, conducted Plant Evaluations at precast concrete
manufacturing plants, developed industry technical publications, and presented educational sessions at conferences and universities across the country.
Kayla’s primary areas of interest include durability and watertightness of precast concrete structures; water and wastewater storage, treatment, and conveyance infrastructure; transportation infrastructure; and
resilience.
Kayla is also involved in industry codes and standards groups including ACI and ASTM, and has served in various roles including the Secretary and Vice Chairman of ASTM Committee C27 on Precast Concrete Products, as well as the Subcommittee Chairman of ASTM C27.30 on Water and Wastewater Containers.

Earth Month 2022

Are we drowning or parched?

It seems we have been talking about a ‘water crisis’ as long as most of us have been in the water business!? THIS is the year to address how decentralized options are the solution.

During Earth Month 2022, WasteWater Education 501(c)3 will be showcasing those solutions.

A review of pilot systems designed to integrate settling techniques, and horizontal subsurface flow in constructed wetlands for the treatment of wastewater.

OSHA/CDC New Rules and COVID 19

Safe And Sound 2021

https://www.osha.gov/safeandsoundweek Safe + Sound Week is a nationwide event held each August that recognizes the successes of workplace health and safety programs and offers information and ideas on how to keep America’s workers safe.

In 2021, for the duration of this week, WasteWater Education 501(c)3 made our online/on demand CEU series free for general viewing with our thanks to Travis Vance and Patrick W. Dennison of Fisher Phillips LLP.

As a public service we are leaving the core presentation as open source/open access.

There has been growing interest in integrated iron(Fe)-salts or waterworks Fe-rich sludge uses for system-wide operation, aiming to reduce the overall chemical footprint of urban water utilities.

The multiple beneficial uses of iron (either in the form of iron-salt or iron-rich sludge) in sewer system and downstream wastewater treatment plant in an integrated manner have found to achieve sulfide removal in sewers (decreasing sewer odour and corrosion), phosphorus (P) removal during wastewater treatment, hydrogen sulfide (H2S) removal during digester biogas generation, including improving the sludge settleability and dewaterability during wastewater treatment processes.

When adopting such integrated strategy of in-sewer iron-dosing, iron is reused four times during transit through the treatment chain of urban wastewater system thereby substantially reducing chemical usages. 

The project outcomes identified clear opportunities for water and wastewater utilities to collaborate, and share the benefits, providing water/wastewater services in a cost-effective manner albeit with improved environmental sustainability.

The current presentation will primarily shed light on the underlying mechanism behind some key beneficial aspects when implementing iron-dosing in integrated sewer-wastewater treatment plant.
