Leveraging Predictive Analytics: A Case Study
1/6/2019
Often the first notification of a spill comes from a member of the public, hours and sometimes days after the first spill. This can intensify public health and environmental impacts and the cost of clean-up efforts. Following a sewer spill at an environmentally significant site at Midway Point in August 2017, TasWater sought a way to reduce the likelihood and impact of spill events occurring in the future.

Understanding And Coping With Struvite/Vivianite Formation In WWTPs
12/21/2018
Based on wastewater properties, various types of mineral buildup can affect wastewater treatment plant (WWTP) piping. With their impacts on plant energy efficiency and potential restriction of throughput capacity, keeping pipes free-flowing is an important aspect of WWTP operations. Here’s guidance for coping with two common problems associated with phosphorus concentrations in wastewater — struvite and vivianite.

Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline
8/13/2018
Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

Water And Wastewater Pipeline Infrastructure Opportunities
3/2/2018
There is little doubt that America’s infrastructure is aging, and in some cases, operating well beyond its originally intended lifespan. With labor costs representing up to half of the cost of pipe replacement, the key to cost-effective water and wastewater utility strategies revolves as much around labor-saving installation efficiency as it does around the physical performance of a particular material. Here is a look at historic failure rates, causes, and factors to consider when replacing existing water distribution and sewer networks.

Leveraging Federal Funds To Aid Local Sewer Improvements
2/27/2018
Inflow and infiltration (I&I) are ongoing concerns for many wastewater utilities. Even with diligent maintenance of infrastructure, there are limits to what can be controlled. One example of that is leakage in the lateral service lines connecting the sewer utility’s main to sewer customer buildings. Here is how one municipality took advantage of federal and local funding to encourage nearly 2,500 customers to upgrade deficient connections in their lateral service lines — to the tune of more than $4 million.
