Advanced Hydraulic Grit Removal Helps Resolve Plant’s Combined Sewer Challenges

The Shamokin Coal Township (Pa.) Joint Sewer Authority’s 2015 treatment plant upgrade and expansion, designed by Great Valley Consultants, centered on two primary goals: long-term control to mitigate overflows emanating from combined sewers and enhanced biological treatment capability. The project also expanded capacity from 7 mgd to 8.5 mgd average daily flows and peak flow conditions from 9 mgd to 13 mgd.

The Challenge

Sanitary District Benefits From Long-Lasting Pump Stations

When you ask Scarborough (Maine) Sanitary District Superintendent David Hughes what he likes most about his collection system pump stations, he'd tell you, “Absolutely nothing.” Hearing nothing, that is.

“When there's a problem, I end up having to deal with it,” Hughes said. “What I like best about them (is) I don't get involved with them.”

Recreating Responsibly

The Bishop Hodges Pastoral Center is a year-round West Virginia recreational facility known for hosting camps, business meetings and other social events. From week to week, or even day to day, the number of people on the property can vary significantly.

“We can go from 10 to 250 [people] in the blink of an eye…and then back to 10 on a moment’s notice,” said Jon DiStefano, maintenance supervisor for the Bishop Hodges Pastoral Center.

The Problem

Staying Above the Fray

Why do collection system professionals such as Linda Chappius strongly prefer the Smith & Loveless Wet Well Mounted Pump Station instead of submersibles? For starters, the pumps’ above-grade access eliminates confined space entry for routine maintenance.

“You don’t have to be in the wastewater and dealing with all the hazardous situations,” said Chappius, maintenance technician with the City of Perryville, Mo.

Clogging Problems From Flushables Get Expelled

Wastewater pump clogging issues caused by “flushables”—consumer products like wipes that are often marketed as safe for flushing—are well documented. But that does not mean they are going away anytime soon. 

A September 2013 Associated Press article, “Popular Bathroom Wipes Blamed for Sewer Clogs,” introduced the issue to a national audience: Pre-moistened wipes and other consumer goods often marketed as flushable are creating pump clogs and sewage backups in collection systems across the nation. 

Town Saves Money, Gains Efficiency with Pump Retrofits

America’s wastewater is conveyed daily by tens of thousands of pump stations, many of which were originally installed in the post-war boom era as our nation rapidly expanded. Many of these original stations still operate throughout the country, mostly in underground, dry-pit configurations. As such, municipalities with older pump stations are ultimately faced with the decisions of replacing them completely or finding less expensive routes through retrofitting internal equipment.

Pump Stations Cut Costs for Florida City

The burgeoning suburb of Pembroke Pines, Fla., boasts a forward-thinking motto: “Join Us and Progress with Us.” It certainly fits because the city is one of the Sunshine State’s 10 largest cities. Nestled just west of Fort Lauderdale and north of Miami, Pembroke Pines is full of sun, sand and something most residents probably never think about: wastewater pump stations—nearly 200 of them.

Yet because of the city’s utility pump station philosophy, staff doesn’t have to worry about them either.

Meat Processing Company Chooses Lift Station Design

Quality products with low-cost efficiencies reign supreme in the environmental marketplace. When a major pork producer sought cost-effective pumping solutions to improve its wastewater system, they found an above-grade lift station that delivered true savings.

FAST Process Handles Variable Flows for Private Tourist Attraction

Imagine pleasantly strolling through beautiful, serene, breathtaking botanical gardens when suddenly you stumble upon a wastewater treatment plant. The sweet aroma and sights of various types of flowers and plants are suddenly replaced by an unsightly treatment tank, blower noise and distinct odors. This is a scene that Powell Gardens, a privately owned botanical garden attraction outside of Kansas City, Mo., did not want for its thousands of annual visitors.

Well-Mounted Pump Stations Yield Major Repair & Maintenance Savings Over Submersibles

Today’s utility managers and public officials are faced with the challenge of keeping their systems going with dwindling funds. Instituting sound asset management practices provides a framework for acquiring and analyzing data in order to make improved decisions in the future for all kinds of infrastructure, including wastewater lift stations.

Progressive City Gets a Pump Station Upgrade

In the 1800s, the city of Peshtigo, Wis., distinguished itself as a busy center for manufactured wood products in the heart of a burgeoning timbering region. However, on the fateful night of Oct. 8, 1871, the largest recorded forest fire in U.S. history ravaged northeast Wisconsin, blazing its way through Peshtigo in devastating fashion.

Napa Winery Treats Wastewater in an Onsite Cave

Wine caves are growing increasingly popular in California’s wine country. This is especially true in Napa County, Calif., where there are more than 100 wineries utilizing a wine cave in its operation.

Caves are beneficial because they provide environmental benefits while preserving land to plant vineyards. There is one Napa winery in particular that is setting a new course within this trend. The Palmaz Winery is treating wastewater in a cave, and treating it fast.

Brewer Exudes Excellence in its Production Including Wastewater Treatment

When Sierra Nevada Brewing encountered these problems, it took the initiative to solve them while creating a win-win solution for all parties involved. A key component of that solution is a Smith & Loveless Addigest wastewater treatment system.

Delivering an Economical Treatment Solution

When the Town of Marana, Ariz. experienced rapid growth in 2000, quick but effective system solutions to their existing wastewater treatment lagoons were sought.

The upgraded facility required meeting three basic criteria: expand capacity in the short term to 150,000 gpd; enhance biological treatment capability in order that some (or all) effluent could be re-used; be cost-effective because long-term growth would eventually require a replacement system ten times larger (or 1.5 mgd).
