E/One Named "Top Projects Award" Winner by Water & Wastes Digest

News Release:



NISKAYUNA, N.Y., Sept. 26, 2014 -- Environment One Corporation (E/One), a pioneer and world leader of low-pressure, gravity-independent, contour-following sewage collection systems, has been selected as one of the winners of Water & Wastes Digest's Top Projects Award Program. The presentation will be made on Tuesday, September 30, in New Orleans on the occasion of the Water  Environment Federation’s Annual Technical Exhibition and Conference (WEFTEC®), the largest event of its kind in North America.

In attempting to clear up an E. coli problem in the area’s lakes by replacing deteriorating septic systems, E/One and its client, the Twin Lakes Regional Sewer District in Monticello, IN, constructed the single largest grinder pump driven low-pressure sewer project in the Western Hemisphere.

"For this area, for this district, the best thing was low-pressure sewer," says Mike Darter, general manager of the Twin Lakes Regional Sewer District.  "By far and away LPS was the only way to sewer this area. It provided a timely installation with minimal disturbance to the property owners."

At present, the $65 million project counts 5,071 E/One grinder pumps which service approximately 8,000 residences and businesses around Lake Shaffer and Lake Freeman. Nearly 300 miles of pressure sewer lines link across more than 29 square miles and traverse the Tippecanoe River multiple times. The expected flow from the entire system is 1,285,000 gallons per day delivered to four separate wastewater treatment plants.

"It's quite an honor for E/One Sewer® systems, and for the grinder pump category which we pioneered and which was not too long ago considered an 'alternate' technology. Today LPS has become the 'appropriate' technology solution for a growing number of progressive communities worldwide," says E/One President Eric LaCoppola.

E/One conceived the concept of the household grinder pump in the late 1960’s. E/One Sewer systems have since proven to be an economical and effective method of sewering otherwise difficult land areas, such as flat, wet, rocky and hilly terrain.

At the heart of an E/One Sewer is the grinder pump, developed by Environment One. These units accept household sanitary waste, grind it into a fine slurry, and pressurize it to permit transport through small-diameter pipes. E/One Sewer systems now serve over one million
end-users daily.

Other participants in the Twin Lakes project include E/One’s local distributor Covalen; Gorman-Rupp; Reynolds, Inc. (now Layne Heavy Civil), Orleans, IN; HRP Construction, South Bend, IN; Rothenberger Construction, Concord, MI; Clyde E. Williams & Associates, LaGrange, IN; RheinBach Engineers, South Bend, IN; and, GRW Engineers, Indianapolis, IN.

New Video: Infiltration & Inflow Solutions

We have just released a new video, available on our YouTube channel:

https://www.youtube.com/user/eoneninja

This video explores the real cost of aging and failing gravity sewers -- not only the repairs that will be required, but the added cost of treatment. E/One low pressure sewer systems can virtually eliminate I & I, saving tens of thousands for communities.

FAQ: What's Wrong with Flushable Wipes?

Homeowners ask us about personal, flushable wipes. "If they're flushable, what's the problem?" The problem is, while they flush fine, they don't break down in water the way regular toilet paper does. and that can cause big problems.

Consumer Reports magazine conducted its own test of flushable wipes to see how they compare to regular toilet paper. Their recommendation? Toss, don't flush.

Search "flushable wipes clog" and you'll find tales from homeowners who have experienced sewage backups in their homes ... sometimes in graphic detail (consider yourself warned!). These homeowners don't even say whether or not they have grinder pumps -- the house plumbing clogged up, causing backups inside the home.

Problems have not been limited to homeowners. Municipal sewer workers around the country have had to spend a lot of time and money clearing clogs from lift stations and at the wastewater treatment plant that they say have been caused by wipes. Some municipalities have even made flushing them illegal!

Still not convinced? We came across an article in Contractor magazine that was written by a plumber. He's seen the problem first-hand.

Wastewater Infrastructure in Prefurbia

The January issue of Pumps & Systems magazine features "Wastewater Infrastructure in Prefurbia."

Rick Harrison, the author of Prefurbia: Reinventing the Suburbs from Disdainable to Sustainable, and his team have spent 30 years designing more than 700 innovative neighborhoods in 46 states and 14 countries. More communities across the U.S. are becoming aware of Rick Harrison's vision and expertise and are actively taking part in planning committees and discussions about Prefurbia. Prefurbia incorporates Harrison's green neighborhood design thoughts, innovative ideas, techniques and methods.

Learn how E/One Sewer systems can be part of the solution.

Case Study: Elwood, Kansas

The April issue of WaterWorld magazine features an E/One case study. Elwood, Kansas, has one of the largest gravity sewer system replacement projects in the country. The gravity sewer system had a lot of infiltration problems. Nine lift stations ran constantly to clear the groundwater. Manholes and sections of sewer mains were constantly sinking. Then, there was the flood of 1993.


How big of a flood? The town was washed out and need to be re-sewered. Click here to read the entire article in WaterWorld magazine.

Sewer System Technology: Vacuum Sewer vs Pressure Sewer

At first thought, a vacuum sewer system sounds like an easy, convenient alternative to a gravity sewer system. Vacuum sewers require shallow trenches, small mains, and can be used in flat or rocky areas. No individual pump stations are required at each home. But they aren’t ideal for every situation or every location, and require regular maintenance.

How a Vacuum Sewer System Works
Vacuum systems use differential air pressure to move wastewater. The system consists of one or more vacuum stations, collection system piping, valve vaults and vacuum interface valves. The sewage is transported in small diameter pipes placed at variable grade and deflection underground. The wastewater is drawn to the station and pumped to a wastewater treatment plant. Vacuum interface valves regulate the entry of wastewater and air from the valve vault into the collection system piping.

Vacuum System Disadvantages
There are a number of disadvantages to vacuum systems. First, while the mains are small and require shallow burial (just below the frost line), they are limited to approximately 20 feet of head. The sewer lines must have a specific profile of pockets or running traps, so installation requires the same attention to grade as a gravity sewer main.

The biggest disadvantage is system size. The central vacuum stations require a large capital investment, so a system for less than 50 homes is not economically feasible.

Pressure Sewer Systems
Pressure sewer systems use pump installed at each home to grind wastewater and move it to the sewer system. Pressure sewer mains are also small-diameter pipes that are buried just below the frost line, but follow the contour of the land – therefore, they don’t require the pockets or running traps that vacuum systems need. Head is limited by the capabilities of the grinder pump installed at the home (185 ft for E/One pumps), allowing for uphill pumping.

Small systems are also economically feasible. A few homes – or even one home – can connect to the sewer system at a reasonable cost. E/One’s grinder pump does not require preventive maintenance and boasts an average mean time between service calls of 8 to 10 years.
