Plymouth Utilities’ Wastewater Treatment Plant Recipient of Energy Incentive Grant Fri, 01 May 2015 20:58:43 +0000 20150501_112450_resized (2)

Plymouth, WI  (May 1, 2015)— On Friday May 1st Plymouth Utilities and Focus on Energy, Wisconsin’s statewide program for energy efficiency and renewable energy, presented the City of Plymouth with an incentive grant check in the amount $285,200 for upgrades made to Plymouth Utilities’ Wastewater Treatment Facility.

Upgrades to the existing digester included a new mixer that will increase methane gas production and two 65 kilowatt micro turbines. The City of Plymouth also received a $25,000 grant from WPPI Energy, a regional power company serving 51 locally owned, not-for-profit electric utilities.

By completing this project, the City of Plymouth will save more than 788,000 kilowatt-hours of electricity and 3100 therms of natural gas annually—enough energy to power 82 Wisconsin homes for a year. The wastewater treatment facility will also benefit from an estimated $84,450 in annual savings on its energy bills.

Not only do these upgrades save energy and money, but they’re also environmentally friendly. The annual environmental benefits are equivalent to offsetting 1602 barrels of oil from being burned – eliminating more than 1.3 million pounds of carbon dioxide (CO2) from being released into the atmosphere. Best of all, the gas produced and turned into electricity comes not only from residential waste but also from waste streams received from local food manufacturers.  Previously these manufacturers had been paying a fee to dispose of this waste.

“This resource is a benefit to both our community and local businesses,” said Mike Penkwitz, Waste Water Treatment Facility Superintendent at Plymouth Utilities.  “The digester provides a renewable energy source in the form of natural gas that is turned into energy and the remaining material is fertilizer that is spread on farm fields,” said Penkwitz.  “It may be called waste, but there’s very little that is wasted here.”

Public Hearing on Possible Electric Rate Increase Fri, 24 Apr 2015 20:33:56 +0000 CUSTOMERS OF PLYMOUTH UTILITIES

Plymouth Utilities has filed an application with the Public Service Commission of Wisconsin (PSC) to increase electric rates. The adjustment has been requested in order to cover inflationary increases in operational and maintenance expenses and costs associated with maintaining the reliability of the electric distribution system.  Additionally, the utility has asked the Commission to set appropriate rate levels which may include raising fixed customer charges.  The last electric rate increase was approved in 2011.

The requested increase in revenues is an overall increase above the electric utility’s present revenues of 4.95%, or $1,248,191. This request is detailed in the Plymouth Utilities electric rate application submitted to the PSCW on August 28, 2014.  After review, Commission staff proposed an increase in rates of $728,604, or 2.89%.  The actual change to individual customers will vary with electricity usage, class of service and ultimate rates authorized by the Commission.  All information regarding this application is available electronically at the PSCW’s website:  http://PSC.WI.GOV.

A telephonic hearing on the application has been scheduled for May 5, 2015, at 2:00 p.m. at the following locations:

Solids Removal at the Wastewater Treatment Plant Thu, 09 Apr 2015 14:03:25 +0000 After Screening and Grit Removal Comes Primary Treatment

After the wastewater is screened and the grit is removed, centrifugal pumps pump it to a splitter box that divides it among three primary clarifiers (each clarifier holds 176,000 gallons of wastewater).

The primary clarifiers allow time for the wastewater to be in a still environment where solids are allowed to settle to the bottom of these concrete tanks. These solids are called settleable solids and they typically fall in the 2% to 3% range or 20,000 to 30,000 mg/L.  About 15,000 gallons of these solids are pumped with positive displacement pumps into an anaerobic digester over a 24 hour period each day of the year.

The solids that remain in the water are called total suspended solids (TSS) and they flow out of the top of the clarifiers into aeration tanks. The floatable portion of these solids are skimmed off of the surface and pumped into the anaerobic digester.

The clarifiers are designed to handle a certain amount of gallons and solids and as those numbers increase the clarifier removal efficiency can decrease. Typical percent removal for TSS is 60% in dry weather conditions and 40% in wet weather conditions. As more solids enter further treatment plant processes more expense is needed to treat those solids. That is why it is important to reduce inflow and infiltration into the sanitary sewer system. It reduces the need for additional clarifiers or an expensive upgrade to the WWTP.
