We track all the new odor control projects at U.S. municipal wastewater plants. Here are some examples from our 20 page monthly updates.

Sewer Bonds Would Target Treatment Plant Odors
A proposed $150 million sewer system bond would be split between serving thousands of new homes built in Pima County each year, and fixing up aging sewer plants and lines that date back more than 80 years. Various sewer bond projects on the county's May 18 ballot would: fix odors from the 52-year-old Roger Road sewage plant; upgrade the Mount Lemmon sewer system to serve more homes; expand the Marana sewer plant's capacity by more than six times; and strengthen several sewer lines built from 1916 to 1969.

The bond would also pay for improvements to the Ina Road sewer plant, now more than a quarter-century old, to enhance its ability to meet what county officials say are increasingly stiff U.S. environmental rules governing sewer plants.

Key projects in this bond proposal include:

$20 million for the Roger Road plant, to improve odor control, improve the plant's ability to remove solids from wastewater and improve the plant's biotowers.

$17 million to build treatment facilities at the Ina Road plant to reduce nitrogen levels in its wastewater to below those allowed by state environmental standards.
$15 million for miscellaneous repairs and improvements to existing aging sewer lines.
$10 million to expand the county's Marana sewer plant to raise treatment capacity from 150,000 gallons per day to 1.15 millions gallons per day.
$7 million to upgrade the Mount Lemmon sewer system to increase capacity.

Delphos Wastewater Plant Estimate: $25 Million
After months of speculation, the city of Delphos has received an estimate of $25 million for the cost of a new wastewater treatment plant.

Following a presentation by Keith Radick of Floyd Browne Assoc. Inc., during Thursday’s special meeting, council made a motion for the engineering firm to continue with design plans for a plant utilizing membrane technology. The facility will be the largest in Ohio using membranes to treat wastewater.

According to Radick, membrane technology has been around for decades but is relatively new in wastewater plants. The exact estimate of the membrane plant is $25,055,000. Radick said the price tag is just an estimate, and noted that rising costs of building supplies such as steel could change the price.

The city is under orders from the Ohio Environmental Protection Agency to build a new plant. To stay in compliance with the Findings and Orders the city agreed to last year, final design plans must be submitted to the OEPA by June 30. The plant must be in operation by March 30, 2006. If the city fails to meet the requirements, more fines from the OEPA can be expected. Safety Service Director Greg Berquist said the case could also be given to the federal EPA and criminal charges could result.

“According to the EPA, the city must build a plant with a peak capacity of 16 million gallons a day, which includes the use of a new 4-million-gallon equalization basin. The cost of the basin is not included in the $25 million cost. The large hydraulic capacity is needed because of the city’s combined sanitary and storm sewer system. The new plant will be able to handle double the amount of water and loadings it receives from local industries than the current plant. Radick said the membrane system offers the city the most flexibility in how it is operated and the amount of wastewater that is needed to run it.

The city has an option to purchase 15 acres of land just north of Pohlman Road and east of the city dump to build the new plant. Two environmental studies have been completed at the site and the city is waiting on results of a third before buying the land. Berquist said the land appears to be satisfactory.
