HG plans treatment plant work

The village of Howards Grove has requested approval from the Department of Natural Resources for improvements to its wastewater treatment plant.

The existing treatment plant was constructed in 1965 and expanded in the early 1980s. Although the plant is in generally good condition, some of the process equipment has reached the end of its useful life. Malfunction of the aeration blowers resulted in an effluent limit violation.

Improvements to the plant include modifications to the raw wastewater pumping facilities, replacement of influent fine screens, modifications to the activated sludge compact treatment plants including replacement of diffusers, installation of a dissolved oxygen control system, sandblasting and painting, rehabilitation of covers, replacement of aeration blowers, upgrading the alum feed system, electrical and control system improvements and plant site improvements.

The project has an estimated construction cost of $1.03 million. The community anticipates financing the project using a Wisconsin Clean Water Fund loan.

Although the proposed project is not expected to involve significant environmental impacts, the public is invited to comment. Provide comments by June 14 to Gerry Novotny, Bureau of Watershed Management, Department of Natural Resources, Box 7921, Madison 53707, (608) 267-7625.
