Engineering Notes Freely Available

From March 23, 1993 (Update #16)

A series of five free technical papers about sand filtration systems for engineers, contractors and designers exploring the feasibility of sand filters for excluding zebra mussels from water supplies are available from UW Sea Grant Coastal Engineering Specialist Philip Keillor:

* "Engineering Notes #1: Case Studies of Constructed Filter Bed Intakes" is a description of 10 such systems in the western Great Lakes that range from one to 100 years old. Included is information on operational experience and whom to contact (plant operators and design engineers) for further information, plus commentary from marine contractors and design engineers.

* "Engineering Notes #2: Infiltration Intakes for Very Large Water Supplies: Feasible?" presents a review of four 20-year-old papers that considered design feasibility as a means of protecting larval organisms from entrainment in power plant and water diversion project intakes.

* "Engineering Notes #3: Zebra Mussel (Dreissena polymorpha) Distribution: Reported Size, Depth and Temperature Variables" offers a summary of relevant data about zebra mussels intended for project design engineers.

* "Engineering Notes #4: Using Filtration and Induced Infiltration Intakes to Exclude Organisms from Water Supply Systems" consists of a literature review plus an overview of slow sand filtration and infiltration systems.

* "Engineering Notes #5: Using Filtration to Exclude Zebra Mussels: The European Experience" is currently under pre-release review by several European engineers but should be available early in 1993.

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
