The document summarizes the detailed design of a UV disinfection system for the Ashbridges Bay Treatment Plant. The key points are:
1) The UV system will allow the plant to discontinue use of chlorine and seawall gates, improving effluent quality and lake water quality.
2) The design includes a new disinfection building to house UV equipment that was selected through a competitive process.
3) Construction will take place from 2017-2023, with the UV system operating during construction of a new outfall to replace the existing one.

Subdivision Design covers different phases of the land development process. We study Florida subdivision laws, site evaluation, boundaries, topographic and control surveys, and environmental and cultural considerations. Students design lot and building arrangements, all streets, and drainage channels and detention basins.
Community Meeting - Indian Run Gravity Sewer Replacement Construction ProjectFairfax County
2019 study evaluated several alternatives for replacement
Selected alternative would:
Eliminate the exposed sewer/stream crossing
Maintain level of sewer services to the community
Provide future access ease to Fairfax County’s wastewater operator
Improve system’s reliability in the area
Reduce future risk of sanitary sewer overflows
Reduce risk to public health and the environment
Gain insight into NYS Department of Transportation sensible salting tactics, including success stories and best practices in snow and ice control.
Session from a management-based forum hosted by the Cary Institute of Ecosystem Studies about the impact of road salt on natural areas and drinking water supplies, with a focus on successful salt reduction strategies being used regionally and nationally. Speaker: Rob Fitch NYSDO
This project included rehabilitation of four sanitary sewer metering vaults. These meter vaults included Dukes Car Wash, Lower Holmes Run, Tod Street, and Scotts Run. The Dukes Car Wash and Lower Holmes Run Meters are in the City of Alexandria, the Tod Street Meter is in Falls Church in the Providence District, and the Scotts Run Meter is in the Scotts Run Nature Preserve in the Dranesville District. Work included removal of existing control panels, conduits and metering equipment, rehabilitation of the interior of the vaults with a cementitious coating and epoxy liner system, installation of new control panels and conduit, and reinstallation of flow metering devices. This project was substantially complete on August 30, 2021.

Little Hunting Creek Pump Station RehabilitationFairfax County
This project included rehabilitation of the 21 MGD Little Hunting Creek Pump Station (LHCPS). Located at 8600 Stockton Parkway, Alexandria, Virginia, this pump station is the third largest pump station in the Fairfax County System. LHCPS is constructed on a 10-acre parcel that was previously utilized as the Little Hunting Creek Sewer Treatment Plant 44B. LHCPS was constructed and placed into service in 1983. Flow from LHCPS is pumped through a 30-inch force main across Little Hunting Creek to a receiving structure approximately 4,500 feet away on Surrey Court. This project was substantially complete on June 25, 2021.
This Presentation was originally given on February 2009, by JP Kenny. This company, today, is known as Wood Group Kenny. said presentation was given at the Underwater Intervention conference, and it excels in explaining what exactly is in the works, in terms of subsea technology, and where said technology is headed.

Barangaroo South District Cooling Plant (DCP) Fact SheetDeanDallwitz
Something I'm pretty proud of. Heat load still growing as the precinct gets built out, but already hitting CoP's HVAC Engineers only dream about. This is a major contributor to the Carbon Neutral, Zero Waste and Water Positive commitments for the Barangaroo South District and a bespoke project I led with some very talented Lendlease engineers. Yes designed by Lendlease and built by Lendlease. This is the only one like it in the world!
Property Developers, after a slow start, acknowledged the concept of development lifetime costing and swiftly realized the need to review their project, its components to accommodate sustainability as a driver of the engineering systems. The presentation sheds light on most Engineering systems explored including Energy and water Efficiencies through both Passive Design and Active Designs, District Cooling , Alternative Energy like Cogeneration, Solar Harvesting and Geothermal Energy with some highlights on Transportation, Parking, Foundations and Geotechnical Investigation

Russian anarchist and anti-war movement in the third year of full-scale warAntti Rautiainen
Anarchist group ANA Regensburg hosted my online-presentation on 16th of May 2024, in which I discussed tactics of anti-war activism in Russia, and reasons why the anti-war movement has not been able to make an impact to change the course of events yet. Cases of anarchists repressed for anti-war activities are presented, as well as strategies of support for political prisoners, and modest successes in supporting their struggles.
