I'm looking for guidance documents/design information on planning, designing and constructing a vactor waste facility (i.e., a facility to dispose of waste removed from stormwater catch basins and lines).
Is there EPA or state agency guidance on this issue? I've looked but come up empty.
Is it practical to remove bacteria from stormwater runoff, given the following conditions:
The runoff is from a proposed 7-lot, rural residential development;
The site soils are primarily clay, with a very high groundwater table (i.e., no infiltration);
The runoff drains to a county ditch...
In the state of Washington, I'm looking for the law (RCW or WAC) where it's required to have a PE design and stamp utility construction within a public road and through public easements...specifically, stormwater infrastructure.
The specifics: An existing stormwater system was not performing...
I work for a local government in Puget Sound, WA. We have numerous stormwater outfall pipes that, at one time, discharged to the edge of a marine bluff (the marine bluff could be anywhere from 2 ft to 50 feet high). Over time, the bluff has eroded into Puget Sound, but the pipe now remains...
I'm looking for information on the quality of runoff from a asphalt area used to temporarily stockpile recyclable metal. We're evaluating how best to handle this water. Can we treat the water using stormwater treatment technologies ("Stormfilters", wet ponds, bioretention facilities, etc), or do...
What's the best way to get water to the bottom of a bluff w/out eroding the whole slope?
I work for a county public works department and am dealing with a stormwater outfall on a steep slope. Currently, a perforated 12" pipe carries stormwater runoff from a catch basin in a county road to the...
I'm the engineering manager for a public works agency. Our department includes four teams that report to one director. I've been asked to create and use an engineering services agreement on projects with other managers. This would be a document signed by both me and the manager we are working...
We've had reports from our stormwater O&M staff that there have been problems with the use of "Jet Set" mortar for grouting catch basin risers, pick holes, and stormwater pipes into catch basins. They have indicated the mortar is flaking off, falling off, and in general is not holding up well...
Has anyone read the book:
"The Lead Dog has the Best View-Leading your Project Team to Success" by Gordon Culp and Anne Smith.
It looks intriguing, but I'd like a recommendation before purchase.
Thanks.
I will have a stormwater pond constructed on gently sloping ground, bounded in part by a soil embankment, the other sides will be cut into existing ground. The interior and exterior slopes need to be between 3:1 and 4:1 to obtain the storage volume I need and the max slope for safety reasons...
I'm going to be interviewing candidates soon for a licensed civil engineering position with the County government I currently work for. I'm seeking some creative interview questions that help gauge a persons qualifications, experience and ability to work effectively in a team environment. The...
My County department has been asked to consider allowing the use of Raingardens as primary treament for stormwater runoff. We expect we are receiving this interest because they can be seen as a more attractive alternative than swales or wetponds (currently allowed per our Drainage manual).
Have...
I've had a professional and personal interest working on projects decommissioning roads, unused logging roads in particular and/or removal of dams- a "de-construction" of sorts. It's a small part of the civil engineering field I'd love to work in. Unfortunately, I suspect there's not a lot of...
I'm working on a grading plan of a satellite solid waste transfer station (actually a "drop box" facility). I have two luminaires to be placed within the main driving area. To protect the luminaires from traffic, I'm planning on installing barrier-type curbing. The total length of the curbing...
I'm working with four above ground, low profile truck scales (bottom of the scales 7-18 are inches above grade). Wind effects appear to be causing fluctuations on the readings up to 600 lbs, both positive and negative, with or without traffic on the scale. Fluctuations occur regardless of wind...
