I'm using an old version of InfoWorks (long story, don't want to switch in the middle of a project), and trying to figure out what values I should use for Horton infiltration.
When I Google it, I can find the theory and occasionally some values, but I can't find a table that relates Horton...
Hi everyone, I have a simple question about pressure regulator valves.
If there is an existing PRV in a vault, is there an indicator on it showing the pressure differential it's regulating?
Thanks.
Hi,
I have a simple question re. cleanouts vs manholes. For a private campus-sided sewer system, is it OK to use cleanouts at 90 deg bends? How do you decide?
I would think at most, you could use a cleanout at every second 90 deg bend, but not at two consecutive bends. This way every branch...
Hi everyone,
We're in the planning stages for a project in the middle east, mixed residential and commercial (~60% of the flow is residential). The downstream sewer flow has to be pumped across a bridge.
My guess is that you would size the pump for the max day flow (approx 2 x average flow)...
Hey everyone,
I'm trying to determine the rule of thumb for sewer pipe sizing. I know that for water pipes, sizing is usually based on Max Day Demand (gal/day converted to gpm), which is double Average Day Demand (the average day over the year).
Are sewer pipes also sized for Max Day flow, or...
Hey everyone,
Are there any international standards for minimum parking stall dimensions?
Metric is preferred, but in lieu of international standards, American standards would still be helpful.
Thanks,

Hey everyone,
Is it normal practice for the contractor to submit shop drawings for invert elevations for sewer or storm drain construction?
Or is it normally only shown on the as-builts whether the elevations are different than what's shown in the construction drawings?
Does it matter...
Hey everyone,
Is it industry standard to require the contractor to submit shop drawings for invert or top of pipe elevations on water pipe projects?
I know shop drawings for pipe material, joints, valves, and vaults are standard, but I can't remember whether it's standard to ask for pipe...
Hi,
One of my current projects is a utility in a well developed street. Back when we did the proposal, my boss didn't think we needed a soils report because our utility is in a street that is already well developed, and is the continuation of one we designed recently (which I think already had...
Hi,
Has anyone here ever written a business plan or done marketing work to bring business in to an engineering firm?
I'm considering working for a tiny structural firm that is looking to start a civil group to do civil site development. I have design and project management experience, but...
Hi,
I have my PE, and experience that varies from civil site design to land development to water distribution. I'm considering a new position in civil site design. I have project management experience in the latter two, but not in civil site design.
Any advice on where to read up or get...
