As a PLS from Pennsylvania with my own practice, my advice is if you enjoy surveying and don't mind a lot of independent study - go for it. I've been in this profession for 24 years and have always found it challenging and rewarding - physically, mentally, spiritually and yes, even financially...
We want to create 3 lots for the construction of single family residences. A town sewer and manhole is adjacent to the one of the lots. The other two lots will require a sewer extension about 400 feet long. Local and State ordinances require 2 fps velocity for an 8 inch pvc pipe flowing full...
Does anyone know the formula (or table) for calculating the size and number of anti-seep collars required to increase seepage length by 15% or better in a detention pond ? Also, are there anti-seep collars available for 8"ADS12 pipe ?
I am working on a design for a sump pump discharge for the basement of a church located in southeast Pennsylvania. The pump discharge is 1 1/2" PVC. I need run the pipe a total of 175 feet to a curb side gutter. The existing grade is approximately 2% . The pipe will cross under a public...

Can anyone provide me with flow specifications or rating table for an AquaNot Safeguard Pump System Model SP4000 ?
The company is now out of business and its successor has not been able to provide any information. I need these specs for sizing an infiltration basin to accomodate the outflow.
Have you tried HYDROCAD? I've been using it for about 6 months now and love it! I hav'nt used the direct entry for exfiltration feature but I know it's in there somewhere. Definitely worth checking out.
I am using a horizontally run section of 6" PVC culvert as the principle outlet for a retention pond. Can anyone provide me with mannings "n" and a "k" value (entrance head loss coefficient - pipe end mitered to match a 3-1 side slope; no headwall protection)? I would...
I am designing a storm water detention system which utilizes a horizontally run 6" PVC pipe as the primary outfall structure. Since the discharge is onto lawn, I need some type of difuser or splash guard at the outlet. Stone riprap is not desireable in this residential application. Can...
Hugh :
If the system's treating the sewage properly, the only discharge should be treated effluent, i.e. chlorinated water. The biggest concern I would have is keeping the chlorination low enough to prevent concentrations from killing vegetation in the area. My discharge parameters for Total...
Waterlogged :
I have a similar system which uses sand filtration, chlorination, and a stream discharge. I am required by my WQM Permit (Pennsylvania)to monitor the chlorine levels monthly and fecal choliform annually, so I've spent a good bit of time at the outfall pipe over the past 6 years. I...
I ran into this term while retracing an original warrant (1700's) in rural Pennsylvania. We determined that it referred to witness trees or other reference points which "pointed to" the corner. This seems like an unlikely term to be used in a 1960's subdivision though. What area of the...
I am presently shopping for storm water management software to use on small (less than 200 acres) watersheds in Pennsylvania. Would anyone care to share any experience with
