You don't mention anything about treatment requirements so it is not clear whether or not a treatment system is required. When you say the soil scientist is "modeling" saturated hydraulic conductivity values, do you mean you are trying to determine an application rate based on a computer model...

By all means take a look at Squirt I think you will like it. Maybe I'm ringing my own bell a little but I think you will find it very powerful and flexible. Here are a few videos to help you out:

Madcowscarnival,
I wrote a program for calculating LPP systems. I will do exactly what you are trying to accomplish. There is an automatic pump selection feature that is very helpful. You can also add pumps to the pump file.
I have been letting engineers use it for free. Take a look at...

It was a long time ago and I don't remember the details. We built an exact replica of the well on a barrel added a pump and measured the headloss. Pretty basic but instructive.
What a fun little problem. To simplify the process of explaining I would first assume no water inthe tank to remove the differential pressure on the orifices. That can be dealt with later.
1) select an orifice size at the bottom of the tank.
2) select an arbitrary pressure on this orifice.
3)...

Your question made me remember I had the same question several years ago. I had a bright engineer working with me and we decided to build a model of the filter pack/well in the office and measure the headloss as a function of pumping rate. It worked great and accurately predicted the...

Good article, I enjoyed it. As far as publishing goes...I just don't have the time because I am spread so thin. I see you write software. I was writing a program and during the field testing I encountered some screwy results and figured it was time to quantify the minor losses of the...
I work with small diameter pipe often and was not satisfied with the "one size fits all" minor loss tables. The internal design of fittings varies from one manufacturer to the next and if the system response is controlled or potentially controlled by minor losses the tables are not adequate...

I have some software I have made available for free for designing and analyzing pressurized systems. It is at www.squirtonsite.com I think you will find it helpful. If we can help with your projects we would love to. If you send me an email (I think the article has my contact info) I...

We will generally work with the owners engineer by providing design and construction services. In the article, we actually helped the owners engineer design the whole system and asssited the contractor during construction. We are pretty flexible and willing to work in a variety of...

Working in cold country poses significant challenges that have the potential to become major problems if you do not account for the effects of the cold in the design. I have been designing onsite wastewater systems in the Rocky Mountain region for years and am still surprised by the...
There should not be any difference because the discharge is at the same elevation...right? Why then does the pump manufacturer indicate the elevation of the test center where the curve was developed? Obviously I am kind of confused
I will try to clarify my question. If the performance curve for a pump was developed at sea level, will actual performance at 8000 ft above sea level match the performance curve. I tested this in my test tank and it appears that due to the lower atmospheric pressure(and the numbers seem to...
