Selecting right pump for the job
(OP)
I would like to install a submersible pump in my storm sewer pond (used to be a detention pond) so that I can outlet water to a county ditch. I have spoken with the county engineer and have been given the okay as long as I do not exceed a discharge rate of 0.2 cfs or 90 gpm. I would like to install an industrial model pump rather than a cheap one used in residential basements. I am currently looking at a HOMA TP28 (TP28V16/2/1) submersible pump but I am afraid that the discharge rate will be to high since my total head is only 5 feet. So my question is, how can incorporate an industrial pump with my pond drainage and meet the requirements of the county.

Install a valve on the pump discharge so that the pump may be throttled. Develop a method to measure the flow rate. Use a timer or a flow meter.
The HOMA brochure shows how the pump should be installed.

Google "submersible sump pump" and go through the results till you find what you are looking for.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

I would say this pump is ideal - get the V2 version at with a total head generated of 5 feet, you have a discharge rate of 90 USGPM - Perfect.
If for some reason you end up with more friction losses or a small blockage, the head increases rapidly whilst the flow stays quite high, e.g. for 20 feet head you're still getting 60 GPM
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
