The home is set back off the property 100 ft and has a drop of about 15ft. at that point. The sewer line st the street is 8ft below grade. Is there anyway this house will not need to use a pump for sewage?

If you're going to be 7' under the sewer, then yes a pump will be required.

i believe he is saying there is a total 23 feet of drop ... 23 x 4 = 89. so at 1/4 inch per foot you will not make it. but at 1/8 inch per foot you will be fine.

As long as your house is above the street you should be fine.Remember water flows with gravity.If your sewer line has to travel up, it won`t drain.

No way to tell what he means by "15' drop at that point", but if the house is below the sewer line, under the current laws of physics, he will need a pump.

You are working backwards. The distance is 100' which requires TWENTY FIVE INCHES, (NOT 25 FEET), of fall at 1/4"/foot

the laws of physics must be different between AZ and MA. but in either case you are correct. i stand with hat in hand even though i was only off by a factor of 12...

Must be because of the Kennedys.

actually it is the fault of the 'big dig'. there are so many unfixable leaks that it is affectionately known as the worlds largest car wash.
