sewer holding tank filling quickly

i have a holding tank (no septic field) at a cottage that is appx 1000+ gallons. I had this tank pumped out last year for the first time in 7 years. This year it started to over flow again, the cottage is only used in the summer and has never had to have been pumped out on a yearly basis. Any suggestions as to why it is filling this fast? could it be from rain water?

any help would be greatly appreciated

If the tank is not water-tight, this will allow ground water to infiltrate the system. It's bad on many levels since this same leak can cause ground water contamination.

I know they make cistern liners but I don't know if the same applies for holding tanks, check with your local septic tank guys to get the facts.

These days those plastic tanks are installed or the sectional concrete ones using high bonding adhesive between the grooved channels.

If you truly have no leach/drain field, then that tank must actually be a dry well serving in a way similar to the days-gone-by hole under the outhouse. And if so, the ground around it has probably become saturated/plugged with solids and you now need a drain field. If that system was mine, I would add a discharge pipe to that tank and drain it into an inexpensive chamber system: http://www.infiltratorsystems.com/ .
