cesspool question

a customer today asked me about having her cesspool pumped. she wants to know if after it is pumped does she have to add the chemicals the cesspool companies try and sell. It comes to about $200 and she said she has read on the inernet from some company in california that they doen’t recommend using them and that they use something not so detromental to the ground. my question is if this is true do they add the california checmicals right at the same time it is pumped or not.

Another words can you just have a cesspool pumped with no chemicals after or do you have to add the chemicals when done?

Thanks guys, I just am not sure.

If you are refering to a septic system with a sediment tank or tanks and a leech field, no chemicals are necessary in a properly designed and funtioning septic system.
