Our drainfield is smaller amount than 2 years hoary and the cistern is full.? That was $8000.00 worth of work, afterwards,......NOW they want an additional $1200.00...

That was $8000.00 worth of work, afterwards,......NOW they want an additional $1200.00 to "inject chlorine" into the paddock?? Am I being ripped past its sell-by date?
Answers:    Huh? First of all, pump the reservoir! Two years on a new area makes me suspicious you any have a poorly draining corral (somebody fudged the percolation rate to get ancient the inspection) or you've really been overloading your system! With ours I could not use a dishwasher or refuse disposal...just too much more stuff going into the cistern.

Chlorine injection is most often for well, not septic system, but is related to the system. If the system is too close to the well or is not operating correctly, it will contaminate resourcefully water. Hence the okay must be cleaned. Chlorine kills microorganisms...some of which do the decomp surrounded by the septic tank. So I wouldn't be flushing down chlorine bleach into the septic container (that's another thing I'd use but discard onto the ground, not into the plumbing. ) Injecting into the soil may be an attempt to snuff out excess bacteria that flowed into the drainage lines because your holding container is being overloaded. That's lately a guess. I'd be calling other companies and ask they if they've heard of injecting chlorine and afterwards ask them why it is done. You might also contact your County Health department that regulates septic systems....tho they might feel they want to come investigate and you'd be out even more money. Hmmm. Tough call.
dump 5 to 10 gallons of bleach down the toilet it will do matching thing
