In our area most pumpers charge $250 or more. I charge $190 to $200. I don't use any help, saving on insurance and taxes. I am also a mechanic and I do all my own maintaince and work. Yes septic tanks need to be pumped. A lot depends on how you take care of it. Years ago we didn't use near as much water, (taking showers) and a lot of our clothes were made out of cotton which would deteriorate and brake down in the septic. Now days we have a lot of synthetic fabrics and they don't brake down. They float out to your drain field and the microbes cant eat them. After years of abuse your drain field turns in to muck and cannot absorb the water. I tell my customers to not flush any thing down the toilet except toilet paper unless they have eaten it first. Drain cleaners, mouth wash, anti bacterial soaps, Clorox, Lysol, certain medications and other things kill the bacteria in your tank. During the 60 and 70's developers went out in the suburbs and had land plotted into 100ft plots. No sewer lines telling home buyers that the big pipe would come later. (it never came and never will) Many or most of the tanks had no baffles. Most were buried and the home owner had no idea where the lids were. So out of sight, out of mind. I am seeing lots of the fail now. I am pumping a few of them every 30 days. I don't know what they are going to do. Health dept. says there is not enough yard to put in another system. I pumped one the other day that was 30 years old, never pumped. Leach field I am sure is plugged. I hate govt. regulations and intruding. When I first started out, you paid one fee to the county. You could install, repair and pump on one license. Now you must have three licenses, bonds, certification. So I don't do any repairs or installation any more as I don't have time and stay too busy pumping. A lot of contractors have gotten out of the installation business. Because of the liability. County mandates how you install it them if it fails you are on the hook. A small business that I service had to have a upgrade septic system. They followed the rules and had a system installed as to their specs. This system failed shortly after being put into service. I had to pump it once a week, at $360. (considered commercial) I agree with some of the rules, making people put risers on their system. If they don't know where their tank is, they wont have it pumped. Remember your septic system is a investment. When it quits working and sewage is backing up, that $30k boat or car wont seem too important at the time. A properly installed system if maintained can last many years. Take care you your system, Have it pumped as needed.
