    frequently asked questions

    Why do I need to get my septic tank pumped?

    Tanks should be pumped every 3 to 5 years depending on the number of bathrooms and people in residence. Pumping prevents sludge from building up, clogging drain pipes and flowing into the drain fields and soil.  If this happens, repairs are costly.

    Why is PRO-PUMP recommended?

    Numerous household cleaning supplies and anti-bacterial products kill off bacteria in your system. Adding live bacteria to the system helps digest and/or liquify the organic waste.

    What is included in the cost?

    The cost includes labor for pumping and disposing of the waste properly. Costs vary based on the size of the tank, accessibility and if digging is required. The City of Dubuque imposes a fee per gallon of waste dumped at the treatment facility. This fee is different for intown vs out of town, and for the city’s FOG program. For example, if the city charges 10 cents/gallon and you have a 1000-gallon tank; $100 of the cost is paid to the city. Please call for an estimate. Remember once on site, if digging is required or access is difficult additional charges may incur.

    What is a Time of Transfer Inspection?

    A Certified Time of Transfer Inspector must inspect the tank per Iowa Code 567 -Chapter 69. The tank must be inspected for proper water levels and pumped to reveal any cracks or abnormalities.  Proof of secondary treatment system may include opening the distribution box, locating vents and discharge pipes for sand filter systems, and probing of drainage fields.  This can require excavation with a small backhoe. Photos and documentation are provided to the County Health Department and the Iowa DNR.
