OK Sanitary

OK Sanitary Services has served central Wisconsin from Marshfield since 1986, and the team has over 40 years of experience. It pumps septic tanks, mound systems and holding tanks, with 5,000 gallon capacity trucks for prompt same-day service, and it does inspections every three years that meet county rules. Filter cleaning, routine maintenance, alarm monitoring guidance and emergency response for alarms and backups are offered. Commercial work includes restaurant grease trap cleaning, lift station pumping and dairy sludge removal. The company has a licensed POWTS maintainer and a master septage operator and is fully licensed and insured. Holding tanks should be pumped when the alarm goes off or before, to prevent sewage backing up into the house. Rated 4.7 from 15 Google reviews, 14 of them five stars.
