Waste Water
Permit Requirements
- A permit is required prior to the construction or major repair of a sewage system for single-family residences located on lots less than three acres in size.
- A permit is required prior to the construction or major repair of a sewage system serving a facility other than a single-family residence, regardless of lot size (examples: churches, commercial properties, more than one residence on one property deed, etc.).
- A permit is required prior to the construction or major repair of a sewer system on any lot that is adjacent to a lake regulated by a Public Utility or the United States Army Corps of Engineers.
- A permit is required regardless of lot size when, during a complaint investigation, a home is found to be in violation of RSMo 701.025 through 701.059. Under the complaint procedure, a permit would be required for either a new installation or for a major repair to the existing system.

Inspectors and Evaluators for Real Estate Transactions
Inspectors and Evaluators are licensed by the Missouri Department of Health and Senior Services and are authorized to inspect or evaluate existing onsite wastewater treatment systems for real estate transactions. These individuals are not licensed to perform regulatory functions, such as inspecting installation or repairs where an onsite system construction or a building permit is needed. The GCHD does not inspect or evaluate an existing onsite sewage disposal system for real estate transactions.
A licensed evaluator can only perform evaluations. A licensed inspector can perform both inspections and evaluations. An inspection provides a thorough assessment of the onsite system and all of its components. The evaluation is a report on the general condition of the on-site system, including any signs of current or past failure. Both the inspection and evaluation include an assessment of the private water system, if one exists.
