Summarize this article for a 10 year old

Decentralized wastewater systems treat, reuse or dispose the effluent in relatively close vicinity to its source of generation. They have the purpose to protect public health and the natural environment by reducing substantially health and environmental hazards.
They are also referred as "decentralized wastewater treatment systems" because the main technical challenge is the adequate choice of a treatment and/or disposal facility.[2][3] A commonly used acronym for decentralized wastewater treatment system, is DEWATS.[3]
