An improperly maintained septic system can create a health hazard and damage property |
Replacing a septic system can be costly— both financially and to the health of a family or neighborhood. The expense to replace a failing system can exceed $10,000. And damage to the soil and groundwater from leaking system components takes a long time to repair.
Clark County Public Health is responsible for permitting septic systems, overseeing the septic operation and maintenance (O&M) program, and reviewing land use plans.
The work of this unit is important because it helps to protect the groundwater by:
- enforcing necessary state and local regulations, policies, and procedures regarding septic system installation and maintenance
- evaluating proposed sewage treatment sites
- issuing onsite septic system permits, temporary hardships, etc.
- reviewing all septic system plans
- inspecting and approving all system construction in Clark County
- investigating failing septic systems and repairs
- presenting onsite sewage system and septic maintenance information at land use hearings and forums
- reviewing and reporting on short plats, subdivisions, commercial development and proposed regulations
- educating and licensing septic system pumpers, installers and inspectors within Clark County
- educating and informing the septic system owners about proper operation and maintenance of their systems
- working with other public agencies to monitor, improve and enforce local liquid waste policies and procedures
