Additional Best Practices for Septic Tank Systems and Public Wastewater Systems (See Drinking
Water (On-Site Water Supply and Public Water Supply) section above)
• Do not drink any well, cistern, spring, or surface water on the property or within the vicinity until the water has been tested for microorganisms and chemicals and the water has been found to be consistent with drinking water quality regulations.
• Do not use the on-site sewage system until the water level in the ground is beneath the drainage area of the system and the ground has dried out.
• Have professionals in on-site sewage systems determine if the system is operable or if it has been damaged and needs to have necessary repairs made.
• If sewage has come to the surface of the ground or backed up into the structure, use appropriate cleaning and decontaminating procedures while wearing necessary personal protective equipment.
• Flush out any silt or debris which may have entered the system prior to using it.
• Examine all electrical equipment to determine if it is functional.
• Secure the septic tank manhole cover and all inspection ports.
• Have the septic tank and other ancillary equipment pumped out if needed by trained professionals.
• Where sewerage systems or the network of pipes carrying the wastes to the sewage treatment plant have been damaged, it may be necessary to temporarily install portable chemical toilets in a given area. These units should be cleaned thoroughly frequently and kept under constant supervision. The individuals using them should have access to immediate hand-washing facilities in order to prevent the spread of oral-fecal route diseases.
