The Federal Emergency Management Agency (FEMA) recommends basement waterproofing with a water alarm and "battery-operated backup pump" as a preventive measure against the high ...

[15] In areas where storm and sanitary sewers are combined, and there is the risk of flooding and sewage backing up, backwater valves in all basement drains may be mandated by code and definitely are recommended even if not ...
Installing sub-membrane depressurization radon mitigation systems, which vacuum radon from under a membrane that covers the ground used in crawlspace foundations; Installing a radon sump system in the basement; Sealing floors and walls (not a stand-alone solution); and; Installing a positive pressurization or positive supply ventilation system.
Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.
