Septic Systems and RWH
If you have a septic system, you may ask, what kind of an impact does rainwater harvesting have on my septic system?
The short answer is that RWH has a beneficial impact, here is why:
How water efficiency helps your septic system:
The amount of water a septic system has to process, is important. The critical component of your system is the natural biotica (living organisms that digest and treat sewage waste) in your tank. Just like you, they can only process so much food. Water conservation practices reduce the flow of water going through your septic system, giving the bugs a break. Sound water conservation practices, translate into less demand and reduced failure rates on the system. The more solids you put in, the more demand. Grease, flushable wipes, chemical solutions, coffee grounds, paper towels and pharmaceuticals are just a few of things that should never be flushed into a septic system.
Maintain your drain field
Don’t park heavy objects, like cars and trucks on your drainage field. Keep plant roots from growing into the piping system (USEPA, 2015).
By collecting rainwater and atmospheric moisture you will be keeping excess water from complicating you systems ability to process wastewater. During heavy rain events it becomes very important that your septic system is not flooded out or swamped by excessive water. Rainwater harvesting is an excellent way to reduce roof runoff to your septic system.
