The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Yes, a septic tank riser can replace a concrete septic tank lid. Risers are designed to replace various types of septic tank covers, including concrete, metal, and fiberglass, to provide easier access for pumping and repairs. While a plastic riser makes future access more convenient, the initial replacement can be difficult because concrete lids are very heavy, so it is a job best left to professionals. Once installed, you will need to be cautious around the riser during yard work, such as mowing, to avoid causing damage.
