We bought this toilet mostly because of its good reviews and high efficiency, at 0.8 gallons a flush.

@Eve OliverYou need to purchase the "least efficient" toilet they sell..1.6 gallons per flush or more...I learned early that more water is needed to flush solids down old sewer pipes.

A lot of the cost of water is just the base cost--$12.40 to read the meter and $21.29 for base sewer cost for 0-4,000 gallons. 

These last for about 4 years or 400,000 gallons.  

It lasts for about 4 years or 400,000 gallons and greatly improves water quality.

A septic tank is a holding tank , then 50 gallons of water goes in and displaces 50 gallons into the drainfield 

All they needed was 1 gallon of paint and some new metal posts for the adjustable shelves in the kitchen cabinets as a couple of the plastic ones had broken with her heavy mixing bowls.And a small area where a previous handyman (maybe them) had done an ugly job on a plaster repair.It is a grand slam home run most of mine are only triples

Let's say it's a 1,000-gallong tank at 70% capacity and you paid $2.50 per gallon.
