We have been using this diaper service for the past year and a half and everyone has been very happy with it. Each week we get a bag of very clean, fragarent free, soft cotton diapers that we use with cotton/plastic wrappers (sold in many places and by this diaper service). It is very easy to use cotton diapers and they even provide a diaper pail. No washing is necessary, just flip the poopies into the toilet (optional but eliminates smells) and drop the diaper in the pail.
The environmental debate between cotton and throw-away diapers is similar to paper versus plastic grocery bags. Here in Seattle we have more issues regarding waste and landfill space rather than water issues. I like knowing that i'm not throwing human waste untreated into land fills where they might leach into water sources.
Annually, cotton diapers also cost less than throw-away. No creepy chemicals touch my baby's precious bum (like the weird absorbant gel in disposables) and she has never had more than a spot or two in the diaper rash experience.
Final big plug for cotton diapers: kids who wear cotton diapers potty train earlier.
