In My Opinion
not only can it cause excess nutrient load it can also cause solids to build up in the drain field.I'll give you a reason why it's environmental. If you waste water and you're on septic, you're going to overload the system which can cause excess nutrient load in the discharge. If you over-water your lawn, you're causing runoff which carries fertilizer and other pollutants to go down to the waterways. Oops, that's two reasons.
My system at my house was replaced 5 years ago. I oversized everything for the house.
My house required a 1000 gallon septic tank, I installed a 1500 gallon split tank system.
My drain field required a 125ft single run down my field, I installed two 100 ft runs.
That right there is why I got so pissed off when the state pulled that septic users fee to help with the cost of maintaining the city systems.
Nobody in the state offered to help me out with my 15,000 dollar replacement.
