If that is your sump pump line, you have all kinds of options!
You could add a tee by the house (and two valves) and give yourself the option to run well water down to the lake. Then you could water your new grass, rinse off kids after they get sandy on your beach, clean fish OUT of your kitchen, etc.
[I might also add one of those spring-loaded brass pressure relief valves ($15?). Just in case someone closes both valves down by the lake and your water well pressure can exceed the rating of your pipe.]
Good luck on the "farm to home" conversion project! We have a farm about 45 minutes away from our home in town and I want to keep developing family projects at our place too.
