No water treatment exists at the moment. We have been using this lake water for over 20 years and get our drinking water from country club golf well. Our lake water is tested many times during the year by association and has never had any problems yet.
I was planning to make my well water primary and lake secondary (backup), but after testing my well water and if I need to install some type of filter system or chlrone system and will revers my decision and make my well the secondary (backup) source of water.

I design and build systems for using lake water as small public water supplies. The systems have to meet US EPA Surface Water Treatment Rule requirements and be approved by the state.
I have built systems for 500 to 20,000 gallons per day. They are completely automated. You have to keep the chlorinator supplied and change the filters every few months.
The systems consist of cartridge filters and disinfection.
Good well water is the preferred solution but if it requires extensive treatment to make the well water good you can safely use good lake water.
Lake water is almost always free of iron, manganese, hardness, arsenic, radon and other things often found in wells.
If you have a good lake supply you can water your lawn with untreated water and treat only the household water that is usually less than 300 gallons per day.
Where are you located? How big is the lake?
