Said Town is hereby authorized and empowered under any vote hereafter had for that purpose, through the Selectboard, to take, in addition to the water rights and appurtenances thereof, already owned or acquired by said Town, the waters of any fountains, springs, ponds, or streams for the purpose of affording said Town or any of the inhabitants of the Town of Chester a supply of water for fire, domestic, and other purposes, and may acquire the same by purchase or by right of eminent domain, and in like manner may take and hold such real estate as may be necessary for preventing the pollution of the water supply of said Town water system, provided that said Town shall not take water nor a supply thereof, so as to deprive an owner of water of an amount sufficient for his or her domestic and agricultural uses, without such owner's consent.
