The purpose of the statute is to give water districts, not the Board, the authority over water fluoridation. Here, the resolution is invalid as applied to Lakewood because it does not allow the water district to decide the issue of whether to fluoridate its water systems as provided for in RCW 57.08.012. No majority vote of the commissioners takes place. No vote of the electors (water users) within the water district takes place. The resolution deprives Lakewood of its specific statutory power and discretion provided under RCW 57.08.012. The resolution is also invalid and ineffective as applied to the private water companies (Parkland Light). A local regulation that conflicts with state law fails in its entirety. See Adams v. Thurston County, 70 Wn. App. 471, 482, 855 P.2d 284 (1993) (<HOLDING>); see also Employco Pers. Servs., Inc. v. City
