Abstract: A sanitary water barrel for use on construction job sites and the like. This system employs a substantially standard barrel that has been modified to accept a replaceable plastic liner. The exterior of the water barrel near the upper end thereof is provided with radially extending hook members to engage with apertures placed near the upper periphery of a replaceable liner. The liner is provided with an integral spout which is passed through an opening in the side wall of the barrel. A weight- and spring-biased closure mechanism normally bears against the spout of the liner as it leaves the barrel causing the closing of the spout and therefore prevents water leakage therefrom. Water is caused to flow by raising a lever on the valve when desired. These special liners can be fabricated in a roll type fashion similar to garbage bags with perforated tear lines provided to separate each individual liner unit.
