A method of delivering a necessary amount of a component for a cementitious product to a construction site, depositing the component into a container, using the component to make the cementitious product, and then retaining residual component and material resulting from rinsing the mixing equipment. In its preferred embodiment, an empty plastic container is delivered to the site, the deliverable component is sand, and the cementitious product is stucco. The amount of sand that is needed for stucco is determined and delivered to the plastic container via conveyor belts from sand trucks sitting in the street. The sand is used to mix the stucco in mixers present at the construction site, as known in the art. Once the stucco is mixed, the mixing equipment is rinsed with water and the washout effluent is deposited in the now-empty plastic container. The plastic container is then sealed and picked up with a crane sitting in the street and emptied at an accepted waste facility.
