Plumbing systems that are energy and water-efficient begin with a thoughtful design. Ideally, plumbing fixtures should be placed close together and modern materials should be used. Generally, plumbing designs include two systems: one that supplies water and one that takes away waste. Also, the drain system is equipped with vent stacks, which let the drains breathe and allow sewer waste to move through the sewer system. In addition to planning and designing storm drainage systems, hot and cold-water systems, and sanitary sewer systems, we also review how to coordinate these systems with architects and structural engineers. We have the technical expertise to develop initial design concepts and draft recommendations based on preliminary design data as well as to detail and install plumbing and drainage.
