Over the last several years, the Metropolitan Wastewater Department (MWWD) has built an extensive library of loop drawings for all of its operating facilities created through capital improvement project (CIP) work.  It is the intent of MWWD, especially the Operations and Maintenance (O&M) Division, to maintain and keep current existing loop drawings. These guidelines are provided to assist consultants, contractors, and City staff with the creation or modification of loop drawings.
