§3.157. Water quality. — Inbound Citations

(g) Housing facilities must be equipped with disposal and drainage systems that are constructed and operated so that animal wastes and water, except for water located in pools or other aquatic areas (e.g., ponds, waterfalls, fountains, and other water features), are rapidly eliminated so the animals have the option of remaining dry. Pools and other aquatic areas must be maintained in accordance with the regulations in § 3.157. Disposal and drainage systems must minimize vermin and pest infestation, insects, odors, and disease hazards. All drains must be properly constructed, installed, and maintained so that they effectively drain water. If closed drainage systems are used, they must be equipped with traps and prevent the backflow of gases and the backup of sewage. If the facility uses sump ponds, settlement ponds, or other similar systems for drainage and animal waste disposal, the system must be located a sufficient distance from the bird area of the housing facility to prevent odors, diseases, insects, pests, and vermin infestation in the bird area. If drip or constant flow watering devices are used to provide water to the animals, excess water must be rapidly drained out of the animal areas by gutters, pipes, or other methods so that the animals have the option of remaining dry.
