The drainage is arranged on a separate system, the rain and surface water being carried to outlets on the north side of the site, the sewage to outlets on the west side; in this manner the necessity for providing sewer pipes of large size for carrying off excessive rain fall is avoided, as well as the risk which arises from the direct connection of rain water pipes, waste from cisterns with foul drains: and it becomes possible to employ sewerage pipes of dimensions sufficient to carry off the sewage without the danger of stagnation of flow and consequent obstruction which arises from the use of pipes calculated to meet the exigencies of tropical rainfall.
The foul drains are in all cases carried as directly as possible outside the hospital.
