Structural Arrangements of Fremantle Gaol.

Drainage of the Prison within the Main Walls.

OLD SYSTEM—PLAN No. 1. The whole area was drained by two main drainage tunnels, North and South, which discharge the sewage into the Recreation Reserve and the large cesspits on the flat or gardens outside the walls. SOUTH TUNNEL.—This draIn received the drainage from Dr. Hope's house and stables, scour, and overflow pipe from Old Reservoir. Cookhouse and Yard. Pump Yard. Trial Yard—With urine of prisoners in the morning (part only). Surface Drainage of about one-half the whole area. NORTH TUNNEL.—This drain received the surface and front water as follows:— Bath Water and water from washing towels, clothing, etc., bath-house. Trial Yard.—Urine and soapy water of prisoners' pots and buckets (part only). Refractory Yard.—Waste from three bath, washing prisoners' private clothing and clothing of such of the prisoners as have contagious diseases. Probation Yard.—The drainage of urinal, the urine mixed with faeces of six closet pans, the urine and soapy water from pots and buckets. Hospital Yard.—Waste from bath, foul water from washing clothes, lavatory, pots, and night-stools. (The drains require lifting, relaying, and trapping.) Imperial Prisoners' Depôt.—The drainage from baths, kitchen, pots, and lavatories of prisoners, the drainage from the warder's private residence, and the surface drainage. Scour and Overflow pipes from the New Reservoir are connected with the drain from Depôt, and thence forward to the main drain. Female Prisoners.—The surface drainage, urine, bath water, foul water from bath-house and laundry, kitchen, etc., and the drainage from female warders' quarters. Chaplain's House.—The whole of the slop-water, bath, kitchen, wash-house, and surface waters are conveyed into the drain coming from the Female Prison. SUBSIDIARY DRAINS— Superintendent's Residence Gatekeeper's do. Chief Warder's do. The Guard-room Yard These are connected with a drain discharging into the gardens on the flat below the Prison, where there is generally a pool of foul water. Magistrate's Residence is drained by a separate cast-iron drain-pipe into the corner of the Reserve, and has to discharged slop, kitchen, and surface water. None of the drains were trapped, except that which connects the sink at the door of division opening into the Probation yard. The only ventilation of the old drains was that afforded by the two drains opening into the well outside the bath-house, and, as since discovered, the two air-shapes built in the main wall of the Prison, and supposed to ventilate the closets (4) at the North-West and the closets (4) at the South-West corner of the Division. These openings I have seen, and believe to be the cause of the bad smells so often complained of in the Hospital and at the cook-house end of the Division. It will be observed that the main drains both pass under the main building. This is radically wrong, and should be discontinued. The whole of the old drain pipes ( which may be utilised in future) ought to be taken up and relaid, properly trapped and ventilated. The urinals in all the several yards are badly constructed, entirely lacking in privacy, and ought to be connected with the drains in all cases.
