NOTTINGHAM. 



HISTORY. 



The farm was started about the year 1880, and 

 has from time to time been extended to meet the 

 needs of a growing population and to allow for the 

 inclusion of the other places hereinafter referred to. 



In the evidence given to the Commission on 

 May 8, 1901, by the Hon. T. H. W. Pelham, 

 Assistant Secretary to the Board of Trade, in 

 charge of the Fisheries and Harbours Department, 

 reference is made to the pollution of salmon rivers 

 and specimen cases are quoted in which the Board 

 of Trade have communicated with the Local Gov- 

 ernment Board. In July, 1896, the conservators 

 called attention to the serious destruction of fish 

 in the river Trent, " thousands of fish of all kinds 

 for many miles " being killed. I have been in- 

 formed that this took place 3 or 4 miles above the 

 outfall of the effluent from the sewage farm. A 

 representation was made to the Local Government 

 Board in the matter, and again in 1898 in connection 

 with an application by the corporation for a Pro- 

 visional Order to enable them to acquire additional 

 land for a sewage farm. In 1899 and 1901 the 

 Local Government Board sanctioned loans for the 

 sewerage scheme on condition that the town council 

 would not at any time allow unpurified sewage to 

 pass into the river. 



REPORTS TO THE ROYAL COMMISSION. 

 Conservancy. — The number of 

 The Sewage. water-closets connected to the 

 sewerage system is 10,850 ; there 

 are also 40,550 tub-closets, 2,334 waste water-closets 

 or slop-closets and 300 midden privies. In the case 

 of the tub-closets the greater part of the urine is 

 emptied down the backyard gullies and goes to the 

 sewers. Combined. — All storm and surface water 

 goes to the foul-water sewers. Many of the streets 

 are paved with stone setts — a fact that probably, 

 partly, accounts for the comparative absence of 

 sludge on the farm. Mixed. — Approximately three- 

 sevenths of the total flow consists of refuse from 

 bleach, dye and bone works, wool-scouring, breweries. 



laundries and fellmongers ; the bleach and dye 

 effluents preponderate. The refuse is not treated 

 by the manufacturers previously to leaving the 

 works. Subsoil Water. — Owing to the reconstruction 

 of the sewers there is little subsoil leakage. The 

 Bry-weather Flow is about 7,000,000 gallons per 

 diem. Storm Flow. — About 10,000,000 gallons is 

 the limit that can be treated on the farm, this being 

 the utmost that the carriers can take. The Water 

 Supply is about 20 gallons per day in summer and 

 about I65 gallons in winter, obtained from deep 

 wells in the new red sandstone. The average annual 

 Rainfall for the past thirty-two years is 25 in. The 

 area of the city is 10,935 acres, but no mention is 

 made of the Drainage Area. Flushing. — In the low- 

 lying districts the sewers are flushed systematically 

 by means of movable flushing tanks. Stay in Sewers. 

 — The time taken by the sewage to reach the pump- 

 ing station from the centre of the city is about one 

 hour, and from the pumping station to the farm 

 about two hours, the Distance to the farm from the 

 pumping station being about 3| miles, equals 5 miles 

 from the centre of the city to the farm. Sewer 

 Capacity. — The size of the main outfall sewer to the 

 farm is 5 ft. 3 in. by 5 ft., laid at a gradient of 1 in 

 2,455, and having a capacity when running full of 

 2,698 c.f.m. There are four Storm Overflows, one 

 discharging into the river Leen and three into the 

 river Trent. They come into operation when the 

 rainfall exceeds Jin. in twenty-four hours. Screens. 

 — About two-thirds (say, 4,500,000 gallons) of the 

 sewage is screened by upright bars set 1 in. apart — 

 the screen is intended to protect the pumps. The 

 sewage gravitating to the farm is not screened in 

 any way. The Pumps deal with two-thirds of the 

 sewage, lift it about 15 ft., and force it to a chamber 

 on the outfall sewer | mile from the pumping station. 

 The rest of the sewage flows to this chamber by 

 gravitation, and the whole of the sewage then 

 reaches the farm in like manner. About six cart- 

 loads per week of Screenings are dealt with by the 

 destructor. The Analyses, both chemical and
