    •41 from one of the mine adits is also fdtered and the pH. value raised from 6 to 8 by the addition of soda ash. Although there are some houses in the higher parts of the town which appear to receive a somewhat scanty supply during the summer months, the resources of the Company are said to be capable of providing an adequate supply to the whole of the Borough, and also to meet a demand to supply certain adjoining areas. Launceston. The Corporation control the water undertaking for the Borough, the water being obtained from the Came Down stream and conveyed to a fdtration and chlorination plant. The normal demand for water is said to be maximum 230,000 gallons per day and minimum 180,000 gallons per day. The actual flow of the Came Down stream is not known but it is estimated that the maximum yield is between five and six million gallons per day and the minimum yield 600,000 gallons per day. The reservoir has a capacity of 490,000 gallons at 585ft. O.D. which is equal to a 2^ days supply. Apart from one or two outlying farms the whole of the Borough is served by a piped supply and the resources of the Borough are said to be capable of meeting a demand to supply the whole of the Launceston Rural District. Liskeard. The Corporation has its own water undertaking. The source of supply being the Siblyback and Crylla streams wdth a dry \v-eather flow in the neighbourhood of 1,000,000 gallon per day. The present consumption for the Borough is said to be 260,000 gallons per day and the filtration plant is capable of dealing with 312,000 gallons per day working at full capacity. There are two concrete tanks with a capacity of 470,000 gallons used as settling tanks, and two filtered water tanks of 300,000 gallon capacity at 592ft. O.D. The water after filtratfon, liming and chlorination is distributed by gravitation to supply practically the whole of the Borough. Lostwithiel. The Borough has at present tw'o sources of supply known respectively as The Ford System and the Collibeacon and Millham System. The yield from the springs supplying the Ford Systems appear to have given rise to anxiety during dry seasons and the encrustation of the mains is considerably reducing the flow. The average daily yield from all sources other than w’ells is said to be 50,000 gallons per day, and the total consumption of water is approximately 57.000 gallons per day. It would appear that there are times when these sources are insufficient to meet the requirements of the areas they are intended to serve which comprises some 90 per cent, of the population, the remainder of which rely upon shallow- wells for their water supply. A scheme is being prepared to augment the existing supplies by collect- ing w-ater issuing from an old iron mine in Churchpark Wood and pumping to the existing reservoir known as St. George Park reservoir. The yield from this source is expected to be about 72,000 gallons per day. Penryn. (See Falmouth Borough). Penzance. The water undertaking is controlled by the Corporation and the whole of the Borough is served by a piped supply.
