8. PUBLIC SWIMMING BATHS. Two open-air public
swimming baths are provided in the area and serve the general public
during the summer period, usually from May to September.
The Vale Farm Pool is 55 yards long and 25 yards wide with a
maximum depth of 9 feet and has a capacity of 400,000 gallons of
water which is obtained from the Colne Valley water supply. The
Pool is constructed of mass concrete and lined with glazed bricks.
The water is filtered through Candy Pressure Filters and has a complete
change every 4½ hours, the circulation being effected by 20 h.p.
pump with a stand-by 15 h.p. pump. "Breakpoint" chlorination is
effected and an average consumption of approximately 3 lbs. per hour
of chlorine. The water is then neutralised by the addition of soda
which gives an approximate pH factor of 7.5 which indicates slight
alkalinity. The bathing load is approximately 1,500 and the basket
room system of changing is in operation with cubicles surrounding
the Pool. A Cafe is provided for refreshments and the catering let
out to a Caterer on an annual basis.
The Kingsbury Pool is situated in Roe Green Park in the
Kingsbury Road and has a length of 55 yards and a width of 25 yards
with a maximum depth of 10 feet. The capacity is 464,000 gallons
but in this case there is a foot trough surrounding the Pool and also a
Children's paddling pool. The water is supplied by the Colne Valley
Water Company and is circulated through Permutit Pressure Filters
and pumped by means of two 15 h.p. pumps and a complete change
of water is effected every five hours. Chlorination is again on the
"breakpoint" system and the same dosage and neutralisation
arrangements. The Pool at Kingsbury is constructed of reinforced
concrete and again is lined with glazed bricks. The capacity of this
Pool for bathing is approximately 2,000, but there is a greater
spectator area here than at Vale Farm. The basket room system is
