16 to 25 feet. The water from the Fedderate gathering 
ground, which is 760 acres in extent, at 250 to 400 feet 
elevation, is treated by mechanical filters. The Town 
Council control the water rights, but do not own the areas, 
which are partly arable and partly pasture land. 
Turriff obtains its water supply from the Barnyard Estate, 
of 318 acres, purchased by the Burgh in 1903 for £6000, 
all arable land, except 6 acres of plantations, and situated 
between 400 and 600 feet elevation. About 100 acres, 
as well as the main buildings, are below the reservoir, there 
being only a small house and steading above it. The 
- collecting drains are 10 feet or more below the level of 
the ground; and the water is naturally filtered by gravel 
before reaching the drains. No surface water is taken. 
The Burgh has an emergency supply from a collecting 
reservoir on Delgaty Estate, but it is only used for flushing 
drains, except in rare cases of severe drought. The gather- 
ing ground here is about 100 acres in extent, and is 
situated at less than 350 feet above sea-level. 
Keith obtains its water supply from gathering grounds, 
which are not owned by the Town Council, at Balloch Hill 
and Cairney, 350 acres in extent, between 743 and 783 
feet elevation, all hill pasture except 50 acres of arable 
land. The water is entirely derived from springs. On 
Balloch Hill area there are no houses or farms, and the 
water is passed through filtering screens. On Cairney area 
there are several farms and crofts, and the water is passed 
through gravel filter beds. 
Peterhead obtains its water supply from three im- 
pounding reservoirs at Forehill, with a total capacity of 
16,000,000 gallons. The gathering grounds, of which 
the Town Council only own about 8 acres, are mostly 
arable land, with houses and farm-steadings, and are situated 
between 130 and 200 feet elevation. The water is collected 
in pipes from streams on the gathering ground, and is 
passed through sand filter beds.
