On the northeast outskirts, at the south end of the
Purley Way playing fields is Russell Hill
reservoir. It was opened on 11th July 1923 by Croydon's mayor, Alderman T W Wood Roberts. At that time
Croydon Corporation was responsible for supplying the borough's
sanitation.
Croydon's population growth and finite water sources meant there was a risk that peak demand could not be met, particularly during droughts. The corporation's engineer, George F Carter, had proposed a new reservoir at Russell Hill as early as 1911, which was estimated to cost £91,000, three times the cost of the newly opened Waddon pumping station. and
World War 1 fought; the final cost was £900,000. This became
Thames Water Authority on 1st April 1974 and
Thames Water following the 1989 privatisation, who now own the c.100 year old reservoir. ==References==
