“Water and Wastewater Treatment” training programme, Singapore, August 2003.
In August 2003,
Ing. Marco Cremona participated in a two-week training programme in water
treatment sponsored by the Small Islands Developing States Technical
Cooperation Programme (SIDSTEC) of Singapore.
The Singapore Cooperation Programme (SCP)
was established in 1992 with the aim of providing technical assistance and
information dissemination to other developing countries. The SCP brings the
various technical assistance programmes offered by Singapore
under one framework. Since 1992, Singapore
has sponsored training courses and study visits for over 22,000 officials from
some 150 developing countries in Asia-Pacific, Africa, Middle East, Latin America and the Caribbean. The administrative
body in Malta for the SCP programme is the Ministry of Home Affairs which is also
responsible for the selection of the participating candidates.
Ing Cremona was
selected by the Ministry of Foreign Affairs to represent Malta,
received theoretical and practical training on various water management
techniques, ranging from planning, design and construction of drainage systems
to water conservation and water demand management to wastewater treatment and
re-use.
The course was delivered by officials of
the Public Utilities Board (PUB) which is the comprehensive water authority in Singapore.
PUB is responsible for the stormwater drainage network, the potable water
supply system and sewage treatment in Singapore.
Singapore boasts the lowest rate of unaccounted-for water in the world with a
figure of less than 5% of total production. Other milestones are the re-use of
treated sewage in augmenting the potable water supply (referred to as Newater)
and the operation of a state-of-the-art PUB-One one-stop customer contact
centre for all of PUB’s operations.
The training
course comprised a series of lectures and site visits to water treatment
facilities over the two weeks from the 11th to the 22nd August 2003. The topics covered aspects in water and wastewater management such
as flood control, potable water treatment and quality monitoring, water demand
management, sewerage works and water treatment plant design and operation.
The
highlight of the training course was a visit to one of the Newater facilities
where wastewater is treated to produce ultra-pure water suitable for use in the
semiconductor industry and which is also used to augment the potable water
supply. The treatment process uses advanced membrane technologies such as
Microfiltration, Ultrafiltration and Reverse Osmosis, followed by disinfection
using ultra-violet technology. Acceptance of Newater for human consumption
followed two years of testing, in which time 20,000 comprehensive tests were
undertaken. By 2012, 25 % of Singapore’s water supply will
come from a combination of desalinated water and reclaimed water.
