Water & Wastewater Asia November/December 2020

VIEWPOINT 37
NO SERVICING
AES systems are lightweight, easy to handle
and do not require regular maintenance,
such as the scheduled operational services
needed for older-style AWT systems.
This addresses one of the central
problems for on-site wastewater treatment
management across Asia and negates the
need to train and monitor local service
providers.

COST EFFECTIVE
These systems require less outlay for
installation - on a per-head basis - and
have significant in-built savings due to
few lifetime maintenance costs and no
electricity requirement.
This is good news for anyone from
individual consumers to governments
and water authorities, private investors
and/or PPP project managers looking
to work to strict budgets, especially in
under-developed or remote and out-lying
communities.
ALL CONFIGURATIONS
These systems are completely scalable.
Assuming soil conditions and other issues
are sorted, our systems will work perfectly
well for anything from large commercial or
multi-person situations (such as hotels and
even townships) to single-person dwellings.

AES systems can handle differing daily flow
levels, at the same site. When installed,
the system is brought up to the discharge
specification immediately (each has a
minimum 3,000-litre septic tank as a
buffer). This allows maximum operational
flexibility for a single site that may have
multiple uses and variable occupancy rates.
In comparison, some old-style AWT systems
can take up to eight weeks to get up to
discharge requirements and cannot cope
with inconsistent food and flow levels.
