* Daily treatment capacity is based on influent values equal to or less than
domestic sewage (grey and black water combined). The influent values below
is the maximum organic loading for the above treatment capacities. For influent
with heavier loadings, please contact our office or your nearest Maskam Water
Dealer to assist with sizing the correct plant for your application.

As custodian of South Africa’s water resources, the Department is responsible for the
formulation and implementation of policies governing this sector. These policies are
aimed at guiding service providers, equipment manufacturers and purveyors of
innovative and proven technologies.
The Department is not involved in the provision and treatment of water or
wastewater, nor is it involved in the purchase of water or effluent treatment
equipment, nor is it responsible for building Water Services infrastructure. As a result,
the Department cannot endorse, recommend or promote a specific product in
the market, or brand name equipment or technologies.

I am giving you feedback on the meeting that we had regarding
your Waste Water Treatment Plant.
Unfortunately, SABS does not have any South African National
Standards that are applicable to this product. I have taken the
time to research if there is also any other body that can assist in South
Africa in either testing or giving some other type of approval equivalent
to the SABS Approval but I have not been successful. Its not only this
type of a treatment plant that we do not have standards for, but also
any other type of water treatment plant or related treatment plants.

Municipal By-laws
More and more municipalities and local governments support
on-site treatment as part of solving the national water shortage
and to extend the life of overloaded waste water treatment
plants and –networks.
It might be wise to familiarise yourself with the bylaws of the local
council.
Urban use of private Waste Water Treatment Plants
Urban use of private Waste Water Treatment Plants
The Western Cape Government
supports on-site treatment and re-use
of waste water
"Waste water treatment closer to source becomes a cost effective
and energy efficient alternative to unlock economic opportunities,
eradicate the housing backlog, fast track access to sanitation
services in informal settlements and at the same time reducing the
potable water consumption by 60% by the re-use of effluent for
flushing toilets, food gardening and the irrigation of neighbourhood
landscapes."

Lekki Island, Lagos
Treated water goes into storm
water system which feeds a lake.
Irrigation water is pumped from
the lake
Excess treated water can be stored
and re-used for the benefit of the
community, i.e. irrigation or other non-
potable uses.
Settlements
Not a single drop of
potable water is needed
to give this community
dignified sanitation!!!
Black & grey
water is treated
Treated water is used for toilet flushing
1. Black water 2. Grey water from
washing clothes,
bathing, etc
4. Small gravity fed holding tank for treated effluent
that will be used for toilet flushing
5. Treated water returned to the
community for toilet flushing. 12V
solar powered pumps can be used
3. Fusion
6. Holding tank for excess treated
water to be used for irrigation
Black and grey water from a
community can be treated on site
and re-used for toilet flushing while
excess water can be used for
irrigation. Note that NO potable
water is needed to deliver
dignified sanitation to
communities..

Parallel installation of Fusion
Multiple Fusions can be installed to increase capacity. Plants can be added
any time in future, should the need arise. Staged installation may assist
customers with cash flow.
