Abstract
Stormwater pollution is a major problem in many of the areas where it is present.
Due to the changing nature in terms of quality and quantity of stormwater, which has its
origin in many different places, it is difficult to control and identify the source of
pollution.
Some of the pollutants present in stormwater run-off include oxygen-demanding
substances, suspended solids, trace metals, toxic organic compounds (eg. chlorinated
hydrocarbons), nutrients, refuse, plastics and pathogenic bacteria and viruses.
This thesis identifies and discusses the problems in the Lourensriver catchment area, and
produce practical solutions to decrease the pollution.
The report consists of four sections.
Part I :
Part 2 :
Part 3 :
Part 4 :
Evaluation of the existing area and identification of the problem.
Literamre study.
Control of Stormwater ie. storing, treatment and disposal.
Presencation of steps to be followed to rectify the problem.
If the findings and recommendations are followed, it should make
a positive contribution to the wellbeing of the catchment area. The findings of this report
could also be applied to areas with similar problems.
The following recommendations are made for the Lourens River:
" Monitor and strict implementation of the Wateract (1936).
" In the Lower zone, pollution can be diluted and flushed out by ways of the
closure of Melkschloot.
" Design of any new development must take place in such a manner so as the
stormwater discharge after development will be of the same quality and quantity
as before construction.
" Creation of permeable surfaces in established areas.
" Delay of rainwater flow out of all areas.
" Construction of additional sedimentation and detention dams for the storing and
treatment of stormWater.
" Awareness programmes to inform the public and industry.
" Implementation of preventative measurements.
" Establishment of controlling body's to ensure co-ordination betvieen various
institutions and local government.
" Monitor of run-off from industrial and agricultural terrain and identifying of
unlawful practices.
Strict anti-littering and dumping actions.
Placing of waste storage bins in residential and industrial areas.
Permits for the usage of poisons and the monitor there off.
Encouragement of cleaning up actions and groups.
Encouragement and increase of street cleaning operations.
Construction of effective catchment basins to remove sol ids before it ends up in
the stormwater pipes.
Regular cleaning of catchment basins.
Regular flushing of stormwater pipes.
Construction of marshlands.
Construction of reedbeds.
