Tools for the sustainability of WWTW
Conclusion

3. INTRODUCTION
Most of the municipal waste water infrastructure is ageing
It operates above capacity
There is poor operation and maintenance
Municipalities do not have capacity (financial and human)
Most WWTWs are vandalised due to lack of security
DWS supports municipalities in capacity building, MWIG and RBIG
Where Metros have a water services provider (Jo’burg Water; ERWAT), the infrastructure is managed better
The only challenge is management of sewer network that is outside the mandate of these municipal entities

4. MUNICIPAL CHALLEGES

5. WWTW IMPACT Partially treated effluent Poor maintenance Vandalism
CHALLENGE(S)
RECOMMENDATION(S)
Partially treated effluent
Poor maintenance
Vandalism
Plant Design capacity
Review of the W2RAP not finalized
Non- compliance with Regulation 813
Poor sludge management
Lack of adequate fencing of the facility
Poor industrial wastewater Quality
Manhole blockages
Dysfunctional infrastructure
No signpost and access to information
Poor House keeping
Undersigned infrastructure
Poor Waste management
Non-compliance with the water Use authorisation conditions
Prioritized wastewater quality
Improve maintenance turnaround time
Adequate security
Prioritized Upgrading of the works
The review of the W2RAP must be finalized and implemented as a matter of urgency.
Avail qualified process controllers on site (Class 4 Process Controllers)
Prioritized on adequate sludge management.
Put up proper fencing
Implement and Enforce bylaws
Ensure operation and maintenance of the infrastructure
Operation and maintenance
Signpost and classification of process controllers must be displayed
improve on housekeeping and condition of the facility
The sludge drying beds and maturation pond should be lined and/or emergency dam.
Implement proper waste disposal mechanism
Enforce compliance by Municipality and continuous monitoring

7. TOOLS FOR THE SUSTAINABILITY OF WWTW’s

8. IMPLEMENT W2RAP AS INTEGRATED PART OF OPERATIONAL & MANAGEMENT SYSTEMS
The risk assessment should be conducted:
at a frequency that ensures that all spatial and temporal risks are apparent (minimum annually).
change in raw sewage or infrastructure which may affect meeting the effluent standard or sludge quality;
after significant failure of any component process in the Wastewater Balance;
a new treatment system is put into service;
a refurbished treatment system is re-commissioned;
a new network or pumping system is put into service;
a drainage zone is altered.

9. GREEN DROP IMPLEMENTATION PLAN
"(1) A practical Green Drop Improvement Plan
with compliance gaps,
actions,
responsible person,
target date,
budget;
Monitor the improvement of Implementation of identified actions "

10. WATER DEMAND MANAGEMENT
Water demand management plan to
problem statement,
magnitude of problem,,
action plan,
budget,
timeframe to address water leaks to the sewer systems
Performance of the processes

11. STORMWATER MANAGEMENT
Stormwater Management Plan to address stormwater entering the WWTW
quantify problem,
action plan,
budget,
timeframe to address stormwater problems that impact on the wastewater system
This has an effect on the performance of the plant

12. SLUDGE/ WASTE MANAGEMENT
Provide a Sludge (Waste) Management Plan that includes sludge handling ( different processes)
Classification of sludge( continuous monitoring)
Sludge treatment facility
Disposal

13. By-laws must include all wastewater regulation aspects
Compliance monitoring and enforcement of industries/ users discharging to WWTW done
Enforcement of non- complying users,

14. Implementation of developed plan eg WRAP
CONCLUSION
Implementation of developed plan eg WRAP
Compliance monitoring Enforcement of by-laws
Consider Government regulation as an enabling supporting instruments
