WASTEWATER MANAGEMENT 19 September 2018 PRESENTATION TITLE Presented by: Name Surname Directorate Date

CONTENTS Introduction South African Water Services Regulation Municipal Impacts WWTW Impacts Tools for the sustainability of WWTW Conclusion

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

MUNICIPAL CHALLEGES

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

SOUTH AFRICAN WATER SERVICES REGULATION

TOOLS FOR THE SUSTAINABILITY OF WWTW’s

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.

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 "

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

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

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

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

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
