WHAT IS A RECONCILIATION STRATEGY?

• Strategy or plan to ensure current and future water

requirements are in balance with available water resources

over planning period

• Basic assessments answering the following questions:

• Is water availability adequate to meet water requirements?

• Do we at this stage/time already need to make provision or plan for

interventions?

• What can be done to balance water requirements and water

resources availability?

SUMMARY

• Project area population is approximately 2 million people in

2011, growing to 2.5 million in 2040

• Sand catchment represents 51% of the population and

Mogalakwena 29%

• Residential water requirement is estimated to increase from

105 million m3/a in 2011 to 137 million m3/a in 2040

• Projection is sensitive to water loss reduction assumptions,

but planning information is inadequate

• Sanitation is far below RDP standards, but water implications

for upgrading have not yet been included

METHODOLOGY OVERVIEW

• Identify intervention options and measures from previous

studies

• Prepare Starter Document – Distributed to SSC members

• Screening workshop (SSC 02)

• Identify advantages and disadvantages based on current

knowledge

• Undertake strategy level comparisons of preferred options

• Costs

• Environmental and socio economic impacts

• Engineering feasibility

• Yield potential / requirement reduction

• Formulate scenarios to balance water requirements and

availability until 2040

• Reconciliation Strategy

Page 40: DEVELOPMENT OF THE RECONCILIATION STRATEGY FOR THE …

40

SCREENING WORKSHOP OBJECTIVES

• Present and discuss the list of intervention measures as

obtained from previous studies

• Add additional intervention options

• Select preferred options / intervention measures to be

further evaluated

• Obtain consensus within SSC on:

• Options to evaluate

• Level of further investigation

Page 41: DEVELOPMENT OF THE RECONCILIATION STRATEGY FOR THE …

41

TYPICAL INTERVENTIONS

• Management interventions

• WC/WDM

• Eliminating unlawful water use

• Optimal system operation

• Removal of IAPs

• Transfer of water allocations (Section 25 of Water Act)

• Compulsory licensing

• Infrastructure development

• Groundwater development

• Water re-use (wastewater reclamation)

• Augmentation schemes (e.g. inter-catchment transfers)

• Surface water development (e.g. storage, river abstractions)

Page 42: DEVELOPMENT OF THE RECONCILIATION STRATEGY FOR THE …

Page 43: DEVELOPMENT OF THE RECONCILIATION STRATEGY FOR THE …

45

WHAT IS WC/WDM?

Water Resource Management

Distribution Management

Consumer Demand Management

Return Flow Management

Water quality management Customer education - reduce wastage Rehabilitation of water source Storage optimisation

Pressure management Metering: water balance per zone, inaccuracies, smart meters O&M of assets: ageing infrastructure Loss reduction: leakages, inspections

Retro-fitting

Effective billing: billing, collections

Policy and regulation enforcement: free basic water, indigent register

Minimising infiltration

Minimising pollution

OVERVIEW OF QUALITY AND QUANTITY

* Only WwTW within Limpopo WMA North

Description Number

Total number of WwTW in study area 21 plants

Total capacity 81 Mℓ/d

(29.4 million m3/a)

Total number of WwTW with river discharge 13 plants

(29.7 million m3/a)

Number of plants < 2 Mℓ/d 11

Number of plants 2-6 Mℓ/d 6

Number of plants > 6 Mℓ/d 4

70 - 100% high to critical risk 13

50 - <70% medium risk 5

0 - <50% low risk 3

Page 57: DEVELOPMENT OF THE RECONCILIATION STRATEGY FOR THE …

65

RECOMMENDATIONS

• Most WwTW in study area are small or medium sized plants

(< 6 Mℓ/d) and in remote/rural areas

• Lack of effective O&M: Poor Cumulative Risk Rating (CRR)/Green

Drop scores

• Construction and lifecycle cost of advanced processes are very high

(short lifecycle if there is lack of maintenance)

• Industries and mines can use advanced technologies to produce

process water

• Sustainable solution is to upgrade current WwTW, operate and

maintain to produce good quality effluent

Possible intervention options

WC/WDM • Domestic (rural)

• Irrigation

1-2%

5% Phased in over 5-10 years

Eliminating unlawful

use & compulsory

licensing

• Irrigation ± 5.2 3-4 years

Groundwater

development

• Ga- Phahladira

cluster area

• Ga-Seleka area

> 1.24 To be further investigated by study

team.

Removal of invasive

alien plants (IAP) • Domestic/irrigation < 1.2

IAPs reduce stream flow. If removed,

increase in stream flow does not relate

to available yield.

Increased river

abstraction • Domestic

Only recommendation – to be further investigated by study

team.

Surplus water from

the ORWRDP 2B (via

Pruissen)

• Domestic

Only recommendation – at this stage no surplus water

expected. ORWRDP water requirements to be revised at

later stage to determine if surplus water is available.
