Harties, Metsi a me – “My Harties, Metsi a me – “My water”water”
Problem StatementProblem Statement• 700+ Mega Liters of purified sewage p/d• 280+ tons of phosphate p/a.• Depleted riparian variation & in-stream habitat• Shrinking wetlands• Toxic microcystis algal blooms• Exotic water plants (Hyacinths)• Exotic fish (Carp, Barbel, Canary Kurper)• Distorted food web and fish population• Depleted diversity in catchment and dam• Impacts from Desertification / Social Drought

OOperational perational ChallengesChallengesTTiming 3 years extensive implementation program iming 3 years extensive implementation program towards institutional development:towards institutional development:
• Regulate recreational use and implement RMP• Biomass management, labour vs. mechanised• Establish artificial vegetation – floating wetlands (Resourse Q uality
Objectives)• Point source vs. catchment management• Water allocation: – fluctuating level & Operating rules
– Socio Economic impact balanced with G&D Alternatives
• Research & Development• Interdependencies• Practical implementation• Cost benefit analyses

VermicultureVermicultureWhy do we need VermiCulture?• The average person produces approximately 1 ton organic waste/year• Vermiculture = most effective means of waste management • Vermiculture using compost worms can achieve waste elimination and
value added conversion on the same site forever.
Vermiculture: A Solution for Organic Waste Vermiculture can be utilised as a solution for the treatment of organic waste in the following sectors:•Domestic Agricultural•Industrial Commercial
Value added products derived from Vermiculture•Solid vermicast (Organic Compost)•Liquid vermicast (Organic Liquid Fertilizer)•Surplus worms for further process enhancement

Shoreline VegetationShoreline VegetationObjectives: Re-establish shoreline vegetation along the rivers and dam to enhance micro habitats for fish, control pollution and prevent
erosionDeliverables• Preparation of shoreline for planting when water level
drops• Large portions of Magalies River has been prepared for
rehabilitation.• Plant species have been identified & are collected from
local rivers & alternative wetlands.
Challenges• Full scale planting will
commence as soon as the dam water level drops. (September to November)
• Educate Local Land Owners as to shoreline rehabilitation requirements.
• Excessive hyacinth growth

Sediment Removal and Sediment Removal and ManagementManagement
Objectives: Reduction of internal nutrient load in the dam by means of sediment removal in an environmentally safe manner.
Deliverables• Detailed analyses of sediments completed• Pilot project – Elands Mine (jelly layer) & Oberon• Evaluate potential uses of the nutrient enriched silt material within
environmentally & economically sound practices
Challenges• Develop economic viable
sediment recovery practices (from the dam)
• Source willing local partners to use material
• Acquire land for sediment recovery
