- Inland and Coastal Water Quality Committee Annual Report 2011
This annual report provides a synopsis of the activities and achievements that were undertaken by members of the Inland and Coastal Water Quality Committee during 2011. The committee provides a platform for sharing information regarding inland and coastal water quality and offers opportunities for internal and external role players to collectively seek and implement integrated solutions for water quality improvement within the City of Cape Town
- Inland and Coastal Water Quality reports
These quarterly reports are prepared for submission to the City’s Transport, Roads and Stormwater Portfolio Committee meetings. The reports inform the committee about the state of inland and coastal waters and provide feedback regarding management interventions and key projects that are intended to improve water quality in Cape Town’s environmental waters.

- Cape Town’s sustainable approach to urban stormwater management
This paper describes how management of Cape Town’s stormwater systems has evolved over the decades since the first Europeans settled here. The significant challenges facing the City as well as the modern approaches that are now being followed are also highlighted.
- Stormwater Management and Planning Guidelines for New Developments (July 2002)
These guidelines support the policy entitled ‘Management of Urban Stormwater Impacts’ and are prepared in terms of the City’s Catchment, Stormwater and River Management Strategy. They aim to facilitate the development and extension of stormwater management systems on a coherent basis within the Cape Town metropolitan area, a system that mimics nature, uses natural features in the stormwater cycle, will be an asset to the community and will function efficiently with relatively little maintenance.
- Stormwater Management on Slopes adjacent to Natural Area (2003)
These guidelines assist in the planning, design, operation and maintenance of stormwater management systems for new and existing developments in the natural/urban interface zone adjacent to the Cape Peninsula mountain chain. Cost effective, innovative solutions are encouraged, as well as solutions that are sustainable (in terms of future maintenance requirements), environmentally sensitive, and provide the most social and amenity value.
- Guidelines for Integrating the Protection, Conservation and Management of Wetlands into Catchment Management Planning
These guidelines provide a suggested Critical Path, which responsible agencies will be able to use to implement wetland management in their areas. This will help agencies navigate from (a) planning at catchment level for wetlands management and protection, to (b) implementation of wetland protection, rehabilitation and management strategies at site level.
- A practical field procedure for identification and delineation of wetlands and riparian areas
This manual, published by the Department of Water Affairs, describes field indicators and methods for determining whether an area is a wetland or riparian area, and for finding its boundaries.
- City of Cape Town Wetland Mapping Report
This report documents the process used to map (using aerial photography), classify and describe wetlands in the City of Cape Town area. This study, which was conducted in four phases since June 2007, generated an extensive spatial database that is invaluable for the management and conservation of the City’s wetlands as well as for the assessment of development proposals.
- Prioritisation of City Wetlands
Following detailed mapping of the City’s wetlands (~7 700 of them), they were ranked in priority, to facilitate their inclusion in the City’s Biodiversity Network and to guide their future management and conservation.
- Aquatic Ecosystems Water Quality Guideline
The Department of Water Affairs’ South African Water Quality Guidelines series serves as the primary source of information for determining the water quality requirements of different water uses and for the protection and maintenance of the health of aquatic ecosystems. This set of guidelines includes a set of water quality criteria for safeguarding freshwater ecosystems in South Africa.
- Recreational Water Quality Guidelines (Freshwater)
The Department of Water Affairs’ report, South African Water Quality Guidelines for Recreational Water Use,’ is essentially a user needs specification of the quality of water required for different recreational uses. It provides the information required to judge whether any inland water – rivers, streams, canals, dams, ponds and other impoundments – is fit for recreational purposes.
- Recreational Water Quality Guidelines (Marine and Coastal Waters)
This Department of Water Affairs report provides guidelines for determining whether marine and coastal waters are fit for recreational use.
- South African Water Quality Guidelines Volume 8: Field Guide
The South African Water Quality Guidelines Field Guide, Volume 8 of the South African Water Quality Guidelines series, is a compilation of all the Target Water Quality Ranges (TWQR) for the different water use sectors dealt with in volumes one to seven. These include Domestic Water Use (Volume 1), Recreational Water Use (Volume 2), Industrial Water Use (Volume 3), Irrigation Water Use (Volume 4), Livestock Watering (Volume 5), Aquacultural Water Use (Volume 6) and Aquatic Ecosystems (Volume 7).
- South African Scoring System (SASS) Version 5 Rapid Bio-assessment Method for Rivers
This paper describes in detail the South African Scoring System (SASS5) biomonitoring methodology.
- River Health Programme: South African Scoring System (SASS) Data Intepretation
Guidelines
A key aspect of the River Health Programme (RHP) is information generation and dissemination. The reporting of the results of river health assessments is thus critical to the success of the programme. As there are many river health practitioners in South Africa it is important that all make use a uniform set of guidelines for the interpretation of SASS data.
- State of Rivers Report: Diep, Hout Bay and Lourens and Palmiet River Systems (2003)
This State of Rivers Report was compiled by a team of river health practitioners from the City of Cape Town, Water Affairs, CSIR, Cape Nature and University of Stellenbosch. The report details the condition of the Diep, Hout Bay, Lourens and Palmiet river systems as well as a range of biological indicators in order to determine the current ecological health of these systems.
- State of Rivers Report: Greater Cape Town’s Rivers (2005)
This State of Rivers Report partners with the above reports, and together covers all the rivers in Cape Town. The two reports provide a baseline for the ecological health of all rivers in the Cape Town area.
