(Course 1) Understand Hydraulic Principles in relation to Wastewater Network Design

The understanding of hydraulics principles is fundamental in the successful design of wastewater networks. These programmes aim to increase the knowledge and understanding of basic hydraulic principles and their impact on the integrated sewerage system.

1. Flow & hydraulic design - The basic calculations relating to wastewater networks and their relevance to design and performance including: a) Area b) Volume | Undertaking the basic calculations relating to wastewater networks including: a) Area b) Volume c) Flow d) Velocity e) Attenuation f) Pipe runs g) Manhole location | The considerations to be made in relation to the hydraulic design of foul and surface water sewers, including: a) Domestic and industrial design flow rates b) Self–cleansing velocity c) Gradient d) Roughness value

2. Design of the wastewater network - The considerations to be made when designing wastewater networks, including: a) Pipe size availability b) Pipe roughness c) Current and future demand d) Cost e) Pump station requirement f) Rising mains | Current construction methods and available technology. The limitations and benefits including the time / cost implications to be considered | Design and positioning of CSOs (Combined Storm Overflows) within the network to comply with Environment Agency Standards

3. Wastewater network levelling - The basic principles and implications with regard to the wastewater network of levelling, including: a) How to use benchmarks b) Determining gradients c) Determining depth d) Determining different levels

4. Pumping - Understand how wastewater pumping stations are designed and the importance of sump design and pump selection

(Course 2) The Correct Application of Hydraulic Principles to Improve Key Operational Service Performance Commitments

As the UK water industry continues to adapt to a TOTEX model there is a need to understand the condition of assets in real-time to optimise systems, plan maintenance and better inform future design.

1. Condition monitoring - Using online and off-line monitoring of wastewater network assets including CCTV surveys, historical failure models, acoustic evaluation and “hot spot tool” for blockage mapping to quantitatively evaluate the condition of a sewerage catchment

2. The Investment prioritisation process - Using hydraulic models, condition data and customer complaints to prioritise investment in the sewer network

3. Sewer asset management tools - Understanding the importance of reliable data, solid engineering principles and accepted economic values | Using asset management tools to aid decision making regarding infrastructure maintenance, repair and renewal

(Course 3) Best Practice in Wastewater Operations

1. Proactive maintenance and assessment - Identifying areas in the network which would benefit most from scheduled CCTV surveys, jetting and de-silting programmes

2. Sewer network investigations & clearance protocols - Establishing standard protocol for all sewer investigations and blockages which ensures prompt response, effective clean-up and root-cause analysis to reduce repeat occurrences and improve customer service

3. Wastewater pumping station management - Understanding best practice in operational maintenance to ensure reliability, reduced operational costs and optimal operational effectiveness of sewage pumping stations

4. Customer complaints - Understanding how to effectively investigate and respond to customer complaints with a view to improving customer service and SIM score

(Course 4) Internal and External Flooding Response

Surveys of UK water sector customers have consistently highlighted out-of-sewer flooding as being one of their highest concerns. It is important for operational staff to have a background understanding of the different causes of out-of-sewer flooding, best practice in terms of response and the legal principles relating to liability.

1. The causes and impacts of out-of-sewer flooding - Review the impact climate change, population growth, private land use and customer behaviour has on the risk and severity of out-of-sewer flooding | Outlining the various causes of flooding, including exceptional rainfall events, pumping station failure and blockages | Understand the impact of flooding on customer’s health, finances and emotional well-being through examination of recent case-studies

2. Flooding response and clean-up - Management of assets and operators during a flooding event to reduce customer impact | Applying the Water Research Centre guidelines for best practice in the event of external and internal flooding events

3. Customer Management - Guidelines for customer communications before, during and after a flooding event | Understanding the fundamentals of liability for management of public liability claims and DG5 reporting protocols
