Background 3 East Midland Cities: Highway and Land Drainage Asset - - PDF document

1 Highway and Land Drainage Asset Management Initiatives

Alan Adcock Head of Highway Management

Background

3 East Midland Cities:

• Face similar Highway Drainage Issues
• Have Complementary Experience
• Committed to Working Together
• Opportunity for Best Practice for Highway

Drainage in Urban Areas

Leicester Asset Data

• There are over 40,000 gullies recorded

although data on footway drainage is limited

• Recently a great effort has been put into

collecting gully details using GPS

• Hot spots records – hard copy of flooding

incidents

Leicester: Blackbird Road

Left: trying to clear leaves Below: the answer

Leicester: Gully Emptying – GPS

• Gully machines

fitted with GPS

• Masternaut –

Web based GPS System captures the information

• n site

Leicester: Data Collected

2 Leicester: Information

• Records if gully pot is modern style or cast iron
• Is the gully currently working
• Is there a high concentration of parked cars
• Has the frame got a defect
• Building the asset data on footway gullies this

information is very poor.

Leicester: Map Based Results

Plan: Proposed Tasks

• The 3 Cities need to evolve as we

progress but at this stage the following

• utputs are envisaged
• Each task is designed to have a tangible
• utput that can be shared with other

authorities

3 Task: 1

Bring records of existing situation up to a common standards

• Maintenance records – adopt Leicester

approach to recording gully inventory and cleaning records

• Define and collate record of hot spots
• Identify appropriate way to store drainage

data e.g. GIS, Asset Management software system

Task: 2

Adopt a consistent method of prioritisation

• Using the Derby approach as a starting point
• Consistent method of evaluating the risk

associated with each site and;

• Prioritisation for investigation and potential

mitigation/treatment

Task: 3

Data collection methods

• Determine an appropriate specification

and/or method of collecting information about site that need investigation

• Method needs to incorporate inventory

collection, cleaning, condition assessment, proving and outlet

• Possible assessment of catchment area

Task: 4

Examining Potential Solutions

• Determine a process for the investigation

and appraisal for potential solutions including

• Enhanced maintenance regimes
• Gully emptying frequency
• Capacity

Task: 5

Business Case for Additional Investment

• Development of Business Case

Project Risks

• Availability of council staff resources to

undertake tasks

• Inability to obtain funding to address the issues

identified from investigations

• Duplication of effort with the Surface Water

Management Plans

• Issues about obtaining data from water

companies

4 Sharing: Communication Plan

Between ourselves & others with drainage projects (other element two winners) then .... with regional groups and stakeholders then .... Promulgation to National Audience (via Roads Liaison group/DfT, CSS etc ?)

Sharing: How

• Nottingham City Council has procured

P2.net, a web based project management system based on Prince2 methodology

• We are examining how appropriate

aspects of this could be made available externally. Presentations to regional groups

• Conferences
• Hosting visits from other authorities
• Providing information to other authorities

Tangible Outputs

• Case studies
• Lessons learnt
