Drainage & Attenuation - Stringfellow

What is Drainage & Attenuation?

Drainage refers to the system or process of removing excess water or liquid from an area, typically from the surface of the ground, buildings, or infrastructure. Proper drainage is crucial to prevent water accumulation, which can lead to issues such as flooding, soil erosion, waterlogging, and damage to structures.

Attenuation is the process of reducing or slowing down the flow of water. Attenuation systems are designed to manage the rate at which water is discharged into watercourses or drainage systems, preventing issues such as flooding and erosion.

Case study

Project: Glossop North End Football Club

Client: Building Projects Group

Location: High Peak, Derbyshire

Project value: £240k

Contract period: 9 months

Project Overview:

A complete groundworks package to the clubhouse building, car park, section 184 highways entrance, and drainage & attenuation system for 3G pitch

Background:

This was previously a greenfield site, with a challenging site due to the ground conditions being extremely boggy. This was mainly due to the thin layer of soil directly on top of rock giving no drainage. The project required the utmost sensitivity to local residents.

The existing clubhouse was dated with a lack of facilities and parking. The pitch was not level, on a slope and water logged due to poor drainage and current access from the highways was not suitable/dangerous location for the volume of traffic to the club.

Our goal was to provide more useable, modern facilities for players and visitors along with an all weather 3G pitch with adequate parking and safe access from highways.

Our clients main concerns were the wet ground conditions, especially given the time of year (Jan – Jan), The finishing concrete was completed in December / January – and we achieved a high quality brushed finish

livestock management, residential interest, traffic management and delivering on time and in budget as it was grant funded. Stringfellows had worked with the client on previous projects which eliminated concerns, as they had already experienced our time management, work ethic and quality of work.

Scope of work;

Attenuation system – 900mm diameter pipework together with 2.5m diameter sumped chambers up to 3m deep including flow control gates were installed throughout the site to suit with the large volume of surface water from the new 3G pitch, car parking areas and rain water systems.

Drainage – installation of a complete foul water treatment plant along with the installation of a large interceptor tank to accommodate with any pollution from the car parking areas. These systems fed through into the attenuation system.

Section 184 – To accommodate the increased volume of anticipated traffic to the new club, a new access road was installed onto the existing highway. This was challenging due to the topographical nature of the site and the highway as it was elevated from site. Traffic management systems were used along with footpath diversions to enable the works.

Car park- to be reduced to achieve the correct ground levels. This was predominantly hard rock and so over sized excavators with ripper attachments and hydraulic breakers were used.

Foundations – the natural strata changed where the foundations of the club house was cited therefore deep excavations were required over 3m deep

Our client was impressed by how we managed the surface water whilst carrying out the deep excavations for the attenuation systems. Careful management of access on and off the site for materials and other contractors whilst installing the new road in and onto the highways

“Stringfellows ensured that work did not grind to a holt on site during the winter months by continuously maintaining access through the site for deliveries /trades despite boggy conditions. This proved to be invaluable for us to achieve deadlines and a priority we had not foreseen. Something we would give as a word of advice to others considering similar projects. Its important you have a team like Stringfellows who are willing to support in unforeseen / unexpected situations”
