Below Ground Drainage Design

Installation of a new drainage system – or alterations to an existing site – must comply with Building Regulations as assessed by the local planning department.

Foul water systems relate to drainage from bathrooms, kitchens, car washing areas, utility rooms and similar while surface water drainage systems handle run off from rainwater and both are subject to regulations.

The construction of a below ground drainage system can be divided into several main phases. Firstly, it is necessary to decide the size and the number of all the components that are required in order to design the drainage system (pipes, bundles), followed by arranging transport and handling of the selected elements.

The next phases relate to the excavation of the area identified for the system. It is vital to take necessary precautions against trench collapse and not open trenches too far in advance of pipe laying. Consequently, the pipes can be laid in the ground with appropriate protection in order to avoid any damage caused by pressure and ground movement.

A drainage system’s capacity is determined by the diameter and gradient of the selected pipework along with the calculation of flow rates of water that will be expected to pass through.

The Syntegra team’s expertise in the design, selection and layout of such features enables us to deliver solutions that are sustainable, cost effective and meet with the required local and national standards.

If the development is on a previously developed ‘brownfield’ site, the strategy will seek to utilise the existing discharge disposal arrangement to watercourses, soakaways or public sewers.

Syntegra has expertise in managing flood risk, below ground drainage design, highways design, transportation, foul sewage and utilities assessment, geotechnics and land quality to inform critical decisions on infrastructure design.

Securing appropriate drainage facilities is an illustration of the importance of getting infrastructure right to ensure a site works seamlessly for all parties and provides ‘best value’ engineering.
