GROUNDWORKS & DRAINAGE 35 The pressure is on
T-T Pumps’ Jon Whittingham discusses the rise in use of package pumping stations as sites using gravity drainage for waste or surface water become rarer – and the key points that architects should consider.

hen it comes to specifying a solution for the removal of waste and surface water from
a development, package pumping stations are an increasingly popular choice. With so many options available in today’s market, including a wide range of chamber sizes and pump models that cater to different applications, they are a versatile solution that can be implemented on diverse sites. Package pump stations can be procured within short timescales to fi t with tight project deadlines and benefi t from a ready- to-use design that permits quick installation below ground in comparison to bespoke methods such as pre-formed concrete rings. Conventionally, systems consist of a pre- formed chamber (traditionally made from glass reinforced plastic). Chambers are now more commonly constructed in materials like polyethylene due to production repeatability and lower environmental impact), pre-assembled internal pipework and valve assemblies – delivered to site

ready for immediate installation. The increasing need for pumped drainage solutions is also driving package pumping station use. As new infrastructure is developed across the UK, the number of sites available with topography that facilitates gravity drainage is dwindling, necessitating an increased use of pumped drainage systems. These systems play a crucial role as part of the infrastructure they serve, but informed selection is essential to effective waste management that protects buildings and the environment from spills.

Approved Document H details essential design features for drainage and waste disposal systems. This includes key aspects for pumping stations, such as provisions for 24 hours of storage within the pump station chamber, in the event of a system or power failure.
