1. What is meant by groundworks?

Groundworks refers to all work carried out to prepare sub-surfaces before construction begins. This includes excavation, trenching, foundations, drainage, and installing utilities (such as electricity, gas, water and sewage).

2. What is a drainage system?

In construction, a drainage system removes surface water, foul water, or both from a site. It can include pipes, manholes, gullies, and channels connected to the mains or soakaways.

3. What is foul water drainage?

Foul water drainage carries wastewater from toilets, sinks, baths, showers, dishwashers, and washing machines to a public sewer or private treatment system. This system is separate from surface water drainage to prevent contamination. Foul drainage typically includes soil stacks, underground pipework, and inspection chambers.

4. What is a sustainable drainage system?

A sustainable drainage system (SuDS) is designed to manage surface water runoff in a way that mimics natural drainage. It slows water flow, encourages infiltration, and improves water quality. SuDS features include permeable paving, swales, filter drains, detention basins, and soakaways. These systems reduce flood risk, limit pressure on public sewers, and support compliance with planning requirements.

5. What is surface water drainage?

Surface water drainage collects rainwater from roofs, roads, and paved areas. It directs water to specialised soakaways, storm drains, or attenuation systems to prevent flooding.
