Drainage System Tenders and Contracts

Drainage system tenders cover the design, installation and monitoring of sustainable drainage systems, such as rain gardens, swales and attenuation basins, together with land drainage systems that manage water on agricultural, amenity and highway land.

A sustainable drainage system, or SuDS, manages surface water using features like permeable paving, swales and attenuation basins rather than piping it straight into the sewer network. Public sector SuDS schemes are built at schools, parks and street-end sites to reduce local flood risk.

Stotles brings together drainage system tenders and contracts from 100+ portals into one search, so you do not have to check each portal separately, and you can set alerts for new opportunities across the UK and Ireland.

If you want to search the government portals directly, Find a Tender carries higher-value contracts across the UK and Contracts Finder carries lower-value contracts in England. Public Contracts Scotland, Sell2Wales and eTendersNI cover Scotland, Wales and Northern Ireland, Ireland's eTenders covers Irish public bodies, and many councils, NHS bodies and housing associations publish on their own e-tendering portals such as ProContract. SuDS schemes are often let as small civil or landscape works packages, and drainage surveys and jetting are called off from highways and housing repairs frameworks.

Drainage system tenders are scored on price, design and technical approach, programme, environmental management and the contractor's record on similar schemes. SuDS schemes also score long-term maintenance and planting quality.

Drainage works bring duties under the Construction (Design and Management) Regulations 2015, and work on highways needs street works accreditation. Tenders usually set minimum insurance cover, check financial standing and ask for evidence of similar schemes at selection stage. Under the Procurement Act 2023, suppliers can be excluded for certain criminal convictions, insolvency or failure to pay tax.

Councils are common buyers, commissioning drainage system schemes for housing, parks, highways and school sites. Other public sector landowners also run their own land drainage and SuDS contracts.

Read surface water management plans, flood risk strategies, housing repairs programmes and drainage survey schedules, which show work coming due ahead of a notice. On Stotles you can track those signals and the councils and housing associations behind them, then follow a notice from pre-tender through to award.

Drainage notices carry 45232452 (Drainage works), 45232454 (Rain-water basin construction work), 90470000 (Sewer cleaning services) and 90400000 (Sewage services). SuDS schemes often add 45112710 (Landscaping work for green areas).
