At Drainage Design, we work with developers, architects, and planning consultants in Oldham and across the UK to secure planning approval by producing drainage designs that meet both local authority requirements and national SuDS guidance.

Each design is tailored to the specific site, ensuring that surface water run-off and foul water disposal are managed efficiently, sustainably, and in full compliance with regulatory standards.

By combining engineering expertise with local insight, Drainage Design help ensure a smooth transition from planning through to construction.

Why Is Drainage Design Important for Developments in Oldham?

For any new development in Oldham, a drainage design is a key document that outlines how the site will manage both foul and surface water. Planning officers use it to confirm that the proposal will not increase flood risk, overload sewer networks, or negatively impact surrounding watercourses.

Our designs include detailed run-off calculations, proposed system layouts, and water flow control measures in Oldham, providing authorities with confidence in your application and reducing the risk of costly delays.

Which Types of Projects Across Oldham Require a Formal Drainage Design?

We prepare drainage designs in Oldham for a wide range of developments where planning policy requires effective surface and foul water management, including:

• Housing estates – New residential schemes creating significant impermeable areas.
• Retail parks – Commercial sites with large paved areas and high surface run-off.
• Schools – Educational facilities requiring safe, compliant drainage systems.
• Healthcare facilities – Hospitals, clinics, and care homes with complex drainage needs.
• Industrial units – Factories, warehouses, and processing facilities with substantial run-off.
• Small schemes in sensitive locations – Single plot conversions or extensions in flood-prone areas or near sensitive drainage networks.

How Much Does Professional Drainage Design Cost in or Around Oldham?

The cost of a professional drainage design in Oldham ranges from £500 to £3,000+, depending on site size, project stage, and the complexity of the design.

Costs are influenced by factors such as the size and layout of the site, the level of detail needed in calculations and drawings, the requirement for additional surveys or testing, and the amount of liaison needed with planning authorities or water companies.

How Do Engineers in Oldham Ensure Designs Meet Planning and SuDS Requirements?

Our drainage design team is well-versed in the SuDS guidelines and planning policies that apply to Oldham, and we ensure every drainage design meets both national standards and local requirements.

We address water quantity, water quality, biodiversity enhancements, and climate change allowances. By liaising early with Lead Local Flood Authorities, the Environment Agency, and water companies in Oldham, we ensure the design is both compliant and practical to deliver.

Can Drainage Designs in Oldham Cover Both Foul and Surface Water Management?

Most developments in Oldham require their drainage design to incorporate both foul and surface water systems. We produce integrated designs showing how foul water will be discharged to the sewer network or treated on-site, alongside surface water systems that manage run-off and protect downstream infrastructure.

This combined approach reassures planning authorities in Oldham that water management has been considered comprehensively.

What Data and Surveys Are Needed Before Preparing a Drainage Design in Oldham?

Before preparing a drainage design for a site in Oldham, we collect accurate data, including topographical surveys, site investigation results, utilities mapping, and relevant flood risk information.

If necessary, we can arrange CCTV drain surveys, infiltration testing, or flow monitoring. This evidence-led process ensures the design in Oldham reflects actual site conditions, minimising the need for later revisions.

Do Consultants in Oldham Liaise With Local Authorities During the Approval Process?

As part of our drainage design service in Oldham, we act as your point of contact with planning officers, LLFAs, and water companies.

This enables us to address queries promptly, secure timely approvals, and keep your application in Oldham progressing. We also offer post-approval support to ensure drainage-related conditions are satisfied without delaying construction.
