Planning drainage for new housing developments

New housing developments need a drainage strategy: surface water (soakaways, attenuation or main drain) and foul (connection to sewer). Planning and adoption requirements drive the design. We deliver the groundworks and drainage to the approved design.

Planning drainage for new housing developments usually becomes urgent when recurring symptoms begin affecting programme confidence, compliance, or delivery reliability.

When you might need this

Teams usually investigate planning drainage for new housing developments when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.

What often triggers action

The symptoms below are the most common triggers we see before diagnosis and repair planning.

• Drainage strategy in planning
• Surface water and foul design
• Adoption by water company
• S104 or S38 agreement
• We build to the design

What to expect from the work

We work from your drainage engineer's design and adoption agreement. We deliver the drainage infrastructure to programme.

How this gets resolved

We install drainage to design with testing and handover for adoption. We provide as-built documentation.

Cost and complexity factors

Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.

How we work through the job

We keep delivery structured so scope, sequencing, and sign-off remain clear.

1. Step 1: Initial assessment

   What this step delivers: Root cause and scope are confirmed.

2. Step 2: Method planning

   What this step delivers: Practical repair strategy is agreed.

3. Step 3: Delivery and verification

   What this step delivers: Work is completed and validated.
