YOUR NEW DRAIN INSTALLATION ENQUIRY
Plan your new drain installation enquiry
Adding an extension, changing a drainage route or planning new rainwater collection? Enquire about assessment and installation with the water type, destination and approvals established before construction.
What to include in your enquiry
- The planned work, property postcode and whether it involves foul water or rainwater
- Existing drawings, known routes/outlet and approval status
- Access, shared land and whether you need design, installation or both
What should the quote cover?
Compare the designed route, excavation and chambers, intended outlet, tests, approvals and reinstatement. Identify fees and design/application work separately from installation; no contractor quote grants a sewer connection.
Can a new drain be connected to the nearest pipe?
Only after its use, ownership, capacity and permission have been established. Proximity does not make it an approved outlet. A foul drain and a rainwater route need appropriate destinations and separate checks.
Address, access and responsibility checks
Haverhill, Kedington and Withersfield are in West Suffolk; nearby Sturmer and the Bumpsteads use Braintree district routes; Castle Camps, Shudy Camps and Horseheath are in South Cambridgeshire. Council planning/building-control decisions and Anglian Water sewer decisions are separate. Confirm the actual address and chosen building-control body.
- Check the full-postcode authority and planning/property restrictions
- Identify the drainage owner and any land or shared-access permission
- Agree design and approval responsibilities before site work

Define the new drainage job
Explain what is changing: new facilities, an extension, relocation of private pipework or rainwater collection. State whether you already have a design and want installation, or first need route and outlet advice. Repairing a short damaged section is a different starting point from designing a new run.
For an occupied property, give the facilities that must remain usable and access restrictions. Ask how temporary arrangements, excavation protection and the handover between designer and installer will be agreed.
Useful next steps
Foul water and rainwater need suitable destinations
Identify what each proposed pipe carries and where it will discharge. Existing covers and drawings are clues to investigate, not permission to use a pipe. Ask for confirmation of the proposed destination and how incorrect connections will be avoided. An infiltration proposal needs its own site assessment.

Locate existing routes and buried assets
Ask what records and site investigation are needed before the route is fixed. Existing drainage may include unmapped or shared pipework. A CCTV survey can inspect accessible runs, while locating or other checks may be needed to establish position for the design.
Give known utilities, structures and restricted areas. Do not dig trial holes or disturb covers to establish the route yourself. Agree who obtains the evidence, records uncertainty and checks conditions before work proceeds.
Useful next steps
Council approval follows the actual address
Confirm planning conditions, building-regulation requirements and any heritage/property controls separately. West Suffolk’s building-control route applies to its addresses; Braintree has a separate council inspection route, and South Cambridgeshire participates in 3C Building Control. Agree the project’s inspection stages before covering work. A planning decision and a building-control completion record do different jobs.

Sewer connections need their own application
Where Anglian Water’s public sewer is the proposed destination, use its connection application process. It assesses the proposal; the applicant appoints a contractor for the work and follows the applicable inspection requirements. Establish the connection location, method and drawings first. Ask the operator about your actual proposal and confirm fees separately from the installation quote.
Access, excavation and reinstatement
The A1307, A1017 and A143 identify approaches to Haverhill, but do not establish safe final access for the job. Describe the gate width, occupied spaces, shared passage and available working area. Ask how equipment, removed material and deliveries will be managed.
Agree protection of buildings, existing services and neighbouring surfaces, plus safe access while the trench is open. Distinguish private-land work from anything affecting a highway or third-party land; the quote should identify permissions still needed.
Installation quote and commissioning checklist
Request the same scope from each business so the comparison covers a finished, usable drainage route.
- Design/drawings, route, water type and intended outlet
- Pipework, chambers/access points and any pumping or specialist components actually proposed
- Applications, fees, permissions and inspection arrangements: who is responsible
- Excavation protection, removed material and agreed surface finish
- Testing, as-built plan, completion/inspection records and maintenance information
Handover and future access
Keep the final route and access-point record, inspection evidence and component instructions. Ask how the installation will be checked before surfaces are restored, which approvals remain outstanding and who closes them. If the design changes on site, have the variation explained and recorded. Sending this enquiry is the start of discussing scope, not permission or a work booking.
