Websites for drainage firms in Plymouth that name the Critical Drainage Area.

Plymouth City Council states that most of Plymouth is a Critical Drainage Area, which it describes as an Environment Agency definition for an area where the existing drainage system is considered to be at, or close to, capacity.

We build the emergency page, the unblocking page, a septic tank page and an area page for Cattedown, Mutley, Peverell and Plympton. The Valuation Office records 123,310 properties in Plymouth, 23.5 per cent of them built before 1919 and 30.0 per cent between 1945 and 1972. See it live before you pay a penny, live in 7 days.

The houses in Plymouth

The published Valuation Office stock table CTSOP4.1, stock at 31 March 2025, records 123,310 properties in Plymouth. 23.5 per cent were built before 1919 and 36.2 per cent before 1940. 30.0 per cent went up between 1945 and 1972, 20.0 per cent between 1973 and 1999 and 13.7 per cent since 2000.

Census 2021 table TS044 records 32.8 per cent of households terraced, 30.1 per cent semi detached and 11.4 per cent detached, with 16.2 per cent in purpose built flats and 7.5 per cent in converted flats, a combined 23.7 per cent. Table TS054 records 19.9 per cent renting from a private landlord or letting agency and 18.4 per cent renting socially. Plymouth is a unitary authority and the published row covers the city.

We would build the terraced inner city and the post war estates as separate pages, put the flats and managed buildings on their own, and give the septic tank work outside the city a page with its own questions.

Cattedown and Prince Rock

77.1 per cent built before 1919 (VOA CTSOP4.1, MSOA row).

A page on what a CCTV survey records and how the findings are reported.

Mutley and Lipson

77.0 per cent and 74.6 per cent built before 1919 (VOA CTSOP4.1, MSOA rows).

Separate contact routes for homeowners, landlords and agents.

Peverell

68.3 per cent built before 1919 and 23.9 per cent between the wars (VOA CTSOP4.1, MSOA row).

A written case study of completed work in Peverell.

Southway and Tamerton Foliot

71.3 per cent and 75.3 per cent built between 1945 and 1972 (VOA CTSOP4.1, MSOA rows).

Domestic unblocking and gully services described where you offer them.

Plympton Chaddlewood

80.9 per cent built between 1973 and 1999 (VOA CTSOP4.1, MSOA row).

A page on how you identify the cause of a blockage before quoting.

The rules that change a drainage job in Plymouth

Plymouth City Council states: "Most of Plymouth is a Critical Drainage Area, defined by the Environment Agency as an area where the existing drainage system is considered to be at, or close to, capacity." It also states that all new developments require a surface water drainage system designed to a 1 in 100 year design standard with an allowance for climate change, and that for single property developments not at risk from flooding from rivers or the sea the lead local flood authority has produced pre application standing advice on surface water drainage.

The transfer on 1 October 2011 covered qualifying private sewers and lateral drains connected to the public sewer system by 1 July 2011 (gov.uk, the private sewers transfer regulations). Responsibility for an individual pipe should be checked with South West Water.

South West Water states that a new development or an extension over or within three metres of a public sewer or lateral drain must be notified, that it must approve the proposal even where planning permission has already been granted, and that a customer declaration or a build over enquiry leads to a letter of consent.

We would explain how you check the Critical Drainage Area guidance, the build over route and the proposed work before confirming whether permission is needed.

The local field, 16 September 2026

Who you are up against in Plymouth

We counted the Google Maps results for drainage companies in Plymouth on 16 September 2026. The sample was 40 listings: 33 had a website and 7 had none. Seventeen describe themselves as a drainage service with a Plymouth address. Two are branch pages of national drainage groups, four are merchants or materials suppliers, and the rest are groundworkers, paving firms, construction companies, surveyors and plumbers.

That is one dated sample of one search. What we would do with it is give Cattedown, Mutley, Peverell, Southway and Plympton a page each, carrying the jobs you have finished in them.

Where a drainage firm in Plymouth gets to when they invest

Three Plymouth firms whose websites we opened and checked. One runs a Locations menu, nine named services and a Drain Wiki section, and another puts the Plymouth landline above the menu.

  • Drainblock Services Ltd

    It carries a page per area and reviews on the page. Quotes come through a form, and the phone number sits in the header.

  • Drain Care (South West) Ltd

    Built on Wix. It carries photographs of its own jobs and reviews on the page. It has no page per area. Quotes come through a form, and the phone number sits in the header.

All three keep the phone number in the header, all three carry reviews on the page, and one runs a page per area. Each one opened and checked 16 September 2026.

The Plymouth searches worth their own page

  • "blocked drain Plymouth"

    140 searches a month (OpenSEO keyword data, September 2026)

    The emergency page, with the number fixed to the screen and the areas you reach underneath.

    140 searches a month (OpenSEO keyword data, September 2026)

    Its own page for the booked job, with the access questions asked before anyone drives out.

    A page for the tank work, with the area you cover, the process and the booking route on it.

    no recorded monthly volume (OpenSEO keyword data, September 2026)

    The survey page is built regardless, with a still from the camera and a sample report.

  • "drain repairs Plymouth"

    no recorded monthly volume (OpenSEO keyword data, September 2026)

    Repairs and relining get a page, linked from the survey page where the fault is found.

What we would build for a Plymouth drainage firm

  • A home page naming Cattedown, Mutley, Lipson, Peverell, Southway and Plympton.
  • A blocked drain page built for the phone.
  • A drain unblocking page beside it for the booked job.
  • A septic tank page with the area covered, the process and the booking route.
  • A CCTV survey page with a still from the camera and a sample report.
  • A page on the Critical Drainage Area guidance and the South West Water build over route.
  • Area pages for Cattedown, Mutley, Peverell, Southway, Plympton and Devonport.
  • A quote tool that asks what is blocked, how urgent it is, house or business, and takes a photograph.

What every drainage site needs, whatever the town, is on our drainage companies page.

Drainage companies in Plymouth ask us

  • Is there anything about Plymouth a drainage site should say that others do not?

    Plymouth City Council says most of Plymouth is a Critical Drainage Area, which it describes as an Environment Agency definition for an area where the existing drainage system is at, or close to, capacity, and it sets out the surface water requirements for new development. The page would link to that guidance and explain the South West Water build over process separately.

  • We do septic tanks outside the city. Worth a page?

    OpenSEO recorded 30 monthly searches for septic tank emptying Plymouth in September 2026. If you offer that service, a page of its own can set out the area you cover, the process and the booking route. The volume describes searches for the phrase rather than the value of any job.

  • What did the Plymouth listings show?

    Of the 40 Google Maps listings returned on 16 September 2026, 17 were a drainage service with a Plymouth address, and every one of the ten firms on the recorded local search list is a drainage listing rather than a merchant or a plumber. We would build a page for each named service with photographs of your own completed work.
