Defra guidance, last revised 28 September 2011, and the authoritative plain-English account of the private sewers transfer that most drainage guides get vague about. Paragraph 2: on 1 OCTOBER 2011 all privately owned sewers and lateral drains which communicate with (drain to) an existing public sewer as at 1 JULY 2011 became the responsibility of the sewerage undertaker. Paragraph 3: private pumping stations on transferred pipework transfer between 1 October 2011 and 1 OCTOBER 2016, with any not transferred earlier transferring on that date; pipework upstream of a pumping station transferred on 1 October 2011. Definitions (from s.219 Water Industry Act 1991): a SEWER is a drain shared or used by more than one property; a LATERAL DRAIN serves a single property but lies outside its curtilage, under another property or the street. Both definitions include manholes, ventilating shafts, access chambers, pumps and valves. Paragraph 48: an occupier can only commission work within the private drain and has no authority to commission work in a public sewer or lateral drain without first contacting the water and sewerage company. Paragraph 49: interfering with a public sewer or public lateral drain without consent may lead to prosecution.

Drinking Water Inspectorate
The regulator's account of lead pipework, useful for any period-property or plumbing note. States that before 1970 lead pipework was commonly used to connect properties to the mains, that its use has since been banned, and that a home built before 1970 may have lead pipes while one built after 1970 is unlikely to. Gives a homeowner identification test at the internal stop tap: unpainted lead appears dull grey, often with a swollen joint next to the tap, and is soft enough that a gentle scrape with a coin shows shiny silver metal beneath, with disposable gloves worn and dust not inhaled; contrasts copper as bright, hard and dull brown, iron as dark, very hard and possibly rusty, and plastic as typically blue, or grey or black if older. Explains that lead dissolves while water stands in the pipe, with concentration depending on standing time, pipe condition, temperature (more dissolves in summer and autumn) and water hardness, since harder water forms a protective scale. Notes that water companies dose with orthophosphate where a risk exists, and that a less common cause is the illegal use of lead-based solder on copper pipe, lead solder remaining permitted only in closed central heating systems. Warns lead accumulates in the body, with infants including unborn babies and children most at risk of effects on mental development, and adults at risk of kidney, heart and circulatory harm.

Table 1.1 sets minimum intermittent extract rates: kitchen with a cooker hood extracting outside 30 l/s, kitchen without one 60 l/s, utility room 30 l/s, bathroom 15 l/s, sanitary accommodation 6 l/s. Extract terminals and fans other than cooker hoods should be as high as practicable and no more than 400mm below the ceiling; a cooker hood should sit between 650mm and 750mm above the hob if the manufacturer gives no figure. Table 1.7 requires background ventilators of at least 8000mm2 equivalent area in habitable rooms and kitchens for a dwelling, 10,000mm2 for a single-storey dwelling. Background ventilators should be at least 1700mm above floor level and at least 500mm from a fan in the same room. On replacement windows, paragraph 3.14 says new windows must carry background ventilators no smaller than the originals, and paragraph 3.15 gives the fallback minimums where the old size is unknown: 8000mm2 habitable rooms, 8000mm2 kitchen, 4000mm2 bathroom. Paragraph 3.32 confirms that replacing an extractor fan or cooker hood on existing cabling is not notifiable.

The statutory source for soakaway design and the discharge hierarchy every garden drainage note should state. Requirement H3(3) lists the order of priority for rainwater discharge: (a) an adequate soakaway or other adequate infiltration system, or where not reasonably practicable (b) a watercourse, or where not reasonably practicable (c) a sewer. Paragraph 3.25 bars infiltration devices within 5 metres of a building or road, in ground where the water table reaches the bottom of the device at any time of year, too close to other drainage fields or soakaways, or where contamination could pollute groundwater. Paragraph 3.26: soakaways serving less than 100 square metres are generally square or circular pits filled with rubble or lined with dry-jointed masonry or perforated ring units. Paragraph 3.27: design to a return period of once in ten years, and for small soakaways serving 25 square metres or less a design rainfall of 10mm in 5 minutes may be assumed as the worst case. Paragraph 3.28 requires percolation tests to derive the infiltration rate, and paragraph 3.30 sends larger soakaways to BS EN 752-4 or BRE Digest 365 Soakaway design. Paragraphs 2.10 to 2.12 cover pervious paving over a granular storage reservoir and warn against its use where sediment or oil spillage would block the pores. For foul drainage, paragraph 2.33 sets a minimum 75mm internal diameter, or 100mm for a WC, and Table 6 gives minimum gradients of 1 in 40 for 75mm and 100mm at peak flows under 1 litre per second.

SI 2011/1566 regulation 3, the legal instrument behind the private sewers transfer. It requires the Secretary of State to make a main scheme for the adoption of private sewers and private lateral drains by every sewerage undertaker whose area is wholly or mainly in England, with the Welsh Ministers doing the same for Wales. The vesting date for private sewers and lateral drains (excluding pumping stations) is 1st October 2011; pumping stations vest no later than 1st October 2016. The main scheme catches pipework situated in the undertaker's area which immediately before 1st July 2011 communicated with a public sewer (or, for a lateral drain, with a public sewer vested in that undertaker), excluding exempt sewers and those already subject to a declaration. This is the citation to use instead of a vague 'since 2011' or a bare 'Water Industry Act 1991 (amended)'.

The statutory duty behind 'the water company has to deal with it'. Section 94(1) requires every sewerage undertaker to provide, improve and extend such a system of public sewers, and so to cleanse and maintain those sewers AND ANY LATERAL DRAINS WHICH BELONG TO OR VEST IN THE UNDERTAKER, as to ensure that its area is and continues to be effectually drained, and to make provision for emptying those sewers and dealing with their contents at sewage disposal works. IMPORTANT LIMIT for consumer guidance: section 94(3) makes the duty enforceable by the Secretary of State, or by the Authority (Ofwat) with the Secretary of State's consent or general authorisation - it is not a duty a householder enforces directly, so wording like 'they are legally obliged to attend' overstates it.

Article 4(1) of the retained Construction Products Regulation requires a manufacturer to draw up a declaration of performance when a product covered by a designated standard, or conforming to a UK Technical Assessment, is placed on the market. Article 4(2) makes the declaration the only permitted route for stating performance against essential characteristics, so a performance claim outside the declaration is not valid. Article 4(3) provides that by drawing up the declaration the manufacturer assumes responsibility for the product's conformity with the declared performance, and that in the absence of objective indications to the contrary the declaration is presumed accurate and reliable. The words designated standard and UK Technical Assessment were substituted for harmonised standard and European Technical Assessment on 31 December 2020 by the Construction Products (Amendment etc) (EU Exit) Regulations 2019 (S.I. 2019/465), Schedule 1 paragraph 6.

Installing a new WC, as opposed to replacing one, therefore stays notifiable, and so does any replacement that touches underground drainage or uses more water.

SCOTLAND, latest revised version with no outstanding effects, and several of these contradict England. Type 20 makes a door, window or rooflight warrant-exempt EVEN WHERE THE FRAME IS REPLACED, so a Scottish window replacement needs no building warrant and no FENSA or Certass notification, unlike England where replacing a window is notifiable building work; it must still meet the regulations, including the 1.4 W/m2K or WER Band B standard. Type 19 exempts open raised external decking unless it is at a height of more than 1.2 metres. Type 21 exempts a paved area or hardstanding unless it exceeds 200 SQUARE METRES or forms part of a required access, a far more generous threshold than England's 5 square metre front garden rule. Type 22 exempts extra-low voltage electrical installations not exceeding 50 volts AC or 120 volts DC. Type 24 exempts like-for-like replacement of fittings including sanitary facilities, rainwater gutters and downpipes, solid fuel appliances, electrical fixtures, ventilation fans and kitchen fitments, but expressly NOT doors, windows or rooflights, nor oil or gas fired boilers. Type 25 exempts like-for-like replacement of flooring, lining, cladding, covering or rendering internally or externally.
