Who approves a septic tank in Jamaica?

Your municipal corporation, which law firm DunnCox describes as the local building authority. The Building Act 2018 came into force on 15 January 2019 and requires permits for building work.

In Kingston and St Andrew, KSAMC wants permission for construction, demolition and "Additions /alterations and external repairs", and quotes "approximately four (4) weeks" for a single-family house. St James routes applications through its Roads and Works Department, on requirements dated 2008, so check they still apply.

We found no statement on whether replacing a pit alone, with no other building work, needs a permit. Ask before digging. The wider process is on building approval.

KSAMC's documents, from 2020, are the clearest we found:

• The drainage plan, with storm water and plumbing layout
• Septic tanks, absorption pit and soak away pit, along with sanitary drains and the final disposal point
• Details of the sewage disposal system, with an "engineering report where applicable"
• A minimum of four drawing sets

Manchester's Planning Department handles applications, but the pages we read list no drainage items, and Portmore's application page showed no text when we checked. Elsewhere, ask for the parish's own checklist.

KSAMC treats the Ministry of Health's Environmental Health Unit as a "Critical referral agency". Its Helpful Tips say both water and sewage have to be "to the satisfaction of" that unit and the National Water Commission (NWC). No plumber sign-off is named.

NWC says it "does not approve development projects", and that its legal power over water and sewerage proposals applies "only in Kingston and St. Andrew". Elsewhere it recommends.

We found no size or design rule and no setback distance for a house system, so we give none. Ask your parish health department before plans are drawn.

Probably not, as we read it, but confirm with NEPA. Under the 2013 wastewater regulations, regulation 5(2), a licence "shall not be required" for discharge of domestic wastewater treated by absorption or soak away pits or other prescribed systems, if done in accordance with applicable law.

NEPA's brochure puts "Housing projects of 10 houses or more" and "Subdivisions of 10 lots or more" among prescribed categories, and all of Jamaica is a prescribed area. A single house did not appear in the portion we could read.

It can become a public health matter, whoever built the system. The Public Health (Nuisance) Regulations 1995 say "No person shall cause or permit a nuisance on any premises owned or occupied by him", and the schedule includes sewage discharged onto land or into a watercourse. A Medical Officer (Health) or Public Health Inspector may act.

So the parish health department is the right place for a neighbour's overflow, or advice on your own. If yours has overflowed, start with the signs of a full pit.

Regulation 28 is short: "Domestic septage and industrial septage shall be disposed of in a treatment plant approved by the Authority." The definition of septage covers what comes out of a septic tank, cesspool or portable toilet.

We found no licence scheme for people who empty pits, and no public list of approved sites. NWC's fee list has a dumping charge but does not say which sites take loads.

Ask which plant the load goes to, and get the answer in writing with the price.

Then a septic tank may not be the end of the matter. NWC's wastewater page, citing section 12 of its Act, says it "may require the owner of any premises within the Service Area to connect". The occupier applies within three months of notice, otherwise NWC may connect at the owner's cost.

Under 1985 regulations, being within "100 yards (91.4 metres)" of a line can bring a sewerage charge too, "whether or not the premises is actually connected". A building application that uses the sewer needs a letter from NWC. Roof and yard water stays out: "Storm water shouldn't flow into wastewater sewers".

An old pit left behind after connecting is a job for a qualified contractor and the health department. Do not fill or open it yourself.

A qualified contractor, working to the approved drawings. Tanks and pits can hold deadly gas once in use, so repairs and alterations to an existing one are never owner jobs, and nobody enters or leans into one. A person overcome at a pit is not saved by following them: stay out and call 110.

We could not confirm any licence or public register for plumbers in Jamaica, so "licensed" on a business card proves little. Ask who prepared the drawings and who will deal with the inspection. Our notes on hiring a plumber list more questions, and cesspool, septic or soakaway explains what you are being quoted for.
