What makes village house drainage unique
Three structural differences from a flat shape every village-house call we run:
1. Septic tank (化糞池) on the property
Most NT village houses outside designated DSD sewer catchments rely on an individual septic tank buried in the garden or under the entrance slab. Sewage flows in, solids settle, supernatant overflows to a soakaway pit. Over 3-7 years (depending on household size and detergent load) the sludge layer rises until it reaches the outflow — at which point the toilet, kitchen and ground-floor floor drain all slow simultaneously. This is not a blockage you can auger. It needs a licensed waste-collector pump-out. We diagnose, you confirm, we coordinate the pump-out appointment with a licensed contractor.
2. Individual drainage — no shared stack
Flats share a vertical waste stack with units above and below; village houses do not. That means problems stay yours — nobody else can cause your blockage, and you cannot escalate to the OC. The upside: when we clear it, it is cleared, no upstream surprises. The downside: there is no management company to split the bill with.
3. No body corporate, no OC
If your village is part of a Heung Yee Kuk co-op or has a village committee, internal politics may matter for shared driveways and surface drainage — but inside your property line, no management company exists. The Lands Department and Buildings Department only get involved for structural and unauthorised-build (UBW) issues. Drains are on you.
Common village house drain problems
When to call DrainFix vs. when to call someone else
Call a licensed waste-collector (we coordinate) if: the septic tank is full and needs pumping. We do not pump — we have a working relationship with several licensed NT collectors and we facilitate the appointment. They invoice you directly.
Call Buildings Department if: there is a structural drain failure (UBW issue, building defect, neighbour's UBW affecting your drainage). Not our scope.
Call DSD (渠務署) if: the public roadside drain or village stormwater channel is blocked. Free service for genuine public infrastructure.
Tenant vs landlord — who pays in a village house?
Village houses have no OC, so the rental contract is the only reference. General HK norms (not legal advice):
- Tenant: blockages caused by use — hair, wet wipes, foreign objects, kitchen grease.
- Landlord (owner): septic tank pump-out (capital infrastructure), root intrusion, drain pipe failure or collapse, septic soakaway works.
- Negotiate: first call within first 30 days of tenancy — often a pre-existing condition, landlord usually picks up.

Frequently asked questions
- Do I have a septic tank or am I on mains drainage?
- Most NT village houses outside DSD sewer catchments are on individual septic tanks. Check your title deed or ask Lands Department. We can also tell on-site within 10 minutes by looking at the access lid.
- How often should the septic tank be pumped?
- Industry rule of thumb: every 3-7 years for a 2-4 person household. Heavy detergent + frequent washing-machine loads shortens the interval. If you have never pumped it and the house is 10+ years old, schedule one regardless.
- Can you reach my Sai Kung village?
- Yes, but be honest — 2-3 hours travel each way is realistic for Pak Sha O, Tai Long Wan, remote Sai Kung peninsula. 120-min typical does not apply that far out. We confirm ETA in writing before dispatch.
- Is there a travel surcharge?
- Yes, disclosed up front. +HKD 100-300 typical depending on distance. Full quote (service + travel) on WhatsApp before we leave. No on-site surprises.
- Who pays — tenant or landlord?
- Use-caused blockages: tenant. Septic pump-out, root intrusion, pipe failure: landlord. See our tenant-vs-landlord guide for the full breakdown and WhatsApp templates.
