Septic installation in Warsaw and Douro-Dummer

Septic installation in Douro-Dummer means stony moraine ground and, on four lakes, a Township inspection program that will come back to your system. Properties on Stony, Clear, Katchewanooka and Dummer Lake are inspected zone by zone, and the Building Department checks a test pit before it issues any permit. Douro-Dummer was already running its own sewage permits before Peterborough Public Health left the program in 2024.

New septic installation

Building a house, cottage or shop? You get a complete system sized for the bedrooms and fixtures you are actually putting in, designed to pass the inspection the first time.

  • ✓System design and the Part 8 permit application, handled by us
  • ✓Tank, distribution box and leaching bed installed
  • ✓Conventional bed, raised or filter bed, or tertiary unit, whichever the site needs
  • ✓All excavation, imported fill and backfill included
  • ✓Final grading and site restoration

Septic replacement

Old bed failing? Sewage surfacing, slow drains, a health unit order, or a system that predates the property? You get the old tank out and a new system to current Ontario Building Code, with the inspection coordinated for you.

  • ✓Old tank pumped, removed and disposed of
  • ✓Failed drain field, weeping bed or leaching bed excavated
  • ✓New system to current Part 8 code
  • ✓Health unit or building department inspections coordinated
  • ✓Site restored clean when we leave

We install conventional drain fields (weeping beds, leaching beds, tile beds), raised and filter beds where bedrock or the water table is close, and tertiary treatment units such as Waterloo Biofilter and Ecoflo where the lot or the shoreline calls for one.

We install and replace. We do not do pump-outs or minor repairs. If you only need a tank pumped or a baffle fixed, we will point you to someone who does that. If your system has failed or you are building new, we are the right call.

Septic in Warsaw and Douro-Dummer: what changes here

Who issues the permit

The Township of Douro-Dummer issues a separate sewage system permit for every new or replacement system, through its own Cloudpermit workspace. The design starts in the ground: a test pit dug to at least 1.5 metres, which the Building Department inspects. The zoning by-law then fixes the layout, with every sewage system at least 30 metres from the high water mark and 3 metres from any street or private road. We dig the pit, prepare the application and meet the inspector.

The ground you are on

The county soil survey maps its largest area of Dummer soils in Dummer and Belmont townships, on the very stony calcareous till of the Dummer moraine, with strongly sloping, complex ground and, in a few spots, only a thin layer over limestone. The Rockcroft soils beside them drain imperfectly, with bedrock 30 to 60 centimetres down. A bed here is often raised, and the stone comes out before it goes in.

The rule that shapes the design

Douro-Dummer's Discretionary Sewage System Maintenance Inspection Program covers every property abutting Dummer Lake, also called White Lake, Stony Lake, Clear Lake and Katchewanooka Lake, ten zones in turn under Building By-law 2024-31. A system new or fully replaced within the previous ten years is exempt when its zone comes up, and a failed inspection gets 30 days for corrective work before an Order to Comply. A new system resets that ten-year clock.

Septic installation in Warsaw and Douro-Dummer: your questions answered

Who issues the septic permit in Douro-Dummer?

The Township of Douro-Dummer Building Department, through Cloudpermit. It handled sewage permits before Peterborough Public Health's 2024 exit and still does. We prepare the application for you.

Is there a source protection inspection as well?

Yes. Properties Otonabee Conservation identified in the Trent source protection vulnerable areas get mandatory maintenance inspections. The Township completed that round in 2025, and the next one is due in 2030.

What does the lake program inspector need from me?

The Township asks owners to uncover the tank lids and not to have the tank emptied beforehand, so the inspector sees the system as it really runs. A system we install leaves the lids easy to reach.

Do you handle the septic permit?

Yes. We arrange the design and file the Part 8 sewage system permit with whichever office covers your property, a municipal building department or the health unit, and we book every inspection.

How much does a new septic system cost?

A conventional system for a typical home in Central Ontario runs about $15,000 to $30,000. Raised beds, tertiary units and difficult access push it higher. You get a written price after the site visit.

How long does an installation take?

Three to five days on site for most systems. Add the permit lead time in front of that, which we manage and keep you posted on.

How do I know my septic system is failing?

Sewage surfacing or a wet, spongy patch over the bed, slow drains through the whole house, gurgling, sewage smell outside, or an unusually green strip of lawn over the bed. If you see any of these, call. If it needs replacing we will tell you straight, and if it only needs a repair we will send you to someone who does repairs.

Do you install raised beds and tertiary systems?

Yes. Where bedrock, a high water table or a small lot rules out a conventional bed, we install raised and filter beds and tertiary treatment units such as Waterloo Biofilter and Ecoflo.

Can you install in winter?

Often, depending on frost depth and access. Frozen ground costs a bit more. If your system has failed and cannot wait for spring, call and we will tell you whether your site works in winter.
