This page is a menu of options, not a plan. It walks through the choices the new council faces on water, sewers and stormwater. They are how fast rates rise, whether sewage capacity is built ahead of growth or growth waits for it, lead pipes, overflows to the Thames, how the stormwater charge is set, help for low-income households, and the Province's new water corporation law. For each one it gives the strongest evidence for and against, what it cost where it was tried, and the London-scale math, shown in full or plainly marked as not derivable. It recommends nothing.

One structural fact shapes everything here. Water and sewer run on their own money. The water bill, not the property tax, pays for the pipes, the pumping stations and London's five sewage treatment plants. London doesn't treat its own drinking water. It buys it wholesale from two regional systems, now branded Huron Erie Water, and holds a built-in majority on the Lake Huron board. So the levers in this file are the rate, the capital plan and the City's seats on those boards.

Research was completed November 3, 2026. Every claim links to a source, and figures we worked out ourselves are marked as derived. The council that takes office November 15, 2026 decides these questions, starting with the 2027 budget update.

READ EVERY NUMBER HERE WITH THIS

The City's average home bill for water, sewer and stormwater, $1,333 in 2026 and $1,399 in 2027 at 200 m³ a year, is the number every option here is measured against.

Councillors Franke and McAlister moved it and voted for it. Mayor Morgan and Councillors Peloza, Van Meerbergen and Stevenson voted against, and it failed 2 to 4. The committee then received the consultants' plan 6 to 0. On March 31 council approved the item without the report-back, 14 to 0 as part of the committee's report, and no member moved to restore it.

OPTION 1 OF 7

Steady full-cost rates, or smoothed increases

Set rates each year to fund pipe renewal, growth and debt on schedule, or smooth the increases by drawing on reserves, borrowing or retiming projects. Over 2024 to 2027 London's increases averaged 2.7% for water and 4.3% for wastewater, with swings from year to year.

Build plant and pumping upgrades at Oxford, Pottersburg, Greenway and Hyde Park ahead of demand, or hold development approvals where capacity is short until the work is done. The council policy targeted for the second quarter of 2027 will set the rule.

OPTION 3 OF 7

Replace lead service pipes faster

Add grants, targeted replacement or replacement on sale to London's loan-only help for the private side. Today the City replaces its side free when an owner replaces theirs, and lends owners of buildings with up to three units the private-side cost on the tax bill over 10 years.

What to ask your council

Anyone at City Hall can say this issue matters. These are the questions that ask for specifics. Send them to your councillor, or bring them to a committee meeting.

  1. Water and sewer bills rise about 5% in 2027 after a smaller increase in 2026. For the next four-year budget, would you raise rates steadily to keep pace with repairs and growth, or hold them down and delay projects, and which projects would you delay?
  2. The Oxford sewage plant is expected to run tight within two to three years. When a plant is near capacity, should new homes wait, should growth pay more through development charges, or should all ratepayers pay to expand sooner?
  3. London helps with lead pipes through a loan, not a grant. Would you keep that, add grants, or require replacement when a home is sold, and who should pay?
  4. About 50,000 homes still send weeping tile water into the sewer, which feeds overflows to the Thames. Should the City require disconnection, pay more of the cost, or keep it voluntary?
  5. Most properties under 0.4 hectares pay the same stormwater charge whatever their roof and paving. Should the charge depend on how much hard surface a property has, with credits for owners who manage their own runoff?
  6. If the Province offered or required a separate water corporation for London, what would you need to see on ownership, rates and accountability before supporting it?

These circulate in coverage of this issue but could not be traced to a source that loads and says what’s claimed. The site would rather show you the gap than publish the number.

  • Rated capacity and current flow at each of London's five sewage plants. The City publishes no plant-by-plant table.
  • A current count of lead services, public or private, and the yearly replacement pace.
  • 2025 plant bypass and overflow totals (the City's page lists data only to 2024) and any reliable 2023 total.
  • PFAS results for London or either regional plant.
  • The Ministry's numeric inspection rating for London and the regional systems.
  • London's share of the phosphorus reaching the Thames.
  • London's vote share on the Elgin Area board.
