1.1 Purpose
This is the operations and maintenance manual for Lake Bennett Estate (Section 1252, 841 Chinner Road): a 64-bungalow community on the eastern shore of Lake Bennett that runs its own potable water, wastewater treatment, electrical distribution, and internal roads. It records how those shared systems are built, operated, and constrained by the Lake Bennett (Land Title) Act 2005 so the knowledge is not only in people’s heads.
Legal coverage and exclusions are in 1.2 Scope. Location, climate, and community context are in 1.3 Estate Overview.
Why This Manual Exists
Lake Bennett is not on urban water or sewer mains. Drinking water is bore-sourced, stored on the hill, chlorinated, and reticulated through isolation valves that can shut off groups of units. Wastewater from all 64 bungalows is collected through sewage pump stations, treated to Class A recycled water at an AdvanTex® plant, and disposed to subsurface irrigation — not to the lake. Grid power feeds the bores, lift wells, and treatment plant; a hire-generator inlet at DB1 is the storm / prolonged-outage path. Internal roads are the only access for residents, tankers, and emergency vehicles.
Those systems sit on common property, easements, and lots governed by the Act, the Articles of Corporation, and Development Permit conditions. This manual exists so owners, the Corporation, the caretaker, and contractors can:
- Operate and maintain the plant that is actually on site (not a generic “rural estate” template)
- Isolate faults, restore service, and call the right contractor without guessing
- Keep development, plumbing, and earthworks inside the rules that protect the lake and neighbours
- Hand over a consistent record when people, equipment, or procedures change

Manufacturer manuals, the OWMS O&M (ENVR V1.1), Acts, and drawings live under docs/assets/. Pages in this manual summarise what is needed on site and link to those files.
Who It Is For
| Audience | Use this manual to |
|---|---|
| Property owners and residents | Understand what is common infrastructure versus lot responsibility; conservation and connection rules; who to call |
| Corporation / estate management | Operate shared plant, coordinate contractors, keep records current, and apply development and easement rules |
| Caretaker and trained operators | Follow isolation, dosing, WWTP, and generator procedures; recognise alarms and contingency triggers |
| Contractors and service providers | Locate equipment, isolation points, and access; work to the documented plant, not assumed layouts |
| Authorities and certifiers | See how on-site water, OWMS, and development controls are documented against NT requirements |

How the Sections Work Together
The estate is one system. A change in one section usually has a counterpart in another.
| If this happens | It also involves | Documented in |
|---|---|---|
| A dwelling is built or altered | Dual approval (planning + Corporation), setbacks, connection to potable water and the effluent system, no work in easements without the service authority | 2.3 Zoning, 2.3.6 Compliance, 2.4 Easements |
| Potable water is lost or isolated | Hill tanks (gravity) can supply for days to weeks; bores and chlorine dosing need power; isolation is at the central box, Unit #17, and the western easement | 3.1 Water Supply, 3.1.4 Reticulation, 3.3.2 Backup Power |
| A sewage pump station fails | Zone 1–3 collection backs up toward bungalows; Pit 1 and Pit 2 typically need power within about 12 hours; contingency is in the OWMS O&M | 3.2 Sewerage, 3.2.15 O&M and Contingency, 3.3.2 Backup Power |
| Grid power is out | Bores stop; gravity water continues; wastewater pumps and WWTP do not. Hire generator at DB1; contacts and load priorities are listed | 3.3.2 Backup Power, 1.4 Contact Information |
| The lake must be protected | No effluent to the lake; 100 m setback for wastewater facilities; Class A subsurface irrigation; conservation on the potable side | 2.3.5 Environmental Management, 3.2 Sewerage, 3.1.5 Water Conservation, 3.2.9 Reservoir Impact |
| Tankers, desludging, or emergency vehicles need access | Internal roads, driveway standards, and designated emergency routes | 4.1 Internal Roads, 4.4 Emergency Access |
| Plant is upgraded or isolated for works | Owners need notice; isolation points and the generator path still apply | 5. Upgrades and Outages, 3.3.2 Backup Power |
The Interactive Map and 2.1 Master Site Map overlay infrastructure on the same land as the zoning and easement pages. Use them together when locating a pit, valve, or board.

Field Use
Each page has a QR code for phone access at the asset. Confirm isolation points and contacts on the page before work — layouts and contractor numbers change.
Document Status
This is a living record of the estate as built and as operated. Update it when plant is replaced, procedures change, contacts move, or a development condition is varied. Version history and the next review date sit at the foot of every page.
Superseded Plant
Legacy sewerage described in older reports has been decommissioned. Current wastewater documentation follows the AdvanTex® OWMS (ENVR O&M Manual V1.1). See 3.2 Sewerage.
Version Control
