Water Expanded

Survival

Version 2.5.5 · Updated Oct 28, 2026 · 512.4 MB · 11 downloads · WaterExpanded

The comprehensive Build 42 water, plumbing, irrigation and fuel-network overhaul. In Water Expanded, one server-authoritative WEX network connects pumps, valves, meters, seep channels, building-wide plumbing, storage, fixtures, gas stations and generators, with no bridge hub.

Pumps and pipes

Pumps, valves, flowmeters, sprinklers, filters and plumbed fixtures, with visible, concealed, vertical, iron, clay, irrigation, gutter and hose connections.

Water sources

Wells, natural-water intake, calibrated rain collectors, functional gutters, industrial tanks and portable storage.

Irrigation

Automatic crop watering, component-wide fertigation, and diggable seep channels fed by nearby natural water.

Building plumbing

Building-wide plumbing for any fluid, between real collectors and fixtures, including reserve collectors and mains reconnection.

Fuel routing

Physical petrol routing to gas stations and generators, plus a portable petrol-powered 5 L/min pump.

Purification and quick view

Purification tablets, chemical and heat treatment, clay filtering, and a water-drop quick view of nearby water, fuel and equipment.

What's new in 2.5.5

  • Build 42.22 (2.5.5) — Java plugin support for Project Zomboid Build 42.22.
  • Version proof (2.5.3, 2.5.4) — 2.5.4 adds a native modversion entry to both mod.info files so the installed version can be verified during world-pack sync, fixing the WORLD_PACK_SYNC_UNVERSIONED_MOD_CHANGED error; 2.5.3 was a version-bump republish. Gameplay is identical to 2.5.2.
  • Duplicate-folder fix (2.5.2) — installer 0.3.17+ removes an old mods/WaterExpanded copy after installing, fixing the Faded Java Loader "Conflicting duplicate Java plugin ID" error.
  • Stone cisterns (2.5.1) — 800 L underground and 250 L stone cisterns through the existing WEX collector service, physical storage and unified graph. Small-cistern lid actions keep water and collector policies.
  • Lighter networking (2.5.1) — batched endpoint replication, indexed building matching in Lua and optional Hybrid 1.0.2, fewer idle client scans and audio hooks, and debounced telemetry requests.

Requirements

Project Zomboid Build 42.20.0+ (targets 42.21.0). Optional Faded Java Loader Hybrid 1.0.2 acceleration with a complete Lua fallback. Server and clients need the matching 2.5.2 payload and a full restart; installer 0.3.17 cleans up the old WaterExpanded folder. Includes a KnoxNet OS bridge and a public physical-container API for other mods.
