Water Supply & Wastewater Systems

The infrastructure that supplies, treats, distributes, collects, and disposes of water used by major developments.

Understand what the system does, how design choices change impacts, and what records reveal the real operating profile.

System / technology

What it does

A project’s water footprint includes more than a single consumption number. Source capacity, treatment, pumping, storage, pressure, seasonal demand, fire flow, process requirements, sewer capacity, pretreatment, discharge limits, reuse, and drought conditions can all matter.

Impacts depend on scale, design, operating mode, maintenance, location, and the other systems this technology connects to.

Design matters

Common configurations

The same general system can produce different tradeoffs depending on which configuration is actually proposed.

Municipal utility service

Water and sewer supplied through existing or expanded public systems.

Private wells or intakes

Project directly develops groundwater or surface-water supply.

Reuse/reclaimed water

Uses treated wastewater or other non-potable supply for appropriate processes.

Onsite treatment

Project treats process wastewater or other flows before reuse or discharge.

Risk pathways

What can matter

Peak demand exceeding system capacity

Costly treatment/distribution/sewer upgrades

Groundwater or surface-water stress

Pretreatment or discharge-quality issues

Drought vulnerability

Rate impacts or cross-subsidy concerns

Questions to ask

  • ?What are average and peak demands by use?
  • ?What source provides the water?
  • ?What treatment and distribution capacity exists?
  • ?What fire-flow requirement must be maintained?
  • ?What wastewater streams are produced?
  • ?Is industrial pretreatment required?
  • ?Where does discharge ultimately go?
  • ?What reuse is technically and legally feasible?
  • ?Who pays for utility upgrades?
  • ?What drought or emergency restrictions apply?

Evaluation cautions & current applications

Evaluation cautions3 cautions
  • !Use peak and seasonal conditions, not annual averages alone.
  • !Separate potable/process/cooling/fire-flow demands because they may stress different parts of the system.
  • !A utility willingness-to-serve letter may not substitute for detailed hydraulic, treatment, and capital analysis.
