Alaska Water and Sewer Challenge

Project Highlights

At a public event, the Alaska Department of Environmental Conservation Village Safe Water Program announced the beginning of Phase 3. Please click on the link below to download the presentation slides and access our Press Release.

Public Presentation held in Anchorage, AK on December 8th, 2015

During Phase 3, the top three selected proposals will be funded for prototype development and pilot testing in a laboratory setting. The three teams have up to 7 months for setting up their prototypes. Once systems are up and running, they will be monitored and tested according to technical specifications provided by ADEC. Progress reports will be submitted by teams on a monthly basis during the required 9-month testing period. A final report will be submitted by each team, three months after monitoring and testing has ended. We are expecting to collect all three final reports by the end of summer 2017. Please click on the link below for an overview and schematics of the three pilot systems.

About this Project

To improve the health of rural Alaska residents, the Alaska Department of Environmental Conservation, in coordination with tribal, state and federal agencies, is spearheading a research and development effort to find better and more affordable ways to deliver drinking water and sewage disposal services to rural Alaska.

The Problem

  • Over 3,300 rural Alaska homes lack running water and a flush toilet. Many more depend on aging and deteriorating piped and haul systems.
  • Lack of in-home water and sewer service in rural Alaska causes severe skin infections and respiratory illnesses. Residents of Southwest Alaska suffer rates of invasive pneumococcal disease (IPD) that are among the highest in the world.
  • To correct this public health problem, agencies have funded conventional, community-wide piped and truck haul systems. Although these systems work, they are expensive to construct and many communities cannot afford their high operational costs.
  • Funding to build systems has declined severely while costs have risen sharply. The deficit between available funds and needs is over $660 million.
  • Many households in rural Alaska use a toilet known as a "honey bucket". A plastic bag lined bucket collects urine and feces. Then, plastic bags of feces from honey buckets are disposed in a sewage lagoon.
  • A different approach to delivering these services is needed.

The Solution

The Alaska Department of Environmental Conservation has initiated a project to spur worldwide research to develop innovative and cost effective water and sewer systems for homes in remote Alaska villages. The project focuses on decentralized water and wastewater treatment, recycling, and water minimization. These approaches have a high potential for use in individual homes and housing clusters. Our goal is to significantly reduce the capital and operating costs of in-home running water and sewer in rural Alaska homes.
