BaySeparator: Stormwater Treatment

The problem

Storm water is one of the main causes of pollution in cities. All the water runoff that is produced accumulates waste and pollutants throughout the city and is finally poured into rivers and water bodies, affecting environments and natural resources that people depend on.

The technology

The BaySeparator is a water treatment system that treats runoff throughout entire storms, no matter their intensity and duration.

In the following link it is explained how it works with different storm intensities:

The stakeholders

  • Municipalities
  • City governments
  • Water treatment institutions
  • Citizens

Deployment

BaySaver Techonogies Inc. is a company that designs and manufactures stormwater treatment products. They created the BaySeparator in order to improve older systems that treated only the first flush of runoff. The idea was to create a new technology able to treat the stormwater throughout the entire storm.

Parabosol: providing safe drinking water in remote areas

Technology: Parabosol is a portable solar powered water treatment system for use in remote areas.

  • Physical and purifying filtration is conducted by using a parabolic mirror that boils water at a temperature up to 400 degree Celsius.
  • The water first passes through a sand filter to catch particles.
  • Secondly, the water is collected in a water container where it is purified using the steam generated by the parabolic mirror.
  • And lastly, the water passes through a carbon filter to remove odor-dissolved gases.
  • The system consists of one contaminated water container, one purification container and two clean water containers.
  • This technology can clean up to 170 liters of water in a single use.

Problem:

  • Statistics vary but the WHO states that “1.1 billion people has no access to any type of improved drinking source of water.” http://www.who.int/water_sanitation_health/mdg1/en/
  • water.org puts this figure at about 663 million people that lack access to safe drinking water (about 1 in 10 people)
  • A lack of safe drinking water has a strong impact on health and mortality as can be seen by the millions of people who suffer from waterborne diseases.

Stakeholders:

  • Engineers / Designers of the technology
  • Suppliers of materials
  • Sales and marketing
    • Who can sell this technology and get additional funding/investment
  • Investors
    • who can finance the implementation of these solar panels
  • NGOs and project managers
    • who can help assist with the implementation through actual installation, maintenance and education of communities for how to maintain it themselves
  • Local communities
    • who will be benefiting from this technology also need to be receptive to it.

Implementation:

It is unclear what stage this technology is in with regard to implementation, however it did win awards in 2014 and 2015.

A plausible implementation process for such a technology, however, would be:

  • Seek funding and investments to launch a pilot project
  • Partner with an NGO that has ties to a community where it could implement such a technology
  • Launch pilot project and monitor outcomes / problems that arise
  • Made adjustments to technology/ additional R&D
  • Marketing of success of pilot / get additional funding
  • Continue partnership and implementation across communities
