Global water needs elevated to “critical condition”

News reports covering global water shortages like this one (click here) acknowledge the critical need for water in virtually in any country.

A sustainable water supply also requires affordable energy, as well as a local economy….yet some policies of the UN and some countries are self defeating….the need for drinking water will not go away….and in the past, the lack of water has resulted in people migrations….

Attempting to meet global water needs with expensive western technology are most likely to fail. Starting simple…as was done during the 19th and 20th century in the United States. Countries need to focus on developing solutions that are affordable and sustainable for their area of the world and locality, not on importing technology that will be stolen or not maintained or becoming dependent upon other countries.

United Nations wants global water management…

The United Nations is pushing for global water management…..Just another push for global control…..I hope this never occurs. Click here for more….

Hamas responsible for poor water, sanitation in Gaza

Despite the misdirected claims by aid groups, the Hamas terrorist group takes advantage of and holds out against its own people…..poor water and sanitation conditions in Gaza are squarely the doing of Hamas.  Click here for news article…..

Encinitas (CA) obtains low-interest loan for water plant renovation

Olivenhain Municipal Water District gets $17.8 Million state loan to help finance renovation of water plant.

This type of approach (government low-interest loans) is closer to being financially sustainable than a grant….however the money to capitalize the state revolving loan funds must come from somewhere…or else it is just printed (creating a currency risk) or it is borrowed from China, the Federal Reserve, or somewhere else.

The interest rate difference between what is paid to China and what the water district pays is the net cost to the rest of the country, plus the cost of government accounting and administration of the loans, which is not cheap.

Water districts should take advantage of such low interest loans (and grants) as long as they are available….but overall the current SRF system (water and wastewater) is not financially sustainable…..

   

Archer et al 2011: Field investigation of arsenic in ceramic pot filter-treated drinking water.

Ceramic pot filters (CPFs) is one of several household water treatment technologies that is used to treat drinking water in developing areas. The filters have the advantage of being able to be manufactured using primarily locally available materials and local labor. However, naturally-occurring arsenic present in the clay used to make the filters has the potential to contaminate the water in excess of the World Health Organization drinking water standard of 0.01 mg/L. A manufacturing facility in Guatemala routinely rinses filters to reduce arsenic concentrations prior to distribution to consumers. A systemic study was performed to evaluate the change in arsenic concentrations with increasing volumes of rinse water. Arsenic field kit results were compared to standard method laboratory results, and dissolved versus suspended arsenic concentrations in CPF-treated water were evaluated. The results of the study suggest that rinsing is an effective means of mitigating arsenic leached from the filters, and that even in the absence of a formal rinsing program, routine consumer use may result in the rapid decline of arsenic concentrations. More importantly, the results indicate that filter manufacturers should give strong consideration to implementing an arsenic testing program.
