Who is going to pay for the long term O&M (e.g., mainly battery and module replacement, etc.). What is their current source of water? Is their current water source treated? How? By whom?
What happens when the pump(s) crap out (every pump will crap out at some point)? Will the water charge (you will have one, won't you?) include O&M and eventual subsystem replacement cost?
Cheers, Rick

Hi Rick:
Thanks for the questions! Here are the answers provided by the Cambodian team:
Long term O&M will be taken care by the school water committees, using the project budget for O&M.
Well water pumped is their current source of water.

Hi,
did you think about a solar-powered pump instead of a generator?
Thanks,
Martin
Pump technology

A feasibility study must be carried out that suggests that a solar pump(s) could be a reasonable water delivery option under the following conditions, namely that the PV system were found to be competitive in terms of:
1) The upfront installation costs of the solar array, batteries (unless you intend to only run the pumps during the daylight hours), pumps, controllers, and water system manager(s), compared to using handpumps, diesel pumps, wind turbines (but unlikely in most areas of Cambodia), and hand pumps.
2) Training of local staff in module installation (generally easy), maintenance (largely battery management) and repair of electric pumps when necessary.
3) Long-term O&M costs (replacing PV modules, broken panels (a security issue rather than a construction issue (e.g., kids throw rocks, people steal batteries, etc.)
4) A detailed cost analysis should be carried out to determine whether the costs of the PV systems were truly competitive with diesel, gravity flow springs, or grid electricity (if available within a mile or two) are reasonably cost competitive in terms of installation and O&M costs.
5) People will need to be willing to pay for eventual purchasing of degraded battery banks. They would also need to pay an operator / watchman / O&M staff to keep on eye on things, and collect water tariffs over the long term.
6) People are willing to pay (WTP) for materials and equipment (mainly batteries) and replacement pumps (whose frequency of replacement is typically dependent upon the water quality and well depth).
7) WTP depends upon people's willing and ability to pay for water. If they already are paying for water from some other available source, the likelihood of them being willing to upgrade to a solar PV system to a cost competitive diesel, gravity, or handpump.
8) I'm not current on the solar radiation levels and capacity of solar pumps in Cambodia. You would need to reference long-term meteorological data (usually easy to find at the provincial level at least) to ensure that the solar electric generators would be sufficient to meet demand.

Solar upgrade

Thanks for this. Just to keep things a bit easier: There are lot's of experiences with Solar-powered pumps in other countries and assessing the feasibility sounds very complicated in your explanation. Just have in mind the framework you take into account in choosing fuel-powered generators nowadays...
I would prefer to fund a bit more and help provide real autonomy instead of fueling climate change, dependency on external imports of fuels, generators, spare parts etc. all needed with fuel-powered generators as well.
So caring for spare parts is not limited on solar powered systems. And: don't go for battery-banks as this is the only short-living part in solar-powered systems. Panels come with good glass-covers, radiation will do in Cambodia (as it does in Austria as well) and training (south-south) is already offered to lots of rural people (e.g. also Safer Future in Sierra Leone did Solar training for people from Nigeria, Sudan and now Tanzania). Don't choose old-school technology for people in poor or rural areas, choose a simple and reliable technology.
budget & survey and tracking of past projects
By Project Well Posted on Mon 02 Aug 2010, almost 16 years ago
1. Would be helpful to see a detailed budget in excel format for instance installation of the UV system is 4,833 and the deep well is 1450 do these include only the material if what because labor is listed as separate.
2. What is the signboard and why is it so expensive?
3. Could you please explain what is the 'public announcement for bidding'?
4. What would be the maintenance cost?
5. The study that will be done is to assess the health conditions of the students and teachers including attendance record before and after the installation of the UV plant. Would you also consider the water (and food) consumed at home or elsewhere other than school?
6. How do you track the historical projects for instance that of Safe water system at Mai Hoa that was supposed to be completed in December 2008?
Can you direct me to some of the reports of:
Safe water system at Tan Hoa
Safe water system at Loc Thuy.
Thank you
Meera

I may have missed it, but where are the water quality testing results and cost for the analysis?
How often will they do water quality testing (World Bank and ADB projects usually require WQ testing every six months)? Who will pay for this?

I assume that there will be open and competitive bidding for the construction of the PV (not "UV") power supply and the water filtration and control system.
EMW should stipulate the estimated monthly and annual operation and maintenance cost projection, so that users will be better able to assess their willingness and ability to pay for long term system use, including estimated system expansion over time.
I don't know anything about the signboard. Perhaps EMW (Mrs. Tam) could answer that question.
Water consumption at school is easy enough to measure, and necessary to set a reasonable tariff. I see no reason whatsoever to measure food intake. That is not relevant for this project.
It's fine to track health conditions of the project beneficiaries, but that should be done by the local health officials, not the project. My understanding is that the focus is on providing good quality, reasonable cost water supply, not to carry out health surveys.

Hi Rick, To see the effects of water through health studies one need to do a recall of at least 2 weeks of sources of water and food especially if the subject has diarrhea in the past 2 weeks because diarrhea is caused by contaminated water and food. You are right to see the effectiveness of the new water system a research team should be involved funded by other organizations. Thanks for your input on this panel. Meera

Thanks for your questions. The Cambodian team provided the following answers:
2. • The unit cost of standing signboards: 1m² = $50 (for 2 m²)
• Two metals stands: $20
3. "Public announcement of bidding" usually means announcing the bidding package for the project on public mass media (either local/national/international newspapers, television, internet or public meetings, etc.)
5. This project is focused on school-related activities only.
6. We will post the reports of the completed projects (including Tan Hoa and Loc Thuy) onto PWX website and will notify you when that is done.
