to investigate potential sites and supply area in order to evaluate the
feasibility of projects and get information for electrification planning.
Activities in site reconnaissance are :
to measure water discharge and head that could be utilized for micro-
hydropower generation.
Investigations of intake site, waterway route, powerhouse site and
transmission route etc.
Power demand survey.
Collecting socio-economic data such as number of households and publicfacilities in supply area, availability of local industries which will use
electricity, solvency of local people for electricity and the acceptability of local
people to the electrification scheme.

As advance information, 1/50,000 topographic maps are prepared to
check the topography of the target site and villages, the catchment
area, villages distribution and access road. More accurate
information on site accessibility could be collected by contacting
local people concerned
Check list and interview sheet are also prepared for each site
reconnaissance.

(1) Access conditions to reach project site & transportation of equipment
(2) Situation of existing system and future plan.
(3) Situation of river water utilization
(4) Existence of other development plans/projects in terms of roads,
farmland, housing and tourism, etc. which may affect the planned project
site and/or its surrounding area.
(5) Civil structures in adjacent area and materials used. Most civil structures
of a micro hydropower plant are similar to those of irrigation facilities and
road drainage facilities. The materials used for these structurers are often
available or can be obtained near the planned project site.
(6) Presence of natural topographical features and existing structures usable
for power generation. When an existing irrigation channel or similar is
used (including widening and/or reinforcement) as a waterway for powerstation, it is necessary to check the cross-section, gradient and current
water conveyance volume, etc. of such a channel.

1. Topography survey to establish a waterway
route and other relevant information for theplanning of a micro-hydropower plant.
2. Measurement River Flow. However, when river
flow data is difficult to obtain, it is preferable to
measure the river discharge in the dry season,
by means of simple method, to confirm the
appropriateness of the estimated flow duration.
Ideally the project can derive Flow Duration
Curve for better design.
3. Measurement of Head. The head between the
intake point and the headtank and the head
between the headtank and the outlet point
should be measured. At the initial planning
stage, however, it may be sufficient to measurethe head between the planned headtank
location and the outlet level.
4. Demand Survey :

9/20
(1) Location
The suitable route and distance, etc. to each power
demand facility should be surveyed to examine theoptimal transmission and distribution lines.
(2) Owners
The opinions and intentions of the owners of power
demand facilities regarding the introduction of a new
power supply source should be clarified.
(3) Types and required quality of equipment
The situation of power use by equipment (for power,heating, lighting and electrical control, etc.) and the
required level of accuracy (in terms of the allowable
voltage fluctuation and frequency fluctuation) should be
surveyed.
(4) Equipment capacity, etc.
The equipment capacity, power consumption level and
electricity tariff (or estimated electricity tariff in the caseof planning) should be surveyed.
(5) Likely problems associated with power cut
The likely problems and financial losses associated with
a power cut to power demand facilities should be
surveyed.
