locally)
ii. what is the maximum pressure for these pipes/valves
e. Tap locations
i. Where will the taps be located; how many people will use each tap
ii. Will taps be installed in households or in a central location
 If household taps are used, Chapter must consider wastewater
issues, impact of additional water usage, who gets water first, etc.
f. Wastewater
i. With more water, there is more wastewater, consider how will this be
treated/channeled; are there any additional health risks associated with this
water (i.e. Malaria)
g. Water source

III) Sanitation
1. Background Data
a. What is the source of the wastewater, i.e. toilets, washwater, greywater
b. Can sources of wastewater be segregated to simplify or reduce costs of
construction and maintenance
c. Source separation or segregation of wastes can reduce the volume of water
requiring treatment and the resulting expense and influence the type of treatment
needed to purify the water, for example:
i. Feces could be collected and separately treated in a pit or composting latrine
ii. Urine can be separated and beneficially used for fertilizer
iii. Greywater (water only used for washing dishes and bathing) may require
less treatment or a smaller treatment area that water bearing feces.
d. What quantities of waste (solid or water borne) will be generated; volume/mass of
feces and urine, as well as materials used for anal cleansing (paper, water, plant
materials, etc) need to be considered
e. All systems generate solid waste materials or biosolids - methods to collect and
reuse biosolids needs to be included:

iii. Accessibility of the facilities
iv. It is possible to design a great system that will not get used, due to cultural
habits, taboos, fears and inconvenience
b. Technical alternatives to be considered and evaluated include, but are not limited to:
i. Pit latrine
ii. Ventilated pit latrines
iii. Composting latrines
iv. Water privy
v. Pour flush latrines

Page 8 of 22
505 – Site Assessment Form
Revised 09/2014

ii. Venting to control odors and enhance biodegradation of the feces and
evaporation of urine
iii. Insect and rodent proofing
iv. Adequate slope to drain away from the superstructure
v. Type of covering over the vault
vi. “squat plate”
vii. Depth, volume and lining for the pit
viii. Distance from water sources and wells
3. Waste Treatment
a. Water latrines and pour flush latrines rely upon treatment and dispersal of
wastewater into the surrounding soils
i. If the system will rely upon soil treatment (e.g. a “leach field”, pour flush
latrine, seepage pit), are the soil conditions and available area for infiltration
conducive to this type of treatment
ii. Subsurface conditions that impact performance and must be considered are:
 Soil types/percolations rates - soil can be classified using the U.S.
Department of Agriculture (USDA) textural triangle into sandy loams,
loams, and sandy clay loams or using the Unified Soils Classification
System (USCS) into SW, SC, CL, CH, etc. In areas where pan
evaporation exceeds precipitation for most months soils classified as
clays (CL, CH) may require large absorption systems or the use of an
evapotranspirative type of system; A quick percolation test can be
performed in possible disposal area(s)
 Depth to groundwater - a minimum of 12”-18” separation between the
infiltrative surface of the leach field and groundwater is required; if
depth to groundwater is unsatisfactory, a mound system may be
utilized, provided there sufficient quantity of fill soils to create a
mound
4. Construction, Collection and Conveyance
a. Are sufficient materials, labor, and equipment available to construct the components
of the treatment systems; for example:
i. Concrete and wood forms for a septic tank,
ii. Sand for sand filters
iii. Mortar and bricks for a seepage pit or vault.
iv. Piping to convey wastewater to the treatment system
v. Labor and equipment to excavate pits, pipeline trenches, leach fields

Page 9 of 22
505 – Site Assessment Form
Revised 09/2014
vi. Wood or brick for privy superstructures
b. How much pipe will be required to convey the wastewater from the source to the
treatment system - the cost and labor of a system will increase significantly with
systems that require a lot of piping
i. Latrines require little piping,
ii. Septic tanks with SBAS may require more piping
iii. Lagoons and constructed wetlands may require even more pipe to deliver
the wastewater from the source to the treatment system
5. Environment
a. Will the system prevent or minimize contamination or further degrade the receiving
waters (surface lakes, streams and groundwater)
b. Is the level of treatment provided by the system sufficient to prevent degradation of
receiving waters
c. Can water be re-used for beneficial uses, e.g. crop irrigation
i. In areas with plenty of rainfall, reuse of the wastewater may not be worth
pursuing; however, in areas where water is scarce, reuse should be carefully
considered
ii. If wastewater will be re-used, the uses of the water will significantly influence
the degree of treatment and performance assurance of the system must be
carefully considered.
iii. If the water can be re-used, how will the water be stored and applied to
crops
d. Consider whether gas from biological treatment processes can be collected and
used for cooking and heating (biogas plant), possibly including animal waste
6. Overall Considerations
a.
b.
c.
d.
Is the project feasible from a social, economic, technical, standpoint
Is the project “buildable”
Have several alternatives been considered
The ideal solution for a project may require a single system, e.g. vault privy, while
other situations may require a combination of systems; several alternatives should
be considered following the site assessment

V) Energy
1. Solar
a. The following primary guidelines MUST be considered for the assessment of any
solar project:
i. The risk of theft and vandalism is inherent to any solar project. As such,
many NGO’s have a policy of not implementing solar projects in developing
communities. Chapters must develop a comprehensive plan for mounting
and securing panels in order to prevent theft and damage
ii. The brand and model of panel being installed must be available from an incountry distributor. Additionally, all maintenance and replacement materials
must be available locally including mounting, sealant and electrical
equipment.
iii. A cost-benefit analysis must be carried out for all energy alternatives.
b. Other considerations:
i. What equipment will be powered—is this considered a basic need?
ii. What is the needed kWh output and how will this vary throughout the year
What is the latitude and longitude of the community
iii. How will the output of the system vary throughout the year
iv. How many cloudy days
v. What equipment is available locally
vi. Where will the solar panels be placed
 What angle will result in maximum efficiency
 Can the panels be roof mounted or will some sort of ground mount be
needed
 What materials are available for this
 For roofs: can the roof support a worker’s weight, what reinforcement
will be needed for the roof so that the panels can be mounted
 Is there any shading (even a very small amount of shading can
severely reduce the panel’s output – make sure to read about this)
 If there is shading, can the obstruction be removed (i.e. cut down the
tree), is yes, who will do this and what impact will it have
vii. Distance from the panels to the batteries or grid tie
viii. How will the power be routed to the batteries, converters, loads
c. Batteries
i. Where will the batteries be stored
 What ventilation is available (the build up of hydrogen gas is a
hazard)
