Cost Estimating for SWS


Sources of Cost Information


4. 5. 6. 7.

Technologies and Costs Document for the Final Long Term 2 Enhanced Surface Water Treatment Rule and Final Stage 2 (Dec 2005) Disinfectants and Disinfection Byproducts Rule Journal articles, papers, reports. Other Engineering Reports performed recently RS Means and other cost estimating tools Discussion with water agencies in the area Contact the vendors (AWWA Sourcebook) Contact the contractors

Fluctuations in cost



Materials markets are fluctuating. Steel and other metals are difficult to project. Vendor quotes usually are the best source of current information.


How does this impact cost?
Example: Steel storage tanks
Relationship between area and volume
$100,000.00 $90,000.00

Tank Volume v.s. Cost

Step1-Provide a Scope for Yourself

 


What problem are you solving? Is there an opportunity to consolidate? Is there an opportunity to find a new source? What needs replacement? Provide a list. What is new? Provide a list. Provide rough layouts.
  

Is there enough room on-site? Does it require a building? Is there enough power on-site?

Step 1-Provide a Scope for Yourself


Are there sanitary hazards near-by? Are there similar facilities near-by that you can visit?

  

 


Are their sensitive environmental issues? Is it remote? Is availability of telephone lines for telemetry a problem? Are there all year roads? How will you handle wastes generated? Avoid temptation to use band aids (solve the issue for next 20 years) How available are skilled operations staff? Remember you can be held liable for your decisions.

Step 2-Provide Rough Layouts

Operations Building

Storage 60’

Step 3-Provide a list items for yourself
Example: 1. Expand the existing gallery by an estimated 20 feet. 2. Add 50,000 gallons of storage improvements to the existing storage for an overall 90,000 gallons of storage. 3. Provide a Pall AP-1 or equivalent membrane treatment system. 4. Re-plumbing changes to include treatment system. 5. New building improvements. 6. Monitoring equipment (turbidimeter, chlorine residual analyzer, pH, temperature) 7. Provide back wash decant and percolation pond.

Note: Actual costs should be verified by local drilling company


Hydro Pneumatic Tank Cost
  

$10 to $15 per gallon for 1000 gallon size. $2 per gallon for a 50 gallon tank size. Use $150 per year O&M for 1000 gallon size range.


 



Check with pump supplier. General rule of thumb is $1000 installed for smaller size range around 50 gpm dual pumps. General rule of thumb is $10,000 to $15,000 for 100 gpm dual pumps. Allow $15,000 for a PG&E power drop if power is not available (200 foot range).

Pipe Installation
    


Check with local contractor. Rule of thumb for 4 to 6 inch range is $40 per foot. Rule of thumb for 8 and 10 inch size is $50 to $60 per foot. Rule of thumb for 12 inch is $100 per foot. This includes pipe fittings. Add 25% for seismic installation.

Other Water System Components
 


Use $5,000 for hydrant installation. Pressure regulators including box cost $25,000 per unit (8 inch pipe size rangeregulator is actually 3 inch range). Household connection cost $1,500 including meter per connection installed.


General Guidance



Contact vendors as needed to tie down component costs. Contact local contractors as needed to run cost opinions by them. Use pre-package units and avoid temptation for custom design which is more expensive.


General Approach to O & M Costs

 

  

Determine list of general activities Determine anticipated hours per year for each activity. Determine hourly rate for trade required. Determine list of direct annual charges for permitting and fees. Review sample plans to determine analyses to be performed. Use certified laboratory list of analytical charges. Include shipment fees for samples. Use unit costs per 1000 gallons for various treatment technologies to verify your costs. Don’t forget any disposal costs!
