This is an outsourcing that has been conventionally carried out under responsibility of the public water utilities.
This refers to outsourcing that has been conventionally performed under the responsibility of the public water utilities (water supply operators).
Basically, it is based on “specification orders”, but in recent years, as a method of utilizing the originality and ingenuity of the consignee (private sector), there are “package orders” for tasks that are strongly related to each other, and “performance orders” with the required level of work as the contract responsibility.
Scope of responsibility
All responsibilities under the Water Supply Service Act lie with the public water utility (water supply operator) , and the contractor (private water supply provider) has contractual responsibilities under private law.

Q. What types of order methods are available for the public water utility (water supply operator) ?

Contract determination methods Outline Merits Demerits
Open competitive bidding
  • Bidding in which people who satisfy certain participation requirements can participate in the competition freely.
  • The person who participates in competition and bids at the minimum price is determined as the successful bidder.
  • Fairness and transparency of bidding are high and monitoring by third party is easy.
  • It is possible to select a vendor with emphasis on cost reduction by maintaining high competitiveness.
  • It is difficult to eliminate bad and disqualified vendors.
  • A person who is not capable of executing business may make a successful bid and quality of work may be degraded.
  • Damping caused by excessive competition may occur.
Selective bidding
  • The procuring service selects specified persons who are considered as applicable with conditions including technical strength, financial power and credit and the person who makes a bid at the minimum price is determined as the successful bidder.
  • Reliable contractors are selected.
  • Certain competitiveness is ensured.
  • Number of competition participants is limited, thus competitiveness becomes low compared to open competitive bidding.
  • Participants are appointed regardless of intention to participate in competition, thus the number of persons who reject bidding increases.
Comprehensive evaluation bidding method
(Open competitive bidding and selective bidding)
  • The person whose conditions including technical strength were the best among people who tendered a bid within the predetermined price range is determined as the successful bidder.
  • The person who made the bid at the minimum price does not always make a successful bid, thus sound vendors having technical power can be developed based on this system.
  • Discussion is held by an unbiased evaluation committee, thus bad and disqualified vendors can be eliminated.
  • Selecting and securing people of experience or academic standing are required.
  • Selection capability of procuring service is required when evaluating technical power of participants.
  • Procedures for making a bid and concluding agreement are complicated, thus it may take time to complete the contract.
Proposal system
(private contract)
  • Applicants are selected based on the technical proposal and the person whose proposal had the highest rating is determined as the person who has the highest refusal right.
  • Consignee can be selected by putting emphasis on contents of proposal (technical power, etc.).
  • Flexible order range is possible because inventive ideas in the technical proposal can be adopted as addition of specification.
  • Selection capability of procuring service is required when evaluating technical power of participants.
  • Cost for preparing the proposal is charged to participants, thus certain financial ability is required and the number of participants may be limited.

Monitoring system for solar power (stand-alone power source)

This system allows the Web monitoring and measurement by installing a package consisting of stand-alone power source - "solar power unit", measuring devices and wireless communication unit. This was developed for locations where there is no power supply and measurement monitoring is not possible such as a water reservoir in remote mountainous area.

Stand-alone power supply system
Constructing the monitoring system of facility information (water level, flow rate, turbidity, temperature and opening, etc.) by using natural energy (sunlight)
Minimum remote monitoring device
Remote terminal unit data could be browsed through minimum IT gears such as PC, mobile phone and iPad, etc.
Equipped with multi-functions
Streaming of video images through the web monitoring camera
