Through Resolution of the Board of Directors No. 006-2021-SUNASS-CD, the standard was approved that regulates the issuance of binding opinion and determination of the maximum unit price in relation to the contracting of water supply or wastewater treatment services by companies that provide sanitation services.

In this regard, the following regulatory provisions on water supply stand out:

1. On the critical beneficiary sectors

Its identification will be associated with the quality of the source water and the indicators of coverage, non-invoiced water and / or continuity. 2. About the term of beginning of the benefit This may not exceed 36 months from the date of signing the contract with potential suppliers or, in any case, the time it takes for the company providing the infrastructure necessary to provide sanitation services in the critical beneficiary sectors, in accordance with the investment schedule developed in the evaluation and formulation phase (technical file or pre-investment study) or the work schedule developed in the investment execution phase (technical file or equivalent document), as appropriate .   3. About water sources The EPS should collect information on the historical variations of the physicochemical and bacteriological characteristics of possible water sources to determine the technologies of the alternative solution (s), always relying on the information provided by the National Water Authority. or the holders of the right of use.   4. Of the costs for the provision of the service The EPS considers 03 types of costs: a) The efficient cost of the temporary provision of the water supply service. b) If applicable, additional costs associated with the qualification and / or adaptation of its infrastructure to receive the water supply service.

Of the interconnection points The determination of the interconnection points is based at least on: a) The evaluation of the storage, treatment and conduction capacity of the components that will receive the volumes of water. b) Hydraulic evaluation of the conduction lines, impulsion, primary networks and secondary networks. c) Equipment evaluation. d) Cost analysis of possible renovations, improvements, as well as operation and maintenance costs.   Likewise, the following regulatory provisions for wastewater treatment stand out: 1. About the effective term of the service This is limited to the estimated date of entry into operation of the medium and long-term solution.

If the aforementioned costs are not foreseen in the investment program of the Tariff Study, their financing must be accredited.   4. About the interconnection points The determination of the interconnection points is based at least on: a) Analyze which contribution areas will be those that are isolated from the existing sanitary sewer system and will contribute their flows to be treated by the supplier. b) Analyze whether the supply flows for treatment by the supplier will receive the discharges from the overflows of water storage reservoirs. c) Hydraulic evaluation to determine how the different components of the existing sewerage system behave (secondary networks, main collectors, emitters, pumping stations, impulse lines, wastewater treatment plants) without the contribution of the flows of the areas isolated contribution. d) Analyze whether the interconnection points will be the existing mailboxes or special structures should be installed for this purpose. e) Cost analysis of possible renovations, improvements, as well as operation and maintenance costs.   The aforementioned resolution has maintained the regulation provided for in the Draft of norm published with Board Resolution No. 024-2020-SUNASS-CD on the determination of the PMU, its approval procedure and the corresponding confidentiality. Finally, it should be noted that the body in charge of preparing the PMU proposal is the SUNASS Tariff Regulation Directorate and will depend on each type of water source or each type of quality of the treated wastewater.
